　　檢查與排除方法：
　　(1)在主回路安全閥、過載閥和其他附件完好的前提下,將進油管與馬達接口封死(不得漏油),在馬達正、反轉(zhuǎn)時測定供油油路的大壓力；力耐通液壓馬達為您傳遞高效液壓能量,然后接通馬達管路,測定有負載時壓力；后將測定值與其技術要求相比較即可判定故障部位.
　　(2)因為液壓泵流量不足或壓力低均會使馬達輸出功率下降、轉(zhuǎn)矩和轉(zhuǎn)速同時降低,因此測定流量應與測定壓力同步進行.
　　(3)檢查配流軸和轉(zhuǎn)子孔的間隙是否在允許范圍內(nèi)(見附表),檢查配流軸和缸體孔的旋轉(zhuǎn)中心線是否一致,如超出允許值應重新裝配.若出現(xiàn)配流軸與轉(zhuǎn)子孔的配合間隙超過0.6mm,或轉(zhuǎn)子內(nèi)配流孔沿周向出現(xiàn)拉槽；柱塞與轉(zhuǎn)子配合間隙超過0.05mm,滾輪方軸與滑槽配合間隙超過0.05mm時,均會使低速大扭矩內(nèi)曲線馬達轉(zhuǎn)動無力.力耐通液壓馬達為您傳遞高效液壓能量若兩只行走馬達不同步,則將使履帶跑偏.
　　(4)斜盤式軸向柱塞馬達,經(jīng)長期高速運轉(zhuǎn),馬達輸出軸支承軸承間隙會增大,軸向定位間隙超過碟形大彈簧補償值；缸體(轉(zhuǎn)子)與配流盤問由于中心定位桿上4片碟形彈簧不能正常地將轉(zhuǎn)子缸壓向配流盤(碟簧疲勞強度降低,彈力下降時,在冷態(tài)下馬達能正常運轉(zhuǎn),熱態(tài)下碟簧變形會加大),導致配流能力下降,造成馬達運轉(zhuǎn)無力.當轉(zhuǎn)子與缸孔間隙超過0.05mm,或磨損超過正常值時,均會引起馬達無力和運轉(zhuǎn)緩慢.
　　2、泄漏
　　原因可能是：配流盤(配流孔)磨損或拉傷,柱塞孔和柱塞磨損,使高低壓腔間密封不良,工作腔難以形成高壓,導致進油量不足；泄漏量與馬達進出口壓差、油黏度、排量和配流結(jié)構(gòu)及加工裝配質(zhì)量等有關,泄漏量不穩(wěn)定會引起馬達轉(zhuǎn)速不穩(wěn)、抖動或時轉(zhuǎn)時停；泄油管路回油不暢,促進低壓油壓力提高,導致骨架油封密封效果下降,使油液從馬達輸出軸端向減速器殼(或制動器內(nèi))泄漏；馬達輸出軸支承軸承損壞,會產(chǎn)生偏心泄漏、異響；內(nèi)泄將引起馬達閉鎖制動性能下降,不能準確地停在某一位置,會使挖掘機產(chǎn)生滑移,極不安全.
　　檢查與排除方法是：檢查配油軸或缸體孔內(nèi)表面是否劃傷,先清洗,嚴重者應更換；檢查柱塞和柱塞孔配合面時若有拉毛、溝槽,研磨、拋光配合面后再配磨,嚴重者更換；檢查柱塞和柱塞孔配合面間隙是否太大(一般應為柱塞直徑的8‰以內(nèi)),必要時更換；力耐通液壓馬達為您傳遞高效液壓能量高速馬達內(nèi)泄漏,可通過拆檢馬達泄油管,在空轉(zhuǎn)和負載時分別測定殼體單位時間漏油量以確定故障程度.
