Performance test and analysis of boiler feed water pumps before and after overhaul 給水泵大修前后性能試驗及分析
A test - bed of dg45 - 80 10 hypo - pressure feed water pump is designed , based on which the general on - line performance testing system is developed and the thermodynamic method is introduced to measure the efficiency of the pump . a new programming technology combining vc + + with matlab is presented by which the vibration monitoring system of boiler feed water pump is developed successfully to perform data analysis after on - line acquisition 本文首先進行了次高壓鍋爐給水泵dg45 80 10實驗臺的設(shè)計,在此實驗臺設(shè)計成功并安裝調(diào)試通過的基礎(chǔ)上,開發(fā)了鍋爐給水泵通用性能試驗系統(tǒng),包括測點的布置、各型測量儀器的選購,設(shè)計,安裝和調(diào)試以及軟件平臺開發(fā)。
