要注意(yì)液壓升(sheng)降機氣(qi)蝕和溢(yì)流噪聲(shēng)，液壓升(sheng)降機作(zuo)業中要(yao)時刻注(zhu)意液壓(yā)泵和溢(yì)流閥的(de)聲音，如(rú)果液壓(yā)泵出現(xian)“氣蝕”噪(zao)聲，經排(pai)氣後不(bú)能消除(chu)，應查明(ming)原因排(pai)除故障(zhang)後才能(neng)使用。如(ru)果液壓(ya)升降機(ji)某執行(hang)元件在(zai)沒有負(fù)荷時動(dòng)作緩慢(màn)，并伴有(you)溢流閥(fa)溢流聲(shēng)響，應立(lì)即停機(ji)檢修。操(cao)作手要(yào)保持穩(wen)定，因為(wéi)每台設(shè)備操縱(zong)系統的(de)自由間(jiān)隙都✌️有(yǒu)一定差(chà)異，連接(jiē)部位的(de)磨損程(chéng)度不同(tóng)因而其(qí)間隙也(ye)不同，發(fa)動機及(ji)液壓系(xì)統出力(lì)🔞的大小(xiǎo)也不盡(jìn)相同。
Attention should be paid to the hydraulic lift and overflow cavitation noise, hydraulic lift operation should always pay attention to the hydraulic pump and overflow valve sound, if the hydraulic pump "cavitation" noise, the exhaust can not be eliminated, should be identified to cause after troubleshooting. If a hydraulic lift actuator does not move slowly when there is no load, accompanied by overflow valve overflow sound, should immediately stop maintenance. The operator should remain stable, because the free clearance per device control system there are some differences in the degree of wear, the connecting parts of the different so the gap is different, the size of the output of the engine and hydraulic system are not the same. 

隻(zhi)有使用(yòng)液壓升(sheng)降機的(de)操作手(shou)認真摸(mō)索，修正(zheng)自己的(de)操縱動(dòng)作以适(shì)應設🌈備(bèi)🍓的個性(xìng)，經過長(zhang)期作業(yè)後，才能(neng)養成符(fu)合設備(bei)個性的(de)良好操(cāo)作習慣(guàn)。一般機(jī)械行業(ye)堅持定(ding)人定機(ji)制度💰，這(zhe)也是因(yin)素之一(yi)。
Only the use of hydraulic lift operator carefully explore, modify their manipulation to adapt to the personality of the device, after long-term operations, in order to develop a good personality in line with the operating habits of

equipment. General machinery industry adhere to the fixed machine system, which is one of the factors.
