螺桿泵應(yīng)用于液壓電梯
從市場上螺桿泵的銷售情況來看,其大多數(shù)還是用于液壓電梯。采用螺桿泵的液壓電梯,分為用油缸直接將電梯轎箱推上和通過滑輪間接地推轎箱兩種方式。作為液壓設(shè)備用,油泵的排出壓力為2.9~4.9MPa、排量為3001/min,上述參數(shù)范圍的油泵采用較多。
由于要求減小轎箱的振動,使其與建筑物具有同等的使用壽命,所以建筑物的載人電梯幾乎都采用螺桿泵。歐美一些國家多采用油浸式,即把電功機(jī)和油泵設(shè)置在油箱內(nèi),而日本則主要考慮效率和維護(hù)問題,故采用帶式驅(qū)勸型。
決定電梯的乘坐舒適度灼因素之一是泵的排出壓力脈動。螺桿泵內(nèi)形成的密封腔在泵的排出端,泵回轉(zhuǎn)1周密封腔啟開2次,所以脈功一26圖3排出壓力脈動波形實例的基本頻率是泵轉(zhuǎn)速的2倍。啟開處的密封腔壓力與排出壓力的壓差較小,但為了進(jìn)一步減小脈動值,還需想些辦法,使排出壓力接近啟開處壓力。
另外,由于泵與電動機(jī)的對中心不良、螺桿彎曲、二條螺旋槽深度存在誤差等原因,有時會產(chǎn)生基本頻率是泵轉(zhuǎn)速1倍的脈動,及由于從動螺桿在螺桿襯套內(nèi)擺動,有時會產(chǎn)生基本頻率是泵轉(zhuǎn)速1/2的脈動。
特別是后一種情況更容易發(fā)生,但當(dāng)排出壓力一升高,這種情況也就不存在了。
