力士樂柱塞泵R910990406現(xiàn)貨代理 力士樂柱塞泵是往復(fù)泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉(zhuǎn)動驅(qū)動,往復(fù)運(yùn)動,其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時,工作室內(nèi)壓力降低,出口閥關(guān)閉,低于進(jìn)口壓力時,進(jìn)口閥打開,液體進(jìn)入;柱塞內(nèi)推時,工作室壓力升高,進(jìn)口閥關(guān)閉,高于出口壓力時,出口閥打開,液體排出。 帶滑靴結(jié)構(gòu)的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵,安放在缸體中的柱塞通過滑靴與斜盤相接觸,當(dāng)傳動軸帶動缸體旋轉(zhuǎn)時,斜盤將柱塞從缸體中拉出或推回,完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機(jī)構(gòu)用來改變斜盤的傾角,通過調(diào)節(jié)斜盤的傾角可改變泵的排量。 rexroth柱塞泵根據(jù)傾斜元件的不同,有斜盤式和斜軸式兩種。斜盤式是斜盤相對回轉(zhuǎn)的缸體有一傾斜角度,而引起柱塞在泵缸中往復(fù)運(yùn)動。傳動軸軸線和缸體軸線是一致的。這種結(jié)構(gòu)較簡單,轉(zhuǎn)速較高,但工作條件要求高,柱塞端部與斜盤的接觸部往往是薄弱環(huán)節(jié)。斜軸式的斜盤軸線與傳動軸軸線是一致的。它是由于柱塞缸體相對傳動軸傾斜一角度而使柱塞作往復(fù)運(yùn)動。流量調(diào)節(jié)依靠擺動柱塞缸體的角度來實現(xiàn),故有的又稱擺缸式。它與斜盤式相比,工作可靠,流量大,但結(jié)構(gòu)復(fù)雜。柱塞泵。但它又不同于往復(fù)式柱塞泵,因為它的柱塞不僅在泵缸內(nèi)做往復(fù)運(yùn)動,而且柱塞和泵缸與斜盤相對有旋轉(zhuǎn)運(yùn)動。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽,它們彼此由隔墻隔開,保證一定的密封性,它們分別與泵的進(jìn)油口和出油口連通。 R910945178AA10VSO18DFR1/31R-PPA12N00
