Sweden hydraulic cylinder,cylinder with hydraulic lock manufacturer,cylinder with hydraulic lock

(Sweden cylinder with hydraulic lock,produced by Hebei Hengyu company）

cylinder with hydraulic lock are widely used in Sweden，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed cylinder with hydraulic lock for customers from Sweden.

Introduction to cylinder with hydraulic lock:

The internal leakage of the cylinder with hydraulic lock should be prevented when the cylinder with hydraulic lock is used. The internal leakage of cylinder with hydraulic lock includes the leakage caused by excessive wear of cylinder with hydraulic lock block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

Classification of cylinder with hydraulic lock: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

Most of the failure of the cylinder with hydraulic lock is because there is a foreign body in the cylinder with hydraulic lock into the failure of the cylinder with hydraulic lock, the most problematic is that it is difficult to determine when the foreign body is into the cylinder with hydraulic lock. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

The method of sleeve cylinder with hydraulic lock to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the cylinder with hydraulic lock can be significantly improved by rolling in the finishing of the inner holes of the cylinder with hydraulic lock. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Answers to some questions about cylinder with hydraulic lock:

Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.
