?柱塞泵是以液壓缸為工作缸，柱塞作為活塞，通過柱塞的軸向竄動使活塞桿產(chǎn)生向下運(yùn)動，從而達(dá)到輸送液體或壓縮氣體的目的當(dāng)泵送液體時，柱塞頂入活塞行程中，柱塞產(chǎn)生頂起，活塞上推，帶動活塞和連桿產(chǎn)生運(yùn)動，使柱塞在缸體上得到壓縮。
當(dāng)柱塞在活塞缸內(nèi)做往復(fù)運(yùn)動時，在其內(nèi)部產(chǎn)生真空，氣體被壓縮到柱塞而排出以達(dá)到壓縮液體的目的柱塞是柱塞泵的核心部件部分，它會隨著工作的進(jìn)行而逐漸磨損，當(dāng)工作到一定程度時會出現(xiàn)磨損程度，嚴(yán)重時可能導(dǎo)致活塞和缸體都被損壞而報廢。
因此我們必須注意保護(hù)柱塞下面我來給大家介紹一下在柱塞泵中缸體柱塞會發(fā)生什么？我們在實際生產(chǎn)中應(yīng)該如何保養(yǎng)呢？ 1、影響活塞運(yùn)動效率 缸內(nèi)柱塞與活塞之間的配合間隙直接影響到活塞上推，從而使活塞向下力矩增大，柱塞也隨之加大，使活塞的受力更大。
當(dāng)活塞向下運(yùn)動時，柱塞受到推力而發(fā)生偏轉(zhuǎn)角度變化，將其力傳遞給活塞上推，從而使活塞向下力矩增大的同時造成活塞的受力也增大，由于這種變化，導(dǎo)致行程不斷延長而推動阻力也相應(yīng)增大，這樣就使活塞上推動作持續(xù)時間延長和活塞運(yùn)動效率降低。
此外，活塞上推的活塞往復(fù)運(yùn)動過程中也將不可避免地產(chǎn)生運(yùn)動副摩擦噪聲當(dāng)活塞往復(fù)運(yùn)動過程中產(chǎn)生的熱量及壓縮空氣在活塞行程末段的混合氣過多時，產(chǎn)生了較多蒸汽及粉塵飛揚(yáng)，造成活塞上推阻力增大此外，汽缸壁與活塞之間的運(yùn)動副摩擦也會使活塞在工作過程中產(chǎn)生噪音。
2、產(chǎn)生泄漏 柱塞的泄漏是柱塞泵工作壓力的主要來源，它會引起活塞及缸體的磨損，最終導(dǎo)致活塞、缸體和連桿都損壞活塞及連桿損壞會使液壓系統(tǒng)的壓力降低，最終造成缸體內(nèi)的壓力增大，從而導(dǎo)致缸體與活塞間產(chǎn)生密封泄漏，引起氣阻損壞氣缸。
柱塞產(chǎn)生泄漏的原因主要是活塞之間因為摩擦所致，所以要避免柱塞出現(xiàn)漏油現(xiàn)象一定要注意以下幾點：①要避免活塞與連桿之間產(chǎn)生撞擊；②要避免與空氣混合，以免污染活塞與缸體以及活塞與氣缸套接觸部分③要避免柱塞接觸活塞環(huán)，以免其因間隙變化造成壓力損失。
④要避免高壓油流入柱塞，避免產(chǎn)生汽蝕⑤要避免柱塞本身產(chǎn)生氣泡所引起氣阻的產(chǎn)生 3、活塞運(yùn)動軌跡不正 當(dāng)壓力下降時，柱塞因內(nèi)部的壓力而上升，而柱塞本身的彈性又阻止了柱塞間的間隙減小，而造成運(yùn)動軌跡不正如活塞運(yùn)動軌跡不正，也會導(dǎo)致活塞被損壞。
保養(yǎng)建議：根據(jù)環(huán)境溫度、壓力和工作溫度來選擇合適的柱塞型號和長度隨著工作溫度的升高，密封圈會產(chǎn)生變化，因此安裝時間較長時必須定期更換密封圈在柱塞裝配時，應(yīng)注意間隙 90L100-KA-1-NN-60-S-4-C7-D-03-GBA-35-35-28 90L100KA1NN60S4C7D03GBA353528
