升降平臺廠家介紹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。下面濟南天銳升降機械的專家給大家詳細分析一下引起這種現象的主要原因是什么？
1、升降平臺廠家談到升降機液壓系統出現故障時也能導致升降機運行時聲音變大。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。更換升降機液壓油時，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。
When it comes to lift manufacturers can lead to lift operation sound bigger also lifts the hydraulic system failure. May be in the maintenance of hydraulic lifting platform hydraulic system pump, motor, valve and hydraulic mounting problems easy to cause vibration and high noise, there may be noise of hydraulic cylinder. When replacing the hydraulic elevator oil, due to operational errors, resulting in hydraulic cylinder in the air, under high pressure, easy to produce cavitation, resulting in high frequency noise.
2、升降平臺廠家再就是機械系統、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。當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。
Elevator manufacturers is mechanical system, an oil cylinder, a hydraulic pump, hydraulic valve and pipeline problem is motor rotor bending, severe wear or damage to the bearings, resulting in electric motor sweep chamber, noise, there may be AC contactor to produce high noise. When the supply voltage is below the rated voltage of 85%, contactor E-shaped iron core short-circuit broken ring, skew of contact surface of magnetic yoke and an armature, dusty or rust bad contact will cause buzzing noise of contactor.
3、升降平臺廠家提醒大家電動馬達、交流接觸器或電磁換向閥也會引起升降機產生高噪音。
Elevator manufacturers remind you electric motor, AC contactor or solenoid valve will cause high lift noise.
