The main maintenance methods for screw pumps are as follows:
1. **Daily Inspection:** Regularly check the pump's operating status, including temperature, vibration, and noise. If the temperature is too high, vibration is abnormal, or noise is excessive, a malfunction may exist, and the pump should be stopped immediately for troubleshooting.
2. **Lubrication Maintenance:** Add appropriate lubricant to bearings and other parts as specified to ensure good lubrication, reduce wear, and extend service life.
3. **Cleaning:** Keep the screw pump and its surrounding environment clean to prevent debris from entering the pump body and affecting normal operation.
4. **Sealing Inspection:** Inspect the sealing components. If leakage is found, replace the seals promptly to avoid losses caused by media leakage.
5. **Regular Maintenance:** Develop a reasonable maintenance plan, inspect and measure key components such as the screw and bushings, and replace them promptly when wear is severe.
6. **Control Operating Parameters:** Strictly control the pump's flow rate, pressure, and other operating parameters to avoid overpressure and overload operation, which can damage the equipment.
