                  (1)故障原因:

                 ?、倭⑹诫x心泵內產生汽蝕,由于氣泡在高壓區突然破裂,氣泡周圍的液體急劇向空間靠攏,產生水擊。

                 ?、谟捎谕蝗煌k?,造成系統壓力波動。

                 ?、塾捎谕蝗煌k姼邏阂褐该偷构?,沖擊泵出口單流閥閥板。

                 ?、鼙贸隹诠苈返拈y門關閉過快,產生沖擊。

                  (2)排除方法:

                 ?、俑纳票玫纳纤畻l件,減少或杜絕汽蝕發生。

                 ?、诓扇∫欢ù胧?,減少系統壓力波動。

                 ?、蹖?strong>立式離心泵不合理排出系統的管路及管路附近的布置進行改造。

                 ?、荜P閉閥門時要緩慢,避免過快。
