In what ways can the speed control of the hydraulic cylinder be achieved?

Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating movement or swinging movement. It is composed of cylinder and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.

The speed control of the device can be achieved in the following ways:

1, throttle regulation: by changing the flow rate of the device to control its speed. Throttle valve has two types of manual regulation and automatic regulation, manual regulation is by rotating the knob to change the size of the throttle valve opening, automatic regulation is by pressure and flow sensors to automatically adjust the size of the throttle valve opening.

2, speed control valve adjustment: speed control valve is a combination of throttle valve and relief valve, by changing the size of the opening of the speed control valve, you can change the flow of hydraulic oil, so as to control the speed of the hydraulic cylinder.

3, proportional valve adjustment: proportional valve is a valve that can adjust the size of the opening in proportion to automatically adjust the flow of hydraulic oil through electrical signals, thus controlling the speed of the device.

4, servo valve adjustment: Servo valve is a high-precision control valve, through the feedback signal to automatically adjust the flow of hydraulic oil, so as to control the speed of the device.

In addition to the above ways, you can also control the speed by changing the displacement of the hydraulic pump and using differential connections. The speed of the hydraulic cylinder depends on the flow rate of the hydraulic oil and the piston area of the hydraulic cylinder, so the control of the speed needs to be adjusted according to the actual situation.
