良工閥門的動態平衡點在哪?

近年來,人們在選擇控制閥時一直在考慮一些傳統因素,如壓力額定值、壓降、流動介質、溫度和成本等。然而,在過去的10年里,情況發生了很大的變化,良工閥門設計取得了很大的進展,生產過程的成本效益特性與以往大不相同,大大削弱了許多傳統因素在選擇閥門時必須考慮的重要性。
In recent years, people have been considering some traditional factors when choosing control valves, such as pressure rating, pressure drop, flow medium, temperature, and cost. However, in the past 10 years, the situation has undergone significant changes, with great progress made in the design of Lianggong valves. The cost-effectiveness characteristics of the production process are greatly different from before, greatly weakening the importance of many traditional factors that must be considered when selecting valves.
雖然一些傳統因素仍然很重要,但它們只關注良工閥門“靜態"性能。事實上,他們在這里。“工作臺"閥門測量的結果很難說明閥門在實際運行條件下會表現出什么樣的性能。傳統理論認為,仔細調整靜態因素會使閥門(從而使整個電路)獲得良好的性能。然而,現在我們意識到情況并不總是如此。
Although some traditional factors are still important, they only focus on the "static" performance of high-quality valves. In fact, they are here. The results of "workbench" valve measurements are difficult to explain what kind of performance the valve will exhibit under actual operating conditions. Traditional theory suggests that carefully adjusting static factors can achieve good performance of the valve (and thus the entire circuit). However, now we realize that this is not always the case.

研究人員和制造商進行的成千上萬次性能檢查證明,多達50%的閥門(其中許多是通過考慮傳統因素選擇的)對優化控制電路的性能沒有太大影響。后續研究表明,閥門的動態特性在降低工藝變性方面發揮著重要作用。在許多關鍵過程中,即使不同良工閥門降低工藝變性的幅度相差1%,也能大大提高生產效率,減少廢物,從而達到100多萬美元的經濟效益。顯然,這種經濟效益使我們能夠完全否認傳統的做法,即只根據閥門的初始購買價格來決定是否購買。
Thousands of performance checks conducted by researchers and manufacturers have shown that up to 50% of valves, many of which were selected by considering traditional factors, have little impact on the performance of optimized control circuits. Subsequent studies have shown that the dynamic characteristics of valves play an important role in reducing process variability. In many key processes, even if the reduction of process variability varies by 1% among different skilled valves, it can greatly improve production efficiency, reduce waste, and achieve economic benefits of over $1 million. Obviously, this economic benefit enables us to completely deny the traditional practice of deciding whether to purchase based solely on the initial purchase price of the valve.
其次,傳統觀點總是認為,過程優化的改進總是來自于控制室控制儀器的升級。然而,測試數據表明,在使用相同控制儀器的情況下,閥門的動態特性對電路性能有顯著影響。
Secondly, the traditional view always holds that the improvement of process optimization always comes from the upgrading of control instruments in the control room. However, test data shows that the dynamic characteristics of the valve have a significant impact on circuit performance when using the same control instrument.
