Switzerland hydraulic cylinder,pusher hydraulic cylinder manufacturer,pusher hydraulic cylinder(Switzerland pusher hydraulic cylinder,produced by Hebei Hengyu company)
pusher hydraulic cylinder are widely used in Switzerland,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed pusher hydraulic cylinder for customers from Switzerland.
The body of the pusher hydraulic cylinder on the processing process requirements: the body of the pusher hydraulic cylinder is an important and essential part of the pusher hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the pusher hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
There are some honeycomb holes in the inner wall of the pusher hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the pusher hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the pusher hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the pusher hydraulic cylinder is targeted to prevent. Is very necessary.
After the pusher hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
The coordination of the sliding parts of the pusher hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.
