Lubricated abrasive wear was found to be the cause of distributor failure. On the basis of selecting reasonably materials and surface strenthening methods of distributors, pump’s function tests under the condition of contamination were performed with actual distributors. The results showed that wear resistance and contaminant wear lifetime of TiN coated high-speed steel W18Cr4V distributor is the best and TiN coating technology can be used in manufacturing of pump’s distributor.展开更多
文摘Several damaged distributors of the shearer’s main pump have been analyzed. Lubricated abrasive wear was found to be the cause of distributor failure. On the basis of selecting reasonably materials and surface strenthening methods of distributors, pump’s function tests under the condition of contamination were performed with actual distributors. The results showed that wear resistance and contaminant wear lifetime of TiN coated high-speed steel W18Cr4V distributor is the best and TiN coating technology can be used in manufacturing of pump’s distributor.
