良工閥門的動(dòng)態(tài)平衡點(diǎn)在哪?

近年來(lái),人們?cè)谶x擇控制閥時(shí)一直在考慮一些傳統(tǒng)因素,如壓力額定值、壓降、流動(dòng)介質(zhì)、溫度和成本等。然而,在過(guò)去的10年里,情況發(fā)生了很大的變化,良工閥門設(shè)計(jì)取得了很大的進(jìn)展,生產(chǎn)過(guò)程的成本效益特性與以往大不相同,大大削弱了許多傳統(tǒng)因素在選擇閥門時(shí)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(tǒng)因素仍然很重要,但它們只關(guān)注良工閥門“靜態(tài)"性能。事實(shí)上,他們?cè)谶@里。“工作臺(tái)"閥門測(cè)量的結(jié)果很難說(shuō)明閥門在實(shí)際運(yùn)行條件下會(huì)表現(xiàn)出什么樣的性能。傳統(tǒng)理論認(rèn)為,仔細(xì)調(diào)整靜態(tài)因素會(huì)使閥門(從而使整個(gè)電路)獲得良好的性能。然而,現(xiàn)在我們意識(shí)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(jìn)行的成千上萬(wàn)次性能檢查證明,多達(dá)50%的閥門(其中許多是通過(guò)考慮傳統(tǒng)因素選擇的)對(duì)優(yōu)化控制電路的性能沒(méi)有太大影響。后續(xù)研究表明,閥門的動(dòng)態(tài)特性在降低工藝變性方面發(fā)揮著重要作用。在許多關(guān)鍵過(guò)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(chǎn)效率,減少?gòu)U物,從而達(dá)到100多萬(wàn)美元的經(jīng)濟(jì)效益。顯然,這種經(jīng)濟(jì)效益使我們能夠完全否認(rèn)傳統(tǒng)的做法,即只根據(jù)閥門的初始購(gòu)買價(jià)格來(lái)決定是否購(gòu)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(tǒng)觀點(diǎn)總是認(rèn)為,過(guò)程優(yōu)化的改進(jìn)總是來(lái)自于控制室控制儀器的升級(jí)。然而,測(cè)試數(shù)據(jù)表明,在使用相同控制儀器的情況下,閥門的動(dòng)態(tài)特性對(duì)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.
