1. Regularly check the oil level to ensure it meets the manufacturer's specifications. If the oil level is too low, top it up immediately. When operating with a vacuum pump, the oil should be at the center of the oil gauge. This helps maintain proper lubrication and prevents damage to internal components. 2. Monitor the oil quality frequently. If the oil appears dark, contaminated, or degraded, replace it as soon as possible. Poor oil quality can lead to increased wear, reduced efficiency, and potential failure of the vacuum pump. 3. The oil change interval depends on usage conditions and performance requirements. For new vacuum pumps used to remove clean and dry gas, it is recommended to change the oil after 100 hours of operation. Once the oil is clear and free from black metal particles, you may extend the oil change interval accordingly. 4. After 2000 hours of operation, perform a comprehensive inspection. Check the condition of rubber seals for signs of aging, inspect the exhaust valve for cracks, and clean any debris from the valve and seat. Clean all internal parts such as rotors, vanes, and springs using gasoline, then dry them thoroughly. When cleaning rubber components, use a dry cloth to avoid moisture retention. Handle all parts carefully during disassembly and reassembly to prevent damage. 5. Periodically clean the piping to ensure there are no blockages. Clogged lines can reduce pump efficiency and cause unnecessary strain on the system. 6. After reassembling the pump, conduct a test run. It is advisable to run the pump for about 2 hours and change the oil twice. This allows any residual volatile substances from cleaning to dissipate before full operation. Once the pump runs smoothly, it can be returned to normal service. 7. Inspect the vacuum pump’s piping and connections for looseness. Manually turn the pump to ensure it rotates smoothly without resistance. A stiff or unusual rotation could indicate mechanical issues. 8. Add lubricating oil to the bearing housing, ensuring the oil level is at the center of the oil mark. Regularly check and replenish or replace the oil as needed to maintain proper bearing function. 9. Remove the water plug from the pump body and drain any accumulated water or slurry. This prevents corrosion and contamination of internal components. 10. Close the gate valve, outlet pressure gauge, and inlet vacuum gauge to prepare for operation. 11. Perform a short motor test to confirm that it is rotating in the correct direction. Incorrect rotation can cause serious damage to the pump. 12. Start the motor. Once the vacuum pump is running smoothly, open the outlet pressure gauge and inlet vacuum gauge. Wait until the pressure readings stabilize, then gradually open the gate valve while monitoring the motor load. 13. Operate the vacuum pump within the flow and lift range specified on the label. Staying within these limits ensures optimal performance and energy efficiency. 14. During operation, monitor the bearing temperature. It should not exceed 35°C above ambient temperature, and the maximum allowable temperature is 80°C. Excessive heat can indicate bearing failure or misalignment. 15. If you hear unusual noises, stop the pump immediately and investigate the cause. Abnormal sounds may signal mechanical failure, misalignment, or worn components. 16. To shut down the pump, first close the gate valve and pressure gauge, then turn off the motor. This prevents backflow and protects the system from pressure surges. 17. In the first month of operation, change the lubricating oil after 100 hours. After that, change the oil every 500 hours to maintain optimal performance. 18. Adjust the packing gland regularly to ensure a controlled drip from the packing chamber. A slight leak is preferable to excessive dryness, which can cause overheating and damage. 19. Check the bushings periodically for wear. Replace them when they show signs of damage to prevent further deterioration of the pump’s performance. 20. In cold weather, after stopping the pump, remove the lower water plug to drain any remaining liquid. This prevents freezing, which can cause cracks and costly repairs. 21. If the vacuum pump will be unused for an extended period, disassemble it completely, clean all parts, and apply grease to moving components and joints. Store the pump in a dry, safe location to protect it from corrosion and damage.
