Several sealing methods of industrial pump factory gravel pump
The application of gravel pump is very extensive, and the medium to be transported is more and more complicated. When we are required to reduce the wear of the gravel pump, the sealing requirements of the gravel pump are very strict. If the sealing performance is not good, many media will leak, resulting in no The necessary loss, so sealing is a very important issue.
First of all, packing seal: it is a kind of ordinary seal. It is injected into the shaft to seal the water. It constantly injects a certain amount of pressure water into the packing to prevent the pump body from leaking out. It is suitable for multi-stage series connection of impeller shaft seal. The pump adopts the packing shaft seal grit pump packing shaft seal structure is simple, the maintenance is convenient, and the price is cheap.we are gravel pump manufacturer and provide dredging single suction cantilever pump,you can know it.

Second, pay the impeller seal:
The impeller force is reversed by a centrifugal force to prevent the external discharge of the slurry. The first stage pump or the multistage pump of the first stage pump can be used as the impeller shaft seal when the positive pressure of the pump inlet is not more than 10% of the pump outlet pressure value. The impeller shaft seal has the advantages of not requiring shaft sealing water, not diluting the slurry, and the sealing effect is good:
Therefore, in the case where dilution is not allowed in the slurry, such a seal can be considered.
Again, mechanical seal:
Generally used in the case of relatively high sealing requirements, especially in the chemical and food fields, not only requires sealing, but also mainly does not allow the addition of additional components into the pump body. The disadvantages of mechanical sealing of the gravel pump are high cost and difficult maintenance.we are gravel pump manufacturer and provide dredging single suction cantilever pump,you can know it.
