1. Check the oil level position frequently, and adjust it to meet the requirements if it does not meet the requirements. When the vacuum pump is running, the oil level shall be subject to the oil mark center.
2, often check the oil quality, found that the oil deterioration should be timely replacement of new oil, to ensure the normal operation of the vacuum pump.
3. The term of oil change shall be determined by the user at his discretion based on the actual conditions of use and whether the performance requirements can be met. General new vacuum pump, remove clean and dry gas, it is recommended to change the vacuum pump oil for about 100 hours. After the black metal powder is not seen in the oil, the oil change period can be appropriately extended.
4. In general, the vacuum pump shall be overhauled after working for 2000 hours to check the aging degree of rubber seals, check whether the exhaust valve disc is cracked, and clean up the dirt precipitated on the valve disc and exhaust valve seat. Clean the whole vacuum pump chamber parts, such as rotor, rotor, spring, etc. It is usually cleaned with gasoline and dried. Clean the rubber parts and dry with a dry cloth. Handle with care when cleaning and assembling.
5. If possible, clean the pipes to ensure smooth operation.
6. Test operation shall be carried out after reassembly. Generally, it shall run empty for 2 hours and change oil twice.
7. Check whether the vacuum pump pipeline and joint are loose. Turn the vacuum pump by hand to see if it is flexible.
8. Add bearing lubricating oil into the bearing body. Observe the oil level at the center line of the oil mark.
9. Unscrew the water introduction screw plug of the vacuum pump body and pour water introduction (or slurry introduction).
10. Close gate valve of outlet pipeline, outlet pressure gauge and inlet vacuum gauge.
11. Start the motor and check whether the motor steering is correct.
12, start the motor, when the vacuum pump normal operation, open the outlet pressure gauge and the import vacuum pump, as it shows the appropriate pressure, gradually open the gate valve, while checking the motor load.
13, as far as possible to control the circulating water vacuum pump flow and lift within the scope indicated on the label, in order to ensure that the vacuum pump in ****** efficiency point of operation, in order to obtain ****** energy saving effect.
14, vacuum pump in the process of operation, the bearing temperature cannot exceed ambient temperature 35 ℃, * * * * * * temperature shall not exceed 80 ℃.
15. If any abnormal sound is found in the vacuum pump, stop it immediately to check the reason.
16, the vacuum pump to stop using, first close the gate valve, pressure gauge, and then stop the motor.
17, the vacuum pump in the work of ****** months, after 100 hours to change the lubricating oil, after 500 hours, change the oil once.
18, often adjust the packing gland, to ensure that the packing chamber of the drip is normal (into the drip is appropriate).
19. Check the wear of the shaft sleeve regularly, and replace it in time after the wear is large.
20. When the vacuum pump is used in the cold winter, after parking, it is necessary to unscrew the water discharge screw plug at the lower part of the pump body to release the medium. Prevent frost crack.
21. If the vacuum pump is out of service for a long time, it is necessary to disassemble the pump completely, dry the water, coat the rotating part and the joint with grease, and keep it properly.
