齒輪計(jì)量泵廠家告訴您因困油對計(jì)量泵造成的危害
來源： 發(fā)布時(shí)間：2018-05-07 15:51:47 瀏覽次數(shù)：次
鄭州巴特專業(yè)的齒輪計(jì)量泵制造企業(yè)，國內(nèi)知名的計(jì)量泵研發(fā)生產(chǎn)單位；鄭州齒輪計(jì)量泵廠家針對困油現(xiàn)象的發(fā)生，會對齒輪計(jì)量泵造成哪些危害，進(jìn)行全面的分析解讀。
當(dāng)齒輪計(jì)量泵發(fā)生困油現(xiàn)象，將對工作的平穩(wěn)性和可靠性有很大危害。在中、低壓系統(tǒng)，由于油液壓縮性很小，可略而不計(jì)。而封在困油區(qū)內(nèi)的油液因不適應(yīng)彈性變化必造成下述危害：1、當(dāng)閉死容積縮小時(shí)，困油區(qū)油液受到擠壓并從齒輪泵的零件配合表面的縫隙強(qiáng)行擠出，會使齒輪計(jì)量泵的齒輪、軸套、端蓋和軸承等受到很大的附加載荷(彎曲應(yīng)力、剪切應(yīng)力和壓應(yīng)力等)。這種載荷，一方面會使油溫升高，造成功率損失，降低工作效率；另一方而會使零件加劇磨損，縮短計(jì)量泵的使用壽命。2、當(dāng)閉死容積變大時(shí)，困油區(qū)形成局部真空，使溶解在油液中的氣體被析出、氣化并形成氣泡。這種氣泡，一方面會使齒輪計(jì)量泵加大噪聲，產(chǎn)生氣蝕并破壞嚙合精度，降低工作效率、縮短使用壽命；另一方面會引起系統(tǒng)沖擊和振動，造成齒輪計(jì)量泵的壓力和流量脈動等。
鄭州巴特多年的計(jì)量泵研發(fā)生產(chǎn)經(jīng)驗(yàn)，致力于為國內(nèi)外用戶提供高標(biāo)準(zhǔn)、高性價(jià)比的計(jì)量泵產(chǎn)品，滿足用戶實(shí)際生產(chǎn)需求，大限度的為用戶創(chuàng)造價(jià)值。詳細(xì)了解請咨詢我們24小時(shí)服務(wù)熱線：0371-67993077
