This is how your vacuum pump overload -

some professional knowledge about vacuum pump, small make up believe often applied to its customers for its often have a certain level of understanding, speck vacuum pump manufacturers, must pay close attention to the problem of vacuum pump overload. In the process of operation, because of poor practice will increase the work of electric vacuum pump flow intensity, long after will lead to motor overload, vacuum pump to reduce the gas is directly proportional to the output power and the pressure difference of the need, once the vapour pressure difference is too high, vacuum pump will be overload situation, lead to motor winding ablation. Harm electricity flow has a lot of, the elements of the means of processing and various fusion many years working experience in maintenance. Vacuum pump overhaul manufacturers explore the vacuum pump overload and its matching to avoid because of the countermeasures.

vacuum pump in oil, chemical, plastic, chemical fertilizer, steam turbine dynamic balance equipment, aerospace and interior space simulation device for the long-term operation and therefore should vigorously develop and use in China. Also widely used to crude oil, chemical, metallurgical industry, textile and other industrial production. Vacuum pump parts for to vacuum pump noise processing, vacuum pump exhaust silencer.

under the vacuum pump manufacturers to investigate vacuum pump overload, will have the following categories:

1, vacuum sealing fluid density.

2, is an empty pump sealing liquid temperature is high, the part of the gasification.

3, vacuum pump, vacuum load is high, the exhaust pipe work pressure is too high.

4, vacuum pump water pump seal bad, friction.

5, the problems existing in the motor itself.

6, liposuction material with low viscosity tableland materials, increase the centrifugal impeller and the liquid ring friction.

vacuum pump to reduce the gas is directly proportional to the output power and the pressure difference of the need, once the gas pressure difference is too high, the pump will appear overload situation, lead to motor winding ablation. Handling of pump overload problem to key in any of the following categories:

1, choose vacuum pump electrical components control pump inlet pressure

in the inlet pipe of the vacuum pump according to buy vacuum pump membrane box car relay or electric contact pressure vacuum pressure gauge and other photosensitive resistor. Vacuum pump after startup, when the vacuum pump at the entrance to the working pressure is less than the given value ( Pump allowable starting working pressure) Work, pressure signal light dependent resistor, open the vacuum pump by electrical equipment automatic control system ( As the ultrafiltration device is equipped with a vacuum pump by-pass pipe, the other off bypass valve pipe gate valves) 。 If the pump inlet pressure is higher than standard value, the automatic switch off the vacuum pump ( Or other open pump by-pass pipe gate valves) Run on, then make sure the vacuum pump.

2, selects the pedal fully automatic pressure inlet valve.

inlet valve installed in the pump exit and entry in the middle of the bypass valve on the pipeline. The valve operating pump entrances in the middle of the differential pressure shall not exceed the rated current. When the pressure difference to be rated current, gate on the differential effect automatic open, make the vacuum pump exit and entry, cast a rapid decline in entrance to the middle of the differential pressure, vacuum pump at this time in little differential pressure under the load of work. When the pressure difference is less than rated current, valve automatic turn off, gas according to the front of the vacuum pump by the pump suction walk. Contain a by-pass valve speed regulating valve in front of the vacuum pump to pump the other starting, make the generating set practical simple and convenient operation.

3, selection of hydraulic transmission shafts converter

choose hydraulic transmission shafts converter can also avoid pump overload condition, make the pump can work under high-pressure difference. Hydraulic transmission shafts is installed between the pump and motor. Under the normal working attitude, hydraulic transmission shafts by delivering rating to pump motor end torque. Vacuum pump of the large pressure difference by hydraulic transmission shafts converter transfer bigger torque to decision-making, and the hydraulic transmission shafts converter can send larger torque by the amount of liquid in which to adjust. When the pump work under high-pressure difference or and in front of the pump and started, in the liquid device inside the shaft speed contrast or drag, only transfer torque, the pump speed down. Along with the development of the vacuum, the gas load decreases, vacuum pump speed up slowly to the rating speed ratio.

but may be a problem of the vacuum pump itself, also will be caused by external cause, but the whole process of vacuum pump, dismantling is relatively complex, proposals for technical professional speck vacuum pump manufacturers to carry out a practical communication.
