成都升降機作為一種重要的高空升降設備，具有廣泛的用途，在我們從事升降機的銷售和售后服務中，有客戶反映升降機工作時噪聲過大。為了解決這一問題，下面根據我們的工作經驗，為大家總結一下成都升降機工作時噪聲大的原因。As one of the important lifting equipment, Chengdu elevator has a wide range of applications. In our sales and after sales service, customers have to reflect the noise of the elevator. In order to solve this problem, the following according to our work experience, summed up the reasons for the noise of the work of the Chengdu elevator.
 
1.成都升降機液壓系統出現故障時也能導致升降平臺運行時聲音變大。可能是升降平臺在維修液壓系統后液壓泵、馬達、閥門及液壓安裝固定存在問題容易引起震動產生較大噪音，還有可能是液壓缸內產生噪音。Chengdu elevator hydraulic system failure can also cause the lifting platform to run when the sound becomes large. May be the lifting platform in the maintenance of hydraulic systems, hydraulic pumps, motors, valves and hydraulic installation and fixed problems are likely to cause greater noise vibration, there may be noise in the hydraulic cylinder.

更換成都升降機液壓油時，由于操作失誤，導致液壓缸內有空氣，在高壓作用下，容易產生氣穴現象，產生高頻噪音。Chengdu elevator replacement of hydraulic oil, due to operational errors, resulting in air hydraulic cylinder, under high pressure, prone to cavitation, produce high frequency noise.

2.成都升降機機械系統、油缸、液壓泵、液壓閥和管路問題。可能是電動機轉子彎曲、磨損嚴重或軸承損壞，導致電動馬達掃膛，產生噪音，還有可能是流接觸器產生高噪聲。Chengdu elevator mechanical system, oil cylinder, hydraulic pump, hydraulic valve and pipeline. May be the motor rotor bending, wear serious or bearing damage, resulting in electric motor swept bore, noise, there may be a high noise flow contactor.

當成都升降機電源電壓低于額定電壓的85%、接觸器E形鐵芯的短路環折斷、磁軛與銜鐵的接觸面歪斜、有灰塵或生銹接觸不好時都會導致接觸器產生"嗡嗡"的噪音。When Chengdu elevator power supply voltage is lower than the rated voltage of the contactor 85%, E core short-circuit ring broken, magnetic yoke and armature contact surface deflection, dust or rust will lead to bad contact contactor have a "buzzing" noise.

3.電動馬達、交流接觸器或電磁換向閥也會引起成都升降機產生高噪音。Electric motors, AC contactor or solenoid directional valve can also cause high noise in Chengdu lift.
