Rotary vane vacuum pump of high temperature solution - 2 x

a, 2 x rotary vane vacuum pumps, how can appear high temperature?

1, the motor output power is big, work CLP large flow, high temperature vacuum pump.

2, fan impeller number is less, caused by the exhaust air volume is small. Low work speed, air pressure, exhaust air volume is small.

3, vacuum pump motor belongs to the mother phase voltage is 380 v, pressure drop and load dispatch is not well for cable, working voltage motor specific place to add only 369 v, the voltage lower in operating electrical flow.

4, motor with dust, grease, reduce the heat pipe heat dissipation ability to work, resulting in high temperature vacuum pump.

2, 2 x rotary vane vacuum pumps, high temperature solution

the motor output power, rotational speed ratio is and vacuum water pump, you can't change. A cooling fan installed on the motor spindle bearing, motor speed ratio decision work speed, also cannot be moved around. Improve total fan impeller can have certain effect, but the total number of leaves increase, the rotor dynamic balance is not easy to find, such as looking for is not so good, will cause the motor vibration.

1, the original 2 x rotary-vane vacuum pump cooling fan cover 40 cm, refitting a inside diameter of axial flow fan with cooling fan cover, axial flow fan motor output power 850 w, the speed to 1489 r/min, working voltage 380 v. Protect the cooling fan to save again. Axial flow fan control switch power supply all the way up, axial flow fan and the main motor without chain. Vacuum pump starting immediately after starting the axial flow fan operation, vacuum pump stop running 30 min after operation axial flow fan, make its main motor to adequate cooling.

2, remove the dust on the vacuum pump motor, on time to maintain clear electric radiator, promote the heat pipe radiator working ability.

3, the vacuum water pump belongs to the mother phase voltage is 400 v.

everyone understand the vacuum pump oil in the rotary vane vacuum pump plays a crucial effect, very is 2 x rotary-vane vacuum pump, its performance is closely related to the vacuum pump oil, especially the limiting vacuum of vacuum pump working pressure, and the life. Vacuum pump oil is not only as a material for vacuum pump, and the vacuum pump friction lit RunHua, cooling, and sealing effect.

3 and 2 x key performance of rotary vane vacuum pump oil

1, the very low vapour pressure. It is the most important performance of the vacuum pump oil, because of the rotary-vane vacuum pump vacuum value is very high, generally use Shi Laji grease narrow fractions.

2, excellent causticizing stability. Vacuum pump continues to speed development trend, because the sliding vane and the pump shell of the high speed friction makes the oil temperature is high, the product is very easy to oxidation decomposition, especially in the diffusion pump is usually work under high temperature environment, make the system software in vapor pressure rise, vacuum value decreases, and thus rules superior causticizing stability of the vacuum pump oil.

3, suitable viscosity and good viscosity-temperature characteristics. Vacuum pump cavity content exhaust effect resulting from the continuous transformation, prescribed grease should have suitable viscosity and viscosity-temperature characteristics.
