1，液壓傳動基于的傳動原理和組成
潮壓體動是利用波體的靜壓能進行傳遞，控制和轉(zhuǎn)換動力:其主要由動力元件,控
制元件，執(zhí)行元件，輔助元件和液壓油(工作介質(zhì))組成
2:何謂液壓系統(tǒng)的液壓沖擊?原因，危害及預(yù)防措
在液壓系統(tǒng)中:由于某種原因壓力瞬間突然增大的現(xiàn)象稱為現(xiàn)象渡壓沖擊
危害:產(chǎn)生振動，噪音;
系統(tǒng)溫度升高，液壓元件損壞或動作失靈
閥;在液壓元件中設(shè)置緩沖阻尼孔
描施。緩慢扈閉的門:限制管中流速(增大管徑);設(shè)置暮能器<軟管>或安全
3,何謂液壓氣穴現(xiàn)象?原因，危害及預(yù)防措施，
31,何理布質(zhì)樣中，由于壓力降低，表體中迅建產(chǎn)生大里汽泡的現(xiàn)象稱氣穴觀象，
多發(fā)生在閥門和油泵吸入口處:
; 引起系統(tǒng)振動和噪音;嚴重的還會侵蝕元件
(2)危害:造成流量或壓力不穩(wěn)定;
表面，使壽命降低;
零質(zhì):的禮前后壓力差(-般為1/2<3.0降低油源吸油高度(增
元件的抗氣蝕能力
大吸油管內(nèi)徑);合理部局營路(障低管通阻力);提高元{
4何謂滑閥的波壓卡緊現(xiàn)象?原因和消余措施。
4向任限!南志和兩九之目同題很小心，由于某種原因使國隙的摩檀力量大,勖
閥芯移動困雅甚致卡死。這種現(xiàn)象稱為袁壓卡緊:原因:
間隙之間有雜質(zhì)，間隙
越小閥芯和閥禮的幾何形狀誤差(倒維)產(chǎn)生經(jīng)
向不平衡力引起軸向摩擦力
增大.措施:控制
尺寸精度，順錐安裝，柱塞上開均壓槽:軸向顛振,
精密過濾.
