力士樂葉片泵PV7-1X/100-150RE07MC5-08原裝現(xiàn)貨

力士樂葉片泵只不過是離心泵的一種具體應(yīng)用的泵而命名。實(shí)質(zhì)上砂泵只是一個(gè)籠統(tǒng)的叫法。一般主要用在礦業(yè)，煤炭，冶金，化工，環(huán)保等行業(yè)。一般意義的砂泵更多是指用在環(huán)保，挖沙，河道清淤等行業(yè)較多。這個(gè)系列砂泵主要以ES或者G系列的較多。除此之外，叫做砂泵的類型還有很多，石油領(lǐng)域的SB砂泵，礦業(yè)上的PS砂泵系列等等。本文介紹的砂泵主要以通常意義上的ES或G系列的挖沙，環(huán)保行業(yè)的用的砂泵。
葉片泵均為臥式、單泵殼結(jié)構(gòu)的離心泵。采用特殊的卡箍夾緊泵體與泵蓋，泵的吐出口方向可在360度的任何一個(gè)位置，安裝使用方便。 砂泵的軸承組件采用圓筒式結(jié)構(gòu)，便于調(diào)整葉輪與泵體之間的間隙，維修時(shí)可整體拆除。軸承采用油脂潤(rùn)滑。砂泵的軸封形式有填料密封、付葉輪密封、機(jī)械密封。砂泵流道寬暢，汽蝕性能好，效率高，耐磨蝕。 傳動(dòng)方式主要有V型三角帶傳動(dòng)、彈性聯(lián)軸器傳動(dòng)、輪減速箱傳動(dòng)、液力偶合器傳動(dòng)、變頻驅(qū)動(dòng)裝置，可控硅調(diào)速等。 過流部件材質(zhì)采用高硬度的耐磨合金鑄鐵。

力士樂葉片泵是活塞或柱塞的往復(fù)運(yùn)動(dòng)方向與缸體中心軸平行的葉片泵。軸向葉片泵是利用與傳動(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時(shí)可以達(dá)到很高的精度配合，因此容積效率高，運(yùn)轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點(diǎn)，但對(duì)液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價(jià)較高。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無需外力供油?？繗鈮汗┯偷囊簤河拖?，在每次啟動(dòng)機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就擔(dān)任機(jī)器，會(huì)對(duì)液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會(huì)造成泵體內(nèi)回程板與壓板的非正常磨損。
