- The basic working principle of the fuel dispenser
The basic working principle of the fuel dispenser can be expressed as: the pump sucks the fuel from the underground storage tank, divides the gas through the oil-gas separator and then enters the measuring transducer, and removes it through the solenoid valve and the fuel gun. The angular displacement of the output shaft of the measuring transducer is converted into the corresponding electric pulse signal by the sensor, and the cumulative volume of the fuel delivered is displayed by the electronic counting and indicating device.
If it is a mechanical counting type fuel dispenser, the angular displacement of the output shaft of the measuring transducer can be directly displayed by the mechanical counting indicator device to display the fuel volume.
The pump source of the submersible pump dispenser is set in the fuel in the oil storage tank, which can deliver fuel to multiple measuring transducers, and then discharge it through a fuel gun. The counting and indicating device is the same as the fuel dispenser with a pump.
The current home and operation are simple. Remove the oil gun to start the system. Fill the oil tank to automatically close the gun. The rest such as device, unit price adjustment, startup, shutdown, query, and various prompts can be realized by the operating keyboard.
- The main components and functions of the fuel dispenser
Main components and their functions
The fuel dispenser is composed of a pump, an oil-air separator, a flow meter (measuring converter and counting display part), a fuel gun, an electronic system (control, transmission, operation, display), and electrical, pipeline, oil sight, frame cover, etc. constitute.
It is especially necessary to explain that the fuel dispenser is a fuel conveying equipment that works in a flammable and explosive hazardous location. Therefore, the electrical and electronic components and wiring connections of the fuel dispenser must be manufactured and certified in accordance with national explosion-proof standards to ensure product safety.
