Guangzhou Suncar Construction Machinery Co., LTD., founded in 2014, is a foreign trade company specializing in the wholesale and retail of construction machinery seals. Its current business covers many regions at home and abroad.Over the years, we have focused on the innovation and development of manufacturing technology, and have a highly automated production and processing base, providing excavators, bulldozers and other equipment with high-quality sealing parts and accessories, one-stop solution to the maintenance problems of construction machinery.
Loose card always adhere to the "quality to build the core competitiveness, innovation to change the world" business philosophy, vigorously explore overseas markets, develop the science and solid brand strategy planning, on the basis of quality, each type of product made the instruction manual production technology, from raw material selection to each link of manufacturing and processing have strict standards, multilayer testing verifiC.A.Tion, to ensure product quality and performance in accordance with using the standard, size, model can accurately fit the corresponding mechanical equipment, machinery spare parts "made in China" quality feeling and the internationalization of the brand image.
Precautions:
1. Select the appropriate seal material and hydraulic oil, as well as the adaptability to the working temperature and the compatibility of the oil.
2. The geometric position accuracy (concentricity) of the sliding parts relative to the seal is high, the material is good (such as hard chrome plating) and the surface roughness is fine, which can prolong the service life.
(1) For oil seals used in hydraulic pumps and motor journals, it is not only required that the roughness of the sliding surface be within Ra of 0.25m, but also that the surface should be plated with hard chrome, and the oil seal lip should be properly adjusted according to the specific situation during specific use. The radial spring force makes it moderately tight, and a mounting sleeve or a thin gasket should be used to protect the sealing ring during installation to prevent the lip from rolling and twisting, causing the spring to slip out.
(2) The inner surface of the hydraulic cylinder is usually processed by rolling, which not only improves the surface roughness, but also makes the surface hardened by cold work, which is beneficial to prolong the service life of the sealing ring. In addition, the pressure used, the length and type of the sliding surface also have a great influence on the service life. Therefore, the "regular inspection" time should be decided according to these conditions.
(3) The sealing surface is required to be well lubriC.A.Ted to prevent dirt from invading. The use of fluids that meet the specified cleanliness levels and the correct installation method are also necessary conditions.
