試驗(yàn)箱主要系統(tǒng)的工作原理和工作過(guò)程是怎樣
- 試驗(yàn)箱主要系統(tǒng)的工作原理和工作過(guò)程是怎樣深入了解試驗(yàn)箱的工作原理和工作過(guò)程,才能迅速的解決試驗(yàn)箱在運(yùn)行過(guò)程中出現(xiàn)的問(wèn)題。希望本文能夠?qū)氖颅h(huán)境設(shè)備管理運(yùn)行維護(hù)人員有所裨益。共同推動(dòng)我國(guó)環(huán)境工程的發(fā)展。恒溫恒濕箱的原理:綜合試驗(yàn)箱由制冷系統(tǒng),加熱系統(tǒng),控制系統(tǒng),溫度系統(tǒng)空氣循環(huán)系統(tǒng),和傳感器系統(tǒng)等組成,上述系統(tǒng)分屬電氣和機(jī)械制冷兩大方面。下面初步敘述幾個(gè)主要系統(tǒng)的工作原理和工作過(guò)程。制冷系統(tǒng):制冷系統(tǒng)是綜合試驗(yàn)箱的關(guān)鍵部分之一。一般來(lái)說(shuō),試驗(yàn)箱的制冷方式都是機(jī)械制冷以及輔助液氮制冷,機(jī)械制冷采用蒸汽壓縮式制冷,它們主要由壓縮機(jī),冷凝器,節(jié)流機(jī)構(gòu)和蒸發(fā)器組成,由于我們?cè)囼?yàn)的溫度低溫要達(dá)到-55℃,單級(jí)制冷難以滿(mǎn)足滿(mǎn)足要求,因此綜合試驗(yàn)箱的制冷方式一般采用復(fù)疊式制冷。加熱系統(tǒng):試驗(yàn)箱的加熱系統(tǒng)相對(duì)制冷系統(tǒng)而言,是比較簡(jiǎn)單。它主要有大功率電阻絲組成,由于試驗(yàn)箱要求的升溫速率較大,因此試驗(yàn)箱的加熱系統(tǒng)功率都比較大,而且在試驗(yàn)箱的底板也設(shè)有加熱器。傳感器系統(tǒng):試驗(yàn)箱的傳感器主要是溫度和濕度傳感器。溫度傳感器應(yīng)用較多的是鉑電組和熱電偶。濕度的測(cè)量方法有兩種:干濕球溫度計(jì)法和固態(tài)電子式傳感器直接測(cè)量法。由于干濕球法測(cè)量精度不高,現(xiàn)在的試驗(yàn)箱正逐步的以固態(tài)傳感器代替干濕球來(lái)進(jìn)行濕度的測(cè)量。試驗(yàn)箱的加濕方式一般采用蒸汽加濕法,即將低壓蒸汽直接注入試驗(yàn)空間加濕。這種加濕方法加濕能力,速度快,加濕控制靈敏,尤其在降溫時(shí)容易實(shí)現(xiàn)強(qiáng)制加濕。試驗(yàn)箱的除濕方式有兩種:機(jī)械制冷除濕和干燥除濕。機(jī)械制冷除濕的除濕原理是將空氣冷卻到露點(diǎn)溫度以下,使大于飽和含濕量的水汽凝結(jié)析出,這樣就降低了濕度。干燥器除濕是利用氣泵將試驗(yàn)箱內(nèi)的空氣抽出,并將干燥的空氣注入,同時(shí)將濕空氣送入可循環(huán)利用的干燥進(jìn)行干燥,干燥完后又送入試驗(yàn)箱內(nèi),紫外加速試驗(yàn)箱如此反復(fù)循環(huán)進(jìn)行除濕?,F(xiàn)在大部分綜合試驗(yàn)箱采用前一種除濕方式法,后一種的除濕方法,可以使露點(diǎn)溫度達(dá)到0℃一下。適用于有特殊要求的場(chǎng)合,但費(fèi)用較貴。上海凱朗儀器設(shè)備廠專(zhuān)業(yè)生產(chǎn)鼓風(fēng)干燥箱、真空干燥箱、馬弗爐、生化培養(yǎng)箱、二氧化碳培養(yǎng)箱、電熱恒溫培養(yǎng)箱、試驗(yàn)箱、恒溫?fù)u床、水槽、水浴鍋等實(shí)驗(yàn)室設(shè)備。咨詢(xún)電話:021-57180039[詳細(xì)]

凱朗試驗(yàn)箱主要系統(tǒng)的工作原理和工作過(guò)程是怎樣
- 凱朗試驗(yàn)箱主要系統(tǒng)的工作原理和工作過(guò)程是怎樣深入了解試驗(yàn)箱的工作原理和工作過(guò)程,才能迅速的解決試驗(yàn)箱在運(yùn)行過(guò)程中出現(xiàn)的問(wèn)題。希望本文能夠?qū)氖颅h(huán)境設(shè)備管理運(yùn)行維護(hù)人員有所裨益。共同推動(dòng)我國(guó)環(huán)境工程的發(fā)展。恒溫恒濕箱的原理:綜合試驗(yàn)箱由制冷系統(tǒng),加熱系統(tǒng),控制系統(tǒng),溫度系統(tǒng)空氣循環(huán)系統(tǒng),和傳感器系統(tǒng)等組成,上述系統(tǒng)分屬電氣和機(jī)械制冷兩大方面。下面初步敘述幾個(gè)主要系統(tǒng)的工作原理和工作過(guò)程。制冷系統(tǒng):制冷系統(tǒng)是綜合試驗(yàn)箱的關(guān)鍵部分之一。一般來(lái)說(shuō),試驗(yàn)箱的制冷方式都是機(jī)械制冷以及輔助液氮制冷,機(jī)械制冷采用蒸汽壓縮式制冷,它們主要由壓縮機(jī),冷凝器,節(jié)流機(jī)構(gòu)和蒸發(fā)器組成,由于我們?cè)囼?yàn)的溫度低溫要達(dá)到-55℃,單級(jí)制冷難以滿(mǎn)足滿(mǎn)足要求,因此綜合試驗(yàn)箱的制冷方式一般采用復(fù)疊式制冷。加熱系統(tǒng):試驗(yàn)箱的加熱系統(tǒng)相對(duì)制冷系統(tǒng)而言,是比較簡(jiǎn)單。它主要有大功率電阻絲組成,由于試驗(yàn)箱要求的升溫速率較大,因此試驗(yàn)箱的加熱系統(tǒng)功率都比較大,而且在試驗(yàn)箱的底板也設(shè)有加熱器。傳感器系統(tǒng):試驗(yàn)箱的傳感器主要是溫度和濕度傳感器。溫度傳感器應(yīng)用較多的是鉑電組和熱電偶。濕度的測(cè)量方法有兩種:干濕球溫度計(jì)法和固態(tài)電子式傳感器直接測(cè)量法。由于干濕球法測(cè)量精度不高,現(xiàn)在的試驗(yàn)箱正逐步的以固態(tài)傳感器代替干濕球來(lái)進(jìn)行濕度的測(cè)量。試驗(yàn)箱的加濕方式一般采用蒸汽加濕法,即將低壓蒸汽直接注入試驗(yàn)空間加濕。這種加濕方法加濕能力,速度快,加濕控制靈敏,尤其在降溫時(shí)容易實(shí)現(xiàn)強(qiáng)制加濕。試驗(yàn)箱的除濕方式有兩種:機(jī)械制冷除濕和干燥除濕。機(jī)械制冷除濕的除濕原理是將空氣冷卻到露點(diǎn)溫度以下,使大于飽和含濕量的水汽凝結(jié)析出,這樣就降低了濕度。干燥器除濕是利用氣泵將試驗(yàn)箱內(nèi)的空氣抽出,并將干燥的空氣注入,同時(shí)將濕空氣送入可循環(huán)利用的干燥進(jìn)行干燥,干燥完后又送入試驗(yàn)箱內(nèi),紫外加速試驗(yàn)箱如此反復(fù)循環(huán)進(jìn)行除濕?,F(xiàn)在大部分綜合試驗(yàn)箱采用前一種除濕方式法,后一種的除濕方法,可以使露點(diǎn)溫度達(dá)到0℃一下。適用于有特殊要求的場(chǎng)合,但費(fèi)用較貴。上海凱朗儀器設(shè)備廠專(zhuān)業(yè)生產(chǎn)鼓風(fēng)干燥箱、真空干燥箱、馬弗爐、生化培養(yǎng)箱、二氧化碳培養(yǎng)箱、電熱恒溫培養(yǎng)箱、試驗(yàn)箱、恒溫?fù)u床、水槽、水浴鍋等實(shí)驗(yàn)室設(shè)備。[詳細(xì)]
