How to Check Crankshaft Wab Deflection in reciprocating compressors

Why do we need to measure crankshaft deflection?

The weight of the crankshaft is supported by the bearings at the main journals. Additionally, crankshafts regularly endure huge forces and temperature changes. With extended use, the bearings will suffer some wear, which may not be uniform across the crankshaft. 

As such, the initial straight line of the crankshaft may get deformed, either upward or downwards. And while these deformations are usually invisible to the naked eye, they can cause dangerous deflections in the crankshaft webs. Due to metal fatigue, this could lead to damage within the engine. 

Regular boat maintenance helps engineers detect these misalignments in the bearings of the crankshaft and prevent failures of the component.

With that said, replacing the crankshaft isn't a benign intervention. It requires a full engine rebuild, and depending on the size of the vessel, it can take days, even weeks before it can be fully mended.

Moreover, the part itself is quite expensive and once again, this price will increase with the size of the ship. And the crankshaft failure itself can cause additional damage to internal parts of the engine, driving reparation costs through the roof. 

All in all, you should perform crankshaft deflection measurements regularly to prevent these extreme repair costs and detect signs of trouble early on.How to work crankshaft in Reciprocating compressorHow to work reciprocating compressorbike crankshaft balancingbike start sound problemconnecting rod solidworkscrankshaft solidworksgold rate in pakistan today gold priceinterview Question and answer crankshaftlearn solidworkspistonpiston solidworkspiston solidworks tutorialqasim ali shah lecturessolidworks trainingsolidworks tutorial for beginners
