( Dry] Use and maintenance of 21 note - vacuum pump

1. Always check the oil level. If do not conform to the requirements, it must be adjusted to meet the requirements. Use the vacuum pump is running, the center of the oil level in oil standard.

2, regularly check the oil quality, found new oil should be replaced in a timely manner to ensure the normal work of the vacuum pump.

3, according to the usage of the user, according to the actual conditions of use and whether to meet the performance requirements to consider oil change period. Usually, when using the new vacuum pump to remove, clean and dry air advice once every 100 hours to replace vacuum pump oil. In oil can't see the black metal powder, can extend the oil change period in the future.

4, under normal circumstances, should check the vacuum pump after running 2000 hours, check the rubber sealing ring aging degree, check whether the exhaust valve parts is broken, and clear the deposition of dirt on the valve and exhaust valve. Seat. Clean the vacuum pump chamber parts, such as rotor, the rotor blades, spring, etc. Usually use gasoline clean and dry. Rubber parts after cleaning, dry with dry cloth. Should be careful when cleaning and assembly.

5, conditionally pipeline cleaning, to ensure that the pipeline flow.

6, after reassembling, should be tested. Normally, it must run 2 hours, and two times an oil change. Because in the process of cleaning will leave a certain amount of hair content in the vacuum pump, so will be able to run normally after normal operation.

7, check if vacuum pump pipe and connector is loose. Turn the vacuum pump with the hand, to see if it is flexible.

8, to add the bearing lubricating oil bearing body. Should pay attention to the oil level in oil mark the centerline. Lubricating oil should be replaced in a timely manner and supplement.

9, unscrewed the vacuum pump of the pump body of water plug screw, and mixed with water, Or slurry) 。

10, close the export pipeline pressure gauge and vacuum gauge entrance gate and exports.

11, the motor running, check motor rotation right.

12, start the motor. When the normal operation of vacuum pump, open the vacuum pump outlet pressure gauge and entry. After pressure display appropriate, gradually open the valve and check the motor load.

13, try to control the circulating water vacuum pump flow and lift, within the scope of the instructions on the label to ensure that the vacuum pump running at peak efficiency, so as to achieve maximum energy saving effect.

14, during the running of the vacuum pump, bearing temperature shall not exceed the ambient temperature 35 ° C, the highest temperature should not exceed 80 ° C.

15, if found abnormal sound vacuum pump, please immediately stop and check the reason.

16, when to stop the vacuum pump, please close the gate valve, pressure gauge, then stop the motor.

17, in the first months after running 100 hours, once every 500 hours to replace vacuum pump.

18, often adjust the packing gland, to ensure that the packing room in the drop of water is normal ( Best for leaks) 。

19, regular inspection of casing wear and tear and wear for replacement.

20。 On a cold winter when using the vacuum pump, after parking, should unscrew the water plug on the lower part of pump body to release medium. To prevent the frost crack.

21, vacuum pump should be discontinued for a long time. Water pump must be completely apart, dry, then daub grease on rotating parts and connectors, and save it in a safe place.
