德國Rexroth力士樂定量柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復運動，使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點，被廣泛應用于高壓、大流量和流量需要調(diào)節(jié)的場合，諸如液壓機、工程機械和船舶中。機械分類 ? 軸向式 ? 直軸斜盤式  ? 徑向式 ? 液壓式 柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。
德國Rexroth力士樂葉片泵機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)負載變化自動調(diào)節(jié)，使其輸出功率與負載工作速度和負載大小相適應，具有、節(jié)能、安全可靠、*等特點，特別適用于作容積調(diào)速的液壓系統(tǒng)中的動力源，如金屬切削機床、壓力機械、皮革機械、液壓站等。 變量葉片泵機組具有壓力調(diào)整和流量調(diào)節(jié)裝置， 當系統(tǒng)壓力高于葉片泵調(diào)定的壓力時流量會減少,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)種隔音防振的機構(gòu),低噪聲,無振動。
力士樂(Bosch Rexroth)為中匯液壓工業(yè)及工廠自動化、行走機械、以及可再生能源領(lǐng)域的客戶提供傳動、控制與移動解決方案;作為超過50萬客戶的共同選擇，力士樂正不斷像中匯液壓這樣為客戶提供高質(zhì)量的電控、液壓、氣動以及機電一體化元件和系統(tǒng)。Bosch Rexroth博世-力士樂氣動產(chǎn)品大量應用在鉆修設備的氣路上，以及Caterpillar卡特匹勒與Allison艾里遜變速箱的配合中以實現(xiàn)動力的操作和控制。以Bosch Rexroth博世-力士樂高性能的中匯液壓產(chǎn)品為依托，Rexroth向鋼鐵行業(yè)提供連鑄、連軋等生產(chǎn)線的全套液壓系統(tǒng)和液壓元件。Bosch Rexroth博世-力士樂在船舶和海洋鉆井平臺的液壓和氣動傳動系統(tǒng)及控制方面具有淵博的經(jīng)驗，產(chǎn)品應用在鉆井平臺、推進系統(tǒng)、舵機系統(tǒng)、發(fā)動機控制系統(tǒng)。
