Norway hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Norway reset cylinder,produced by Hengyu Hydraulic Cylinder Factory）
reset cylinder are widely used in Norway，because of simple structure and reliable operation，powerful torque，clever hydraulic energy conversion.So our company has designed reset cylinder for customers from Norway.
The coordination of the sliding parts of the reset 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.
When the reset 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 reset 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.
The reset cylinder should be vented: when the reset cylinder is installed or parked for a long time to work again, the air will penetrate into the reset cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the reset cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the reset cylinder, the oil is best entered and discharged from the highest point of the reset cylinder. reset cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
Disassembly reset cylinder: When disassembly reset cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the reset cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the reset cylinder.
When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.
When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.
