| 摘 要： | 本文提出描述自吸泵自吸性能的参数是抽气率q和真空度H_s,并且介绍了测试自吸性能的简易方法。文中指出可以自吸性能曲线的斜率K,作为对不同型式自吸泵及其自吸能力强弱的评定值。自吸方式和叶轮圆周速度是影响K值的主要因素。提高自吸泵的自吸性能,就是要提高K的绝对值。

| Abstract: | It is pointed out in this paper that self-priming performance parameters are air pumping rate q and vaccum H,. A simple method to test the self-priming performance is introduced, too. It is shown that the slope K of the self-priming performance curve is the estimation criterion to describe the self-priming ability of different self-priming pumps. Self-priming manner and circumferential velocity of the impeller are the main influence factor on the value of K. Improvement of priming performance means increasing the absolute value of K. |
