CWX系列船用卧式自吸离心旋涡泵
概述Overview
CWX系列船用卧式自吸离心旋涡泵，分为有托架和无托架两种。该泵为两级结构：泵盖与外隔板间装有离心工作轮——第一级；外隔板与内隔板间装有漩涡工作轮——第二级。该泵能自吸工作，首次启动前泵体内注满水，由于吸入接管和排除接管的位置均高于泵体，所以泵停车后，保证泵体内的存水，故再次启动就不需要注水便能自吸工作。该泵采用机械密封，密封性能好。该泵具有工作平稳、寿命长的优点。适用于船舶装置抽送饮水、洗涤及卫生用的淡水及海水（T＜85℃）。
Marine horizontal CWX self-priming centrifugal vortex pumps series Marine self-priming centrifugal vortex pumps horizontal, divided into a carrier, and without brackets two kinds. This pump is two-stage structure: with the pump cover with centrifugal work between clapboard wheel - the first level; In between the clapboard and working round with whirlpool partition - 2. The pump can work first self-priming, before starting the pump body filled with water, inhalation and eliminate the takeover takeover position are higher than the pump body, so pump, ensure the pump body after parking is standing, restart wouldn't need water injection can be self-priming work. The pump use of mechanical seal, sealed performance is good. The pump with stable, and a long life and advantages. Applicable to ship device pumping water, washing and health with the freshwater and Marine (T < 85 ℃).
