1、重慶貨梯液壓油變質(zhì)或有雜質(zhì)，液壓油長(zhǎng)時(shí)間利用后，液壓油內(nèi)大概有雜質(zhì)或已變質(zhì)，取樣舉行查抄，看是否含流體顆粒物、變色、變臭，須要時(shí)要改換液壓油。
Hangzhou cargo elevator hydraulic oil deterioration or impurities, after a long time of use of hydraulic oil, the hydraulic oil is probably a matter of impurities or has gone bad, sampling inspection, to see whether the fluid particles,color, change, need to change the hydraulic oil.

2、杭州貨梯液壓泵也是影響液壓油流量的關(guān)鍵因素，液壓泵在經(jīng)過(guò)長(zhǎng)久使用之后，會(huì)容易引起磨損，杭州貨梯速率變慢時(shí)，應(yīng)查抄液壓泵供油流量是否不變，若現(xiàn)磨損及時(shí)與廠(chǎng)家聯(lián)絡(luò)，以避免過(guò)保修期。
Hangzhou cargo ladder hydraulic pump is also a key factor affecting the flow of hydraulic oil, hydraulic pump in a long period of use, will easily lead to wear and tear, Hangzhou cargo flow rate is slow, should check the hydraulic pump flow is constant, if the current wear and manufacturers to contact, in order to avoid the repair period.
