PA4VSG125HD1/30W-PPB10N000N組圖
技術(shù)特性:斜盤結(jié)構(gòu)軸向柱塞變量泵,適用于閉式回路的靜液傳動。流量與驅(qū)動轉(zhuǎn)速和排量成比例可無級調(diào)節(jié)。隨著斜盤擺動角度增加,流量從零至最大值。當(dāng)斜盤擺動經(jīng)過零位時,液流方向平穩(wěn)換向。良好適應(yīng)性的多種形式控制和調(diào)節(jié)功能。高壓側(cè)的兩個溢流閥保護(hù)液壓傳動元件(泵和馬達(dá))不過載,高壓溢流閥同時作為補油壓閥。內(nèi)置輔助泵作為補油和控制油泵。通過內(nèi)裝的補油溢流閥限制最大補油壓力。

柱塞泵具有一定的自吸能力,但自吸的高度不宜超過500mm,并且嚴(yán)禁在吸入管道上安裝濾油器,吸入管道直徑不小于推薦數(shù)值,另外自吸時一定要把泵先調(diào)至全偏角。
在轉(zhuǎn)速超過1500rpm時,宜采用供油,供油壓力為0.7MPa左右。在開式系統(tǒng)中,供油泵的流量應(yīng)為該泵的130%,在閉式系統(tǒng)中,供油泵的流量應(yīng)為該泵的35%。

我國液壓行業(yè)企業(yè)近年來加工手段和能力得到大幅提高,但是在表面處理的工藝上存在較大問題,因而產(chǎn)品壽命低,材料熱處理、表面處理、鑄造件、鍛造件等問題是提高產(chǎn)品壽命的主要手段,只有大力推廣先進(jìn)的表面處理的工藝,才能提高液壓產(chǎn)品的使用壽命。
