The working principle of the screw machine rotor shaft sleeve includes the following steps: Lubrication: Lubrication is an important condition for maintaining the normal operation of the rotor shaft sleeve. Lubricating oil can lubricate the shaft sleeve and screw, reduce shaft sleeve wear, and extend service life. If the lubrication is poor or the liquid contains abrasives, it may cause shaft sleeve wear, affecting equipment performance and efficiency

2. Rotation of the rotor: Driven by a motor, the rotor shaft sleeve rotates on the screw, allowing lubricating oil to flow on the screw and completing the oil suction and discharge process

3. Pressure control: By using a pressure regulating valve, the internal pressure of the screw machine can be controlled to maintain it within a certain range, ensuring the quality of the oil and stable pressure

4. Sealing: The screw machine rotor shaft sleeve adopts a sealing device to prevent lubricating oil leakage. Meanwhile, if the shaft sleeve is severely worn, it may be necessary to replace it with a new one and take preventive measures such as strengthening maintenance, improving liquid quality, and operating equipment reasonably

In summary, the working principle of the screw machine rotor shaft sleeve mainly includes four stages: lubrication, rotor rotation, pressure control, and sealing. Only through the coordination and cooperation of these stages can the normal operation and efficient operation of the screw machine be guaranteed
