自吸式离心泵输送粘性液体的性能

根据自吸式离心泵输送水时的自吸性能推导出输送粘性液体时的自吸性能计算公式。试验表明,输送液体的粘度不同,泵的自吸高度和自吸时间也不同。同时,泵的自吸性能还受液体含气量、安装高度和吸入管浸入深度等诸因素的影响,因此应正确地选用和安装。

Performance of self-priming centrifugal pumps while delivering viscous fluid

According to the self-priming performance of a centrifugal pump while delivering water, a formula for calculating its self-priming performance while delivering viscous fluid is derived. Test shows that the self-priming height and period of the pump vary with the viscocity of the fluid delivered and the self-priming performance is also affected by the gas content in fluid, installing height of pump and immersed depth of suction pipe.
