產(chǎn)品中心
美國(guó)威格士產(chǎn)品詳解:
VICKERS柱塞泵過熱 液壓泵過度發(fā)熱有兩個(gè)原因,一是機(jī)械摩擦生熱。由于運(yùn)動(dòng)表面處于干摩擦或半干摩擦狀態(tài),運(yùn)動(dòng)部件相互摩擦生熱。二是液體摩擦生熱。高壓油通過各種縫隙泄漏到低壓腔,大量的液壓能損失轉(zhuǎn)為熱能。所以正確選擇運(yùn)動(dòng)部件之間的間隙、油箱容積和冷卻器,可以杜絕泵的過度發(fā)熱和油溫過高的現(xiàn)象。另外,回油過濾器堵塞造成回油背壓過高,也會(huì)引起油溫過高和泵體過熱。
7.漏油 柱塞泵漏油主要有以下原因:(1)主軸油封損壞或軸有缺陷、劃痕;(2)內(nèi)部泄漏過大,造成油封處壓力增大,而將油封損傷或沖出;(3)泄油管過細(xì)過長(zhǎng),使密封處漏油;(4)泵的外接油管松動(dòng),管接頭損傷,密封墊老化或產(chǎn)生裂紋;(5)變量調(diào)節(jié)機(jī)構(gòu)螺栓松動(dòng),密封破損;(6)鑄鐵泵殼有砂眼或焊接不良。
