當(dāng)我們聽到重慶升降平臺有噪音時，第一先要檢查閥門,、馬達(dá)、液壓泵,、固定安裝等方面的因素導(dǎo)致噪音產(chǎn)生。When we hear the noise of the Hangzhou landing platform, the first to check the valve, motor, hydraulic pump, fixed installation and other aspects of the factors leading to noise generation.

如果在更換液壓油的時候,，因為操作的不謹(jǐn)慎,，會導(dǎo)致液壓缸中進(jìn)入空氣，使液壓缸產(chǎn)生噪音,。使用新的密封圈或者密封過緊,，也會產(chǎn)生大的噪音，不過磨合一段時間就沒有問題了,。If the replacement of hydraulic oil, because the operation is not careful, will lead to the hydraulic cylinder into the air, so that the hydraulic cylinder noise. Use a new sealing ring or seal tight, will also have a big noise, but in a period of time there is no problem. 

液壓油不足時,，液壓泵產(chǎn)生吸空，將空氣吸入到液壓油中,，這樣也會導(dǎo)致重慶升降平臺高噪音的產(chǎn)生,。When the hydraulic oil is not enough, the hydraulic pump will be sucked out, and the air will be sucked into the hydraulic oil, which will lead to the generation of the high noise of the lifting platform in Hangzhou. 

液壓油吸入空氣或者溢流閥卡住，或液壓升降機磨損比較嚴(yán)重時,，會引起溢流閥調(diào)壓不穩(wěn)以及卸壓時間太短等問題,，這些問題間接導(dǎo)致溢流閥先導(dǎo)閥性能不穩(wěn)，導(dǎo)致噪音產(chǎn)生,。Hydraulic oil or air relief valve stuck, or hydraulic lift more serious wear, will cause the pressure relief valve adjustment is not steady and the unloading time is too short and other issues, these problems lead to indirect pilot valve relief valve performance instability, resulting in noise.
