NBA型冷凝水泵結構型式:
NB、NBA、GN、N型冷凝泵為臥式,GNL為立式。采用滾動軸承,潤滑脂潤滑,軸封為填料密封,也可用機械密封。
NBA型冷凝泵為臥式,前開門結構,即在拆換葉輪時先拆下進水口,擰下聯(lián)軸器螺母,拆下聯(lián)軸器和平鍵,將葉輪和軸從進水口端抽出。
GN型為臥式,固定部分主要由進水段、中段、出水段、軸承體、導葉、密封環(huán)組成。轉動部分的軸向力由球軸承承受,徑向力則由球軸承和裝于導葉上的套筒軸承共同承受。
填料的四周和軸承體上均有冷卻室,可接引冷卻水,進水方向為軸向,出水方向垂直向上,臥式結構輕巧,但需拆卸管路才能檢修。
GNL型為立式,泵體和泵蓋沿軸心線分開,轉動部分的軸向力由球軸承承受,徑向力則由球軸承和套筒軸承共同承受。泵的進水口和出水口均鑄在泵體上,泵體下部有半圓形的泵足,上部則有半圓形支承,支座裝于其上,電機裝在此支座上,立式泵占地面積小,檢修方便。
旋轉方向:從電機端看,泵為逆時針方向旋轉
主要零件材質:泵的體過流部件泵體、泵蓋、密封環(huán)、軸套的材質為鑄鐵,N型冷凝泵葉輪為硅黃銅,誘導輪為鋁鐵青銅。軸均為優(yōu)質碳素鋼。
泵成套范圍:成套供應泵、電機、聯(lián)軸器、止回閥、閘閥。
