HSNH940-42具有自吸性能,其運轉(zhuǎn)時吸入性能。由于部件通用化、系列化,有底座式,支架式,浸沒式多種結(jié)構(gòu),可用于臥式,法蘭式和懸臂式安裝。
液體在壓差作用下進入嚙合空間容積。當(dāng)容積增至zui大而形成一個密封腔時,液體就在一個個密封腔內(nèi)連續(xù)地沿軸向移動,直至排出腔一端。這時排出腔一端的螺桿嚙合空間容積逐漸縮小,而將液體排出。三螺桿泵的工作原理與齒輪泵相似,只是在結(jié)構(gòu)上用螺桿取代了齒輪。表為各種螺桿泵的特點和應(yīng)用范圍。三螺桿泵的流量和壓力脈沖很小,噪聲和振動小,有自吸能力,但螺桿加工較困難。泵有單吸式和雙吸式兩種結(jié)構(gòu),但單螺桿泵僅有單吸式。三螺桿泵必須配帶安全閥(單螺桿泵不必配帶),以防止由于某種原因如排出管堵塞使泵的出口壓力超過容許值而損壞泵或原動機。
根據(jù)所輸送介質(zhì)需要還可以提供加熱或冷卻結(jié)構(gòu)形式
用途:可輸送各種不含固體顆粒、無腐蝕性的油類和具有潤滑性質(zhì)的液體。
應(yīng)用:
1、在供熱設(shè)備中用做燃油噴嘴,燃油供應(yīng)和輸送泵。
2、在機械工業(yè)中用做液壓,潤滑和遙控馬達泵。
3、在化學(xué)石油化工和食品工業(yè)中用做裝載、輸送和供液泵。
4、在船舶上用做輸送、增壓、燃油噴射和潤滑油泵以及船用液壓裝置泵。
