1、觀察升降貨梯http://55506132.com/外表的不正常現(xiàn)象，漏油、沾污、郵箱油量及油液污濁情況；觀察油中的氣泡情況，可以判斷出系統(tǒng)進(jìn)氣的程度，進(jìn)而排除與系統(tǒng)進(jìn)氣有關(guān)的故障；觀察系統(tǒng)總回油管的回油情況，可以判斷出液壓泵工作是否正常，為排除系統(tǒng)故障提供重要參考。
Irregularities observed Huoti appearance, oil spills, stains, oil and oil polluted situation mailbox; bubbles were observed in the case of oil, can determine the extent of the intake system, and then exclude the intake system related failures; the case back to the oil return pipe of the total observation system can determine whether the pump is working properly, providing an important reference for troubleshooting the system.

2、用耳朵聽升降貨梯工作時(shí)的振動(dòng)、噪聲、不正常的響聲或抖動(dòng)，通過對各個(gè)部位進(jìn)行探聽，可直接找出噪聲產(chǎn)生的部位，探聽時(shí)通常采用一根細(xì)長的銅管，一般噪聲比較大、聲音清晰處就是噪聲產(chǎn)生的部位。
Listen with the ears of vibration cargo lifter at work, noise, abnormal sound or vibration, through the various parts of Snoop directly identify the parts of the noise generated, usually when a slender brass snoops, general noise is large parts of the sound is clear is that it is noise.

3、溫度不正常和振動(dòng)故障，通過用手摸的辦法即可找出故障部位，對于液壓泵和管道局部過熱故障采用手摸方法更為有效。
Abnormal temperature and vibration fault, you can find out the fault location by touching the way by hand, more efficient pumps and piping for the use of local overheating fault hand touch method.

4、聞一聞升降貨梯http://55506132.com/油液是否有異味變質(zhì)，油液嚴(yán)重變質(zhì)影響液壓系統(tǒng)的正常潤滑，必修換新油。
Smell is the smell of oil cargo lifter deterioration, oil serious deterioration affecting the normal lubrication of the hydraulic system, compulsory renewal of oil.
