Reasons why the air coming out of the Roots fan is hot
Roots FansIn the process of work out of the gas is hot, so what is the reason for this situation? Roots fan editorial take you to understand.
1、Forced gas transportation
Roots blower in the delivery of gas, the need for forced compression of the fan, fan selection, there is a pressure parameter, such as 39Kpa, Roots blower in the compressed air, the maximum pressure that can withstand 39Kpa, the pressure of the front pipeline reaches 39Kpa, the fan can overcome the pressure of normal operation.
Forced compressed air operation, will inevitably produce heat, so the Roots blower exhaust fan out is with a certain temperature.
2、Inlet temperature
Conveying clean air, the inlet temperature is generally controlled below 40 degrees Celsius, more than 40 degrees Celsius, it is difficult to realize good conveying effect for all aspects of the performance requirements of ordinary fans.
3、Normal fan inlet temperature
If we deliver clean air, the outlet temperature should be kept below 100 degrees Celsius as much as possible, and over 100 degrees Celsius we need to water-cool the tank. If we use a fan with high pressure, we need to use a two-stage tandem-type fan and we need to add a cooler to cool the air.
4, the impact of high temperature on the fan
High temperature on the fan's oil tank, seals, bearings, etc., will have an impact on the serious may lead to the fan can not work, in the daily inspection of the contents of the work, the fan body temperature, bearing temperature, oil tank temperature, need to check, and do a good job of daily record work.
