Sweden trailer hydraulic cylinder

(Sweden trailer hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

trailer hydraulic cylinder are widely used in Sweden,because of no need for deceleration device,long service life,smooth movement.So our company has designed trailer hydraulic cylinder for customers from Sweden.

Introduction to trailer hydraulic cylinder:

There are some honeycomb holes in the inner wall of the trailer hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the trailer hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the trailer hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the trailer hydraulic cylinder is targeted to prevent. Is very necessary.

When the trailer hydraulic cylinder is customized, if there are high requirements for the quality of the trailer 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 trailer 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 trailer hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Improve the service life of the trailer hydraulic cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the trailer hydraulic cylinder (such as the trailer hydraulic cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the trailer hydraulic cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the trailer hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single trailer hydraulic cylinder exhaust.

Under normal circumstances, the trailer hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the trailer hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the trailer hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the trailer hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the trailer hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about trailer 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.

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.
