    隨著液壓裝置的普及,不僅要求改善作業(yè)人員的環(huán)境,而且像電梯和船用設(shè)備這類與人們居住區(qū)域有關(guān)的場所使用液壓裝置的情況也多起來,所以降低噪聲和振動(dòng)也成為社會(huì)的一大問題.為此,在設(shè)計(jì)液壓裝置時(shí),噪聲小,振動(dòng)小則成為*的條件,這樣采用液壓螺桿泵的機(jī)會(huì)也增多了.
    螺桿泵的結(jié)構(gòu)因螺桿數(shù)不同亦有很大區(qū)別。目前,單螺桿乃至五螺桿泵均能生產(chǎn)。各種螺桿的形狀各不相同,根據(jù)它們的特性可用于不同用途。作液壓裝置用的高壓油泵為三螺桿泵,下面介紹三螺桿泵的結(jié)構(gòu)。
      三螺桿泵的結(jié)構(gòu)
      三螺桿泵基本上是由三根嚙合的螺桿和放置螺桿的襯套構(gòu)成。三螺桿泵有1根主動(dòng)螺桿和2根從動(dòng)螺桿,主動(dòng)螺桿的螺旋槽底徑與從動(dòng)螺桿的外徑相同,螺桿嚙合時(shí)滾動(dòng)接觸.螺旋面的形狀是螺桿橫截面齒形外圓處的尖緣點(diǎn)滾動(dòng)軌跡,設(shè)計(jì)間隙為0.01~0.O5mm,該間隙可根據(jù)螺桿泵的用途進(jìn)行適當(dāng)選擇.
    螺旋面與螺桿襯套之間形成空間,油被封閉在該空間中.主動(dòng)螺桿轉(zhuǎn)動(dòng)時(shí),油從吸入端被送至排出端.該密封腔沿抽向可形成數(shù)個(gè),密封腔內(nèi)的壓力逐級(jí)升高,故油在排出時(shí)壓力不會(huì)發(fā)生急劇變化.又因這些密封腔相互重疊,所以有一定量的油液被排到排出端.從理論上講,排出的這些油量是穩(wěn)定的??蓪?shí)際上,油中含有空氣,以致有可壓縮比,因此排出壓力會(huì)有脈動(dòng),不過該壓力脈動(dòng)值較小,約為排出壓力的2~5%.螺桿泵的噪聲和振動(dòng)都比其它泵小,其噪聲小于10dB(A)。
     螺桿泵與齒輪泵的不同點(diǎn)在于:主動(dòng)螺桿不驅(qū)勸從功螺桿,從動(dòng)螺桿的迥轉(zhuǎn)力來自排出壓力,這就是說,主動(dòng)螺桿不把力傳遞給從動(dòng)螺桿,從動(dòng)螺桿也能迥轉(zhuǎn)。如圖2所示,螺桿泵可以設(shè)計(jì)成圖中(a)和與(a)相反的(b)的情況,但不管哪種場合,螺桿間的接觸力都極小,這就是螺桿泵使用壽命長的原因
