What is the role of the expeller of the slurry pump?

Pumps are now a widely used product in industry. We all know that a very important part of the pump is the impeller, so is it only the impeller that is the most important part of the pump? Use plays an important role?

Maybe we only know that the impeller is the main part of the industrial pump. What we don't know is the role of the expeller. The expeller is also a part that plays an important role in use. So how does this part play an important role? Woolen cloth?

What is the role of the expeller of the slurry pump, then we must first understand what is the expeller of the slurry pump:

The impeller of the slurry pump is an indispensable part of the operation of the slurry pump, and the impeller of the slurry pump also has positive and negative points.

The expeller of the slurry pump is one of the important parts of the slurry pump. It is combined with the pressure reducing cover to form the dynamic seal of the slurry pump, which is one of the three types of shaft seals. Most of the expellers of Panshi Pump are made of high-chromium alloy;

The expeller can play a sealing role and can also reduce the axial force. Under the same performance parameters, if the expeller is installed, the damage of the bearing can also be reduced, and it also plays a role in extending the service life of the bearing;

When the slurry pump is working, the expeller rotates with the main shaft of the slurry pump, and the liquid in the expeller also rotates together, and the rotating liquid will generate an outward centrifugal force, which will reduce the pressure of the medium at the shaft seal to Normal pressure or negative pressure state;

The dynamic seal composed of the expeller and the pressure reducing cover is cost-effective and easy to maintain;

However, the expeller sealing system also has shortcomings. The expeller seal generally needs to cooperate with the parking seal, but the service life of the parking seal is relatively short;

The above is the application of expeller in pumps, as well as the concept, function and knowledge of expeller, which are very important in use. I hope it can be helpful to everyone.
