1、電動(dòng)馬達(dá)產(chǎn)生高噪音的原因主要有電動(dòng)機(jī)轉(zhuǎn)子彎曲、磨損嚴(yán)重或軸承損壞，導(dǎo)致電動(dòng)馬達(dá)掃膛，產(chǎn)生噪音；電動(dòng)馬達(dá)冷卻風(fēng)扇損壞或固定不牢固產(chǎn)生高噪音；電動(dòng)馬達(dá)固定不牢固，也能引起震動(dòng)，產(chǎn)生高噪音。
Lift manufacturers analysis of electric motors have a major reason for the high noise of a motor rotor bending, severe wear or bearing damage, resulting in electric motors sweep chamber, generating noise; an electric motor cooling fan is damaged or not firmly fixed to produce high noise; an electric motor is not firmly fixed, can cause vibration, resulting in high noise.

2、介紹交流接觸器也能產(chǎn)生高噪音，當(dāng)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(dǎo)致接觸器產(chǎn)生嗡嗡的噪音。
Lift manufacturers introduce AC contactors can also produce high noise, 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, there is no contact with dust or rust Hershey will result in contact produces a buzzing noise.

3、談到電磁換向閥電磁線圈固定不牢固，銜鐵頻繁的分開(kāi)和吸合也能產(chǎn)生高噪音。
Speaking solenoid valve lift manufacturers analysis is not firmly fixed solenoid armature frequent and pull apart can also produce high noise.
