ddkm, something is definitely wrong here. With the pressures and volumes stated, there is nowhere it fits on the pump curve. This may be due to several reasons. Is it the correct curve ? Any reduction on the impeller size ? Any reduction on the number of impellers ? Are the gauges reading...
The pumps being discussed are centrifugal pumps handling hydrocarbon liquid (and of course entained gases. The coupling are interference fitted and the manufacturer said can be removed by heat. The environment requires that no flamable/explosive situation is allowed, and as such a flame heating...
Could anyone recommend a heating device (maybe a jacket, belt, etc, and its manufacturer) for the removal of pump coupling that was installed by interference.
The first challnge is that the removal will be in the vicinity of highly flamable fluids/gas. The second challenge is that removal...
Gents,
Does anyone have ideas on how to carry out pump efficiency tests for pumps in parallel and in operation, without having to stop any one of the other pumps that are not on test (centrigugal pumps and recips as well).
What are the consequences of "no-flow" tests while in...
Gents,
We are currently running up a gas turbine that came down on load - about 2.8MW, but it has refused to start. The last time it got to about 50% speed and tripped on high temperature. The control was confirmed ok, but could not decipher what could be wrong. Someone suggested compression...
