(Denmark self-locking hydraulic cylinder,produced by Hebei Hengyu company）

self-locking hydraulic cylinder are widely used in Denmark，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed self-locking hydraulic cylinder for customers from Denmark.

Introduction to self-locking hydraulic cylinder:

In recent years, the processing process of the self-locking hydraulic 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.

Before purchasing the self-locking hydraulic cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

The viscosity of the working oil used in the self-locking hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

When purchasing the self-locking hydraulic cylinder, try to clarify the following parameters of the self-locking hydraulic cylinder: A. self-locking hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or self-locking hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right self-locking hydraulic cylinder type can be found accurately and quickly.

Answers to some questions about self-locking hydraulic cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
