Jordan hydraulic cylinder,hydraulic lifting cylinder manufacturer,hydraulic lifting cylinder
(Jordan hydraulic lifting cylinder,produced by Hebei Hengyu company）
hydraulic lifting cylinder are widely used in Jordan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed hydraulic lifting cylinder for customers from Jordan.
When the piston speed of the hydraulic lifting cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the hydraulic lifting cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
When the oil pressure of the hydraulic lifting cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
The hydraulic lifting cylinder is not the same as the hydraulic lifting cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the hydraulic lifting cylinder can not be used as a high-power power component, but the hydraulic lifting cylinder can be used as a relatively large power component, or the hydraulic lifting cylinder system can be used.
Causes and countermeasures of oil hydraulic lifting cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the hydraulic lifting cylinder will lead to premature wear of the piston seal, replace the piston seal; If the hydraulic lifting cylinder is visibly scarred, the hydraulic lifting cylinder must be replaced. It can be pressurized at one end of the hydraulic lifting cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most hydraulic lifting cylinder piston drift may not come from the hydraulic lifting cylinder, the above method to determine the hydraulic lifting cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.
What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
