In practical application, hydraulic system pollution, leakage, impact, vibration and noise problems, these are the design and use of general power units need to pay attention to several key issues.At the same time these key parameters for the use and operation of the entire hydraulic system will play a great impact.
Hydraulic power unit accessories in the process of power unit operation, if there are more pollutants in the oil, it will lead to the slide valve jam fault between the gap between the slide valve, which will lead to the hydraulic components in the damping hole or throttle hole blockage caused by failure of components and other problems.In fact, about half of the fault problems in hydraulic systems are caused by contamination of hydraulic oil.Therefore, the control of hydraulic oil is very important during production.
In addition to precautions taken to prevent contamination, leakage must be avoided as much as possible.If for some reason the oil exceeds the boundary and flows out of the other tank or system where it should not, it is called a leak.If leakage occurs, it will certainly affect the action of the power unit.While the internal leakage is the leakage from the high-pressure cavity of the components to the low-pressure cavity, the external leakage is the leakage from the components or pipes into the middle flow to the external leakage lifting equipment accessories manufacturers.
At the same time in the process of working hydraulic system, there will be different degrees of impact.This is because during the action of the power unit, there is for some reason a sharp alternating rise and fall in pressure. This damped fluctuation process is called hydraulic impact.Hydraulic impact makes the instantaneous pressure of the system many times larger than the normal pressure. This phenomenon often causes damage and failure of hydraulic components, pipelines and sealing devices, causing system vibration and noise.
Finally, the whole system should be controlled to avoid abnormal vibration or noise.In fact, these two situations are quite common. During the action of the power unit, the vibration is the inherent characteristic of the elastic object, and the noise originates from the vibration. The vibration of the audible noise is called the sound source, so the control of noise is attributed to the control of vibration.
