Industrial Centrifugal Type Gas Turbo Compressor
Product Description
The centrifugal compressor is a kind of air compression system
which is composed of lubrication system, PLC control system,
compressor body, impeller, gear system, bearings, import guide
vane, interstage cooler etc. It has advantages compared with piston
compressors like compact structure, large air flow, stable and
reliable, low maintenance costs.

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.
