This study aims to research and development for large diameter pipe flow generator. Its characteristics, with the Tunnel opening and sealing technology, it is a quickly and easy installation of sustainable power detection system. This paper reports two kinds of design development process:
Flexible shaft Design：
Flexible shaft is used to replace the hard shaft and gears, mechanical gears to reduce wear and energy loss between; and then with magnetic coupling one design, thereby improving the procedures for assembly, the volume reduced and the subsequent leakage concerns; shaft design for Too much friction with the shaft casing, causing the load of a join, the impeller can not continue to operate, so that power can’t achieve the basic conditions.
Short-hard shaft design：
Is a combination of flexible shaft of transmission design and the traditional advantages of using a single axis Chuandao media, but will power the whole system into the internal channels to increase system integration, increase reliability; after a short shaft design leaves the hard cross-matching and follow-up of iron Central to join, upgrade to the voltage from 0.46V 0.72V, dual impeller configuration and hoop to join, help to improve the generation and system stability.
