(S.Africa reset cylinder,produced by Hengyu Hydraulic Cylinder Factory）

reset cylinder are widely used in S.Africa，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed reset cylinder for customers from S.Africa.

Introduction to reset cylinder:

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular reset cylinder action. Troubleshooting method: Replace the rubber hose.

After chrome plating of the piston rod of the reset cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

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

The material of the sliding part of the reset cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Answers to some questions about reset cylinder:

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
