pump shell meaning in English
泵壳
Examples
- Based on the technical requirements of manufacture , application and repair of the pump shell and cutter piece of the cutterhead pipeline dredge , put forward are the re - manufacture three principles on easily damaged workpieces of dredge engineering . with the inter - clamped structures on the pump liners , the gradient wear - resisting design on the cutter piece , and the new techniques in the process of re - manufacture , new wear - resistant materials , including high - cr alloy , overlaying and brazing deposits , and polymer adhesive coatings have been successfully applied to the re - manufacture dredge pump shell and cutter piece . the application results show that their wear - resistant lifetimes and the dredging profits have been increased remarkably
