特殊条件下水环真空泵的性能研究

Study on Performance of Water Ring Pump Under Special Conditions

生产厂家给出的标准条件下的水环泵性能指标,难以满足特殊工况下设备的使用需求。论述了水环真空泵在出口有反压的条件下泵性能的确定方法,并将理论计算值与实测值进行了比较,两者符合度较好,证明计算精度满足实际应用要求。

The production companies provide the performance specification in a normal working condition. It is difficult to be satisfied with the user＇s requirement in special ones. The computed method of water ring pum＇ s performance was presented under the conditions of counter pressure occurring in vent. The author has compared theoretical calculation values with the measured and the conformity meets the challenge. The result proves that the calculation method has been met practical application.
