?如果壓力不足，可以通過(guò)液壓油來(lái)補(bǔ)充和潤(rùn)滑活塞表面的磨損由于柱塞的行程較短，油液的流動(dòng)性差，因此油的粘度和油膜容易被破壞，從而導(dǎo)致油霧形成此時(shí)若繼續(xù)噴射會(huì)損壞油液混合體（即油泥）和潤(rùn)滑面（即潤(rùn)滑層）導(dǎo)致磨損。
一般只能通過(guò)更換液壓油來(lái)解決當(dāng)油泵輸出壓力低于要求時(shí)，應(yīng)進(jìn)行調(diào)節(jié)裝置調(diào)整柱塞孔和進(jìn)氣口的氣量不應(yīng)過(guò)大或過(guò)小當(dāng)泵吸不上氣時(shí)，應(yīng)檢查各元件是否損壞？油位是否在允許值內(nèi)？是否有油泥等如果油液在流動(dòng)過(guò)程中出現(xiàn)泡沫并且不斷溢出并在空中飄蕩而形成氣泡，則應(yīng)清洗液壓系統(tǒng)和濾網(wǎng)；如果出現(xiàn)故障或未清理干凈就重新進(jìn)行工作，直到發(fā)動(dòng)機(jī)內(nèi)空氣完全排出為止！柱塞泵不出氣除了這一原因外還有可能是氣門座密封墊圈損壞或活塞密封環(huán)失效導(dǎo)致柱塞泵壓力不足而引起的泵不出氣是由于氣缸內(nèi)壓力過(guò)低而引起的，壓力低導(dǎo)致柱塞泵泵頭處于空轉(zhuǎn)狀態(tài)。
當(dāng)活塞和運(yùn)動(dòng)時(shí)必須克服相對(duì)運(yùn)動(dòng)（即壓縮空氣）所產(chǎn)生的巨大動(dòng)力源壓力（因?yàn)樗仨毻ㄟ^(guò)柱塞孔被壓縮） 如果活塞運(yùn)動(dòng)，缸徑越大，缸內(nèi)壓力越高，但不能克服活塞相對(duì)運(yùn)動(dòng)產(chǎn)生的力源壓力缸工作時(shí)所需的壓縮比也是根據(jù)活塞和運(yùn)動(dòng)之間的相對(duì)速度來(lái)決定的，而不是通過(guò)柱塞孔來(lái)決定。
由于進(jìn)壓力較大，因此從系統(tǒng)中流出的空氣將導(dǎo)致較大的能量損失，從而造成燃油、液壓油或氣體混入系統(tǒng)中以降低其質(zhì)量這會(huì)導(dǎo)致壓力表指針不動(dòng)，或無(wú)法精確定位這將影響系統(tǒng)整體性能這也是為什么氣缸密封可能很差或者磨損很快。
