Hydraulic cylinder corrosion prevention capacity is high, driven by the hydraulic cylinder used in the service life of the hydraulic system, zhejiang hydraulic parts manufacturers in the process of operation has a certain quality mechanism, when the hydraulic cylinder moved to the end of the stroke, in the process of operation, has a large kinetic energy.If there is no deceleration treatment, the domestic screw insert valve manufacturers will be the cylinder piston and cylinder head mechanical collision, can produce the impact to some extent.
Threaded cartridge valve manufacturers of strong corrosion resistance and service life
The corrosion resistance and service life noise of the hydraulic cylinder are destructive. In the process of making the hydraulic cylinder, its processing quality directly affects the service life and reliability of the product. The cylinder has high processing requirements, and the internal surface roughness Ra is 0.4.0.8um, coaxiality of the abrasion resistance is strict?The basic characteristic of cylinder cylinder is the deep hole processing, the high pressure thread insert valve factory its processing causes the processing personnel to be distressed?The adoption of a certain degree of hydraulic cylinder block processing, in the process of manufacturing in the surface residual stress, surface residual stress of zhejiang hydraulic parts price to a certain extent, help to closed surface tiny cracks, due to the expansion of the layer to a certain degree of inhibition of erosion, thus can improve the surface corrosion prevention ability, can delay the generation of fatigue crack and expanded, so that can improve the surface corrosion prevention ability, can delay the generation of fatigue cracks and expand.Can improve the degree of cylinder bore fatigue strength.
Through a certain degree of roll forming, when operating the hydraulic cylinder, the surface of the roller can directly form a cold hardening layer. Domestic screw insert valve manufacturers can reduce the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the cylinder and avoiding grinding burn.The wound.The decrease of surface roughness after roller can increase preparation.Performance.
When the hydraulic cylinder walks, ningbo semen pressure fluid passes through the roller after the product's hole surface roughness in front of the roller Ra3.On the TAB page, select the background TAB page, and select the background from 3 microns to Ra0.4-0.Reduced to 8um, the surface hardness of the hole was increased by about 100%, and the surface fatigue strength in the cylinder cylinder was increased by 2% and 5%.Considering the influence of the cylinder, the life of the cylinder is increased by 2.3 times, and the efficiency of the grinding rolling technology is improved by about 3 times compared with the grinding technology.The above data show that the roller process can significantly improve the surface of the cylinder.
