中文摘要 | 評估染機流體動力效應的地方通常有兩個;即染液幫浦出口及嘖嘴處,但無論是筒子紗染機或批次式染布機的設備環境中限制很多,找不到合適的位置作為流量之量取點,例如;距幫浦出口處最少5倍管徑的限制、不可離彎頭太近、管徑變化處會產生紊流、溫度變化也會影響其精度等問題。 基於此,本文提出的三點式的壓差流量測定法沒有上述之限制,是最適合染布機的一種實用測量法,以「白努利能量不減定律」及「連續流體方程式」[1]為理論根據,計算出水頭抑損、管路壓差及流體速度等多項參數,進而換算成測量點流量的壓差式測定法。 |
英文摘要 | In nowdays, the flow measuring points in the dye-machine in which to estimate the dynamics effect were pump outlet and nozzle. Because of the limitation of the environment, despite of batch dye-machines as well yarn dye-machines, such as: at least 5 times distances superior to the diameter of pump outlet, away from the bend and variety in the pipes which was easy to cause un steady state flow. According to the proposition, we promote a useful measuring method that applicate the theory of the 「benoulli equation」and 「continuous equation」 to calculate the pressure loss, differential pressure and the velocity of the flow in the dye-machine flow system in order to transpose into flow datas so call 「tripoints detection」 |
