簡單介紹一下力士樂:溶解在液壓油中的空氣,在通常壓力下,其影響可忽略不計,但在低壓狀態(tài)下,溶解空氣將會逸出,產(chǎn)生汽泡,形成汽穴現(xiàn)象,將會產(chǎn)生如下影響:
?。?)汽泡在低壓區(qū)急劇壓縮并破碎,使油溫過熱,產(chǎn)生噪聲,振動時使油液變質(zhì)。特別是因汽穴現(xiàn)象油液產(chǎn)生局部高溫后,油液氧化變質(zhì)加劇,降低使用壽命。
(2)因汽穴現(xiàn)象產(chǎn)生腐蝕及沖擊,使液壓元件很快受損,影響系統(tǒng)的可靠性、壽命等。
?。?)空氣的可壓縮性使工作裝置產(chǎn)生爬行,影響了工作的平穩(wěn)性。
