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.
