(Spain yg series hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

yg series hydraulic cylinder are widely used in Spain，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed yg series hydraulic cylinder for customers from Spain.

Introduction to yg series hydraulic cylinder:

yg series hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the yg series hydraulic cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The material of the sliding part of the yg series hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the yg series hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular yg series hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about yg series hydraulic cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

What is the HS code of the hydraulic cylinder?
HS code of hydraulic cylinder; 8412210000 8412210000 Linear hydraulic power unit (hydraulic cylinder) 0.12000 0.35000 0.00000 0.17000 0.00000
