Use and maintenance of water-cooled vacuum pump

The emergence of vacuum pump has brought good help to manufacturers. With the more and more widely used, it is more suitable for the needs of the public in terms of design and work efficiency. So, what are the use and maintenance methods of water-cooled vacuum pump? Today, Xiaobian will give you a detailed explanation. 1. Check the oil level regularly. If it does not meet the requirements, please adjust it to meet the requirements immediately. In order to avoid damage to the machine due to the oil level not reaching the oil level standard when the vacuum pump is running; 2. Regularly check the oil quality. If the oil is deteriorated, replace it with new oil before the next operation to ensure the normal operation of the vacuum pump; 3. The vacuum pump must be equipped with a vacuum cover to prevent foreign matters from entering the pump; 4. The oil change time of vacuum pump shall be considered according to the actual service conditions and the situation of the machine. Generally, when the new air pump pumps clean and dry gas, it is recommended to change the oil once every 4 days. If the oil quality does not change and there is no ferrous metal powder in it, the oil change period can be extended appropriately; 5. The vacuum pump shall be equipped with a check valve to prevent water from flowing back into the machine when the machine is shut down; 6. Inject water into the water tank every day until the water at the water inlet flows, and inject water regularly every day; 7. Before starting the machine, ensure that the valve is fully opened and the water has been injected into the pump before starting the vacuum pump; 8. Generally, the vacuum pump shall be overhauled after 11 weeks of operation, check the aging degree of rubber, check whether the exhaust valve plate is cracked, clean the precipitated dirt, clean the parts in the vacuum pump, etc. 9. Regularly clean the exhaust port, inhale the atmosphere through the exhaust port to generate vacuum pressure. The length shall not exceed 2m, and the pipeline with a diameter of less than 5cm. If the exhaust port is blocked, the motor will be damaged due to overload; 10. The suction port shall be strictly sealed to avoid air leakage; 11. Close the valve of water pipeline, outlet pressure gauge and inlet vacuum gauge; 12. During the operation of the vacuum pump, the temperature of the bearing shall not exceed the ambient temperature by 35 ℃, and the maximum temperature shall not exceed 80 ℃; 13. When a fault is found during the operation of the vacuum pump and it is necessary to stop, please close the gate valve first, then the pressure gauge, and finally stop the motor; 14. Check and adjust the packing gland frequently to ensure that the leakage inside is normal; 15. Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large; 16. When using the vacuum pump in winter, regularly check the pump to prevent freezing, or add antifreeze; In short, we need to make a specific analysis of the specific situation of the water-cooled vacuum pump, and the above is the most common maintenance knowledge. After reading the article, we will have a better understanding of the causes of the machine failure, and we can accurately find the solution to the problem.
