In the case where not installing rotor, a Bengtly9200 bearing chamber vibration is installed in bearing chamber vibration measurement position
Sensor and bearing bore diameter are installed a Bengtly9200 bear vibration sensor and are separately mounted on bearing chamber and bearing, benefit
Vibrational excitation is carried out to bearing with vibration excitation device, in the case where being stepped up vibrational excitation energy；
The vibration of bearing chamber is demarcated while the vibration of bearing reaches the alarming value and shutdown value that can cause equipment damage
Dynamic data, obtained bearing chamber vibration data.
Further, the vibration excitation device carries out vibrational energy control and vibration frequency control to rotating machinery bearing
System.
The utility model by exciting bank simulate the running Vibration Condition of rotating machinery, while record bear vibration and
Bearing chamber vibration, and compare.Bearing chamber evaluation of vibration axis can be passed through by comparative situation before in equipment operation
Hold vibration and equipment holistic health situation.The utility model can measure the amplitude and vibration velocity of bearing and bearing chamber simultaneously.

Specific embodiment
A kind of this practical New type rotary equipment bearing room vibration examination value calibration facility is described in detail with reference to the accompanying drawing
Preferred embodiment.
As shown in Figure 1, a kind of rotating machinery bearing chamber vibrates examination value calibration facility, by generation Ao's JZK series vibrational excitation
Device 2, Bengtly9200 bearing chamber vibrating sensor 3, Bengtly9200 bear vibration sensor 5, the acquisition of NI4432 data
Instrument, the sk4432 vibration analysis software evaluated the operation health condition of bear vibration and equipment form；
In the case where not installing rotor, a Bengtly9200 bearing chamber vibration is installed in bearing chamber vibration measurement position
Sensor 3 and bearing bore diameter install a Bengtly9200 bear vibration sensor 5 and are separately mounted to bearing chamber 4 and bearing 1
On, vibrational excitation is carried out to bearing using vibration excitation device 2, in the case where being stepped up vibrational excitation energy；
Bearing chamber 4 is demarcated while the vibration of bearing 1 reaches the alarming value and shutdown value that can cause equipment damage
Vibration data, obtained bearing chamber vibration data.
Vibration excitation device 2 carries out vibrational energy control and vibration frequency control to rotating machinery bearing.
The amplitude and vibration velocity of bearing and bearing chamber can be measured simultaneously.
The above are merely preferred embodiments of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection scope of utility model.
