Vacuum pump repair flat - how do you know

the using of the vacuum pump the emergence of many common fault problem unrelated areas difficult problem, as this is their internal vacuum pump leakage problems, general situation, what's the part of the vacuum pump is very easy to leak? Also have if appear leakage situation, people should be how to deal with it, deal with before, we have to understand the vacuum pump leakage, therefore, this paper will be made by vacuum pump repair expert team how to know if there is any vacuum pump leakage, leakage and summary the aspects.

vacuum pump is a flat parts are: the weld seam on welding and welding parts, two intersection seam, metal corrugated pipe welding welding parts, 3 joint weld, victims of fitness weld. Flange sealing or dynamic sealing, if carefully clean before installation, assembly line effectively, this kind of parts is not easy to leak. A porcelain, metal materials metal material laminated glass sealing it, such as lead to electricity level, the regulation of high pressure wire, pin, tube caps, etc. The cold and thermal impact damage of weld.

how do you know vacuum pump vacuum pump repair if there is any leakage, summary the following:

1. Intelligent backwater could guide the power of the vacuum pump variable speed centrifugal pump into the condenser, if return water flow is small, can't exhaust valve sealing bag should be centrifugal water pump seal water pressure intelligent backwater to the trench.

2。 Vacuum pump to destroy the door closed, not revealed.

3。 Extraction steam pipe of the vacuum pump is connected to the cylinder can local gas leakage, leakage gas here in load reduce the vacuum pump, vacuum pump after load up slightly higher.

4。 Condenser water vapor side door closed, don't say.

5。 In air pressure conditions at the bottom of the piezoelectric water heater can everything is normal, can put the trench gate are inseparable.

6。 Vacuum pump control system of liquid level meter is distorted and discuss.

7。 Vacuum pump control system the exhaust valve gate valve, pipe, flanges, or weld there is inseparable, especially up big box or start separation equipment to the condenser pipe heating furnace and the gate mouth.

8。 The bottom of the vacuum pump pressure cylinder exhaust steam security doors.

vacuum pump repair manufacturer instructions, the general vacuum pump leak is caused by the following conditions.

1) Vacuum pump seal doesn't close tightly, twist all the link anchor bolt, tightened filling material screw cap, and firmly to package ChanGuan road and dashboard areas connected to other artifacts. Or changing a gasket, filling material. For gas leaks, will also be able to apply oil as temporary protection measures such as lime powder.

2) Rolling bearing tilt: this kind of situation make obliquely in centrifugal impeller in the pump housing. Effect for the single pump, the radial gap is not symmetrical, Ye Yan turns, must also have part of the friction and side cover, graze my side cover and centrifugal impeller inner hole, extend the radial gap. Narrow cavity when gas according to expand the space, many leaked to absorb into the cavity, reduce vacuum values or exhaust pressure of work. This time you need to rolling bearing to carry out maintenance, then to carry out the installation properly.

3) Before and after the left and right side cover different heart: will the vacuum pump before and after the left and right side cover have a lot of is not parallel, bad influence and also tilt of the rolling element bearing.

4) Hot vacuum pump, vacuum pump temperature rises, the saturation vapor pressure also with the rise, it will reduce the vacuum value, but it is no harm to the exhaust pipe work pressure.
