How does the refueling machine control the refueling speed

The main way to control the refueling speed of a fuel dispenser is through its internal flow control system, which integrates key components such as flow sensors, Flow meters, and flow controllers. The following is the specific control process:

1. The function of flow sensors

Function: The flow sensor is a key component in fuel dispensers, used to detect the real-time flow velocity of liquid fuel. It typically uses technologies such as turbine Flow meters, orthogonal helical gear flow meters, or ultrasonic flow meters to accurately measure the velocity and volume of oil flow.

Signal transmission: The flow sensor converts the detected oil flow velocity data into an electrical signal and transmits it to the subsequent flow meter.

2. Processing of flow meters

Function: The flowmeter receives electrical signals from the flow sensor, further processes and calculates the total volume or flow rate of the oil flow.

Data transmission: The flowmeter transmits the calculated flow data to the flow controller.

3. Regulation of flow controller

Function: The flow controller adjusts the speed of oil flow by controlling the opening and closing of the oil pump and valve based on the received flow data and the user's set refueling speed or amount.

Regulation method:

If the user wishes to accelerate the refueling speed, the flow controller will increase the output power of the oil pump or adjust the valve opening to increase the oil flow rate.

On the contrary, if the user wishes to slow down the refueling speed or reach the set refueling amount, the flow controller will reduce the output power of the oil pump or adjust the opening of the valve to reduce the oil flow rate.

4. User interface interaction

Gas dispensers are typically equipped with user interfaces (such as touch screens or buttons) that allow users to input fuel levels, select fuel types, and view real-time information such as refueling speed and volume.

The user interface is connected to the control system of the fuel dispenser, and users can set or adjust the refueling speed through the operations on the interface.

5. Safety and stability considerations

In the process of controlling refueling speed, the refueling machine also considers safety and stability factors. For example, when the fuel tank approaches a full state, the refueling machine will automatically slow down or stop the refueling speed to prevent oil overflow.

In addition, the fuel dispenser also monitors the operating status of the oil pump and valves to ensure their normal operation and avoid malfunctions.

In summary, the fuel dispenser controls the refueling speed through its internal flow control system and user interface interaction. This process involves the collaborative work of flow sensors, flow meters, and flow controllers, as well as considerations of user set refueling parameters and safety stability.
