215勘探队的几項送水工程,由于揚程較高,如采用离心水泵(揚程90公尺)送水时,必須將整个揚程分为几段,这样就需要較多的設備,同时需要的管理和操作人員也多。另外由于离心水泵的送水量很大,往往只需很短的送水时間就可以滿足要求,故設備利用率亦很低,显然是不合經濟原則的。最近經过該队技术工人的研究,用往复式200/40 215 Several water delivery projects of the exploration team, due to the relatively high lift, must be divided into several sections when the centrifugal pump (head 90 meters) is used to deliver the water. This requires more equipment and requires management and operation. There are many people. In addition, due to the large amount of water delivered by centrifugal pumps, water delivery times can often be met to meet the requirements. Therefore, the utilization rate of equipment is also very low, which is obviously uneconomical. Recently studied by the team’s skilled workers, using a reciprocating 200/40
