操作過(guò)力士樂(lè)葉片泵的用戶都了解，力士樂(lè)葉片泵多作為神、低液壓源使用。注意使用液壓油的粘度，推薦使用2.5-5°E50粘度的油液，定期檢查油液或成分，油箱容里應(yīng)為泵每分鐘流里的3 ~6倍等。要注意防止承受抽向力，否則會(huì)導(dǎo)致配油盤(pán)的早期磨損，引起壓力和效率的下降。力士樂(lè)葉片泵進(jìn)油管不得漏氣。那么在安裝、使用時(shí)要注意應(yīng)該要注意哪幾點(diǎn)呢?今天星興達(dá)液壓就來(lái)給大家說(shuō)一說(shuō)力士樂(lè)葉片泵進(jìn)油管不得扁氣在安裝使用時(shí)要注意應(yīng)該要注意如下:

　　一、對(duì)力士樂(lè)葉片泵的要求

　　1、力士樂(lè)葉片泵的轉(zhuǎn)速要求較高，當(dāng)轉(zhuǎn)速過(guò)低啟動(dòng)時(shí)，力士樂(lè)葉 片泵不能緊貼定子內(nèi)表面，壓力建立不起來(lái)，轉(zhuǎn)速過(guò)高會(huì)造成泵吸油不足而產(chǎn)生吸空現(xiàn)象。

　　2、力士樂(lè)葉片泵的抗污染能力比齒輪泵差。為此，進(jìn)油路濾油器精度設(shè)為308mum。二、力士樂(lè)葉片泵與力士樂(lè)葉片馬達(dá)故障與排除泵不出油，壓力表顯示沒(méi)有壓力1、油箱液面過(guò)低:向油箱內(nèi)加液壓油。2、吸油管或?yàn)V油器污物堵塞:清除污物。

　　3、吸油腔部分(油封，泵體吸油管接頭)漏氣:吸油腔是否有砂眼或氣孔，有則更換泵體。吸油管是否有裂縫，管接頭螺母是否擰緊，油封密封性能及質(zhì)里。

　　4、葉片在轉(zhuǎn)子槽內(nèi)被卡住，根本拋不出來(lái)，或者葉片折斷，葉片折斷造成高、低壓腔形成互通。葉片與槽配合過(guò)緊應(yīng)為滑動(dòng)配合，其配合間隙為0.0150.02m，并應(yīng)去毛刺。

　　5、配油盤(pán)缺損及配油盤(pán)與泵體接觸不良，造成密封區(qū)域被溝通，配油蓋側(cè)面有微小變形，修整配油盤(pán)與轉(zhuǎn)子的接觸面。

　　6、電機(jī)反轉(zhuǎn):將電機(jī)反向旋轉(zhuǎn)。

　　7、油液粘度過(guò)大:改用適當(dāng)粘度的油液。

　　8、未裝連接器或花鍵軸不轉(zhuǎn)或花鍵軸扭斷等:裝上連接鍵，更換花鍵軸。

　　9、吸油管過(guò)長(zhǎng):使泵靠近油箱，即相應(yīng)縮短了進(jìn)油管的長(zhǎng)度。

　　10、泵體質(zhì)里(砂眼、氣孔等):調(diào)換新泵體。

　　11、泵的轉(zhuǎn)速太低:調(diào)整轉(zhuǎn)速更換電機(jī)。
