三螺桿泵特點:

1、結(jié)構(gòu)簡單:泵本身僅三根螺桿組成,但有多種結(jié)構(gòu)形成,一般小流量,0.2-6.5m3/h泵的泵體和襯套合為 一個臥式安裝,軸封為機械密封。中等流量以上的泵襯套為一單獨的零件固定于泵體內(nèi)。大流量泵多制成雙吸結(jié)構(gòu)。軸根據(jù)輸送的介質(zhì)不同有端面機械密封和填料密封兩種。船用泵的原動機為交流船用電機。
 2、壽命長:三螺桿泵的主要螺桿是由電動機驅(qū)動。主、從螺桿之間,螺桿與襯套之間皆有一層油膜保護,因泵的機械摩擦極小,壽命堪稱半*性。
 3、所輸?shù)囊后w在泵內(nèi)作軸向勻速直線運動,故壓力脈動小,流量穩(wěn)定,噪音低,由于轉(zhuǎn)動部分慣性小,則起動力矩和振動很小。
 4、具有高吸入能力。
 5、為保證泵、電機及管路系統(tǒng)安全,中等流量以上的螺桿泵均帶有安全閥,當(dāng)壓力超過安全閥設(shè)定壓力時,高壓油將回流至泵的進口。
