Causes of hot air blowing from roots blower

Correct installation Roots blower After the commissioning, why does the Roots blower blow out wind heat? When customers encounter this problem, they usually blame the manufacturer for the problem. They think there may be a problem with the quality of Roots blower. Today, I will take you to understand the cause of hot air blowing from Roots blower.

1. Forced delivery of gas

When Roots blower is conveying gas, it needs to carry out forced compression on the fan. When selecting the fan, there is a pressure parameter, such as 39Kpa. When Roots blower compresses air, the maximum pressure it can withstand is 39Kpa. When the pressure of the front pipe reaches 39Kpa, the fan can overcome the pressure and operate normally. Forced compressed air operation will inevitably generate heat, so the exhaust fan of Roots blower comes out with a certain temperature.

2. Inlet temperature

When delivering clean air, the inlet temperature is generally controlled below 40 ° C and above 40 ° C. It is difficult to achieve good delivery results because of high performance requirements for ordinary fans in all aspects.

3. Inlet temperature of normal fan

If we deliver clean air, the outlet temperature should be kept below 100 ℃ as far as possible. If the temperature exceeds 100 ℃, we need to water cool the oil tank. If we use a fan with high pressure, we need to use a two-stage series fan and install a cooler to cool the air.

4. Influence of high temperature on fan

The high temperature will have an impact on the oil tank, seals, bearings, etc. of the fan, which may seriously cause the fan to fail to work. In the work content of daily inspection, the fan body temperature, bearing temperature, oil tank temperature, all need to be checked and recorded every day.
