(Angola supporting cylinder,produced by Hengyu Hydraulic Cylinder Factory）

supporting cylinder are widely used in Angola，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed supporting cylinder for customers from Angola.

Introduction to supporting cylinder:

When the piston speed of the supporting cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the supporting cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The material of the sliding part of the supporting 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.

The commonly used buffer structure of the supporting cylinder is composed of a piston boss and a supporting cylinder head groove. When the piston moves close to the supporting cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

If the supporting cylinder slips or crawls, please check whether there is astringency inside the supporting cylinder, because the internal parts of the supporting cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the supporting cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the supporting cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

Answers to some questions about supporting cylinder:

What is the valve on the hydraulic cylinder?
Oil valve, relief valve, overload valve, explosion-proof valve, etc., these are very convenient to insert! The oil valve, the overload valve and the blasting valve are very important for larger cylinders. Manufacturers will not offer you the selection. You need to choose the values by yourself according to your system, pump, cylinder, environment, working conditions and other comprehensive consideration!

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
