Slurry pump works

Slurry Pump seal there are three ways, each different, the following high-tech tell you these three sealing methods. Slurry pump first packing seal, is the most common type of seal, through the injection of shaft seal water in the constant injection of a certain pressure inside the water, a pump body slurry to prevent leakage: not suitable for use with the Impeller shaft seal Multi-stage series pump, using packing shaft seal. Packing seal structure is simple, easy maintenance, cheap. Slurry pump followed by the impeller seal, through a reverse centrifugal impeller force to prevent slurry leakage. In the pump inlet pressure is not greater than the value of the pump outlet pressure of 10% of the single-stage pump or multi-stage tandem pump of the first pump can be used to pay impeller shaft seal, pay impeller shaft seal without shaft seals, not diluted slurry Body, good sealing effect. Therefore, in the slurry is not allowed to dilute the case, consider such a seal. Again, the mechanical seal, the general requirements of the seal is relatively high use. Especially some chemical, food fields, not only requires sealing, but most importantly does not allow additional ingredients into the pump body. The disadvantage is that the high cost, maintenance difficulties.
