Qatar hydraulic cylinder,servo cylinder manufacturer,servo cylinder
(Qatar servo cylinder,produced by Hengyu Hydraulic Co., Ltd）
servo cylinder are widely used in Qatar，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed servo cylinder for customers from Qatar.
When the piston speed of the servo cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the servo cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
When using the servo cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the servo cylinder block. If the servo cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the servo cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the servo cylinder, so that the working efficiency of the servo cylinder is reduced.
The cavitation of the servo cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the servo cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
servo cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the servo cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.
How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
