罗茨鼓风机选型中风量和风压计算方法的探讨
摘要:针对污水处理厂罗茨鼓风机在使用状态与标准状态下,进口温度、压力等条件发生变化时,导致风机的性能也发生变化这种情况,探讨了设计选型时,鼓风机容积流量、出口压力等的确定方法,结合工程热力学原理及罗茨鼓风机的工作原理,推导了流量的计算公式,并通过实际工程中选型设计的计算范例,说明了计算公式的使用方法。

Discussion on Calculation Method of Flow and Pre ssure in Fan Selection for Root s Blower
Abstract :Under the operation and standard con2dition , the performance of Root s blower insewage t reatment plant is changed with inlet tem2perature and pressure , aiming at this problem ,he method to determine volume flow and outlet pressure of blower are discussed. Combining with thermodynamics and the operation principle of blower , the calculation formula of flow is de2 rived , and the using method of the calculation formula is explained through example of selection and design in actual engineering.
