摘要(Abstract):

为保证长周期安全运行,离心泵应在极限工作范围内工作;为求得较高的运行效率,离心泵最好能在优先工作范围内工作。通过分析离心泵的振动限值、温升等来说明如何确定离心泵的工作范围。
Centrifugal pump shall operate in allowable operating region in order to ensure long uninterrupted operating time. Centrifugal Pump is preferred to work in preferred operating region to get high efficiency. By the analysis for vibration limits of pump and temperature rise of the pumped liquid, we can size operating region of centrifugal pumps.

关键词(KeyWords): 离心泵;工作范围;最小连续流量;最大许用流量
