(Morocco supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to supporting cylinder:

Under normal circumstances, the supporting cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the supporting cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the supporting cylinder and the end cover, the piston and the piston rod, the piston and the supporting cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the supporting cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The material, shape and compression of the supporting cylinder seal have a great impact on the service life and work efficiency of the supporting cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

When the supporting cylinder needs to be stored for a period of time, please follow the recommended methods: The supporting cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the supporting cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil supporting cylinder should not be in direct contact with water vapor for a long time. The supporting cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the supporting cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the supporting cylinder Before working, the supporting cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the supporting cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

In recent years, the processing process of the supporting cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Answers to some questions about supporting cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.
