1 改造缘由 秦淮新河抽水站的卧式双向泵装置型式,在80年代初国内所建的双向泵站中,是一种很新颖的装置型式。然而,这种双向泵装置型式至今未能得到推广应用,其根本原因在于叶片调节机构不可靠。秦淮新河抽水站在建成初期叶片调节就很困难,后来由于在调节过程中加大调节力矩,使4~$、5~#水泵叶轮头内蜗杆支座断裂,蜗杆无法支撑,叶片不能自锁固定。1994～1997年水泵大修时分别将1~#、
Rehabilitation reasons Qinhuai River pumping station horizontal bidirectional pump device type, built in the early 80s bidirectional pumping station is a very novel device type. However, the bidirectional pump device type has not been popularized until now. The fundamental reason is that the blade adjusting mechanism is unreliable. Qinhuai Xinhe pumping station in the early stages of the establishment of the blade adjustment is very difficult, and later as the adjustment process to increase the adjustment torque, so that 4 ~ $, 5 ~ # pump impeller worm bearing broken, the worm can not support the blade can not be self-locking fixed. 1994 ~ 1997 pump overhaul were 1 ~ #,
