In FAW Jiefang trucks, the role of the oil pump relay cannot be ignored. It ensures the normal operation of the oil pump, protects the safety of the circuit, and realizes the automatic control of the oil pump. It can be said that the oil pump relay is one of the important components to ensure the efficient and safe operation of FAW Jiefang trucks.

In FAW Jiefang trucks, the main functions of the oil pump relay can be summarized as follows:

1. Control the power supply of the oil pump: The oil pump relay controls the on-off control of the oil pump power supply by controlling the contacts of the relay. When the relay receives a start signal, the contacts close and the oil pump starts working; when there is no start signal or a certain protection condition is reached, the contacts open and the oil pump stops working.

2. Protect circuit safety: The oil pump relay has an overload protection function. When the oil pump motor current exceeds the set value, the relay automatically disconnects the contacts to protect the circuit from damage. In addition, it can also prevent the risk of fire caused by short circuits.

3. Realize automatic control: On FAW Jiefang trucks, the oil pump relay is usually connected to the vehicle's control system. According to the vehicle's operating status and needs, the control system will send a corresponding signal to the oil pump relay to automatically start or shut down the oil pump.
