What Is A Speed Regulator?

The governor is an automatic regulating device that automatically increases or decreases the fuel supply of the injection pump according to the changes in the diesel engine load, so that the diesel engine can run at a stable speed.
Governors have been widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting adjustment, computer power supply heat dissipation, DC fans, etc.
According to its working principle
According to its working principle, it can be divided into mechanical, pneumatic, hydraulic, mechanical pneumatic composite, mechanical hydraulic composite and electronic types. However, the most widely used is the mechanical governor, which has a simple structure, reliable operation and good performance.
The hydraulic governor adds a hydraulic amplifier element (hydraulic servo) between the sensing element and the oil quantity adjustment mechanism, so that the output signal of the sensing element is transmitted to the oil quantity adjustment mechanism through the amplifier element, so it is also called an indirect-acting governor.
The hydraulic amplifier element has both amplification and execution functions, and is mainly composed of two parts: control and execution.
