Metric Hydraulic Cylinders
Product Description
Product Detail
I.Product Introduction
Cylinder is the main component of hydraulic cylinder, single pillar for mining, hydraulic support, gun barrel and so on. Its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, its inner surface roughness requirements are Ra0.4~0.8μm, coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has been puzzling the processing personnel.
II.Fault diagnosis
The piston slips or crawls
Hydraulic cylinder piston slip or creep will make the hydraulic cylinder work unstable. The main reasons are as follows:
(1) Poor lubrication or poor machining of hydraulic cylinder aperture. Because the piston and cylinder, guide rail and piston rod have relative movement, if the lubrication is poor or the hydraulic cylinder aperture is out of tolerance, it will aggravate the wear, so that the cylinder center line linearity is reduced. In this way, when the piston works in the hydraulic cylinder, the friction resistance will be large and small, resulting in slippage or crawling. The elimination method is to repair the hydraulic cylinder, and then according to the requirements of the preparation of the piston, repair the piston rod, configuration guide sleeve.

Production
The hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the cylinder increases by 25%. If only the influence of the cylinder is considered, the service life of the cylinder can be increased by 2-3 times. The efficiency of drilling and rolling process is about 3 times higher than that of grinding process. The above data show that the rolling process is effective and can greatly improve the surface quality of the cylinder.
