Here is one example of our analysis technology.
We have supplied low vibration pump for dead water intake pump in Jordan. The model was DF-VP(Pull out type) 1350mm×4950kW×4sets, 310.8m3/min×60m.

The highlight of this super sized pump is its length, with 27m from top to bottom. We made it long for the coming draw down of the Dead Sea water in the future. In fact the water level was 1.1m decreasing every year.
However our challenge was to avoid the risk of resonance phenomenon. As you can see in the picture below, we conducted vibration analysis in various patterns and finally came up to the most reliable shape.

Analysis of shape G001(First Shape)

Analysis of shape G007(The adopted shape)

We also conducted construction analysis to this pump.
We analyzed the valid and feasible position of reinforced rib against the external force. As a result, we were able to reduce the maximum stress and maximum deformation to more than 1/4 (one fours) compared to the first shape.

Example of Structural Analysis of casing

This is the picture of the four pumps installed on the dead water.
As the result of perfect analysis in several aspects, we were able to supply many kinds of pumps in difficult conditions all over the world.
