长沙东方工业泵厂，现货直销！

中开泵的主要零件有；泵体、泵盖、叶轮、轴、双吸密封环、轴套等。除轴的材料为优质碳钢外，其余主零件由铸铁、铸钢、不锈钢制成。
﹒泵体与泵盖构成叶轮的工作室，在进出法兰上，装有安装真空表和压力表的管螺孔。进出水法兰的下部，装有放水的管螺纹孔。
﹒经过静平衡检验的叶轮，用轴套和两边的轴套螺母固定在轴上，其轴向位置可通过轴套螺母进行调整。叶轮的轴向力利用其叶片对称布置、两面进水达到平衡。
﹒泵轴承为向心球轴承。轴承装在轴承体内、安装在泵体两端，用黄油润滑。
﹒双吸密封环用以减少水泵压力室的水漏回吸水室。
﹒泵通过弹性联轴器由电动机直接传动，必要时亦可用内燃机传动。
﹒轴封为软填料密封（根据需要也可装机密封）。为了防止空气进入泵内和冷却润滑密封腔，在填料之间装填料环，水泵工作时少量高压水，通过泵盖中开面上的梯形凹槽流入填料腔，起水封作用。
