1, the repair of the pump body (1) the repair of the pump body crack. Cast 508 nickel-copper welding rod can be used generally, the welding seam after welding requires no porosity, and pump cover surface roughness of the joint surface should not exceed 0.05mm. (2) repair the spindle sleeve bore and driven shaft bore after wear. Drive shaft bushing wear, you can take the method of reaming to eliminate wear traces, and then set with larger size bushing; driven shaft hole wear, the reaming method is often used to eliminate wear marks, and then press the reaming hole The actual size, the preparation of larger diameter diameter driven shaft. (3) Pump housing cavity repair after wear. General approach to repair the cavity set. After the cavity bore large, then set with cast iron or steel inlay. Set in the ring, and then bore the required standard size boring, and put out the end of the ring wear off, so that the decomposition of the pump casing level. (4) Seat repair after wear. Ball valve seat wear, the ball can be used to put a seat on the valve, with a metal bar gently tap the ball several times until the ball valve and valve seat so close. If the valve seat wear more serious, can be controlled first. 2, the pump cover repair (1) pump cover repair work after wear. When the pump cover working surface wear depth of more than 0.1mm, should be repaired. When the working surface of the pump cover is worn less, manual grinding method can be used to eliminate the abrasion marks, and the pump cover is placed on the platform or the thick glass plate. The valve sand is added between the working surface of the pump cover and the surface of the platform for grinding. When the amount of wear larger, there is a serious uneven, should be used after turning polished. (2) active shaft sleeve hole wear repair. Same as the method of repair after the active shaft sleeve hole on the shell is worn.
