Relief role and working principle

High pressure relief valve within the tank automation system chamber of a door leading to the low pressure chamber, which is mainly played the role of protection and limit the maximum pressure of the hydraulic system of the hydraulic system, and can adjust the output of tanker traffic. Increased spring force, can increase the maximum pressure of the hydraulic system. Without relief, when the hydraulic system pressure is higher than a certain value. station management system most book weak links will be destroyed.
When the pressure relief valve adjustment screw clockwise twist, the pressure required to open the relief valve increases, most or all of the flow of oil and gas separator. Output increased tanker traffic; when the adjusting screw counterclockwise twist, the pressure required to open the relief valve is reduced, some oil through the relief valve back to the pump suction area, external output flow decreases.

Good protection and safety performance

(1) Fiscal fuel gas station management system is Censtar uses advanced self-styled oil gun, when oil filled container that can automatically turn off the valve inside the gun, cut off the station management system, to avoid oil spills, to ensure clean and safe refueling site .
(2) conducting electrostatic oil hose timely electrostatic refueling vehicle into the ground to prevent electrostatic ignition, to ensure safety.
(3) the use of superior performance cables oil lines, and with hard tube plugs seal suits and other measures to improve the safety performance of the machine

Performance computer tanker

1, measurement accuracy
Under normal circumstances, Censtar computer gas station software per hectolitre error + & - O. Between 3%, after the installation of electromagnetic overcast accuracy can reach i 0.1%.
2, auto zero function
Every mention gun refueling tanker display can instantly return to zero, to overcome the mechanical zero return tanker slow shortcomings.
3, the input data extraction concise
Computer tanker using high quality membrane keyboard, the letter is clear, when the button with voice prompts, to prevent incorrect operation.
4, showing superior performance
(i) display including unit price (yuan / liter), the amount of fuel (liters) Amount ($) three, in a convenient gas station, but also provides for the payment of customers transparency.
(2) quantitative reaction window clearly keyboard input data, quantitative painted refueling operation more convenient.
(3) the windows are made of advanced backlight display, so even at night can be clearly read out various data display.
5, oil filter full
Censtar tax fuel tanker at the inlet and outlet of the oil separator filter are provided (cloth) and a conical strainer, set in the oil gun gun automatic vehicle identification system filter, oil filter makes full, can effectively improve mechanical parts tanker car engine life and protection

Censtar tank

Censtar machine Founded in October 1992, began producing DJ-I, type DJ-II computerfuel management systems, after the mass production of computers tanker CS2000 and Pat production increased every year, more and more varieties, 10 series the popularity of the tanker, 30 series of overhead type tanker, 40 tankers and other large luxury series. In each series, there are a variety of models tanker, as in 10 series, both CS2000-10A universal tanker. There CS2000-10F Gravity 6n oil machine; in the 30 series, there CS2000-30CA single gun tanker, CS2000-30CY guns single oil tanker, CS2000-30CB guns double oil tanker,
CS2000-30CHAJI luxury boutique IC cards and other computer tanker single gun. In 40 series, in addition to guns tanker, there are four guns CS2000-40B4S double oil tanker, C3200040C6S six gun three oil tankers,
CS2000-40Q4 four guns submersible pump dispenser and C52000S-40Q6 six gun submersible pump fuel tanker refueling and other .Censtar tax system expansion ability, can be connected is Star Series management systems and network systems. Fuel tax Censtar computer control and management system has four indoor surveillance vehicle identification system CS

Classification tanker

station management system is the main equipment, which plays the role of a comprehensive oil metering and ensure the safety of oil supply. Many types of tankers, according to count indicates that the device can be divided into mechanical dispensers, electronic and computer refueling tanker three categories.
Mechanical tanker uses mechanical counter, electronic counter electronic tanker instead of the mechanical counter, while increasing the photoelectric sensor, computer tanker is the use of computer-controlled counter. Computer control counter in CPU computer control in addition to completing a simple counting function, but also increased the operation and control functions, pricing function, preset amount of fuel liters or preset functions. In addition, the computer also has a tanker-liter and the total cumulative amount of display and save functions, power-down re-display capabilities, advance and advance shut off valve amount amount into function, and communication with the computer, the computer's other functions accept instruction.
Press each tanker refueling unit, the number of points contained in single and multi-gun gun refueling tanker (guns, four guns, six guns, etc.). In multi-gun tanker, press each tanker can increase the amount of oil into a single tank calibration software, two oil tankers and three oil, four oil, oil tankers and other six.

After the oil flow meter

(1)automated fuel management system along the hose, from, oil gun oil. (2) flow meter operation, transmission signals from the pulse generator
Small tanker card issued by the computer will boot rear ash handling signals to start the motor, and will display the original measurement data back to zero, while the rotation of the motor driven pump, the oil into the oil separator, the oil and gas separation, into meter measurement and through the hose, gun oil to pay for the oil by the oil container. Meanwhile measurement meter back and forth movement of the piston in the process, continue to push the rotation meter rotating elbow. Pivot the elbow again led the rotation measurement sensors, resulting measurement signal fed to the computer, after treatment, after calculation, simultaneous display of the actual amount of fuel in the tanker's sides display.
Small tanker which has an important point: refueling pump is driven by a motor, the petrol station automation system into the oil and gas separator, and then through the oil gun refueling.

 

Precautions tanker safety inspection

A regular check tanker grounding, grounding device to see whether the specification, contact is good.
2, regular testing fuel management systems gun grounding resistance, grounding resistance is ≤10Ω, if abnormal, should be replaced or re-install the hose fittings.
3, regular testing whether internal tanker spill site, if any, should be resolved in a timely manner.
4, periodically check the tanker work sounds unusual, if abnormal, should be promptly excluded, then use.
5, periodically check the internal backup power supply tanker work, if not normal, it is timely maintenance.
6, regular testing tanker measurement accuracy is qualified, if unqualified, should be corrected in a timely manner to find quality inspection departments.
7, regular inspection is complete tanker seals, chip seal is intact, if not complete, it is timely to find the relevant departments or personnel to resolve.
8, regular inspection agency or self-styled refueling emergency stop mechanism is working properly, if not normal, it is timely to exclude or replace the corresponding parts.
9, regular check tanker power lines, power switches, each box is working proof, if normal, should be immediately removed or replaced corresponding parts.
10, regularly check whether the tanker exhaust flow, if unimpeded, could affect measurement accuracy tanker, or endanger the safety of hydraulic pumps and other tank automation system.
