(Cameroon high pressure cylinder,produced by Hebei Hengyu company）

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

Introduction to high pressure cylinder:

high pressure cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the high pressure cylinder head itself is the guide sleeve of the piston rod, the high pressure 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 high pressure cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Factors that should be considered when selecting the oil seal in the high pressure cylinder: some specific factors should be taken into account when selecting the oil seal in the high pressure cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: high pressure cylinder diameter, piston rod diameter, piston rod and piston groove size, high pressure cylinder working pressure, high pressure cylinder movement speed, hydraulic system oil temperature and high pressure cylinder working environment.

Causes and countermeasures of oil high pressure cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the high pressure cylinder will lead to premature wear of the piston seal, replace the piston seal; If the high pressure cylinder is visibly scarred, the high pressure cylinder must be replaced. It can be pressurized at one end of the high pressure 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 high pressure cylinder piston drift may not come from the high pressure cylinder, the above method to determine the high pressure cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the high pressure cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about high pressure cylinder:

How to remove the lifting cylinder from the forklift truck?
The lifting cylinder is generally fixed on the door frame, and there are screws under and above it, and it is OK to loosen the screws with a wrench on the top. However, we must pay attention to ensure safety and prevent damage to the cylinder or safety accidents.

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
