不同形式複數台離心式流體機械並聯之最佳化研究

Abstract

本文主要目的為採用多台不同型式之離心式流體機械的並聯方式，進行複雜管路流量計算。對於複雜管路系統，單台離心式流體機械往往無法提供龐大的流量需求，必須採用多台並聯的方式處理，故要找出不同形式離心式流體機械並聯且完整計算且將效率曲線隨轉速變化之公式求出，並將效率曲線併入模擬的計算過程中，求得每台離心式流體機械的效率值，進而計算出系統所需的總功率，從不同的並聯台數及不同的流體機械形式並聯找出最省能之並聯方式。

In order to provide huge mass flow rate, the centrifugal machineries in parallel are necessary. However, the problem mentioned above is hardly studied. The aim of this study is to solve the complex piping problems and obtain the optimal situation with the differences of centrifugal machineries in parallel. The equation of the efficiency curve varied with the rotation rate is formulated. The efficiency of each centrifugal fluid machines in any rotation rate can be count rotation rate, and then the used power of the system will be obtain. The optimal operation choice of different numbers of the parallel fluid machineries will be defined.
