Fuel dispenser, the full name of motor vehicle fuel dispenser, is for motor vehicles to add fuel measurement system, it includes liquid volume type flow meter, additional device and auxiliary device.
Types of fuel dispenser
The sort of fuel dispenser is very much, can be divided into a few kinds by different means:
According to the display mode is divided into: mechanical display dispenser (mechanical dispenser), electronic display dispenser (computer dispenser);
According to the number of fuel measurement unit is divided into: single-gun dispenser, two-gun dispenser, multi-gun dispenser;
According to the type of power pump is divided into: in-plane pump dispenser and submersible pump dispenser;
According to the dispenser traffic is divided into: ordinary dispenser and high-speed dispenser;
According to the explosion-proof structure is divided into: integrated and isolated explosion-proof type. And so on.
The basic structure of dispenser and the function of main component
The internal pump is mainly composed of oil pump, oil and gas separator, flow meter, motor, oil gun, oil gun switch, solenoid valve, counting sensor, computer device and other parts.
1.Computer device is the dispenser control, operation, count display and data storage center, it through the oil gun switch to get the dispenser starting signal, then through the motor, solenoid valve start dispenser refueling, through the counter sensor to obtain the pulse count signal, flow through the flow meter for the oil count.
2.The oil pump is the power source of the hydraulic system of the oil dispenser. Under the action of the motor, it is responsible for drawing the oil from the oil tank into the oil dispenser and sending it to the oil receiver through the oil and gas separator, flow meter, solenoid valve and oil gun.
3.Oil and gas separator is an important part for oil and gas separator to ensure accurate measurement. It is responsible for oil and gas separation from the oil delivered by the oil pump and discharge the separated gas from the dispenser.
4.Flow meter is the core component of the dispenser for the volume measurement of the oil, it is responsible for the oil sent by the oil separator for the volume measurement, and then through the electromagnetic valve, oil monitor, oil gun into the oil receiver, and the flow meter in the measurement process of a kind of rotation of the mechanical signal transmission to the counting sensor.
5.The counter sensor is a component which converts the mechanical signal of the dispenser flowmeter into the pulse electric signal and replaces it with the encoder in the anti-cheating dispenser.
6.Solenoid valve is the dispenser hydraulic system valve switch, it is composed of two large and small valves, respectively by the dispenser computer control, its application is mainly in order to improve the dispenser quantitative refueling accuracy.
7.Oil gun is a tool for refueling dispenser to fill oil container. It consists of nozzle, valve switch and self-sealing device.
8.Oil gun switch is to start the dispenser refueling electrical control switch, in order to facilitate, generally with the oil gun gun gun mechanism together, after the oil gun extraction, automatically open the start dispenser refueling.
