What are double vacuum pump maintenance - need to be paid attention to

compound is a kind of dry vacuum water pump, vacuum water pump on the reciprocating movement of the piston in the cylinder to the suction and discharge gases. Its main advantage is:

1. High vacuum limit ( 4. 5 - 15 megohm)

2, oil free. Can get a clean vacuum. Is advantageous to the exhaust and solvent cleaning and recycling.

3。 Energy saving, 33%) 。 Save water, 50% r) 。 Save area ( 66%) 。

4。 Air valve of axial alignment. Long service life, 4 - 10 times) 。

5。 Low vibration and low noise.

6。 Simple and beautiful appearance, convenient operation and maintenance.

7。 With no oil structure and tetrafluoroethylene sealing material, can resist all kinds of organic solvents.

8。 Adopt stainless steel material and qin, all kinds of acid, alkali and organic solvent corrosion resistance.

9。 Use of ni-p coating. Can resist various alkali corrosion.

the maintenance and maintenance method of double vacuum pump;

1。 Regularly check the wear condition of shaft sleeve, wear a big change in time.

2。 After parking in the cold of winter, when using, unscrew a discharge plug at the bottom of the pump body, discharge medium. To prevent the frost crack.

3。 Regularly adjust the packing gland, ensure that the packing chamber leak is normal ( Advice in the form of droplets leaks) 。

4。 Long time to stop using the pump will pump completely disassembled, dry water, grease on the components and connectors, and packaged.

5。 Work 100 hours later, the oil change in a month, then once every 500 hours to replace.

6。 If you find any abnormal sound, immediately stop check.

7。 Check whether the reciprocating vacuum pump pipe and connector is loose.

8。 Run, bearing temperature shall not exceed the ambient temperature 35 ℃, high temperature shall not exceed 80 ℃.

9。 Start the motor. When the normal operation of reciprocating vacuum pump, open the outlet pressure gauge and vacuum pump, after being pressure display appropriate, gradually open the gate. At the same time, check the motor load.

10。 Start the motor, and try to see if the reciprocating vacuum pump motor turning right.
