Commissioning & Testing
1. High Speed Dynamic Balance Test
Gradually balancing from low speed to high speed.
The equilibrium speed is as close as possible to the critical speed.
Balance at rated working speed to ensure balance accuracy.
2. Rotor Test
The wheel rotation fracture test is carried out without damage in the ground with 122% maximum rotational speed.
Working on the engine at 115% maximum allowable steady-state operating speed for 5 minutes without cracking and the size is within the allowable range.
On the engine, exceed the maximum allowable average steady-state temperature of 42℃, work for 5 minutes without cracking, and the size is within the allowable range.
3. Vibration Test
20% margin between critical speed and maximum working speed.
During the test of the components and the whole machine, there is no adverse reaction to the vibration in the working speed rang
4. Performance, Characteristic Test
Performance tests under design conditions.
Characteristic tests under non-design conditions.
Process the test data to determine whether the performance of the component is up to standard and draw a characteristic curve.
