Relay

How does a relay work?

1. Introduction to excavator relays
Excavator relay refers to a switch with a control circuit, and its basic components are an electromagnetic mechanism and a contact system. In excavators, relays play a very important role and can realize various controls of the circuit system, such as on, off, timing, sequence, etc.
Excavator relays have strong electromagnetic control capabilities and load-carrying capabilities. Its working principle is that the electromagnet attracts the iron core through the action of current, causing the position of the contact to change, thereby achieving circuit control.
2. The function of excavator relay
The main function of the excavator relay is to control the switches of various circuit systems of the excavator. Specifically, excavator relays can help the excavator achieve the following functions:
1. Startup control: The excavator relay plays a vital role in the startup process. It can control the start and stop of the motor and ensure that the power supply is disconnected only after the motor actually stops, thereby ensuring safety.
2. Speed control: The excavator relay can also control the speed of the excavator. Specifically, the excavator relay can control the speed of the motor to ensure the operating efficiency and safety of the excavator.
3. Steering control: The excavator relay can also control the steering of the excavator. The excavator relay receives the signal from the sensor and controls the motor to start or stop, thereby controlling the driving direction of the excavator.
4. Lifting control: The excavator relay can also control the lifting of the excavator. It can control the lifting movement of the high-pressure oil pump, actuator and limiter to complete the lifting operation quickly and accurately.
5. Throttle control: The excavator relay can also control the excavator's throttle. It can receive the driver's operation and control the rotation speed of the motor, thereby controlling the forward speed and operating efficiency of the excavator.
3. Conclusion
The above is the relevant introduction to excavator relays. We can see the importance of excavator relays in excavators. Relays have a very wide range of functions, and their functions are not limited to excavators. They are also used in various other electrical and electronic equipment. How to select, install and maintain relays is the key to ensuring the stable and efficient operation of the excavator circuit system.
