| Abstract: | In view of the original design and low operation efficiency， high power
consumption etc． problems existing in Czech-made CCV 125／13 type feedwater pumps in
Tangshan General Power Plant， the scheme on improving design parameters and overall
design was put forward． This article lays stress on introducing the design and
configuration improvements of flow passage components ，and analysing the testing results
and economic benefit of retrofit ．All the main performance parameters of feed water
pumps after retrofit could meet the design requirements with efficiency of 71．65％
gained． |
