The high temperature of dry vacuum pump and gate valve failure -

high temperature condition of dry vacuum pump

in the process of the application of dry vacuum pump, sometimes there will be a high temperature, high temperature in the short term. However, if the high temperature for a long time, must pay attention to it. Today, I will introduce to you detailed cooling method.

1。 To extend the original cooling fan cover 40 centimeters, reinstall a communion with internal cooling fan diameter of axial flow fan. Axial flow fan motor rated power is 850 w, speed ratio of 14889 r/min, working voltage is 380 volts. Retain the original cooling fan, axial flow fan by other built-in switching power supply mode. Axial flow blower in the dry vacuum pump starts running, and 30 minutes after stop stop axial fan operation, so that the main motor adequate cooling.

2。 Keep dry vacuum pump motor is clean and tidy, clear the stains on the motor in time, increase the ability of heat pipe radiator.

3。 Will be the mother of dry vacuum pump phase voltage to 400 volts.

dry vacuum pump valve failure

dry vacuum pump valve is the key parts. If the vacuum value anomaly shows that gate valves have common faults. The actual performance mainly can refer to the following professional knowledge.

if dry vacuum pump vacuum degree high and low, this problem is more difficult to find, because the main performance is not significant, occasionally appear sometimes. According to working experience, the water pump cavity deformation, mild local accidental damage and leakage, oil seal membrane pump casing jitter problem will make the vacuum value. First dismantle bearing end cover, therefore, to check the concentricity smoothness of the pump chamber, match the size of inner hole, the rack and parallelism, etc.

after the dry vacuum pump assembly line, vacuum degree is still in the fluctuations, doubt pump shell sealing leakage of steam. Therefore, the rubber coating solution is used a few times. After drying, pumping and test. Carefully after listening to the sound of the pump, found that the vibration of the pump shell sound not too clear, a bit uneven. Sometimes, you can see a few bubbles appear, but the water pump shell is still not broken. Through the observation, found no tightly closed vent pump shell. Through inspection, found that the pump shell after installation Angle is not correct, not parallel to the outlet. At this point, the pump shell of the pin is made into a certain Angle, and the water pump shell with elastic shops and tighten. In this way, the vacuum value again is detected, and measuring needle without shaking. Operation prove that it did have been restored.

for dry screw vacuum pump manufacturer of the high temperature condition and dry vacuum pump valve failure, should be check regularly. To prevent a lot of problems.
