Vibration and noise caused by valve components

Impurities in the oil block the valve damping hole, the spring in the valve is fatigued or damaged, and too many impurities make the valve core inflexible, which will cause vibration and noise. The valve core and the valve body do not fit well or the surface is roughened. If the fitting clearance is too loose, the internal leakage is serious, and noise and vibration are generated; if it is too tight, the valve core is difficult to...

Causes and solutions for hydraulic creep failure

The actuators of hydraulic equipment often need to move (hydraulic cylinder) or rotate (hydraulic motor) at a very low speed (for example, a few millimeters or even less than 1mm per minute). At this time, there will often be obvious uneven speeds, intermittent movement and stopping, fast and slow, jumping and stopping. This phenomenon is called creeping, that is, the problem of low-speed stability. Creeping is very harmful. For exam...

Working principle of solenoid valve

Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of ...

Why does the valve core of the hydraulic valve stick?

Why does the hydraulic system's spool valve have damping sticking? In a word: contamination! What is damping sticking? It is when tiny particles reside between the hydraulic valve spool and the valve body, increasing the friction of the valve spool movement. Damping sticking reduces the valve's response, affects production, and increases maintenance costs. Normally, the radial clearance between the valve core and the valve bo...

Analysis of the causes of common servo valve failures from static characteristics

Since the servo valve itself is a product that combines electromechanical and hydraulics, and the servo valve and machine equipment form a complex system, when any link fails, how to effectively determine the cause of the failure and propose a solution is very important. There are many ways to analyze servo valve failures. This issue mainly analyzes the static characteristics of the servo valve. We will discuss the failure analysis...
