Ⅱ、一般說明

General DescriPtion

    4、1.5CWX-2/4A型泵是通過帶滾動軸承的鑄鐵托架與驅(qū)動電機聯(lián)接組成，并經(jīng)爪型彈性聯(lián)軸器驅(qū)動；1.5CWX-2/4型泵，由泵體法蘭通過過渡盤與電機法蘭聯(lián)接，泵軸直接套在電機軸上，其轉(zhuǎn)向從電機端看為順時針。

    The centrifugalPumP model  1.5CWX-2/4A  is  driven  through  jaw-tyPe sPring coupling by  drive motor, which is fitted oN  the cast-iron bracket  with ball-bearing. The Pump model 1.5CWX-2/4 is connected by  PumPbody flange through  inter-disc with  motor flange,  in which,the pump shaft is directly insert onto  the shaft of motor and the latter transfers the moment of rotation by lateral  pin and shieldrieg. It's  direction of rotatioe should be clockwise in View of motor side.

    5、泵為兩級結(jié)構(gòu)。泵蓋與外隔板間裝有離心工作輪——第一級；外隔板與內(nèi)隔板間裝有旋渦工作輪-第二級。

    泵能自吸工作，首次啟動前應(yīng)向泵體(1)內(nèi)注滿水，由于泵的吸入接管和排出接管位置均高于泵體，所以泵停車后，保證了泵體腔內(nèi)的存水，故再次啟動就不需注水便能自吸工作。

      The construction of pump is of two-step type.ln whirch, the first step is made of centrifugal workiog wheel, installed between Pump cover and outer diaphragm  Plate Plate, while the second step is
