The rotary vane vacuum pump operates in high temperature to deal with faults

Rotary vane vacuum pump is a device that can generate, maintain and improve vacuum in a certain space through various ways. It is mainly used in chemical, food, electronic and other industries and plays a crucial role in promoting the progress of science and technology and the development of society in China. In the high temperature environment, such harsh conditions, the vacuum pump and other mechanical equipment to the normal and efficient work has brought a severe test.
Vacuum pump high temperature reason:
1. Normal heating, compression heat and friction heat of the motor
2, the power supply voltage is not normal, the motor bus voltage is 380V, due to the cable voltage and uneven load distribution, the motor voltage is less than 380V, the power constant voltage becomes smaller, resulting in current increase, thermal power increase
3, the refrigerant leakage, condensation pressure is too high
4. Low fan speed, small blade and small air volume
5, motor attached to dust and oil, etc., heat dissipation blocked
6, motor performance quality low vacuum pump high temperature solution:
1. Lengthen the fan cover, and install an axial flow fan with the same diameter as the fan inside. The power supply of the fan is also equipped
2. Adjust and control the inlet pressure
3. Dredge and add cooling water
4, adjust the amount of oil, choose high-quality oil
5. Regular inspection, mainly including oil level inspection, temperature inspection, motor load and motor accessories inspection
6. Regular cleaning and maintenance. Keep the motor clean and clean, regularly clean dirt, increase the heat dissipation capacity of vacuum pump motor.
There are many kinds of vacuum pumps, including screw pump, water environmental protection, rotary vane pump, roots pump and vortex pump, etc. According to the types and working conditions of vacuum pump, the influence of high temperature on the normal operation of equipment is analyzed from many aspects. High temperature will not only reduce the working efficiency of the vacuum pump, but also increase the energy consumption. Only by selecting high-quality products and services, keeping an eye on the usual working state of the vacuum pump, and timely maintenance, can the continuous high quality work efficiency be achieved
