壓(ya)縮(suo)(suo)空氣(qi)通常被(bei)視為一種支(zhi)持功能(neng)(neng)，廣泛用(yong)于生產設施中(zhong)(zhong)的(de)過程機(ji)械操作(zuo)以及(ji)氣(qi)動閥、氣(qi)缸和控(kong)制(zhi)器驅(qu)動與(yu)控(kong)制(zhi)。但(dan)是，壓(ya)縮(suo)(suo)空氣(qi)的(de)質量(liang)和有效性可(ke)能(neng)(neng)會(hui)對工廠的(de)核心生產產生重大影響(xiang)。壓(ya)縮(suo)(suo)空氣(qi)和氣(qi)體系(xi)統(tong)制(zhi)造商CompAir使(shi)用(yong)維薩拉DRYCAP?手持式露點(dian)儀DM70在其AirWorx?服務(wu)中(zhong)(zhong)包括(kuo)的(de)AirAudit過程中(zhong)(zhong)測量(liang)壓(ya)力露點(dian)。在這(zhe)項審核的(de)過程中(zhong)(zhong)，工作(zuo)人員會(hui)測量(liang)與(yu)壓(ya)縮(suo)(suo)空氣(qi)系(xi)統(tong)性能(neng)(neng)相關的(de)許多參數，以便提高其能(neng)(neng)源效率。

　　COMPAIR是全球壓(ya)(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)(qi)(qi)和(he)(he)氣(qi)(qi)(qi)體(ti)(ti)系統制造商之一，在(zai)英(ying)國(guo)、德國(guo)、美(mei)國(guo)、加拿大(da)和(he)(he)中國(guo)均有生產設(she)施。CompAir的(de)(de)(de)壓(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)、設(she)備和(he)(he)服(fu)務廣泛用(yong)于(yu)全球，為眾多(duo)應用(yong)提供高(gao)質量、經濟、清潔和(he)(he)可靠的(de)(de)(de)壓(ya)(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)(qi)(qi)和(he)(he)氣(qi)(qi)(qi)體(ti)(ti)。公司的(de)(de)(de)產品范圍包(bao)括旋轉螺桿(gan)式、無油(you)式、葉(xie)片(pian)式、活塞式和(he)(he)便攜式壓(ya)(ya)(ya)(ya)縮(suo)(suo)機(ji)，以及(ji)面向一般工(gong)業(ye)、海上、無油(you)、建筑和(he)(he)高(gao)壓(ya)(ya)(ya)(ya)船用(yong)氣(qi)(qi)(qi)體(ti)(ti)壓(ya)(ya)(ya)(ya)縮(suo)(suo)用(yong)戶的(de)(de)(de)輔助(zhu)產品和(he)(he)服(fu)務。他們的(de)(de)(de)AIRWORX部門成立于(yu)2001年，專(zhuan)職進行壓(ya)(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)(qi)(qi)系統評估和(he)(he)節(jie)能(neng)改(gai)進建議(yi)，包(bao)括外包(bao)完整壓(ya)(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)(qi)(qi)需求(qiu)的(de)(de)(de)可能(neng)性。CompAir的(de)(de)(de)AirWorx?服(fu)務有助(zhu)于(yu)節(jie)省工(gong)廠的(de)(de)(de)成本(ben)(ben)和(he)(he)資(zi)(zi)(zi)本(ben)(ben)投(tou)資(zi)(zi)(zi)，并(bing)有助(zhu)于(yu)實現(xian)節(jie)能(neng)目(mu)標。通過AirWorx?服(fu)務，客戶無需資(zi)(zi)(zi)本(ben)(ben)投(tou)資(zi)(zi)(zi)即可從CompAir購買所需的(de)(de)(de)壓(ya)(ya)(ya)(ya)縮(suo)(suo)空(kong)氣(qi)(qi)(qi)。

壓(ya)縮空氣僅(jin)被視為支持功能：

　　由于被(bei)視為支持活動，壓(ya)(ya)縮(suo)空氣(qi)很少得到應得的關注。目前，整個行(xing)業8-10%的電(dian)能消耗用(yong)于壓(ya)(ya)縮(suo)空氣(qi)，而(er)產生的壓(ya)(ya)縮(suo)空氣(qi)中大約有30%被(bei)白白浪費掉了。雖然節能潛力巨(ju)大，但壓(ya)(ya)縮(suo)空氣(qi)系統(tong)的運營節省難以實現，因為改進通常不符(fu)合公司項目的標準。

　　從用(yong)(yong)戶的(de)(de)角(jiao)度(du)來(lai)看(kan)，壓(ya)縮(suo)(suo)(suo)(suo)空氣(qi)(qi)只是可與(yu)電、水或氣(qi)(qi)相提并論的(de)(de)另一(yi)種公共設(she)施(shi)。但壓(ya)縮(suo)(suo)(suo)(suo)空氣(qi)(qi)主要(yao)(yao)是在場外生(sheng)成并根據需要(yao)(yao)提供給用(yong)(yong)戶。壓(ya)縮(suo)(suo)(suo)(suo)空氣(qi)(qi)的(de)(de)性質不(bu)允許遠距離(li)運輸，因此大(da)多數用(yong)(yong)戶一(yi)直以來(lai)都(dou)擁有并運行(xing)自己的(de)(de)壓(ya)縮(suo)(suo)(suo)(suo)空氣(qi)(qi)系(xi)(xi)統(tong)。這(zhe)些(xie)系(xi)(xi)統(tong)通常(chang)是在數十年之前開發的(de)(de)，目(mu)前的(de)(de)應用(yong)(yong)通常(chang)與(yu)設(she)計(ji)系(xi)(xi)統(tong)時(shi)的(de)(de)情況顯著不(bu)同。此外，由于維(wei)護預(yu)算(suan)的(de)(de)限制(zhi)，這(zhe)些(xie)系(xi)(xi)統(tong)經常(chang)被忽(hu)視，導致系(xi)(xi)統(tong)性能不(bu)佳，用(yong)(yong)戶無法(fa)理解壓(ya)縮(suo)(suo)(suo)(suo)空氣(qi)(qi)供應效(xiao)率低(di)下所導致的(de)(de)增量成本。

　　在歐盟(meng)的(de)(de)一項名為“歐盟(meng)的(de)(de)壓縮空氣系統——能(neng)(neng)耗、排放、節能(neng)(neng)潛力(li)和政(zheng)策(ce)措施(shi)”的(de)(de)研究中，作者在引言中指出，“實(shi)(shi)現5%到50%的(de)(de)節能(neng)(neng)是(shi)(shi)有可能(neng)(neng)的(de)(de)。然而在當前的(de)(de)市場和決策(ce)機(ji)制(zhi)下，沒(mei)有實(shi)(shi)現大規模(mo)節能(neng)(neng)的(de)(de)技術和經濟潛力(li)。”CompAir的(de)(de)想法(fa)是(shi)(shi)將資本(ben)成本(ben)從這個等式中剔(ti)除，通過簽訂AirWorx供應協(xie)議來外包壓縮空氣的(de)(de)生產(chan)，從而簡單地實(shi)(shi)現運(yun)營(ying)節省。AirWorx方(fang)(fang)法(fa)是(shi)(shi)一種(zhong)合作協(xie)議，須使雙(shuang)方(fang)(fang)都受益才能(neng)(neng)成功(gong)。這種(zhong)益處來自于(yu)系統性能(neng)(neng)的(de)(de)改進以(yi)及讓(rang)雙(shuang)方(fang)(fang)都能(neng)(neng)專注于(yu)他們的(de)(de)核心(xin)業(ye)務。CompAir沒(mei)有使用單一型號(hao)或標準(zhun)服(fu)務包，而是(shi)(shi)采用模(mo)塊化方(fang)(fang)法(fa)并與客戶(hu)一起尋找解決方(fang)(fang)案(an)。

AirWorx?AirAudit：

　　為(wei)(wei)了(le)(le)讓雙方了(le)(le)解供應側和配銷網(wang)絡的(de)目前(qian)績效，對壓縮(suo)(suo)空(kong)氣(qi)系統進(jin)行(xing)了(le)(le)審核。這有助于確定工廠(chang)當前(qian)的(de)壓縮(suo)(suo)空(kong)氣(qi)成本，并(bing)成為(wei)(wei)衡量未來改(gai)進(jin)的(de)基準。此(ci)審核涵蓋(gai)現有系統中(zhong)的(de)所有相關(guan)參數：整個網(wang)絡中(zhong)的(de)功耗(hao)、流量、壓力、質量、濕度(du)和損耗(hao)，以(yi)及任何其他(ta)相關(guan)參數。準確的(de)結果至關(guan)重要，因為(wei)(wei)這些數據將用作任何壓縮(suo)(suo)空(kong)氣(qi)項目的(de)基礎(chu)。

苛刻條件下的露點測量：

　　為了在(zai)AirAudit過程中測量壓力(li)露(lu)點(dian)(dian)(dian)，CompAir使用(yong)了維(wei)(wei)薩拉手持(chi)式(shi)露(lu)點(dian)(dian)(dian)儀(yi)DM70。對(dui)于(yu)這項服務，需要一(yi)種既可(ke)以處理(li)露(lu)點(dian)(dian)(dian)低至-70°C的(de)干燥空(kong)氣，也(ye)(ye)可(ke)以處理(li)含有(you)(you)冷凝水的(de)系統的(de)儀(yi)器(qi)。通常(chang)，具有(you)(you)壓縮空(kong)氣干燥功能(neng)的(de)壓縮空(kong)氣系統的(de)預期露(lu)點(dian)(dian)(dian)在(zai)+5°C到-40°C之間，但(dan)由于(yu)干燥機并(bing)不總是正常(chang)工作，因此傳感(gan)器(qi)也(ye)(ye)需要能(neng)夠處理(li)潮濕(shi)(shi)條件。我們之前使用(yong)的(de)傳感(gan)器(qi)在(zai)變(bian)濕(shi)(shi)后需要重(zhong)新校準，但(dan)DM70在(zai)發生冷凝的(de)情況下(xia)仍能(neng)正常(chang)運行(xing)。對(dui)于(yu)在(zai)全球開展(zhan)運營的(de)CompAir而言，擁有(you)(you)一(yi)個(ge)同樣在(zai)全球開展(zhan)運營的(de)合作伙(huo)伴也(ye)(ye)很重(zhong)要，以便在(zai)需要時(shi)可(ke)以在(zai)當(dang)地找到支持(chi)。DM70性能(neng)可(ke)靠，而且提供便于(yu)用(yong)戶使用(yong)的(de)功能(neng)，例如多種語言選項。在(zai)這些方面，維(wei)(wei)薩拉完全滿足CompAir的(de)預期。
