(2)安装面积小 包含驱动机在内,立式泵只需卧式泵的一半空间就满足了。特别是在泵大型化的今日,这个长处愈加杰出。
一.概述
1.用途:HW混流泵为卧式,单级,单吸,涡壳式混流泵。适用于输送清水或物理,化学性质类似于水的其它液体。被输送液体温度不宜高于50度。广泛用于农田灌溉,工业和城市排水等多种场合。HW泵的性能范围:流量90-9000m3/h 扬程3.5-22m。
2. 特点:结构简单,使用可靠,装修方便,而且效率高,体型小,重量轻。jdhuiquan6.22
3. 传动方式:用直接传动和变速传动。常用动力机是电动机和柴油机。订货 时应明确动力机的型号,以便确定联轴器和皮带轮的型号
4.型号说明:以150HW-8S例
150---------泵进出口直径mm
8------------设计扬程 m
S------------变型代号

(3)有利于防止汽蚀 立式泵的叶轮一般沉没在水中,可以使用的NPSH可以取的大一些。因而,泵运转在比规划点大的流量也不会发作汽蚀。
二.结构和作用
1.HW pump mainly has pump cover, impeller, pump body, pump shaft, bushing, and bearing body and other major components. The pump cover is connected with the pump body and the inlet pipe respectively. 2. There should be an appropriate gap between the pump cover plane and the impeller plane. The gap is too small will produce friction, the gap is too large, will lead to the pump body pressure water a large number of reflux, is the pump efficiency reduction. The suitable gap used in practice is 0.3-0.7mm, and the gap can be adjusted by adding and subtracting the thickness of the paper pad.

应加橡胶垫或石棉线,以防漏气漏水。(4),进水管伸入进水池的位置应合适,进水管口距河底一般为1D—3D,进水管口距枯水面一般为1D—3D,进水管距进水池壁一般为(1—1.5)D(D为进水管口径。2小泵取大值,大泵取小值)。出水口应淹没在出水池的水里,并尽量靠近水面,以减少扬程损失。(6),进水口前应设有网罩,以防水草杂物进入泵内打碎叶轮或堵塞流道。(7),泵装在船上使用并采用润滑油(稀油)润滑时,应考虑到泵在抽上水时引起的船头压低或船身倾侧,必需保证泵轴在运行中保持水平位置,以免轴承因缺油而损坏。(8),650HW型泵采用单列向心推力球轴承,必须保证有适宜的轴向游动间隙,使轴承有良好的承载能力和使用寿命。
3. The shaft is applied to protect the pump shaft and should be replaced in time after wear.
1. Screw holes at the upper end of the pump body, used for filling water diversion or connecting vacuum pump pumping gas to divert water.
2. In order to expand the scope of application of the pump to meet the different needs of users, can cut the outer diameter of the impeller or exchange different performance of the impeller.
