Roots fan is a forced transmission of gas equipment, because it has forced transmission, so it will inevitably compress the air, the process of compressed air will release a lot of energy, these energy is heat.

Different models of fans, the degree of heating is different, the higher the pressure, the higher the temperature, but the impact of the pressure ratio, under normal circumstances, the temperature rise of about 20 degrees Celsius, why do we actually find that the temperature rise will exceed 20 degrees Celsius?

First of all, the fan may have a certain fault, such as mechanical friction, mechanical friction will further release a certain amount of heat, resulting in a further increase in the exhaust temperature, which may reach more than 110 degrees.

Secondly, pipeline blockage leads to overpressure, which will also increase the release of heat, and overpressure is a more dangerous fault, which is easy to cause the fan motor to burn out. Factors affecting the temperature rise of Roots fan

Then, the influence of the intake temperature, the general fan intake temperature shall not exceed 40 degrees Celsius, the transmission medium is air, in the case of poor heat dissipation, the intake temperature may exceed 40 degrees Celsius, resulting in an increase in the fan outlet temperature.

Too high temperature will affect the parts of the fan, such as: seals, bearings, oil tank oil temperature, etc., which may cause fan failure.

Therefore, in the daily inspection work, the temperature of the fan is also detected, and the temperature of the fan is monitored every day to ensure that the temperature of the fan does not exceed a certain range, so that the Roots blower can be used for a long time.
