is單級(jí)單吸離心泵性能：
is單級(jí)單吸離心泵是根據(jù)標(biāo)準(zhǔn)ISO2858所規(guī)定的性能和尺寸設(shè)計(jì)的，泵為臥式安裝，水平軸向吸入，向上徑向吐出。
主要由(1)泵體 (2)泵蓋 (3)葉輪 (4)泵軸 (5)密封環(huán) (6)軸套 (7)懸架軸承部件等所集成。
is單級(jí)單吸離心泵的泵體和泵蓋的部分，是從葉輪背面處剖分的，即通常所說的后開門結(jié)構(gòu)形式。其優(yōu)點(diǎn)是檢修方便，檢修時(shí)不動(dòng)泵體、吸入管路、排出管路，退出轉(zhuǎn)子部件即可進(jìn)行檢修。 泵的殼體(即泵體和泵蓋)構(gòu)成泵的工作室，葉輪、軸和滾動(dòng)軸承等為軸的轉(zhuǎn)子。懸架軸承部件支承著泵的轉(zhuǎn)子部件、滾動(dòng)軸承承受泵的徑向力和軸向力。泵的軸封采用軟填料密封。軸承為單列向心球軸承，采用潤(rùn)滑油潤(rùn)滑，過流部件材質(zhì)一般為普通灰鑄鐵，用戶若對(duì)材質(zhì)有特殊要求，可與本廠協(xié)商確定。自電動(dòng)機(jī)端看，泵轉(zhuǎn)子均為順時(shí)針方向旋轉(zhuǎn)。
