[Chemical Knowledge]：Servo valve principle: master the core of high precision hydraulic control technology

Read： 228 Time：13months ago Source：Transform the World with Simplicity

The principle of servo valve is the core of hydraulic control technology, which can control parameters such as flow, pressure and speed to achieve high-precision hydraulic control. Servo valve is a device that can control fluid flow. Its structure is simple, but it has strong control ability. It can achieve extremely high control accuracy in all aspects of flow, pressure and speed. The control principle of the

servo valve is to control the flow rate, pressure and speed by controlling the resistance of the fluid through the flow channel. When the fluid in the servo valve flows through the flow channel, it will produce a certain resistance, which can be used to control parameters such as flow, pressure and speed. The control accuracy of the servo valve mainly depends on the gap size and lubrication between the valve core and the valve seat. When hydraulic pressure acts on the spool, the spool will move in one direction, thereby changing the cross-sectional area of the flow passage, thereby changing the flow, pressure and speed parameters.

servo valve is widely used in industry, metallurgy, aviation, shipping, military, transportation and other fields. In industrial production, servo valves are often used in precision machining, automatic control, pressure control, speed control and so on. In the metallurgical industry, servo valves are often used in casting, forging, extrusion and other processes in the flow, pressure and speed control. In the aviation, marine and military fields, servo valves are often used in hydraulic control systems of aircraft, ships, tanks and other equipment to achieve more precise control. The development of

servo valve has been widely used and promoted. With the progress of science and technology, the control accuracy and application range of servo valve will continue to be improved and expanded. In the future, the servo valve will play a more important role in various fields, bringing more outstanding performance and achievements for people. The principle of

servo valve is the core of hydraulic control technology. Understanding and mastering the principle of servo valve can help people to better carry out high-precision hydraulic control and achieve more accurate flow, pressure and speed control. The control accuracy and application range of servo valve will be continuously improved and expanded in the future.
