SNH66R51U12.1W2螺桿油泵結構
隨著液壓裝置的普及,不僅要求改善作業人員的環境,而且像電梯和船用設備這類與人們居住區域有關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也成為社會的一大問題.為此,在設計液壓裝置時,噪聲小,振動小則成為*的條件,這樣采用液壓螺桿泵的機會也增多了.
螺桿泵的結構因螺桿數不同亦有很大區別。目前,單螺桿乃至五螺桿泵均能生產。各種螺桿的形狀各不相同,根據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構。
三螺桿泵的結構
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成。三螺桿泵有1根主動螺桿和2根從動螺桿,主動螺桿的螺旋槽底徑與從動螺桿的外徑相同,螺桿嚙合時滾動接觸.螺旋面的形狀是螺桿橫截面齒形外圓處的尖緣點滾動軌跡,設計間隙為0.01~0.O5mm,該間隙可根據螺桿泵的用途進行適當選擇.
螺旋面與螺桿襯套之間形成空間,油被封閉在該空間中.主動螺桿轉動時,油從吸入端被送至排出端.該密封腔沿抽向可形成數個,密封腔內的壓力逐級升高,故油在排出時壓力不會發生急劇變化.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定的。可實際上,油中含有空氣,以致有可壓縮比,因此排出壓力會有脈動,不過該壓力脈動值較小,約為排出壓力的2~5%.螺桿泵的噪聲和振動都比其它泵小,其噪聲小于10dB(A)。
螺桿泵與齒輪泵的不同點在于:主動螺桿不驅勸從功螺桿,從動螺桿的迥轉力來自排出壓力,這就是說,主動螺桿不把力傳遞給從動螺桿,從動螺桿也能迥轉。如圖2所示,螺桿泵可以設計成圖中(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
