成都升降机作为一种重要的高空升降设备，具有广泛的用途，在我们从事升降机的销售和售后服务中，有客户反映升降机工作时噪声过大。为了解决这一问题，下面根据我们的工作经验，为大家总结一下成都升降机工作时噪声大的原因。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.成都升降机液压系统出现故障时也能导致升降平台运行时声音变大。可能是升降平台在维修液压系统后液压泵、马达、阀门及液压安装固定存在问题容易引起震动产生较大噪音，还有可能是液压缸内产生噪音。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.

更換东莞升降货梯机气动系统油时，根据操控犯错，致使气动系统缸内空着气，在高压电用下，便捷发生气穴症状，发生低频躁声。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.成都升降机机械系统、油缸、液压泵、液压阀和管路问题。可能是电动机转子弯曲、磨损严重或轴承损坏，导致电动马达扫膛，产生噪音，还有可能是流接触器产生高噪声。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.

伪装成都升降架机电源模块电流值大于额定的电流值的85%、接处器E形铁芯的不导通环扯断、磁轭与衔铁的接处面倾斜、有脏污或上锈接处差时都可以影响接处器有"轰轰"的噪声。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.电动四轮启动马达、交谈沾染器或涡流换相阀也会给予上海举升机带来高解决。Electric motors, AC contactor or solenoid directional valve can also cause high noise in Chengdu lift.
