How to extend the life of heat-insulated gear pump

Insulation gear pumps often have the following failures during use. We hope that users will pay attention to their use and ensure that they can play an important role and value in their use. They can play an important role in the industry.

Insulation gear pumps are used in accordance with a certain method and principle in use to ensure that they can exhibit good functions and values ​​in a certain industry. Normal maintenance and maintenance are required in daily use, and they can show important in the industry field. Performance and value. Insulation gear pumps often have certain faults in use, and are well maintained and repaired when faults occur, guaranteeing that they can produce important performance and value in the aspects.

1. The shaft bushing hole and driven shaft should not be greater than 0. Repair of hole wear: After the shaft bushing holes are worn, the reamed bushes can be used. The wear of the driven shaft hole is also eliminated by the reaming method. Then the driven shaft is prepared according to the actual size of the reamed hole. The crack of the shell can be welded by welding the 508 nickel-copper alloy welding rod. Welds must be tight and voids, with the insulation gear method to eliminate wear marks, and then used to increase the flatness error of the combined size of the corresponding size pump cover 05mm.

2. Seat repair: There are two types of pressure limiting valve: ball valve and plunger valve. The ball bar gently taps the ball until the ball valve and 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 heat-insulating gear pump cover: Repair of work plane: If the work surface of the pump cover wears little, use hand, that is, put a little valve sand on the platform or thick glass plate, and then remove the wear marks from the pump cover by grinding method. Grind it until the wear marks are removed and the work surface is flat. When the surface wear depth exceeds 0.1 millimeters, when the pump cover is working in meters, it should be repaired by first turning and grinding.

4. Repair of the inner cavity of the heat-insulating gear pump casing: After the inner cavity of the heat-insulating gear pump casing is worn out, a large-size rear-mounted casing is equipped with cast iron or steel liner. After inserting the sleeve, the inner cavity will be repaired using the inner cavity insert method, that is, the inner cavity.
