Rotating machinery such as turbines, generators, gas turbines, compressors, fans, pumps and others are key equipment in power supply, petrochemical, metallurgical industries. Vibration is a important factor as well as a "thermometer" which affect the safe operation of these rotating machinery, directly reflect the operation status of the equipment. Once rotating machinery had a fault, it will bring huge economic losses.
1WeiBao vibration analysis services can help you find the following problems

Object
|
Fault
|
|
Common Drive
|
Bearing alignment, imbalance, rotor eccentricity, shaft bending, mechanical loosening
|
|
AC Asynchronous Motor
|
Stator eccentricity, stator layer short circuit, loose core, rotor eccentricity, rotor abnormalities, phase anomaly
|
|
Geared motor
|
Wear to gear teeth, backlash eccentric and uneven, gear bearing alignment, tooth loss and fracture
|
|
Belt drive
|
Belt wear, loose, belt resonance, the rotor eccentricity
|
|
Fluid Vibration

State Analysis and fault diagnose:
|
Eccentricity of rotor
|
.jpg) |
1.Result in a straight line vibration along the two centered
2.Vibration frequency appears in the 1 × RPM
3.With vertical or horizontal phase bearing 180 ° or 90 °. |
|
Axis bending
|
.jpg) |
1.produce a large axial vibration
2.The phase difference between the two bearing is 180 °
|
|
Basis loose
|

1. 1 ×, 2 × rpm radial vibration is noticeable (normally 2 × vibrate obviously), there is also likely a smaller 3 × radial vibration.
2. There may only a large amplitude (vertical or horizontal) on the direction of loose part- the radial direction is much greater than the orthogonal. 3. It is easy to find the background vibration on the close surface. |
|
Bearing loose
|
 |
1.The radial harmonic vibration of 1 × is obvious.
2. When the loose is worse, the harmonics will be extended, even produce semi-harmonic in extreme cases (1.5, 2.5, 3.5, etc.) |
