現(xiàn)在市場(chǎng)上的螺桿泵的種類較多,，相對(duì)而言,，的螺桿泵設(shè)計(jì)合理，材質(zhì)精良,，但格較高,，服務(wù)方面有的不到位，配件格高,，訂貨周期長(zhǎng),，可能影響生產(chǎn)的正常運(yùn)行。
 生產(chǎn)的大都仿制,，質(zhì)量良莠不齊,，在選用生產(chǎn)的時(shí)，在考慮其性比的時(shí)候,，選用轉(zhuǎn)速,，長(zhǎng)導(dǎo)程，傳動(dòng)量部件材質(zhì)優(yōu)良,，額定壽命長(zhǎng)的,。
REXROTH葉片泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，經(jīng)發(fā)生,，橡膠定子由于干摩擦,，瞬間產(chǎn)生高溫而燒壞，所以,，粉碎機(jī)完,，格柵暢通是螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之，為此,，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置,，當(dāng)發(fā)生斷料時(shí)，由于螺桿泵其有自吸功能的特性,，腔體內(nèi)會(huì)產(chǎn)生真空,，真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。

REXROTH葉片泵是種容積式回轉(zhuǎn)泵,，當(dāng)出口端受阻以后,，壓力會(huì)逐漸升高,，以至于超過(guò)預(yù)定的壓力值,。此時(shí)電機(jī)負(fù)荷急劇增加。傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值,，嚴(yán)重時(shí)會(huì)發(fā)生電機(jī)燒毀,、傳動(dòng)零件斷裂。為了避免螺桿泵損壞,，般會(huì)在螺桿泵出口處安裝旁通溢流閥,，用以穩(wěn)定出口壓力,，保持泵的正常運(yùn)轉(zhuǎn)。
REXROTH葉片泵只不過(guò)是離心泵的種具體應(yīng)用的泵而命名,。實(shí)質(zhì)上砂泵只是個(gè)籠統(tǒng)的叫法,。般主要用在礦業(yè)，煤炭,，冶金,，化工，環(huán)保等行業(yè),。般意義的砂泵多是指用在環(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,。
REXROTH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,，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(guò)流部件材質(zhì)采用高硬度的耐磨合金鑄鐵。
