What are the factors affecting the high temperature of Roots blower and the solutions?

The factors affecting the outlet temperature of Roots blower mainly include the following aspects: volume efficiency of Roots blower, working pressure, internal leakage of blower, temperature of suction air. The high temperature of Roots blower is an abnormal phenomenon, which will cause many adverse effects on the blower itself, or even shutdown, thus affecting the work of the whole system.

How to avoid high temperature of Roots blower can be started from the following aspects:

1、 Pipeline: the pressure holding of the pipeline is a factor that is more likely to cause the fan temperature to be too high. According to different diameters of Roots blower, the main pipes at the outlet are fixed. If the diameter of the pipeline with special requirements is changed manually, it is easy to cause pressure holding. In terms of aquaculture, it is often easy to have a thin main pipe, and the modification of the main pipe diameter requires corresponding treatment to ensure the normal outlet pressure of the fan.

2、 Working environment: According to the normal design standard, the fan should be operated in the fan pump room, but most of the Roots fans used by factories and mining enterprises are operated in the open air. In summer, the impact of environmental factors is more obvious. If conditions permit, the site can be equipped with refrigeration and cooling equipment to avoid the impact of environmental factors on the fan as far as possible, or equipped with sound insulation cover with heat dissipation device.

3、 Fan configuration: the pressure and air volume of the fan are certain, but it often happens that small horses pull large cars, that is, small motors with large fans. In this way, in order to meet the flow requirements for use, the fan will cause a relatively large load on the motor, resulting in hot motor and hot fan.

4、 Installation of fan: if the flow pressure of the new Roots fan is normal and not overloaded or hot at the beginning of use, but it starts to burn after a period of time, it means that the fan needs to recheck the tightness of the belt and retighten the fixing screws.
