目前三螺桿泵已在我國(guó)石油、化工、電力、機(jī)床、化纖、冶金、造船等工業(yè)部門(mén)得到較廣泛的應(yīng)用。作為輸送泵、潤(rùn)滑泵、燃油泵和液壓泵,正逐步代替離心泵、齒輪泵和往復(fù)泵。
三螺桿泵的工作原理及其結(jié)構(gòu) 三螺桿泵屬于容積式泵,它主要由主動(dòng)螺桿、與其嚙合的兩根沙動(dòng)螺桿和泵套組成。相互嚙合的一組螺桿按每個(gè)導(dǎo)程形成密封腔,每個(gè)密封腔內(nèi)的液體可看成“液體螺母”,當(dāng)螺桿旋轉(zhuǎn)時(shí),液體自吸入腔一端軸向勻速移到排出腔一端,從而達(dá)到輸送液體的目的。
三螺桿泵的結(jié)構(gòu)大致有兩種,中小流量一般為單吸結(jié)構(gòu)。大流量，低壓一般為雙吸結(jié)構(gòu)。
泵的壓力取決于和它連接的系統(tǒng)總阻力。為了防止由于某種原因使管路阻力突然增加,致使泵壓力超過(guò)允許值而損壞泵、’原動(dòng)機(jī)或管路系統(tǒng),泵必須配帶安全閥或其它過(guò)載保護(hù)裝置。
泵的軸向密封一般采用機(jī)械密封、填料密封和橡膠油封。目前多數(shù)采用機(jī)械密封。
