?當(dāng)油箱的容積縮小時，就會導(dǎo)致泵頭壓力下降由于柱塞泵安裝在混凝土泵上，所以會有一部分油液進(jìn)入泵體內(nèi)當(dāng)液壓油粘度增加時，油液中還會混入空氣和雜質(zhì)這樣將會使液壓油變稀，泵內(nèi)壓力下降這就會導(dǎo)致吸油嘴吸不上油，此時可適當(dāng)降低柱塞泵壓力。
否則會使系統(tǒng)因產(chǎn)生大量油液而引起發(fā)熱泵體內(nèi)部故障應(yīng)及時檢查故障部件如果問題沒有解決，或者更換新油來解決壓力過高，如果超過該值，那么它就會損壞發(fā)動機(jī)我們應(yīng)該首先檢查泵上有多少油（含雜質(zhì)）來檢查其內(nèi)部是否有堵塞或漏油現(xiàn)象；另外，如果空氣壓力下降，并且泵頭沒有向下排出氣體，則應(yīng)該更換其他部件或清洗。
如果問題不是很嚴(yán)重，也不是油液異常，請在日常檢查中發(fā)現(xiàn)您可以檢查油路是否堵塞（可能是液壓油中有毒物質(zhì)）和油液是否混入雜質(zhì)等原因引起工作環(huán)境改變后導(dǎo)致液壓油質(zhì)量下降并且使系統(tǒng)無法工作：一般認(rèn)為是系統(tǒng)壓力降低或壓力太低、油液過濃或者混入了空氣或雜質(zhì)等原因都會導(dǎo)致系統(tǒng)出現(xiàn)問題。
在這種情況下，柱塞泵停止工作，但不出氣或只出氣，這就是所說的壓力低了這時應(yīng)檢查是不是吸入了空氣或吸入了其他液體而產(chǎn)生故障當(dāng)檢查出壓力時，請您仔細(xì)檢查這一點(diǎn)來解決！首先是檢查柱塞泵電機(jī)是否損壞或有缺陷；然后檢查油和油液是否過?。蝗绻谥诔霈F(xiàn)這種現(xiàn)象，它可能是油液過濃而不是泄漏；將會導(dǎo)致吸氣壓力降低。
在檢查這一點(diǎn)時，應(yīng)該首先檢查吸入油管內(nèi)是否有雜質(zhì)；其次是查看泵頭內(nèi)是否有空氣如果空氣質(zhì)量不好，則可能導(dǎo)致泵油壓力降低或泵頭不出氣如果發(fā)現(xiàn)壓力降低的現(xiàn)象請注意是否與管路堵塞有關(guān)檢查主要是由過濾器是否堵塞導(dǎo)致泄漏。
