英國Bert伯特進(jìn)口變量柱塞泵概述
變量柱塞泵的壓力油經(jīng)泵體、泵殼變量殼體中的通油孔通過單向閥進(jìn)入變量殼體的下腔,當(dāng)拉桿向下運(yùn)動(dòng)時(shí),推動(dòng)伺服活塞向下移動(dòng),伺服閥的上閥口打開,變量殼體下腔的壓力油經(jīng)變量活塞中的通油孔進(jìn)入變量殼體上腔,由于上腔面積大于下腔,液壓力推動(dòng)活塞向下運(yùn)動(dòng),帶動(dòng)銷軸使變量頭繞鋼球中心旋轉(zhuǎn),改變變量頭的傾斜角(增大),柱塞泵的流量隨之增大。反之拉桿向上運(yùn)動(dòng),變量頭的傾斜角向相反方向變化,泵的流量也隨之變化。當(dāng)傾斜角度變至零以后,則變量頭向負(fù)偏角方向變化,液流產(chǎn)生換向,泵的進(jìn)出油口變換。
英國Bert伯特進(jìn)口變量柱塞泵的特點(diǎn):
變量柱塞泵有軸向變量柱塞泵和徑向變量柱塞泵兩種。
現(xiàn)以軸向變量柱塞泵為例來說明其工作原理:
當(dāng)電動(dòng)機(jī)帶動(dòng)傳動(dòng)軸旋轉(zhuǎn)時(shí),泵缸與柱塞一同旋轉(zhuǎn),柱塞頭與斜盤保持接觸,斜盤與缸體成一角度,斜盤不轉(zhuǎn)。當(dāng)缸體旋轉(zhuǎn)時(shí),由于斜盤的斜面作用,柱塞就會(huì)在泵缸中做往復(fù)運(yùn)動(dòng)。當(dāng)柱塞轉(zhuǎn)到斜盤低點(diǎn),柱塞缸容積逐漸增大,因此液體經(jīng)配油盤的吸油口吸人油缸;而當(dāng)柱塞轉(zhuǎn)到斜盤高點(diǎn),柱塞缸容積逐漸減小,油缸內(nèi)液體經(jīng)配油盤的出口排出液體。只要傳動(dòng)軸不斷旋轉(zhuǎn),液體就會(huì)不斷地被吸入和排出。
改變斜盤的角度,就可以改變柱塞在泵缸內(nèi)的行程長(zhǎng)度,即可改變泵的流量。傾斜角度固定的稱為定量泵,傾斜角度可以改變的便稱為變量泵。
