1、濟南升降貨梯http://www.38jp.cn/產生噪音的原因與液壓泵站、馬達、閥門等是否固定相關，檢查是否因為他們震動產生的噪音。
Jinan cargo lifter noise causes and pump stations, motors, valves, etc. are fixed-related, check whether the noise generated because of their shock.

2、濟南升降貨梯在更換液壓油的時候，有時候比較差的液壓油也會導致液壓升降貨梯有噪音，還有泵站進去空氣，也會產生噪音的現象。
Jinan cargo lifter when the hydraulic oil is changed, sometimes relatively poor hydraulic lift hydraulic oil will lead to a noisy freight elevators, as well as pumping stations into the air, will produce the phenomenon of noise.

3、濟南升降貨梯的溢流閥也能產生高噪音。當出現液壓油中混入空氣、溢流閥卡住或磨損嚴重、溢流閥的彈簧疲勞變形導致溢流閥調壓不穩定、溢流閥卸壓時間過短等狀 況時，容易導致溢流閥的先導閥性能部分穩定，在先導閥內引起空氣振動而產生噪音。
Jinan cargo lifter relief valve can also produce high noise. When the hydraulic oil mixed with air relief valve stuck or badly worn, the relief valve spring fatigue deformation leads to instability relief valve regulator, relief relief situation when time is too short, easily lead to relief the pilot valve performance partially stabilized, and produce noise-induced vibrations in the air the pilot valve.

4、濟南升降貨梯http://www.38jp.cn/液壓油不足時，液壓泵會產生吸空現象，導致空氣進入液壓油中，也會產生高噪音。
Jinan Huoti insufficient hydraulic oil, hydraulic pump will produce cavitation phenomenon, causing air into the hydraulic oil, will produce high noise.
