Repair and Dynamic Balancing of IHI Lance Compressor Pinion Shaft Assembly

Blog on Repair and Dynamic Balancing of IHI Lance Compressor Rotor Assembly by Rokade Group

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.

They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller. This kinetic energy is then converted to an increase in potential energy/static pressure by slowing the flow through a diffuser. The pressure rise in the impeller is in most cases almost equal to the rise in the diffuser.

Dynamic balancing as per IS1940/1 at Grade G1

Repair & dynamic balancing of ihi lance compressor pinion shaft assembly

Diameter- 150 mm

Weight- 21 kg

Speed - 3000 RPM

Scope Of Work

On receipt of job at our Works we have done the initial inspection of shaft.

After cleaning we have done the PMI test for checking the material composition.

After understanding the material composition, we have done the welding procedure to built-up of the damaged portion on the shaft, followed by threading is done by machining process.

After Machining process, we have assembled the Pinion Shaft (low speed) with 1st Stage Impeller and checked Run out of this assembly followed by Dynamic balancing process carried out.
