| 摘 要： | 介绍一种新型离心泵射流自吸装置的工作原理及结构，通过在普通离心泵的进口处增设一个带“文氏管”的自循环射流器，使该射流器与压水室第六断面的回流孔贯通形成自循环，当泵运转时，不仅可以完成自吸过程，而且可以将自循环射流器上的阀关闭，射流器同时停止工作，因此：泵的效率提高了3%以上。泵的性能试验分析表明，该泵不仅可以实现自吸，性能曲线稳定、平坦，高效率区范围宽，工况佳，而且泵的各项技术指标均满足设计要求。

| Abstract: | The principle and structure of a novel jetted self-priming set for the centrifugal pump was introduced.Different from the general centrifugal pumps,a self-circulation jetted set was added in the inlet of this pump,which connects with the reflux hole in the sixth section of the volute,so as to develop the self-circulation.In the process of the pump running,while the self-circulation process can be achieved,the valve of the self-circulation jetted set can be closed.This performance test of the pump demonstrated that the pump could complete the self-circulation process and could operate under the optimum condition.The H~Q curve is stable and flat,and the(efficiency) is 3% higher than that of the conventional centrifugal pumps. |
