Rotary-vane vacuum pump are used to pay more attention to what problem? - - - - - -

rotary-vane vacuum water pump are the key by the pump shell, rotor, vane, bearing end cover, yellow, etc. In rotary vane vacuum pump cavity axial force to install a rotor, the rotor inner hole and pump cavity surface tangent to the circle ( They have not big gap) , the rotor tub comes with two rotary vane yellow. When the rotor rotating rotary-vane can drag along its axial groove reciprocating and touch and the cavity in the pump body from beginning to end, the rotary vane with rotor rotation, the vacuum pump cavity can be divided into several variability capacity. So in the actual operation of the rotary-vane vacuum pump should pay attention to what problem? We look together!

1, the application of rotary vane vacuum water pump, ensure the pump clean, avoid dirt into the pump. Query of oil, in order to stop the pump when the drops of oil to oil gauge management center is advisable. Too low for automatic exhaust valve can not be oil sealing effect, vacuum value. Too high, can cause air start pump. When running, the rise in oil has certain belongs to normal condition. Oil select request types of cleaning, vacuum pump oil from the oil inlet added. After the oil supply, should be spinning oil plug. Oil should be after, in case of dirt into the block oil inlet, add oil according to the oil gauge marked scale vacuum pump oil. Turn the three way valve, make the pump suction pipe and air exchange, and were cut off time vessels, open the outlet.

2, working at high temperature, oil temperature rise, lower viscosity, saturation vapour pressure will expand, can cause has certain lower limit vacuum pump, very of the gas pressure is measured with thermocouple.

3, rotary vane vacuum pump is not used to smoke in addition to the high oxygen content, flammability and erosion to metal material with gas. In addition, also not suitable for suction reflects with the pump oil into gas and gas with a lot of water vapor, etc.

4, rotary vane vacuum pumps can be in all through the air or vacuum values starting next time, relay water pump such as loading, should with the pump and the actual operation.

5, rotary vane vacuum pump running after all normal, slowly turn the three way valve, make the pump suction pipe and the time of vessel cut off each other and with the air.

6, forcibly rotating pulley, check the operation condition, no abnormal phenomenon, and access to the switch power supply, pay attention to rotating bearing.

7, after a period of time, relaxation of belt is more and more, to carry out the regulation of motor parts. Pay attention to fill the oil pump, found that the pump oil is stained with dirt or water, is changing a new oil, high pressure cleaning pump body, prohibit using ethyl formate height, toluene and other volatile liquid high pressure cleaning pump body.

8, examine the limiting vacuum of vacuum pump on the basis of narrow type liquid silver vacuum gauge, such as the meter by adequate drainage efficacy, achieve smooth pump temperature, pump inlet and immediate access, running three within ten minutes, will be limit vacuum pump.

9, such as air humidity is higher, or by extraction contains more condensable vapors, access is pumped vessels, after appropriate open gas ballast valve, fitness 20 ~ 40 minutes later turn off the gas ballast valve. Stop before the pump, valve can KaiQi town full fitness 3 ten minutes, in order to increase the service life of the pump oil.

10 and stop using rotary vane vacuum pump, to maintain the ultrafiltration device has the certain vacuum value, should turn the three way valve, make the ultrafiltration device enclosed, pump suction pipe and air exchange. Disconnect switch power supply, terminate the operation. Turn off the air outlet, cover tightly pump cover.
