(Qatar limit position hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

limit position hydraulic cylinder are widely used in Qatar，because of long service life，smooth movement，high work efficiency.So our company has designed limit position hydraulic cylinder for customers from Qatar.

Introduction to limit position hydraulic cylinder:

limit position hydraulic cylinder body inspection: The inner surface of the limit position hydraulic cylinder and the piston seal are the main factors causing the leakage in the limit position hydraulic cylinder, if the limit position hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the limit position hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Factors that should be considered when selecting the oil seal in the limit position hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the limit position hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: limit position hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, limit position hydraulic cylinder working pressure, limit position hydraulic cylinder movement speed, hydraulic system oil temperature and limit position hydraulic cylinder working environment.

When the limit position hydraulic cylinder is customized, if there are high requirements for the quality of the limit position hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the limit position hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the limit position hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

limit position hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

Answers to some questions about limit position hydraulic cylinder:

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
