For an ordinary fuel dispenser, it mainly consists of liquid volumetric flowmeter, fuel dispenser pump and assistive devices. According to different working environment, Fuel Dispenser Nozzle can be divided into many types, such as filling station fuel dispensing pump and mechanical display fuel dispensing pump. In order to let you have a preliminary knowledge on fuel dispenser pump and choose a right one, by taking the filling station fuel dispensing pump as an example, we will introduce its basic structures and main applications for you.

In general, filling station fuel dispenser pump is mainly composed of oil pump, oil-gas separator, flow meter, motor, oil gun, solenoid valve, counting sensor, computer device and other components. As we all known, computer device is the control center of operation, count display and data storage for fuel dispenser, which obtains starting signals through the oil gun switch, and then let the dispenser begin to refuel through motor and fuel dispenser solenoid valve. Oil pump is the power source of hydraulic system. Generally, oil pump is responsible for oil suction from Fuel Dispenser Solenoid Valve, and sending it to oil head through oil-gas separator, flow meter, solenoid valve and oil gun under the effect of motor. Oil-gas separator is an important component to guarantee accurate measurement of fuel dispenser, which is responsible for the oil and gas separation of oil sent by oil pump and discharging the separated gas from dispenser.

Under the influence of oil pump, the oil will mix some mixtures when coming into the high pressure chamber. Before these compositions getting into the flow meter, oil and gas separation must be conducted to avoid gases in the oil supplied to users. Flow meter is a core component of volumetric measurement in fuel dispenser, which is responsible for the volumetric measurement of oil sent by oil and gas separator, and then sending oil into oil head through the solenoid valve and oil gun. At the same time, it will transmit the mechanical rotation signals to counting sensor during the process of flow counting.

The role of counting sensor is to change the mechanical rotation signals into electrical pulse signal. Mobile Fuel Dispenser Wholesale is a valve switch of hydraulic system, which mainly consists of large and small valves and fuel dispenser nozzle. These two parts are respectively controlled by fuel dispenser and computer device. The application of solenoid valve is to increase the quantitative accuracy of refuel dispenser. Oil gun is a refueling tool used for oil head. During refueling, when the oil head is full with oil, oil gun can automatically turn off the main and auxiliary valve to prevent oil spill. If the fuel dispenser disrupts to supply oil for oil head, the auxiliary valve is able to close the outlet immediately to prevent the oil continuous flow. As for the oil gun switch, it is an electrical control switch to start refueling process. For convenience, oil gun switch is usually linked with the gun hung component to automatically start the dispenser refueling.
