(Bulgaria hydraulic booster cylinder,produced by Hengyu Hydraulic Co., Ltd）

hydraulic booster cylinder are widely used in Bulgaria，because of no need for deceleration device，long service life，smooth movement.So our company has designed hydraulic booster cylinder for customers from Bulgaria.

Introduction to hydraulic booster cylinder:

Because of the slightly complex structure of the buffer hydraulic booster cylinder, sometimes there will be problems, such as when the hydraulic booster cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

The commonly used buffer structure of the hydraulic booster cylinder is composed of a piston boss and a hydraulic booster cylinder head groove. When the piston moves close to the hydraulic booster 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.

When the hydraulic booster cylinder needs to be stored for a period of time, please follow the recommended methods: The hydraulic booster cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the hydraulic booster 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 hydraulic booster cylinder should not be in direct contact with water vapor for a long time. The hydraulic booster cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the hydraulic booster 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 hydraulic booster cylinder Before working, the hydraulic booster cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the hydraulic booster cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

How the cavitation of the hydraulic booster cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the hydraulic booster cylinder, resulting in corrosive damage to the parts.

Answers to some questions about hydraulic booster cylinder:

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
