1、重慶升降機液壓系統出現故障時(shí)也能導致液壓貨梯運行時(shí)噪音變大，設備在維修液壓系統后液壓泵、馬達、閥門(mén)及液壓安裝固定存在問(wèn)題容易引起震動(dòng)產(chǎn)生較大噪音，還有可能是液壓貨梯液壓缸內產(chǎn)生噪音，液壓油時(shí)，由于操作失誤，導致液壓缸內有空氣，在高壓作用下，容易產(chǎn)生氣穴現象，產(chǎn)生高頻噪音。
Hangzhou freight elevator hydraulic system failure can lead to hydraulic freight elevators running noise becomes large equipment hydraulic system after repair hydraulic pumps, motors, valves and hydraulic mounting problems likely to cause greater vibration noise, there may be a hydraulic freight elevator noise hydraulic cylinder, hydraulic oil, due to operational errors, leading to the hydraulic cylinder with air, under high pressure, prone to cavitation, to produce high-frequency noise.    
 
2、貨梯機械系統、油缸、液壓泵、液壓閥和管路問(wèn)題?？赡苁请妱?dòng)機轉子彎曲、磨損嚴重或軸承損壞，導致電動(dòng)馬達掃膛，產(chǎn)生噪音，可能是流接觸器產(chǎn)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(huán)折斷、磁軛與銜鐵的接觸面歪斜、有灰塵或生銹接觸不好時(shí)都會(huì )導致接觸器產(chǎn)生的噪音。
Hangzhou freight elevator mechanical systems, cylinders, hydraulic pumps, hydraulic valves and piping problems. Motor rotor may be bent, badly worn or bearing damage, resulting in electric motors sweep chamber, noise may be generated by high noise flow contact. When the supply voltage is less than 85% of rated voltage, short contact E-shaped core of the ring to break the yoke of skewed armature contact surface, dust or rust will cause poor contact contact noise generated.
     
3、貨梯電動(dòng)馬達、交流接觸器或電磁換向閥也會(huì )引起液壓貨梯產(chǎn)生高噪音。
Hangzhou freight elevators electric motors, AC contactor or solenoid valve can cause high noise generated hydraulic freight elevators.
