济南升降货梯为什么会产生噪音？

1、济南升降货梯http://www.jntr168.com/产生噪音的原因与液压泵站、马达、阀门等是否固定相关，检查是否因为他们震动产生的噪音。
Jinan cargo lifter noise causes and pump stations, motors, valves, etc. are fixed-related, check whether the noise generated because of their shock.

2、济南升降货梯在更换液压油的时候，有时候比较差的液压油也会导致液压升降货梯有噪音，还有泵站进去空气，也会产生噪音的现象。
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、济南升降货梯的溢流阀也能产生高噪音。当出现液压油中混入空气、溢流阀卡住或磨损严重、溢流阀的弹簧疲劳变形导致溢流阀调压不稳定、溢流阀卸压时间过短等状 况时，容易导致溢流阀的先导阀性能部分稳定，在先导阀内引起空气振动而产生噪音。
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、济南升降货梯http://www.jntr168.com/液压油不足时，液压泵会产生吸空现象，导致空气进入液压油中，也会产生高噪音。
Jinan Huoti insufficient hydraulic oil, hydraulic pump will produce cavitation phenomenon, causing air into the hydraulic oil, will produce high noise.
