三叶罗茨风机排气温度的影响因素分析

Factors Analysis on Affecting Exhaust Temperature of Three Leaves Roots Blower

渐开线叶型三叶罗茨风机的排气温度受到诸多因素的影响,容积效率、内泄漏及工作时的排气压力都能使风机的温升发生变化.实例计算说明,要获得较低排气温度,必须提高风机容积效率,减小内泄漏,采用一定的冷却方法.

The exhaust temperature of three leaves Roots blowers with many factors. Volume efficiency, internal leakage and exhaust pressure will involute leaf shape cause temperature is affected by rise of Roots blowers. With an actual blower as example, the following conclusions are obtained. When Roots blowers work under lower exhaust temperature, high volume efficiency, reducing internal leakage and adopting proper cooling manner are necessary.
