This article mainly introduces:
Nepal hydraulic cylinder,reset cylinder manufacturer,reset cylinder(Nepal reset cylinder,produced by Hengyu Hydraulic Co., Ltd)
reset cylinder are widely used in Nepal,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed reset cylinder for customers from Nepal.
After the reset cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
Causes and countermeasures of oil reset cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the reset cylinder will lead to premature wear of the piston seal, replace the piston seal; If the reset cylinder is visibly scarred, the reset cylinder must be replaced. It can be pressurized at one end of the reset 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 reset cylinder piston drift may not come from the reset cylinder, the above method to determine the reset cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
How to repair the reset cylinder body when it is damaged: When the reset cylinder has trace deformation and shallow tensile marks, the reset cylinder is repaired by strong honing process. The heavy honing process can repair reset cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the reset cylinder can meet the technical requirements.
The reset cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
