Introduction to the core components of fuel dispensers

The core components of fuel dispensers play a crucial role in ensuring their normal operation and accurate measurement. The following is a detailed introduction to the core components of the fuel dispenser:

1. Motherboard
Function: The motherboard is the control center of the fuel dispenser, responsible for processing user inputs, controlling the start and stop of the Fuel pump, measuring fuel volume, and displaying refueling information and other key operations. The motherboard integrates electronic components such as microprocessors, memory, and input/output interfaces, and through interaction with the user interface, achieves comprehensive control over the refueling process.
Importance: Once the motherboard malfunctions, it will affect the normal operation of the entire fuel dispenser, including issues such as users being unable to input fuel information, incorrect fuel volume measurement, and inability to communicate with the gas station management system.
2. Encoder
Function: The encoder is used to record the refueling volume of the fuel dispenser, usually working in conjunction with a Flow meter to convert the mechanical motion of the Flow meter into an electrical signal, which is then transmitted to the motherboard for processing and display.
Importance: The accuracy of the encoder directly affects the measurement accuracy of refueling volume and is an important component to ensure fairness and accuracy in refueling.
3. Monitor
Function: The monitor is used to display refueling information to users, such as oil prices, fuel levels, refueling amounts, etc. It is an important interface for users to interact with fuel dispensers.
Importance: A clear display can ensure that users are informed of the refueling situation in a timely manner, avoiding disputes caused by inaccurate information.
4. Electromagnetic valve
Function: The solenoid valve is a key component in the fuel dispenser that controls the flow of oil. It opens or closes the oil circuit according to the instructions of the main board, achieving precise oil filling.
Importance: The reliability and response speed of solenoid valves directly affect the refueling efficiency and safety of fuel dispensers. Once the solenoid valve malfunctions, it may cause problems such as oil leakage or inaccurate refueling.
5. Oil and gas recovery control board
Function: The oil and gas recovery control board is a newly added component in recent years with the increasing environmental requirements. It is responsible for controlling the operation of the oil and gas recovery system and reducing the emission of oil and gas during refueling.
Importance: The oil and gas recovery control board is of great significance for protecting the environment and reducing air pollution. Through effective oil and gas recovery, the operating costs of gas stations can be reduced and the corporate image can be enhanced.
6. Flow meter
Function: The flowmeter is the core measuring component of the fuel dispenser, used to accurately measure the volume of oil flowing through the dispenser. It usually consists of a measuring transformer and a counting indicator device, which records the flow rate of oil products through mechanical or electronic means.
Importance: The accuracy of the flow meter is directly related to the measurement accuracy and fairness of the fuel dispenser. Regular calibration and verification of flow meters are important measures to ensure accurate measurement of fuel dispensers.
7. Pump
Function: The pump is the power source of the refueling machine, responsible for extracting oil from the storage tank and pressurizing it to transport it to the refueling gun. The performance of the pump directly affects the refueling speed and stability of the refueling machine.
Importance: Regular inspection and maintenance of the pump are crucial for ensuring the normal operation and extending the service life of the fuel dispenser. Meanwhile, the sealing and stability of the pump are also key factors in preventing oil leakage and contamination.
In summary, the core components of a fuel dispenser include a motherboard, encoder, display, solenoid valve, oil and gas recovery control board, flow meter, and pump. The collaborative work of these components ensures the normal operation and accurate measurement of the fuel dispenser. In daily use, maintenance and upkeep of these core components should be strengthened to ensure the long-term stable operation of the fuel dispenser.
