Germany self-locking hydraulic cylinder

(Germany self-locking hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

self-locking hydraulic cylinder are widely used in Germany,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed self-locking hydraulic cylinder for customers from Germany.

Introduction to self-locking hydraulic cylinder:

self-locking hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The coordination of the sliding parts of the self-locking hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

The definition of the minimum stable speed refers to the minimum movement speed of the self-locking hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the self-locking hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

In the case of serious wear on the inner surface of the self-locking hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the self-locking hydraulic cylinder manufacturing process for replacement. The self-locking hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

Answers to some questions about self-locking hydraulic cylinder:

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
