Greece hydraulic cylinder,hsgk cylinder manufacturer,hsgk cylinder
(Greece hsgk cylinder,produced by Hebei Hengyu company）
hsgk cylinder are widely used in Greece，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed hsgk cylinder for customers from Greece.
hsgk cylinder buffer valve inspection and maintenance: For the valve buffer hsgk cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
If the seal of the hsgk cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
The quality of the hsgk cylinder can not be ignored in the purchase of the hsgk cylinder. The hsgk cylinder is the main component of the hsgk cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. hsgk cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of hsgk cylinder is deep hole processing, which has always troubled the processing personnel.
The cavitation of the hsgk 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 hsgk 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.
How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
