德國REXROTH力士樂葉片泵
REXROTH力士樂葉片泵因其有可變量輸送,、自吸能力強(qiáng),、可逆轉(zhuǎn),、能輸送含固體顆粒的液體等特點(diǎn),，在污水處理廠中，廣泛地被使用在輸送水,、濕污泥和絮凝劑藥液方面,。螺桿泵選用應(yīng)遵循經(jīng)濟(jì)、合理,、可靠的原則,。如果在設(shè)計(jì)選型方面考慮不周，會(huì)給以后的使用,、管理,、維修帶來麻煩，所以選用一臺(tái)按生產(chǎn)實(shí)際需要,，合理可靠的螺桿泵既能保證生產(chǎn)順利進(jìn)行,，又可降低修理成本。

一,、德國REXROTH力士樂葉片泵的轉(zhuǎn)速選用：
REXROTH葉片泵的流量與轉(zhuǎn)速成線性關(guān)系,，相對(duì)于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖能增加了流量和揚(yáng)程,，但功率明顯增大,，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長(zhǎng)度很短,，極易磨損,，因而縮短了螺桿泵的使用壽命。 通過減速機(jī)構(gòu)或無級(jí)調(diào)速機(jī)構(gòu)來降低轉(zhuǎn)速,，使其轉(zhuǎn)速保持在每分三百轉(zhuǎn)以下較為合理的范圍內(nèi),，與高速運(yùn)轉(zhuǎn)的螺桿泵相比，使用壽命能延長(zhǎng)幾倍,。 

二,、REXROTH力士樂葉片泵的品質(zhì)：
現(xiàn)在市場(chǎng)上的螺桿泵的種類較多，相對(duì)而言,，進(jìn)口的螺桿泵設(shè)計(jì)合理,，材質(zhì)精良，但價(jià)格較高,，服務(wù)方面有的不到位,，配件價(jià)格高，訂貨周期長(zhǎng),，可能影響生產(chǎn)的正常運(yùn)行,。 國內(nèi)生產(chǎn)的大都仿制進(jìn)口產(chǎn)品，產(chǎn)品質(zhì)量良莠不齊,，在選用國內(nèi)生產(chǎn)的產(chǎn)品時(shí),，在考慮其性價(jià)比的時(shí)候，選用低轉(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)的產(chǎn)品,。

三,、REXROTH力士樂葉片泵確保雜物不進(jìn)入泵體：
濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞,，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī),，也有的安裝格柵裝置或?yàn)V網(wǎng),，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞,。

四,、REXROTH力士樂葉片泵避免斷料：
REXROTH葉片泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(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)完好,，格柵暢通是螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之一,，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),。 

五、REXROTH力士樂葉片泵保持恒定的出口壓力：
德國REXROTH力士樂葉片泵是一種容積式回轉(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，一般會(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)。

力士樂REXROTH葉片泵的管理要點(diǎn)除需防干轉(zhuǎn)和過載,、防吸入空氣和吸入真空度過大外,，還應(yīng)注意：
    1．力士樂泵轉(zhuǎn)向改變,，則其吸排方向也改變?nèi)~片泵都有規(guī)定的轉(zhuǎn)向,，不允許反。因?yàn)檗D(zhuǎn)子葉槽有傾斜,，葉片有倒角,，葉片底部與排油腔通，配油盤上的節(jié)流槽和吸,、排口是按既定轉(zhuǎn)向設(shè)計(jì),。可逆轉(zhuǎn)的葉片泵必須專門設(shè)計(jì),。
    2．REXROTH葉片泵裝配 配油盤與定子用定位銷正確定位,，葉片、轉(zhuǎn)子,、配油盤都不得裝反,，定子內(nèi)表面吸入?yún)^(qū)部分zui易磨損,，必要時(shí)可將其翻轉(zhuǎn)安裝，以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用,。
    3．力士樂泵的拆裝 注意工作表面清潔,，工作時(shí)油液應(yīng)很好過濾。
    4. 葉片在葉槽中的間隙太大會(huì)使漏泄增加,，太小則葉片不能自由伸縮,，會(huì)導(dǎo)致工作失常。
    5．德國力士樂葉片泵的軸向間隙 對(duì)ηv影響很大,。
    1)小型泵-0.015～0.03mm
    2)中型泵-0.02～0.045mm
    6．油液的溫度和粘度 一般不宜超過55℃,，粘度要求在17～37mm2/s之間。粘度太大則吸油困難,；粘度太小則漏泄嚴(yán)重,。作為泵產(chǎn)品，葉片泵更多地指滑片泵,。

    REXROTH葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí),，葉片在離心力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上,。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積,，先由小到大吸油后再由大到小排油，葉片旋轉(zhuǎn)一周時(shí),，完成一次吸油與排油,。
