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, vacuum pump to stop using, first close the valve, pressure gauge, and then stop the motor.
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 inside 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, after the re-assembly should be trial run, generally required to run for 2 hours and change the oil two times, due to cleaning in the vacuum pump will leave a certain amount of volatile substances, to be normal operation, and then put into normal work.
6, the oil change period according to the actual conditions of use and whether it can meet the performance requirements, etc., 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.
7. 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.
8. Always adjust the packing glands to ensure that the dripping conditions in the packing chamber are normal (in order to make a drip out).
9. Close the gate valve, outlet pressure gauge and import vacuum gauge of the outlet pipe.
10. Move the motor to see if the motor steering is correct.
11. Check the vacuum pump pipe and joints for looseness. Turn the vacuum pump by hand to see if the vacuum pump is flexible.
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. Unscrew the water diversion plug of the pump body of the vacuum pump and infuse diversion (or lead).
15. If abnormal sound is found in the vacuum pump, stop immediately to check the cause.
16. When the vacuum pump is in operation, the bearing temperature must not exceed the ambient temperature 35C, and the maximum temperature must not exceed 80C.
17. In the first month of working, the vacuum pump will be replaced with oil after 100 hours, and after each 500 hours, the oil will be changed once.
18. Conditionally clean up the pipes to ensure that the pipes are open.
19. Regularly inspect the bushings for wear, and replace them when they are worn out.
20. When the vacuum pump is disabled for a long period of time, all the pumps must be disassembled, the water must be wiped dry, and the rotating parts and joints should be greased and stored properly.
21. When the vacuum pump is used during the winter season, after the vehicle is parked, it is necessary to unscrew the screw plug on the lower part of the pump body to release the medium. Prevent freezing cracks.
It can be used in the main body stress structure of the large and medium-size enterprises civil construction, like the plant, warehouse, locomotive shed, hangar, exhibition building, theatre, stadiums, roofing load-bearing load and wall surface support of the arbour.Material of rollers: Shaft Bearing steel(Quenching)

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.
