(Switzerland yg series hydraulic cylinder,produced by Hengyu Group）

yg series hydraulic cylinder are widely used in Switzerland，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed yg series hydraulic cylinder for customers from Switzerland.

Introduction to yg series hydraulic cylinder:

The piston seal of the yg series hydraulic cylinder is the main element to prevent leakage in the yg series hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

yg series hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the yg series hydraulic cylinder head itself is the guide sleeve of the piston rod, the yg series hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the yg series hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Do not regularly check the damage of the chrome layer of the yg series hydraulic cylinder: completely extend the yg series 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 yg series hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the yg series hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the yg series hydraulic cylinder.

yg series hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the yg series hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about yg series hydraulic cylinder:

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.
