Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical chemical methods to pump air from the pumped container to obtain a vacuum. So how much do you know about its maintenance knowledge? Let's follow the editor of Rotary vane vacuum pump semiconductor to have a simple understanding!
1. Check the vacuum pump pipeline and joints for looseness. Turn it by hand to see if it is flexible.
2. Jog the motor to see if the rotation direction of the motor is correct. Do not block the pump outlet.
3. Turn on the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After seeing the proper pressure, open the gate valve gradually to check whether the current and voltage are normal. If there is any abnormality, please stop and check.
4. During operation, the bearing temperature should not exceed the ambient temperature of 35C, and the maximum temperature should not exceed 80C.
5. Need to unscrew the water diversion screw plug of the pump body, and fill the water diversion (or slurry).
6. The gate valve, outlet pressure gauge and inlet vacuum gauge of the water outlet pipeline should be closed.
7. The oil level should be checked frequently. If it does not meet the requirements, it must be adjusted to meet the requirements. When the Vacuum pump is running, the oil level is at the center of the oil standard.
8. The oil quality should be checked frequently. If the oil is found to be deteriorated, it should be replaced with new oil in time to ensure normal operation.
9. Under normal circumstances, the Vacuum pump should be overhauled after 2000 hours of work. Check the aging degree of the rubber seals, check whether the exhaust plate is cracked, and clean up the dirt deposited on the valve plate and exhaust valve seat. Clean the parts in the entire cavity, such as rotors, rotors, springs, etc. It is generally cleaned with gasoline and dried. After cleaning the rubber parts, wipe them with a dry cloth. When cleaning and assembling, handle with care and be careful of injury.
10. Conditionally clean the pipe in the same way to ensure that the pipe is unblocked to achieve the effect of maintenance.
12. After reassembly, a test run should be carried out. Generally, it should be run dry for 2 hours and the oil should be changed twice. Because a certain amount of volatile matter will be left in the Vacuum pump during cleaning, it should be put into normal operation after normal operation.
The above is the editor of Rotary vane vacuum pump semiconductor introducing the maintenance knowledge of Vacuum pump. I hope you can learn more.
