What Is the Function of the Secondary Impeller of the Slurry Pump

1. Efficient auxiliary seal: The secondary impeller can generate reverse pressure during its operation, which can effectively reduce leakage at the shaft seal part. As a result, the sealing effect of the shaft seal is improved and the leakage of the slurry is effectively prevented in the axial direction. This efficient sealing function not only improves the operating stability of the equipment, but also enhances the safety of the equipment, ensuring that the equipment can operate stably under various operating conditions.

2. Axial force balance: The secondary impeller can effectively balance the axial force generated by the impeller during the operation of the slurry pump. This balance effect reduces the axial load on the bearing and thus extends the service life of the bearing. Reducing axial load also means that the maintenance cycle of the bearing is extended, further reducing the maintenance cost of the equipment and improving the operating efficiency of the equipment.

3. Reduce energy consumption: Compared with traditional mechanical seals, secondary impeller seals can reduce energy consumption to a certain extent because of their relatively small friction loss. This means that the equipment can use energy more effectively during operation, reduce energy waste, and thus reduce the operating costs of the equipment.

The secondary impeller of the slurry pump plays an important role in assisting sealing, balancing axial forces and reducing energy consumption. These functions not only improve the operating stability and safety of the equipment, but also help extend the service life of the equipment and reduce operating costs. By using secondary impeller sealing, the slurry pump can achieve efficient and stable operation in various harsh working environments.
