Two stage rotary vane vacuum pump caused by suddenly turned not is how to return a responsibility?

not long ago, a customer to a small make up message board message called in the application of double rotary vane vacuum pumps, pump caused by suddenly turned not is how to return a responsibility? Small make up today will give everyone explain this problem!

double rotary vane vacuum pump is made of light metal production, and relatively high precision, all the work of the pump are all in contact together, so it's discomfort for containing too much oxygen, harmful, combustible light metal corrosion and oxidation on the vacuum pump oil of various gases, nor as a special refrigeration compressor and pump applications. If the equipment have spirit town of pump, can smoke except for certain condensable gases.

key by double rotary vane vacuum pump pump shell, rotor, vane, bearing end cover, yellow, etc. In the rotary vane pump cavity axial force to install a rotor, and the cylindrical rotor pump cavity surface tangent to the circle ( They have not big gap) And rotor tub armed with yellow two rotary vane, motor stator is separated into two working lumen ( High and low lumen) , turns, double rotary vane vacuum pumps by the centripetal force and yellow support rotary vane at the top of the maintain touch with inner cavity of the pump housing, rotor rotation driven rotary vane drag along the pump cavity chamber, the work of senior lumen capacity expansion regularity and inspiratory, low work lumen capacity regular smaller and smaller gas, rely on the working pressure of gas and oil pull automatic exhaust valve exhaust pipe, vacuum pump is obtained. When the suction pressure is higher, For example, from the beginning of the atmospheric pressure suction) , senior gas in the chamber was narrow, working pressure shock, are part of a miniature gas from auxiliary exhaust valve automatically discharged immediately, another part of the gas after compression according to the wall inside the interstage safe passage into the lower cavity, narrow again after the exhaust valve automatically from the lower row, while high and low, such as cavity exhaust pipe; others When the inlet gas pressure is low, Such as pump work after a period of time) , senior gas of inspiratory mouth into the cavity, the gas in high lumen narrowing caused by work pressure does not immediately pull auxiliary automatic exhaust valve work according to the low level between safe passage into the lumen, again to reduce the exhaust valve automatically from low after discharged. Double rotary vane vacuum pump when you don't turn the unknown can not open pump first, in case of common failures. Hard to plate and can not plate move.

1。 can turn plate moving without root cause the following:

even the axis is common faults; The belt running deviation; The motor wiring is not correct; Motor damage; Without power switch power supply, etc.

2。 Disk or disk can not up too heavy, will cause the following:

1, due to start the pump temperature is too low, the oil viscosity is too high;

2, design manufacture sake stop pump oil too much. Stop caused by high oil pump return oil too much, Give too much oil, or water vapor in the water pump set, or in the exhaust pipe coagulation water back into the pump) ;

3, dirty things inside the pump ( Air inlet of the weld penetration, metal oxide;

4, rotary vane pump such as bomb huang parts of fragments;

5, spiral slice deformation jammed;

6, the teeth bite ( Bushings, rotor, wall, pump cover, motor stator and rolling bearing) 。
