REXROTH葉片泵工作方法：

Rexroth力士樂(lè)葉片泵機(jī)組屬限壓式變量葉片泵，具有壓力調(diào)整裝置和流量調(diào)整裝置。泵的輸出流量可根據(jù)負(fù)載變化自動(dòng)調(diào)節(jié)，使其輸出功率與負(fù)載工作速度和負(fù)載大小相適應(yīng)，具有高效、節(jié)能、安全可靠、*等特點(diǎn)，特別適用于作容積調(diào)速的液壓系統(tǒng)中的動(dòng)力源，如金屬切削機(jī)床、壓力機(jī)械、皮革機(jī)械、液壓站等。 變量葉片泵機(jī)組具有壓力調(diào)整和流量調(diào)節(jié)裝置， 當(dāng)系統(tǒng)壓力高于葉片泵調(diào)定的壓力時(shí)流量會(huì)減少，使功率損失降為zui低，效率高，安全可靠，側(cè)板采用液壓平衡，可獲得更好的容積效率，采用數(shù)種隔音防振的機(jī)構(gòu)，低噪聲，無(wú)振動(dòng)。

力士樂(lè)葉片泵反應(yīng)快，滯回時(shí)間短 
力士樂(lè)葉片泵控制響應(yīng)時(shí)間短 
力士樂(lè)葉片泵可和標(biāo)準(zhǔn)泵組接 
力士樂(lè)葉片泵PV7-17/10-14REMCO-16 
力士樂(lè)葉片泵帶先導(dǎo)控制的變量葉片泵zui大工作壓力160 bar，zui大流量270 bar。 
力士樂(lè)葉片泵采用油膜承載的滑動(dòng)軸承，軸承壽命長(zhǎng)； 
力士樂(lè)葉片泵壓力和流量控制機(jī)構(gòu)； 
力士樂(lè)葉片泵滯回??； PV7-1A/10-20RE01MC0-08
力士樂(lè)葉片泵對(duì)行程兩位元控制，有很短的控制時(shí)間； 
力士樂(lè)葉片泵適宜用HETG和HEES油液； 
力士樂(lè)葉片泵標(biāo)準(zhǔn)的PV7泵能組合成多種形式的組合泵； 
力士樂(lè)葉片泵PV7泵同樣能和內(nèi)、外齒輪泵和徑向柱塞泵和軸向柱塞泵組合

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，力士樂(lè)葉片泵高轉(zhuǎn)速的螺桿泵雖能增加了流量和揚(yáng)程，力士樂(lè)葉片泵但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過(guò)早失效，力士樂(lè)葉片泵而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長(zhǎng)度很短，極易磨損力士樂(lè)葉片泵，因而縮短了螺桿泵的使用壽命。

力士樂(lè)葉片泵通過(guò)減速機(jī)構(gòu)或無(wú)級(jí)調(diào)速機(jī)構(gòu)來(lái)降低轉(zhuǎn)速，力士樂(lè)葉片泵使其轉(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。

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，力士樂(lè)葉片泵為此，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置，力士樂(lè)葉片泵當(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，力士樂(lè)葉片泵真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。
