1. Check the position of oil level frequently. If it does not meet the requirements, it must be adjusted to meet the requirements. When operating with a vacuum pump, the oil level is subject to the center of the oil standard.
2. Regularly inspect the condition of the oil and discover that the oil should be replaced with new oil in a timely manner to ensure that the vacuum pump is working properly.
3, the oil change period according to the actual conditions of use and whether it can meet the performance requirements, etc., decided by the user's discretion. When a new vacuum pump is generally used to remove clean and dry gas, it is recommended to change the oil once in about 100 hours of operation. After the ferrous metal powder is not visible in the oil, the oil change period can be appropriately extended later.
4. Under normal circumstances, the vacuum pump shall be overhauled after 2000 hours of operation to check the aging degree of the silicone rubber seal, check whether the exhaust valve piece is cracked, and clean the dirt deposited on the valve plate and the exhaust valve seat. Clean the parts of the entire vacuum pump cavity, such as rotors, rotors, springs, etc. It is usually cleaned with gasoline and dried. After cleaning the rubber parts, dry it with a dry cloth. Clean the assembly with care and bruises.
5. Conditionally clean up the pipes to ensure that the pipes are unblocked.
6, after the re-assembly should be trial run, generally required to run 2 hours and change the oil twice, due to cleaning in the vacuum pump will leave a certain amount of volatile matter, to be normal operation, and then into normal work.
7, check the vacuum pump pipe and joints have no loosening phenomenon. Turn the vacuum pump by hand to see if the vacuum pump is flexible.
8. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the centerline of the oil mark. The oil should be replaced or supplemented in time.
9. Unscrew the diversion plug of the pump body of the vacuum pump and infuse diversion (or lead).
10. Close the gate valve, outlet pressure gauge and imported vacuum gauge of the outlet pipe.
11. Move the motor to see if the motor steering is correct.
12. Start the motor. When the vacuum pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After seeing the proper pressure, gradually open the gate valve and check the motor load condition.
13. Try to control the flow rate and lift of the vacuum pump within the range indicated on the label to ensure that the vacuum pump operates at the highest efficiency point in order to obtain maximum energy savings.
14. During the operation of the vacuum pump, the bearing temperature must not exceed the ambient temperature 35C, and the maximum temperature must not exceed 80C.
15. If abnormal sound is found in the vacuum pump, stop immediately to check the cause.
16. When the vacuum pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.
17. In the first month of working, the vacuum pump shall be replaced with oil after 100 hours, and after each 500 hours, oil shall be changed once.
18. Regularly adjust the packing glands to ensure that the drip chambers are in normal condition (in case of drip leakage).
19. Regularly inspect the bushings for wear, and replace them when they are worn out.
20. When the vacuum pump is used during the winter season, after parking, it is necessary to screw the plug of the lower part of the pump body to unscrew the medium. Prevent freezing cracks.
21. When the vacuum pump is deactivated for a long period of time, all the pumps need to be disassembled, the water must be wiped dry, and the rotating parts and joints should be greased and stored properly.
