詳細介紹
REXROTH力士樂變量柱塞泵力士樂變量柱塞泵是往復泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉(zhuǎn)動驅(qū)動,往復運動,其吸入和排出閥都是單向閥。
當柱塞外拉時,工作室內(nèi)壓力降低,出口閥關(guān)閉,低于進口壓力時,進口閥打開,液體進入;柱塞內(nèi)推時,工作室壓力升高,
進口閥關(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。
REXROTH柱塞泵故障現(xiàn)象
(1)故障現(xiàn)象:泵不能排料
齒輪泵 整機圖片(3張)
故障原因:a、旋轉(zhuǎn)方向相反;b、吸入或排出閥關(guān)閉; c、入口無料或壓力過低; d、粘度過高,泵無法咬料
對策: a、確認旋轉(zhuǎn)方向; b、確認閥門是否關(guān)閉; c、檢查閥門和壓力表; d、檢查液體粘度,以低速運轉(zhuǎn)時按轉(zhuǎn)速比例的流量是否出現(xiàn),若有流量,則流入不足、
流量不足
(2)故障現(xiàn)象:泵流量不足
KCB300齒輪泵
故障原因:a、吸入或排出閥關(guān)閉; b、入口壓力低; c、出口管線堵塞; d、填料箱泄漏;e、轉(zhuǎn)速過低
對策:a、確認閥門是否關(guān)閉;b、檢查閥門是否打開;c、確認排出量是否正常; d、緊固;大量泄露漏影響生產(chǎn)時,應停止運轉(zhuǎn),拆卸檢查; e、檢查泵軸實際轉(zhuǎn)速;
