Ordinary diesel engine camshaft is driven by means

Ordinary diesel engine camshaft is driven by means of high-pressure pump diesel fuel delivered to each cylinder chamber. This approach to oil changes with the engine speed changes, the optimum amount of oil can not do all kinds of speed. And now more and more widely used in electronic control common rail diesel injection system can better solve this problem. Common rail injection fuel system from the high-pressure pump, public automatic fuel dispenser supply tubing, fuel injectors, electronic control unit (ECU) and a number of pipeline pressure sensors, the system each injector through their high-pressure tubing and public supply tube connected to the public for the pipeline for injector has played the role of hydraulic accumulator. When working, high-pressure pump to the high pressure fuel delivery to the public for the pipeline, high pressure pumps, pressure sensors and ECU composed of closed-loop operation.

Display dispenser manual mechanical vacuum pump technology

With the operation and the pump oil circulating pump, in return for high vacuum end will re evaporated into steam. Will affect the pumping performance, increase the pump oil pollution. Set the gas ballast valve can effectively prevent the condensation of condensable gases, namely the display dispenser in the compression process, gas ballast valve gas dispensers through the gas hole of the permanent dry gas mixed with compressed gas, condensable gas partial pressure in the pump when the temperature reaches the saturation vapor pressure, pressure display dispenser of compressed gas can reach exhaust pressure, exhaust valve is opened, the condensate and dry gas discharged simultaneously. Normally the oil seal mechanical pump gas ballast valve are arranged, it can refer to the manual mechanical vacuum pump oil seal technology. This pump is easy to return oil and fuel injection, in order to overcome these shortcomings, the manufacturer at the same time with the molecular sieve, oil mist collector, dust filtration and oil filter and other accessories.

Petrol dispenser pump automatically change the fuel supply

Petrol dispenser pump due to work pressure, requiring the relevant parts with high structural strength and stiffness, so  relatively heavy, bulky; fuel injection pump and nozzle manufacture high precision, so the higher costs; addition, engine rude, noise and Vibration large; not evaporate, winter cold car difficult to start. Because of these characteristics, the previous engines are generally used for large and medium-sized heavy-duty trucks. The new development of small high-speed engines: the European III emission standards have been reached number. Traditionally, due to relatively heavy engines, liter gasoline engine power indicator gas transfer pump is better (lower speed), high noise, vibration, soot and particulate (PM) emissions of more serious, it has been rarely cars of all ages. But with recent advances in technology, especially the new development of small high-speed petrol dispenser pump engines, a number of advanced technologies, such as electronically controlled direct injection, common rail, turbocharged, intercooled and other technology to the small engine applications that shortcomings exist in the original engine to get a better solution, while advantage in energy efficiency and CO2 emissions, it is all heat engines, including gasoline, including irreplaceable, therefore, advanced small high-speed engines, which Euro III emission standards have been reached number, a "green engine" has become a new power plant in many European and American cars, it is foreseeable that China will be more and more cars. In fact, the working process of the diesel engine with the same gasoline engines, each working cycle also experienced intake, compression, for power, four stroke exhaust. However, due to the fuel is having a viscosity larger than that, does not readily evaporate, but the autoignition temperatures are lower than that of gasoline, thereby forming a combustible gas mixture and the ignition mode are different from the gasoline engine.

Petrol dispenser pump is commonly used parts distribution network in

On the interface device audio and video signal petrol dispenser pump is assigned to multiple display devices or projection display a control device on the system. It is specifically allocated signal interface in the form of equipment. Which can be received on the local display, the other can be connected to the remote display device, by adjusting the brightness and contrast on the petrol dispenser pump, you can put the remote display device to adjust image sharpness to the local same effect. Through the adjustment, remote display image quality will improve the quality of the equipment, the petrol dispenser pump can maximize the elimination of de-tail and ghosting, fully meet the current key projects of various high quality image quality.

Car overfilling, will lead to direct access to the car into the airway caused by the so-called spark plug, a direct impact on vehicle driving performance. Performance is: acceleration will turn off, or even unable to start such serious consequences. It is also possible that heavy duty fuel dispenser from the carbon tank overflow, will cause environmental pollution and fuel waste and other consequences. Small is harmful to the car, the big cause pollution to the environment.
Experts also suggested that in the refueling to fill the time when the slow enough to fill too fast, then the expansion of steam plus gasoline out of the gas too late to release, but also produce choking oil. Therefore, we must bear in mind that when refueling must be in accordance with the instructions on the fuel tank volume refueling, absolutely can not exceed this standard fuel, so as to avoid hidden dangers. Warm remind you, if you often walk in the city, there is no need to add the gasoline over, it is recommended to add about two-thirds. As the city in the china fuel dispenser evenly distributed, and there will not be found in the phenomenon of gas stations.

It is strictly forbidden to use communication tools in refueling and gas pump filters areas. In the explosion-proof area to fight the phone, because the phone press the switch moment to produce a slight spark, or old phone line aging, the use of the process may also produce sparks, which will cause an explosion. In addition, when the gas station through the oil gun to the car or motorcycle fuel tank injection, the original empty tank calibration software of oil vapor will be drifting out, coupled with the new injection of gasoline is also volatile to the air, so that the fuel around the vehicle oil Steam density surge. If you encounter air humidity, low pressure cloudy or foggy weather, poor air circulation, oil and steam density corresponding increase, then hit the mobile phone to cause the possibility of explosion will be further increased.

The main purpose of the electronic diesel fuel pump seal is to isolate the contact between the oil vapor and the spark. Specific sealing parts include computer control box, computer box and mechanical box separator and explosion-proof junction box.
The above-mentioned sealing parts mainly use rubber strips, rings, etc., by the climate and the impact of the scene, rubber products will appear thermal expansion and contraction, aging cracking to seal failure. Therefore, it should be in accordance with the daily inspection requirements of regular inspection.
1. Computer cover and installed in the panel on the components and the lid between the seal, shall not appear notch, deformation and obvious different thickness.
2. Computer box and mechanical box between the partition cable, pipe through, the seal can not be loose, deformation and fall off, check the feel must be tight, strong.
3. Strong, weak explosion-proof junction box is generally in the bottom of the gas station management software oil vapor often gathered in the place, the seal by the seal and bolts to protect. Therefore, it is necessary to ensure that the seal is complete and bolted.

The marine fuel dispensers circuit includes power, control, pulse, display and lightning protection, anti-static circuit, which mine, anti-static circuit is the focus of attention.
Circuit hidden trouble is not easy to detect, because the electricity is invisible, in addition to the occurrence of power short circuit, circuit or voltage instability, etc., will cause the fuel dispensing meters dysfunction and was found, the electrostatic ground contact bad or virtual connection, usually does not fail , And by the human senses can not be judged, so easy to be ignored. Therefore, we must use a multimeter, according to the provisions of the time interval to detect, the general site refueling gun to detect once a month is appropriate, the seaside and more serious corrosion areas, should improve the detection frequency to once every half months.

Self-service tanker use steps:

In the fuel transfer hand pump before the need to pay attention to the car to find the oil gun before the label, to avoid the wrong oil,
1, hand touch static electricity
In accordance with the fuel instructions, the first step should be placed in an electrostatic discharge area, the body may eliminate the existence of static electricity, to avoid the danger caused by refueling.
2, set the amount of fuel
The second step is to set the amount of fuel.If you use the fuel card refueling, insert the fuel card directly, and click on the screen "fuel card" option. At this point the side of the screen will display the card balance, we can according to their own needs Select a fixed amount or fixed fuel two modes. After selecting the click button to start the refueling.
If we use the cash to refuel, you have to see the instructions on the tanker, use the specified face value for temperature probe calibration, while the notes are not too old, otherwise many machines will not recognize the input banknotes and enter the amount can start refueling, the process Feeling and using ordinary drink vending machines are not much different.
3, began to refuel
Refueling process is not difficult, off the car, open the fuel tank cover, pull out the fuel tank into the fuel tank, press the handle to start automatically refueling, this process is fully automatic, refueling to achieve the default amount will automatically jump gun, no If you need to put the refueling gun back to the tanker to complete the refueling.
At the same time to remind the oil guns have a fixed locking device, refueling process without manual press, but each gas station oil guns will be nuanced, this need to show the specific circumstances, but even if the lock mechanism is not found Worry, manually press the same fuel can be safely operated, to achieve the default amount of oil gun will automatically stop refueling.

Analyze and summarize the common faults, and then solve the problem.

First: small flow is not self-styled
The reason is that in the small gasoline flow meter, the flow rate is low, the suction effect is small, the pressure difference between the upper and lower chamber of the switch film is small, can not overcome the elasticity of the spring so that the self- To solve this problem, it is necessary to reduce the spring force of the spring.
Second: refueling guns are not self-styled
The reason for this is that the upper surface of the diaphragm is sealed with the outside, for example, the upper part of the plastic cap is not tightened, and the "O" type seal on the adapter and the sub-seat of the oil gun is damaged. The diaphragm can not form a pressure difference. To solve this problem need to tighten the plastic cover pressure wire, replace the "O" seal.
Third: refueling guns often self-styled
The reason is that the nozzle inside the electronic diesel fuel pump is blocked by foreign body, poor air intake or open the membrane on the cavity of the spring caused by the spring is too small. Solution: clear the foreign body in the intake pipe, stretch the spring to enhance the elasticity.

Analyze the precautions regarding the use of the dispenser valve.

   1, please do not apply fluid other than fluid.
   2, do not use the maximum use of pressure restrictions.
   3, do not use outside the use of temperature range, to prevent the sealing material caused by wear or leakage.
   4, do not carry out artificial hit, bending, stretching, to prevent damage caused.
   5, do not mix in metal powder or sand dust and other diesel fuel flow meter to use, to prevent poor work or leakage.
   6, the installation of the thread, do not exceed the maximum tightening torque installed to prevent damage caused.
   7, do not use cracks with the hose, to prevent leakage or fall off.
   8, such as for vibration, the impact of the machine will cause reduced durability.

What are the working materials for the tanker?

First, the oil marine fuel dispensers
1. Small tanker after the gun, the signal sent to the electrical room of the electromagnetic switch
2. Electromagnetic switch action, the 220V power supply to the sinking pump
3. After the oil pump moves, the oil is piped to the tanker
4. The oil of the small tanker is filtered by the filter and flows into the flowmeter when the solenoid valve is opened
5. After the oil flow meter:
(1) oil along the leather tube, from the device, oil gun out of oil. (2) flow meter action, the pulse generator to send signals to the electronic board measurement
Second, self-priming retail fuel dispensers
1. Small tanker after the gun, the signal sent to the tanker electronic board
2. Small tanker electronic board to send signals to the motor power board
3. Motor power supply (110V or 220V) to the motor
4. After the motor action to drive the pump, the pipeline will be oil from the tank to the tanker
5. After the oil is filtered through the filter, when the solenoid valve opens and flows to the flowmeter
6. After the oil flow meter: (1) oil along the hose, from the device, oil gun out of oil. (2) After the flowmeter moves, the signal is transmitted by the pulse generator
automatic fuel dispenser by the computer will be stuck ash processing after the boot signal to start the motor, and the measurement of the original data back to zero, while the motor drive pump rotation, the oil into the oil and gas separator, separated by oil and gas, into the The meter measures and delivers oil to the oil container through the hose and oil gun.

Tanker tanker used;
(1) on-board pump refiner Oil and gas separator is equipped with a filter, which consists of copper wire mesh and felt mesh sets, the separator side wall has a triangular cover can remove the filter. The filter of the combined pump refiner is installed in the inlet port. Submersible pump type tanker installed with a special filter box, open the end cap to remove the filter. The filter should be cleaned regularly (at least once a month) with gasoline to clean the copper mesh cover, damage should be replaced, and remove dirt from the oil machine to protect the pump and flow meter.
(2) gas station management software and the combination of the pump on the relief valve adjustment screw used to adjust the pump pressure, and then adjust the tanker's oil discharge. Factory has been adjusted. After long-term use, such as the amount of oil dropped, the adjustment screw can be tightened in order to increase the pressure of the pump, but not more than 0.3MPa, so that the amount of oil to meet the requirements.
(3) Combination of pump-type tanker is only suitable for underground tanks, such as the use of high oil tank, there will be exhaust pipe oil phenomenon, then be sure to block the exhaust pipe.
(4) the use of oil guns to avoid the oil gun with the oil pipe percussion by oil containers, press the switch and other abnormal operation, so as not to damage the electronic diesel fuel pump, causing oil spills. To check regularly, tighten the screw on the tubing to prevent the oil pipe root loose, damaged, underground storage tank regularly cleaned to keep the oil clean.
(5) the accuracy of the adjustment of the machine should be "JJG443-86 metering tanker test procedures," the relevant provisions.
(6) overhaul the electrical part of the power must be cut off, should not take electricity repair. Do not damage the explosion-proof surface when opening the explosion-proof case. When the explosion of dust inside the dust should be clean, the cable seal should be good, metal pads, gaskets can not be lost, the number of screws is not missing, tightened to ensure that the electrical components of the explosion-proof performance.

The actual work found in the tanker oil and gas separator common faults are:

First, oil and gas can not be separated
Oil and gas can not be separated from the main performance is the oil in the oil turbidity, a large number of small bubbles in the oil.
There are many reasons for the separation of oil and gas, oil and gas separator flexible pipe below the pipeline, valves, joints in any one lax, may be inhaled gas (pipe is negative pressure), when the amount of gas inhalation beyond the oil and gas separation The ability to separate the gas, it will produce oil and gas can not be separated from the phenomenon.
When there is no separation of oil and gas, first of all to check the tank to the tanker between the oil pipeline is leaking phenomenon, the method is to open the oil and gas separator filter cover, see the oil and gas separator low pressure chamber is oil, if no oil Or oil level slow down, you can initially determine the oil spill. After eliminating the reasons for the pipeline, and then check the oil and gas separator, the simple method is: the tanker in the boot state, with your fingers near the oil and gas separator exhaust pipe, such as the exhaust pipe suction finger, you can determine the cone The valve does not close the oil and gas can not be separated.
Second, the exhaust pipe spit oil
When the tank liquid level higher than the tank calibration software oil and gas separator height, can cause the exhaust pipe to spit oil. Therefore, in the face of exhaust pipe spit oil, the first to see whether the gas station is set up tank, if the elevated tank, the oil and gas separator exhaust pipe can be blocked.
Third, no oil or oil shortage, vibration and noise
Oil filter in the oil separator is too dirty will cause the tanker is not fuel or oil shortage, vibration and noise, and filter cover and very easy to dirty, so the tanker once the above situation, should first consider the cleaning filter Cover, followed by unloading the lower part of the oil valve spring seat, cleaning the oil valve.

Car fuel tank works by moving the equipment to the different equipment and equipment, of course, this is the need to configure, like the tip is essential, no gun can not let the fuel to join the machine equipment, but also Need to be able to move the equipment, so that the tanker can move, when the refueling will be more convenient, but also in space there is no limit, which is the advantages of heavy duty fuel dispenser, but also for a lot of machinery and equipment to provide services, so choose This gas pump filters in the efficiency of the work will be higher, but also in the service will be more high-quality, after all, this is targeted services, so the quality of service will be higher.
Now the product is to be able to facilitate everyone, so in the manufacturing time will be the most convenient way to serve everyone, and car refueling machine is such a product, no matter which area can make this tanker very good The most commonly used is the field diesel engine power refueling, engineering machinery refueling, shipbuilding operations and other equipment can use a variety of equipment, relatively high utilization rate, but also the best way to fill the field of machinery, You can make the work is very convenient to carry out at the same time in the refueling can also provide print services, completely no less than the gas station refueling way, so this tanker in the market is still very popular, the role is irreplaceable.

multi product dispenser is the same function, with the same configuration, the gun can also choose a different, with guns and single guns, through the guns in the cost of the gun will be higher, so the two guns The price will be higher when the sales, of course, the role will be greater, if the car is usually not used guns guns, after all, the high price of guns and the actual role is not great, not very wise Choose, the gun is usually in the large gas station will have, especially the kind of refueling by the customer's own tanker, the most commonly used is the gun, you can save a lot of labor, and when used will be more rapid, So that staff more peace of mind.
china fuel dispenser is the most commonly used a tanker, this tanker will take longer, and will not often fail, save more maintenance costs, so the actual use of the frequency will be higher, The role of the product is great. In the long-term use of the tanker often have to clean, keep the tanker outsourcing clean, not only for everyone to leave a good impression, while the equipment is also a protection, if long-term contamination of the oil will be corrosive Phenomenon, although this corrosion is not very obvious, long-term equipment is also a kind of damage, so cleaning is necessary, regular cleaning will make the equipment better performance.

What are the advantages of a small tanker?

There is no doubt that the volume is very small, so it is more convenient to place and provide different needs, especially in the enterprise is very necessary for such equipment, if the space is very small areas need small equipment for fuel, in the Placed on the more convenient, of course, after use is also easier to clean, the effect will be better in the maintenance, while the small tanker in the transport when also have a great advantage, after all, the small size will be lighter in weight , The damage to mobile devices will be smaller, so the advantages of small retail fuel dispensers products with great, in the actual use of the effect is also very good, to meet the needs of different refueling.
Small tanker in the function is also available, but it also depends on the production of that manufacturer, not every manufacturer of products are high quality, only the big brand products will be more secure, tank gauging equipment Also have such a request, after all, the tanker is only in the power and volume is relatively small, the function is the same, so when the purchase must be very concerned about the function of the problem, to make the product better for everyone, At the same time in the use of the time will be more convenient, the tanker to become the life of the necessary products, we can see that the role is really great, but also has a very strong advantage.

Diesel fuel tanker is the most professional equipment of the vehicle

In the era of high-tech development, each device has high-tech technology, life and work will be more helpful in the release of labor as a slogan today, the use of high-tech technology to allow more labor to liberate, to create More value, so that the economic market development is better, this is the show of high-tech technology, cng fuel dispenser is also the market value, the value of the tanker in the market is high, for many industries to create a great value, as A high-tech technology for human life to raise a high level.
Refueling is a very common behavior in the daily life of the car is the need to refuel, there is no fuel is also very difficult to run, and diesel tanker to meet the needs of refueling, but also to refueling into an industry, and now the gas station is very common , Every gas station has such a gas station dispensers, so that refueling has become very profitable industry, but also to become a service for the public service, so the existence of the tanker is necessary for our lives to solve a lot of problems, But also for the improvement of efficiency in life, in the era of economic development, time is money, is the value of high-tech equipment for life to create a higher value for human life to improve the grade.
In the way of work on the need for transport, save more time, but also to increase the efficiency of the work, such as the means of transport at work or in the hurry are the best tools to become daily life essential help, If there is no fuel such vehicles can not run normally, we will have a great limit on life, so the fuel is the most needed in the transport, and diesel fuel tanker is the most professional refueling equipment, so that more convenient fuel The use of such equipment in life is the most common, but also the most needed equipment, the reason why human is developed, because the more creative, can provide the best help for life and work, which is this Advantages of the equipment.

The price of the tanker can also reflect the function of the product

We have to buy the product when the first concern has always been the price, it seems that prices become the most concerned about the problem, of course, the price had to say is the biggest factor, after all, the price of each product is also a recognition of the product, of course, The product in the market for a recognition, and the tanker price is also the product of the biggest factor recognized, the tanker on the quality requirements are high, if the quality of such products must not be used, when the refueling will appear a lot Of the problem, the impact on the work of great.
There are many kinds of electronic fuel dispenser prices, the more large equipment prices will be higher, of course, technology will be better, in the actual use of the effect is the best, such equipment is often the petrol station favorite, in the professional Of the gas station price is not a big problem, as long as the product can be used more long, the price is not a big problem, the quality is the most important, in the quality of attention when the function is also demanding
