The installation method of the screw machine rotor shaft sleeve involves a series of detailed and important steps. The following installation method is compiled based on the information in the reference article:

1、 Preparation work

Inspection: Ensure that the rotor, shaft sleeve, and related components (such as stator, sealing ring, etc.) are intact and have no signs of wear or damage.

Cleaning: Clean the interior of the screw pump, especially the rotor, shaft sleeve, and stator, to ensure that their surfaces are clean, oil-free, and in a dry state.

Measurement: Use tools such as micrometers or vernier calipers to measure the gap between the rotor and the shaft sleeve, ensuring that they meet the standard requirements.

2、 Installation steps

Applying lubricating materials: Apply lubricating oil or other suitable lubricating materials to the surface of the rotor to reduce friction between the rotor and the shaft sleeve, and improve the operating efficiency and lifespan of the pump.

Placing the shaft sleeve: Place the shaft sleeve in the correct position on the rotor, ensuring a tight fit and no gap between the shaft sleeve and the rotor.

Installation of rotor: Place the rotor with shaft sleeve into the pump casing, ensuring that the rotor is in the correct position and does not come into contact with the stator.

Install stator: Place the stator into the pump casing, ensuring that the direction of the stator is correctly opposite to the direction of the rotor.

Install pump cover: Place the pump cover on the pump housing and tighten it with bolts to ensure good sealing between the pump cover and the pump housing.

3、 Precautions

Directionality: During the installation process, pay special attention to the directionality of the rotor, shaft sleeve, and stator to ensure their correct fit.

Lubrication: Apply an appropriate amount of lubricating material to the surface of the rotor and shaft sleeve to reduce friction and wear.

Tightness: Ensure that all bolts and other fasteners are tightened to the specified torque or tightening force to ensure the stable operation of the pump.

Inspection: After installation is completed, perform necessary checks such as no-load trial operation to ensure that the pump's operating status meets technical requirements.

4、 Summary

The installation of the rotor shaft sleeve of the screw machine is an important guarantee for the normal operation of the screw pump. During the installation process, it is necessary to carefully inspect each component to ensure that it is intact and undamaged, and follow the correct installation steps and precautions. Only in this way can we ensure the efficient and stable operation of the screw pump.
