Bently Nevada公司生产的监测保护系统主要用于大型旋转和往复机械的机体振动监测和保护。本特利振动测量系统应用于我们的空气压缩机和氧气压缩机系统。由于超速是汽轮机组极其危险的情况之一，必须安装超速保护系统。宾利公司开发了由电涡流传感器和超速保护监控器组成的电子超速监控系统，是完整超速保护系统的一部分。我们的振动测量系统使用3300和3500振动测量系统。这一次，我们重点介绍用于23500制氧机的3500振动测量系统。

The monitoring and protection system produced by Bently Nevada company is mainly used in the monitoring and protection of body vibration of large rotating and reciprocating machinery. Bently vibration measurement system is applied in our air compressor and oxygen compressor system. Because overspeed is one of the extremely dangerous situations for turbine unit, overspeed protection system must be installed. Bentley company has developed an electronic overspeed monitoring system composed of eddy current sensor and overspeed protection monitor, which is a part of the complete overspeed protection system. There are 3300 and 3500 vibration measurement systems used in our vibration measurement system. This time, we focus on the 3500 vibration measurement system used in 23500 oxygen generator.


 

Bentley 3500 system is used for vibration monitoring and protection of large machinery. Bentley 3500 system must be equipped with frame 3500/05, power 3500/15, frame interface module 3500/22m,
