     3.螺桿泵應用于高壓液壓設備
      剛開始引進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25MPa.因此已用于船用絞車等多種設備
      高壓螺桿泵須解決的zui大問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。
     由于主動螺桿和從動螺桿的嚙合部分靠線接觸進行密封,并且壓差較大,因此,該處的泄漏量占總泄漏量60%以上。但是,通過提高機加工精度,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去的O.04~O.05mm減小到O.01~O.03mm。
     從動螺桿的外圓與螺桿襯套內(nèi)孔的滑動是阻礙螺桿泵實現(xiàn)高壓化的主要原因,這個問題現(xiàn)已通過減小表面粗糙度。加長螺桿長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)速無關,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的小型化泵的實例也很多。
     對無回聲室的噪聲頻率分析,要考慮由于泵的噪聲小,所以在設計裝置時,要充分地注意電動機噪聲和連結(jié)器的回轉(zhuǎn)噪音,以及油箱和臺板的剛性。
