工作压力P: 最高2.5MPa
工作温度T: 最高135°C
S、SH型中开式单级双吸离心泵的主要另件有:泵体、泵盖、叶轮、轴、双吸密封环、轴套、轴承等。除轴的材料为优质碳素钢外, 其馀多为铸铁制成。
S、SH型中开式单级双吸离心泵泵体与泵盖构成叶轮的工作室,在进出水法兰上制有安装真空表和压力表的管螺孔,进出水法兰的下部制有放水的管螺孔。
叶轮经过静平衡校验,用轴套和两侧的轴套螺母固定,其轴向位置可以通过轴套螺母进行调整,叶轮的轴向力利用其叶片的对称布置达到平衡,可能还有一些剩馀轴向力则同轴端的轴承承受。
泵轴由两个单列向心球轴承支承,轴承装在泵体两端的轴承体内,用黄油润滑,双吸密封环用以减少水泵压水室的水漏回吸水室。
水泵通过联轴器由电动机直接传动。
轴封为软填料密封,为了冷却润滑密封腔和防止空气漏入泵内,在填料之间有水封环,水泵工作时小量高压水通过水封管流入填料腔起水封作用。
