TRSNH940-46三螺桿泵壓縮機(jī)潤(rùn)滑油泵
SNH940R36U12.1W2高壓液壓設(shè)備螺桿泵
3.螺桿泵應(yīng)用于高壓液壓設(shè)備
剛開(kāi)始引進(jìn)螺桿泵是作為潛水艇的液壓泵使用的,僅限于特殊用途,而現(xiàn)在由于螺桿泵的排出壓力可達(dá)25MPa.因此已用于船用絞車(chē)等多種設(shè)備
高壓螺桿泵須解決的zui大問(wèn)題是盡量減少降低容積效率的內(nèi)部泄漏。
內(nèi)部泄漏的主要原困如下:
(i)螺桿嚙合部位的泄漏
(ii)螺桿襯套內(nèi)螺桿邊緣型線(xiàn)部位修正引起的泄漏
(iii)螺旋部分外圓與螺桿襯套之間的泄漏 ,
(iv)因冷卻軸封引起帕泄漏
zui大的泄漏原因是由上述(i)引起的。
由于主動(dòng)螺桿和從動(dòng)螺桿的嚙合部分靠線(xiàn)接觸進(jìn)行密封,并且壓差較大,因此,該處的泄漏量占總泄漏量60%以上。但是,通過(guò)提高機(jī)加工精度,以及采用不受排出壓力影響的泵結(jié)構(gòu),可將螺桿間的間隙由過(guò)去的O.04~O.05mm減小到O.01~O.03mm。
從動(dòng)螺桿的外圓與螺桿襯套內(nèi)孔的滑動(dòng)是阻礙螺桿泵實(shí)現(xiàn)高壓化的主要原因,這個(gè)問(wèn)題現(xiàn)已通過(guò)減小表面粗糙度。加長(zhǎng)螺桿長(zhǎng)度以及降低平均表面壓力得到了解決。
高壓泵的性能。泵的內(nèi)部泄漏量與轉(zhuǎn)速無(wú)關(guān),是一定的,所以高速轉(zhuǎn)邊可提高容積效率。因而,采用轉(zhuǎn)速為3000~3600r/min的小型化泵的實(shí)例也很多。
對(duì)無(wú)回聲室的噪聲頻率分析,要考慮由于泵的噪聲小,所以在設(shè)計(jì)裝置時(shí),要充分地注意電動(dòng)機(jī)噪聲和連結(jié)器的回轉(zhuǎn)噪音,以及油箱和臺(tái)板的剛性。
