以吸入式工作的水泵,在启动前必须引水。引水方式通常有两大类;抽真空和向泵壳吸水。管内灌水。这两种类型的引水方式各有其优缺点和相应的适用场合。引水筒引水属于抽真空引水方式,由于其结构简单,引水效果好,但体积较大,故主要适用于小型离心泵的引水系统。《给水排水设计手册》(第9册专用机械)(以下简称“手册9”)第10·2·2节介绍了引水筒的
Pumps that work in suction must divert water before starting. There are usually two major types of water diversion; vacuuming and water absorption into the pump casing. The tube is filled with water. These two types of water diversion methods have their own advantages and disadvantages and corresponding applicable occasions. The water diverting water from the water diversion pipe belongs to the vacuum diversion method. Because of its simple structure and good diversion effect, it has a large volume, so it is mainly applicable to the diversion system of a small centrifugal pump. The water supply and drainage design manual (Section 9 Special Machinery) (hereinafter referred to as “Manual 9”) introduces the water pipe in Sections 10.2 and 2.
