Slurry Pump Shaft Spacer

Slurry Pump Shaft Spacers Description

The shaft spacer in a slurry pump is a component used to support the pump shaft. It is typically installed on the bearing housing. Its function is to secure the pump shaft, preventing misalignment or wobbling, thereby ensuring stable and efficient pump operation.The structure of a shaft spacer generally consists of the spacer body, spacer cover plate, gasket, bolts, etc., and it exhibits high wear resistance and corrosion resistance.

Pasnto offer all type shaft spacers for  AH, HH, L, M series slurry pumps ,  SP/SPR vertical slurry pumps ,  G/GH gravel dredge pumps ,  AF froth slurry pumps  etc.

Functions & Technical Advantages

The Shaft Spacer is typically installed between the pump shaft and the bearing in a slurry pump. Its main function is to provide an appropriate gap between the pump shaft and bearing, ensuring their proper operation and preventing excessive friction, wear, or heat generation.

Maintain Bearing Clearance

• Technical Advantages:  During installation, the bearing spacer serves as a critical limiting component within the bearing assembly, precisely controlling the axial clearance between the pump shaft and the bearing.
• Performance Enhancement:  Precise clearance is vital for normal bearing operation. It effectively prevents excessive or insufficient bearing preload, avoiding premature failure and abnormal heating. This ensures stable operation throughout the bearing’s design life while significantly reducing vibration and noise during pump operation.

Reduce Axial Force

• Technical Advantages:  During slurry pump operation,  the impeller  and fluid medium generate significant axial thrust. As structural supports within the shaft sealing system, shaft sleeve shims help distribute and transfer portions of this axial force to fixed structures.
• Performance Enhancement:  By ensuring sealing components (e.g., packing rings,  shaft sleeves ) maintain proper axial alignment, it mitigates compression or tension on the sealing system caused by impeller axial movement. This stabilizes the operating environment for seals (packing or mechanical seals), thereby improving sealing performance and reducing leakage caused by axial force fluctuations.

Transmit Torque

• Technical Advantages:  Although the Shaft Spacer is not a primary power transmission component, it plays a critical role in connecting and positioning within the integrity of the entire shaft assembly. It ensures a tight, non-slip connection between the shaft sleeve, impeller, or  bearing assembly .
• Performance Enhancement:  In certain designs, spacers assist in stably transferring torque from the impeller to other shaft components through precise fitment, preventing component loosening or relative rotation. This is vital for maintaining pumping efficiency and structural integrity under high loads.

Prevent Leaks

• Technical Advantages:  The Shaft Spacer serves as the foundational platform for the proper installation and operation of the entire sealing assembly, whether it be a packing seal or a mechanical seal.

1. In packing seals , it precisely positions the stuffing box, ensuring uniform pressure and effective contact between the water seal ring and the packing.
2. In mechanical seals , it ensures the rotating and stationary rings can mate at the correct axial distance, forming an effective sealing interface.

• Performance Enhancement:
  Properly installed shaft spacers minimize axial movement, ensuring the sealing interface or packing remains in optimal working condition. This is crucial for achieving the slurry pump’s “zero leakage” or minimized leakage objectives.

Mateirals

Pasnto Promise:  All Shaft Spacers are precision machined to exacting dimensional tolerances and surface treated (such as Tumble Finish) to eliminate burrs and facilitate installation.
