UAE hydraulic cylinder,hydraulic telescopic cylinder manufacturer,hydraulic telescopic cylinder(UAE hydraulic telescopic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
hydraulic telescopic cylinder are widely used in UAE,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed hydraulic telescopic cylinder for customers from UAE.
The wear of the hard chromium plating layer of the hydraulic telescopic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
hydraulic telescopic 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.
hydraulic telescopic cylinder installation precautions: Before installing the hydraulic telescopic cylinder into the system, the parameters on the hydraulic telescopic cylinder label should be compared with the parameters when ordering. The base of the hydraulic telescopic cylinder must have sufficient stiffness, otherwise the hydraulic telescopic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
The hydraulic telescopic cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.
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.
How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.
