NBA型冷凝水泵结构型式:
NB、NBA、GN、N型冷凝泵为卧式,GNL为立式。采用滚动轴承,润滑脂润滑,轴封为填料密封,也可用机械密封。
NBA型冷凝泵为卧式,前开门结构,即在拆换叶轮时先拆下进水口,拧下联轴器螺母,拆下联轴器和平键,将叶轮和轴从进水口端抽出。
GN型为卧式,固定部分主要由进水段、中段、出水段、轴承体、导叶、密封环组成。转动部分的轴向力由球轴承承受,径向力则由球轴承和装于导叶上的套筒轴承共同承受。
填料的四周和轴承体上均有冷却室,可接引冷却水,进水方向为轴向,出水方向垂直向上,卧式结构轻巧,但需拆卸管路才能检修。
GNL型为立式,泵体和泵盖沿轴心线分开,转动部分的轴向力由球轴承承受,径向力则由球轴承和套筒轴承共同承受。泵的进水口和出水口均铸在泵体上,泵体下部有半圆形的泵足,上部则有半圆形支承,支座装于其上,电机装在此支座上,立式泵占地面积小,检修方便。
旋转方向:从电机端看,泵为逆时针方向旋转
主要零件材质:泵的体过流部件泵体、泵盖、密封环、轴套的材质为铸铁,N型冷凝泵叶轮为硅黄铜,诱导轮为铝铁青铜。轴均为优质碳素钢。
泵成套范围:成套供应泵、电机、联轴器、止回阀、闸阀。
