Analysis of Slurry Pump Seal

The slurry pump seal has always been a problem for researchers to explore hard

With the level of industrial production
Impurity pump use is also expanding
Due to the particularity of the slurry pump delivery fluid
Often where the solid particles are larger
The harmfulness of the liquid is relatively severe
These substances are more common than the ordinary liquid on the shaft and seal corrosion and wear are more serious
Once the seal fails, there will be a leak
Directly affect the normal operation of the pump and pump efficiency Slurry pump seal in the form of three main:

1. The most commonly used seal type is packing seal

The added filler is in full contact with the shaft
To prevent the transmission medium through, so as to achieve the purpose of sealing
This type of seal may cause corrosion of the filler when transporting corrosive material
So the drawbacks of this form of sealing is not able to transport toxic, corrosive liquids

2. Mechanical seal

Mechanical seal is the dynamic ring and static ring by spring in close contact with the axial to achieve the purpose of sealing
Mechanical seal is reliable, almost no leakage
But in the installation should pay attention to protect the friction surface
Avoid wear
The seal is mainly used for conveying flammable and explosive, high temperature and high pressure, strong corrosion of the liquid
Make up for the lack of packing seal

3. Impeller seal

The impeller seal is the impeller force through the reverse centrifugal force
To prevent liquid leakage
Pay the impeller seal without shaft seal water, do not dilute the slurry
This seal can be given priority in the absence of slurry
