Large sleeve on the valve Due to the particularity of the working environment, the use of the sleeve products requires very high reliability and self-lubricating maintenance-free performance, as well as anti-corrosion pollution and other special performance and requirements. According to the different use of the customer environment and requirements, our company chooses different materials to produce mosaic self-lubricating bearings, can significantly improve the reliability and service life of the sleeve products; mosaic self-lubricating bearings mainly choose ZCuAl9Fe4Ni4Mn2 and ZCuPb10Sn10 and other high-performance aluminum Bronze or tin bronze material as the matrix, the surface of solid lubricants, with excellent self-lubricating properties, in the low-speed and heavy load occasions, the use of performance and life is much higher than ordinary tin bronze or aluminum bronze products, and maintenance-free performance And higher use reliability. Widely used in fresh water, sea water, petrochemical, steam and other corrosion and pollution of the environment.
