?液壓泵的結(jié)構(gòu)比較簡單，液壓缸連接處采用焊接密封，可避免泄漏，操作簡單液壓泵是由缸體、活塞、閥體、密封件等部件組成其中缸體起到密封，支撐缸面密封是液壓泵中不可缺少且使用壽命最長的部件之一因此對整個泵是很重要的，但液壓泵在使用中也有一些問題需要我們注意：1、不要在油液中混入異物造成堵塞：影響液壓站輸油質(zhì)量；2、不能在高粘度液壓站中輸送粘度過大的回液需要更換油液或者換油時更換過濾器；3、泵體、螺桿之間的接觸面不能過大或過小造成壓力過大；或者過大造成壓力不足造成動作遲緩;4、堵塞現(xiàn)象：油液不能正常流動；吸油管堵塞；油液中含雜質(zhì)或異物；以及漏油；軸承損壞；系統(tǒng)堵塞（如油封損壞）。
1、泵的液壓系統(tǒng)，主要由管路、液壓閥、液壓缸及密封件組成 管路和液壓閥由油箱和泵體等部分組成采用管路和油箱相互連通的系統(tǒng)管路的接頭用焊接連接，起到密封的作用液壓閥、密封元件均為優(yōu)質(zhì)密封材料制成 2、泵的液壓工作原理是通過液壓泵的動作，帶動泵體中的活塞向外做往復(fù)運(yùn)動直至將液體輸送至各個位置。
為了保證液壓泵的正常工作，液壓泵和活塞都要嚴(yán)格按規(guī)定尺寸加工制作在使用中要注意操作方式，使動作合理，不要讓金屬絲等異物進(jìn)入液壓泵和管路里不要讓里面的潤滑油被雜物堵塞或者是腐蝕以免造成油泵漏油，損壞泵內(nèi)元件。
3、在輸送液體時，需要保證各個部位，尤其是油泵部分一定要保證良好的密封狀況 如果液壓泵出現(xiàn)堵塞現(xiàn)象，請停止工作，打開閥門，使油液流入回液缸內(nèi)并及時排出然后在手動控制閥門的作用下，切斷進(jìn)油路防止液壓油流入油缸。
這樣液壓油就能順利通過通道進(jìn)入油箱，實(shí)現(xiàn)回油再循環(huán)這樣，如果沒有回油壓力，再由泵輸送回油，這樣才能保證液壓站工作正常、使用壽命長 4、在使用過程中，要經(jīng)常檢查各部位螺栓是否松動 壓力不足經(jīng)常檢查油封是否完好，是否有滲漏現(xiàn)象，如有應(yīng)及時更換。
密封必須良好密封處應(yīng)經(jīng)常清洗，保持清潔避免雜物進(jìn)入壓力表內(nèi)部以及排氣孔等地方，以免造成堵塞現(xiàn)象出現(xiàn)活塞及密封圈損壞：如果有破裂，在更換新件時一定要進(jìn)行修復(fù)；使用后不可在水中清洗或用汽油等溶劑清洗泵表面或用海綿擦去表面粘附的水分。
