液壓系統(tǒng)導(dǎo)致液壓泵過(guò)熱原因有:
一、液壓泵裝配不良導(dǎo)致液壓泵異常發(fā)熱:
①液壓泵中的間隙在選配時(shí)不合適(例如柱塞與缸體、葉片與轉(zhuǎn)子槽、定子與轉(zhuǎn)子、齒輪與側(cè)板等配合間隙過(guò)小等都會(huì)造成滑動(dòng)部位過(guò)熱燒傷)。
②液壓泵的裝配質(zhì)量差,傳動(dòng)部分同軸度沒(méi)有達(dá)到技術(shù)要求,在液壓泵運(yùn)轉(zhuǎn)的時(shí)候有別勁的現(xiàn)象怠敞糙緞孬等茬勸長(zhǎng)滑出現(xiàn)。
③液壓泵中軸承的質(zhì)量差或是在裝配的時(shí)候被打壞,或是在液壓泵安裝的時(shí)候沒(méi)有清洗干凈,造成液壓泵在運(yùn)轉(zhuǎn)時(shí)別勁。
④經(jīng)過(guò)軸承的潤(rùn)滑油排油口不暢通:由于回油口螺塞未打開(kāi)(未接管子),或是在安裝的時(shí)候通油道沒(méi)有清洗干凈,導(dǎo)致有臟物緒住油口,還有可能是由于在安裝時(shí)回油管彎頭太多或有壓扁的現(xiàn)象,導(dǎo)致排油口不通暢。
