1. Repair of the gear pump pump housing cavity After the gear pump casing is worn, it is usually repaired by the inner casing method, that is, after the inner chamber is enlarged, the cast iron or steel bushing is used. After inserting the sleeve, the inner cavity is deflated.
2. Seat repair:
Pressure limiting Valves are available with Ball Valves and plunger valves. After the spherical valve seat wears, place a steel ball on the valve seat, and then tap the steel ball with a metal rod until the ball valve and the valve seat are in close contact. If the valve seat is worn badly, it can be reamed to remove the wear marks and then it can be closed by the upper method. After the piston seat is worn, a small amount of valve sand can be added for grinding until it is tight.
3. Repair of gear oil pump cover Repair of oil pump work surface: If KCB gear oil pump cover wear is small, manual grinding method can be used to eliminate wear marks, ie put a little valve sand on platform or thick glass plate, then pump Cover it and grind it until the wear marks are removed and the work surface is flat. When the wear depth of the working plane of the pump cover exceeds 0.1 mm, it should be repaired by grinding after turning first.
4. Repair gear pump shaft and bush wear repair gear pump drive shaft and bush wear, the increase in the clearance, will affect the pump oil. In this case, the normal fit clearance can be restored by using a drive shaft or bushing. If the wear of the drive shaft is slight, simply press out the old bush and replace it with a standard bush. The clearance can be restored to the allowable range. If the wear of the shaft and the bushing is serious and the clearance is seriously exceeded, not only the bushing must be replaced, but also the drive shaft is chrome plated or vibration surfacing to increase its diameter, and then it is ground to the standard size, and the bushing is restored. The matching requirements.
5. Gear pump oil pump shaft bushing hole and driven shaft hole worn repair tanker gear oil pump shaft bushing hole wear, can be used to eliminate the wear traces after the reaming method, and then with the increase to the appropriate size of the bushing. Driven shaft hole wear is also used to eliminate wear marks by the hinge method, and then the driven shaft is prepared according to the actual size of the reamed hole. 6. The repair of the lubrication oil pump shell The repair of the cracked shell The oil pump shell crack can be cast 508 nickel-copper welding rod Welding repair. Welds must be tight and voids, and the flatness of the joint surface with the pump cover should not exceed 0.05 mm.
