?柱塞泵是以液壓缸為工作缸,柱塞作為活塞,通過(guò)柱塞的軸向竄動(dòng)使活塞桿產(chǎn)生向下運(yùn)動(dòng),從而達(dá)到輸送液體或壓縮氣體的目的當(dāng)泵送液體時(shí),柱塞頂入活塞行程中,柱塞產(chǎn)生頂起,活塞上推,帶動(dòng)活塞和連桿產(chǎn)生運(yùn)動(dòng),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(dòng)時(shí),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(huì)隨著工作的進(jìn)行而逐漸磨損,當(dāng)工作到一定程度時(shí)會(huì)出現(xiàn)磨損程度,嚴(yán)重時(shí)可能導(dǎo)致活塞和缸體都被損壞而報(bào)廢。

因此我們必須注意保護(hù)柱塞下面我來(lái)給大家介紹一下在柱塞泵中缸體柱塞會(huì)發(fā)生什么?我們?cè)趯?shí)際生產(chǎn)中應(yīng)該如何保養(yǎng)呢? 1、影響活塞運(yùn)動(dòng)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(dòng)時(shí),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(shí)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(zhǎng)而推動(dòng)阻力也相應(yīng)增大,這樣就使活塞上推動(dòng)作持續(xù)時(shí)間延長(zhǎng)和活塞運(yùn)動(dòng)效率降低。

此外,活塞上推的活塞往復(fù)運(yùn)動(dòng)過(guò)程中也將不可避免地產(chǎn)生運(yùn)動(dòng)副摩擦噪聲當(dāng)活塞往復(fù)運(yùn)動(dòng)過(guò)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(guò)多時(shí),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(dòng)副摩擦也會(huì)使活塞在工作過(guò)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(lái)源,它會(huì)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(huì)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?yàn)槟Σ了?,所以要避免柱塞出現(xiàn)漏油現(xiàn)象一定要注意以下幾點(diǎn):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(dòng)軌跡不正 當(dāng)壓力下降時(shí),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(dòng)軌跡不正如活塞運(yùn)動(dòng)軌跡不正,也會(huì)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(lái)選擇合適的柱塞型號(hào)和長(zhǎng)度隨著工作溫度的升高,密封圈會(huì)產(chǎn)生變化,因此安裝時(shí)間較長(zhǎng)時(shí)必須定期更換密封圈在柱塞裝配時(shí),應(yīng)注意間隙 90L100-KA-1-NN-60-S-4-C7-D-03-GBA-35-35-28
