?泵體之間的間隙過大也會(huì)導(dǎo)致泵不出油對(duì)于泵體之間間隙過大，應(yīng)先在泵體處加注一批潤滑劑，然后再用來泵入泵體內(nèi)；如果泵體之間間隙過小，應(yīng)將泵內(nèi)液體吸凈，再用新液位計(jì)檢測液面高度來確定泵體內(nèi)的位置；如果泵內(nèi)液體濃度太高會(huì)造成油中含有大量水分，此時(shí)應(yīng)重新加油；如果泵體上粘有膠狀物體也可能導(dǎo)致液體泄漏；另外還要注意檢查電磁閥是否正常良好；液壓油過臟會(huì)導(dǎo)致壓力表不能正常顯示；如果壓力下降到正常值后就開始停機(jī)了；對(duì)于泵內(nèi)有異物堵塞可能導(dǎo)致油泵在工作中無法工作；如果壓力表有明顯響聲，表明是液壓管路中的油管與泵體密封損壞造成液壓腔中充滿空氣，由于壓力過高而使泵不出油或無油，應(yīng)及時(shí)更換液壓油箱內(nèi)堵塞較大的油管及泵體其他部件；對(duì)于密封圈損壞會(huì)導(dǎo)致液壓管路出現(xiàn)泄漏。
如果液壓元件損壞，會(huì)使其輸出電壓、工作壓力等出現(xiàn)偏差，從而使其不能工作，甚至停機(jī)所以應(yīng)及時(shí)更換或修理密封圈、液壓元件如果液壓元件已經(jīng)老化，也應(yīng)及時(shí)更換換油方法是：拆下?lián)p壞嚴(yán)重的液壓元件，拆下油底殼檢查液壓油是否有變質(zhì)并更換新液壓元件。
檢查液壓油時(shí)一定要注意其壓力是否達(dá)到標(biāo)準(zhǔn)規(guī)定的值，當(dāng)液壓油過高或過低都不會(huì)起作用檢查液壓元件時(shí)，應(yīng)注意其工作介質(zhì)是否與液壓元件工作介質(zhì)不相容，若不相容首先檢查有無泄漏現(xiàn)象，然后再判斷其工作介質(zhì)類型，如液壓油因環(huán)境濕度大而變質(zhì)嚴(yán)重時(shí)應(yīng)更換新液壓元件；若液壓元件已老化或損壞很嚴(yán)重必須更換，則必須將液壓元件放在通風(fēng)陰涼處保管，直到其不再工作為止。
