Compressor Crankshaft Grinding and Polishing Onsite

RA Power Solutions was approached by a leading Fertilizer producing company based in north India regarding the requirement of onsite grinding and polishing of compressor crankshaft.

The company has five high-capacity CO2 compressors which have been imported from a leading company based in Europe.

Our team consisting of three technicians along with onsite crankshaft grinding equipment was deputed to the site and following was observed:

Details of CO2 Compressor Crankshaft:

S. NO	Crankshaft Details
1	Engine Make/ Model	CO2 COMPRESSOR
2	Crankpin Diameter Standard	317.30 MM
3	Crankpin Bearing Width	210.00 MM
4	Main Journal diameter	330 mm & 317.30 mm
5	Main Journal Width	370 mm & 225 mm
6	Place of execution of crankshaft repair	Fertilizers & Chemicals Plant in India

On dimensional inspection of crankpin it was observed that crankpin nos. 02 developed excessive ovality. It also had deep line marks due to the failure of bearings which are of babbitt white metal type.
All the remaining crankpins were inspected and rough surfaces including bearing line marks were observed.
The main journal having a standard diameter of 330 mm also had a rough surface and required polishing.

Action taken by RA Power Solutions

Considering the fact that the main journal having a diameter of 330 mm having a rough surface and bearing line marks it was decided to remove the crankshaft from the compressor.

RA Power Solutions technicians submitted a drawing of V-Block which were manufactured in the factory for placement of crankshaft.

The grinding of crankpin no. 02 was undertaken and the final dimensions were maintained between 315.58 mm to 315.60 mm. The ovality of only 0.02 mm was observed.

All the remaining 05 crankpins were polished, removing the line marks and improving the surface finish. The surface finish after polishing was observed at less than 15 RA value.

All the main journals were also polished onsite removing the ovality to some extent and improving the surface finish again to less than 15 RA value.

Repair of MAN B&W Model 5L 16-24 by Using Onsite Crankshaft Grinding Machine

MAN Engine Model no. 5L 16/24 is a very common installation on vessels and the engine is used as Generator. The Crank Pin diameter of MAN Engine Model no. 5L 16/24 is only 130mm and the bearing width is 56 mm. In other words, it is about 2 inches

This makes the onsite crankshaft repair very difficult due to limited space in between the two webs. Most onsite crankshaft repair companies based in Europe don’t have the equipment and the technology to undertake grinding/ repair of crankpin of MAN Engine Model no 5L 16/24. The repair companies always suggest to remove it from the engine block and send it to workshop for crank pin grinding or reject the crankshaft.

We successfully executed the repair of the crankshaft of MAN Engine Model no. 5L 16/24. Details are as mentioned below:

S. NO	Crankshaft Details
1	Engine Make	MAN B&W
2	Engine Model	5L 16/24
3	Crank pin Diameter Standard	130 mm
4	Crankpin Bearing Width	56 mm
5	Place of execution of crankshaft repair	Port of Castellon Spain

Details of Crankshaft repair job executed by RA Power Solutions technicians at a port of Castellon Spain.

The damaged crankpin was checked for taper & ovality and it was observed 0.49 mm.
Deep bearing line marks were observed.
All other parameters like hardness and crack detection by MPI were checked and no abnormality was found.
The crankpin was ground to an undersize of 1.0mm.

Supply of Undersize Bearing for MAN Engine Model No. 5L 16/24

It is obvious that whenever grinding is undertaken there is requirement of undersize bearing. In this case of MAN Engine Model no. 5L 16/24, RA Power Solutions arranged and supplied 1.0 mm undersize crankpin bearing to the client.

We maintain a large stock of standard & undersize bearings of crankpin & main journal of popular make & model of engines like Yanmar, Daihatsu, MAK and MAN B&W, etc.

The Engine was commissioned in presence of our technicians and performance was found to be satisfactory.
