The commonly used speed regulation method of hydraulic station

The commonly used speed regulation methods of hydraulic stations mainly have the following aspects:

1. Throttle speed regulation

This speed regulation method is suitable for both quantitative and quantitative pumps

Execute the components of the hydraulic system.

2. Volume speed regulation

By changing the oil supply of the variable pump or changing the hydraulic pressure

The displacement of the motor to achieve speed regulation.

3. Volume throttle speed regulation

Variable pump oil supply, through the throttle valve or speed regulation

The valve changes the flow into or out of the actuator,

To achieve speed regulation.

The speed control circuit of the hydraulic system should generally meet the following requirements

Basic requirements:

1. It can flexibly realize stepless speed regulation within the maximum and minimum speed range required by the working parts;

2. When the load changes, the adjusted speed will not change, or only change in the allowed range;

3. The power loss should be small to save energy and reduce system heating;

4. Simple structure, safe and reliable
