Belarus hydraulic cylinder,pusher hydraulic cylinder manufacturer,pusher hydraulic cylinder(Belarus pusher hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
pusher hydraulic cylinder are widely used in Belarus,because of long service life,smooth movement,high work efficiency.So our company has designed pusher hydraulic cylinder for customers from Belarus.
When the pusher hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the pusher hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
When the piston speed of the pusher hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the pusher hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
Do not regularly check the damage of the chrome layer of the pusher hydraulic cylinder: completely extend the pusher hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the pusher hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the pusher hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the pusher hydraulic cylinder.
The commonly used buffer structure of the pusher hydraulic cylinder is composed of a piston boss and a pusher hydraulic cylinder head groove. When the piston moves close to the pusher hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.
