                        【問】無密封自吸泵如何提高流量和揚程
                  【答】如何改變無密封自吸泵特性的方法以此來提高水泵的流量和揚程:
                  (1).改變無密封自吸泵的轉速,泵的流量和揚程,均隨無密封自吸泵的轉速變化而變化;
                  (2).改變葉輪直徑葉輪直徑的大小對泵的流量揚程均有影響,所以對葉輪進行切削或更換,葉輪可以改變泵的特性;
                  (3).改變泵的級數;對于無密封自吸泵減少葉輪的數量,即改變葉輪的級數,可以使泵的揚程降低泵耗減小;
                  (4).堵塞葉輪入口的部分通道使泵的流量減小。
