當(dāng)我們聽到升降機(jī)有噪音時(shí)，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。 如果在更換液壓油的時(shí)候，因?yàn)椴僮鞯牟恢?jǐn)慎，會(huì)導(dǎo)致液壓缸中進(jìn)入空氣，當(dāng)升降機(jī)有高壓時(shí)會(huì)產(chǎn)生氣穴，使液壓缸產(chǎn)生噪音。
When we hear the noise of the elevator, the first to check the valve, motor, hydraulic pump, a fixed installation and other aspects of the factors leading to noise generation. If the replacement of hydraulic oil, because the operation is not careful, will cause the air into the hydraulic cylinder, when the lift high pressure will produce cavitation, the noise produced by the hydraulic cylinder.
使用新的密封圈或者密封過緊，也會(huì)產(chǎn)生大的噪音，不過磨合一段時(shí)間就沒有問題了。液壓油不足時(shí)，液壓泵產(chǎn)生吸空，將空氣吸入到液壓油中，這樣也會(huì)導(dǎo)致液壓升降機(jī)高噪音的產(chǎn)生。
Elevator manufacturers analysis with a new sealing ring or seal tight, will also have a big noise, but in a period of time there is no problem. When the hydraulic oil is not enough, the hydraulic pump has suction, and the air is sucked into the hydraulic oil, which can cause the high noise of the hydraulic lift.
如果液壓油吸入空氣或者溢流閥卡住，或升降機(jī)磨損比較嚴(yán)重時(shí)，會(huì)引起溢流閥調(diào)壓不穩(wěn)以及卸壓時(shí)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。
If the elevator manufacturers analysis of hydraulic oil or air relief valve stuck, or 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.
