鍋爐操作的注意事項(xiàng)：1、鍋爐安全閥：安全閥室鍋爐的較重要安全裝置之一，能起到在超壓時(shí)及時(shí)泄放降壓的作用。安全閥應(yīng)該定期進(jìn)行整定才能投入使用，使用過(guò)程中要定期手動(dòng)排放或定期進(jìn)行功能試驗(yàn)，以保證不出現(xiàn)銹死卡住等導(dǎo)致安全閥失靈的問(wèn)題出現(xiàn)。2、鍋爐水位表：蒸汽鍋爐的水位表是直觀表現(xiàn)鍋爐內(nèi)水位位置的裝置，高于或低于水位表正常水位都是嚴(yán)重的操作錯(cuò)誤，極容易導(dǎo)致事故的發(fā)生，因此要定期進(jìn)行水位表沖洗并在使用過(guò)程中密切觀察水位位置。3、鍋爐壓力表：壓力表直觀反映鍋爐運(yùn)行壓力值，指示操作人員決不能超壓運(yùn)行。因此壓力表要求每半年校驗(yàn)一次，確保靈敏可靠。4、鍋爐排污裝置：排污裝置是排出鍋爐內(nèi)水垢雜質(zhì)的設(shè)備，能有效控制鍋爐不結(jié)垢不堆渣，同時(shí)經(jīng)常觸摸排污閥的后部管道還可以檢查是否存在泄漏問(wèn)題。5、鍋爐的定壓膨脹裝置：熱水鍋爐的定壓膨脹裝置是防止鍋爐汽化超壓的有效設(shè)備，也是保證熱水系統(tǒng)順暢流通不積氣的有效設(shè)備，用戶要確保其好用。6、常壓鍋爐：常壓鍋爐如果安裝正確不會(huì)出現(xiàn)超壓?jiǎn)栴}，但常壓鍋爐冬季一定要注意防凍，如果管路凍死必須人工解凍方可使用，否則就會(huì)發(fā)生管路堵死超壓，這一點(diǎn)至關(guān)重要。

多溫區(qū)管式爐注意事項(xiàng)：1.多溫區(qū)管式爐操作注意事項(xiàng)爐子初次使用或長(zhǎng)時(shí)間不用后，要在120度左右烘爐1小時(shí)，在300度左右烘烤2小時(shí)后使用，以免造成爐膛開(kāi)裂。爐溫不得超過(guò)額定溫度，以免損壞加熱元件及爐襯。2.禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保護(hù)顱內(nèi)清潔。3.爐體若采用硅鉬棒做加熱元件，依據(jù)硅鉬棒的物理特性，常溫下脆性很大，因此在加熱元件安裝好后不能隨意拆裝和搬動(dòng)爐體，4.冷爐使用時(shí)，由于爐膛是冷的，須大量吸熱，所以低溫段升溫速率不宜過(guò)快，各種溫度段的升溫速率差別不宜太大，設(shè)置升溫速率時(shí)應(yīng)充分考慮所燒結(jié)材料的物理化學(xué)性質(zhì)，以免出現(xiàn)噴料現(xiàn)象，污染爐膛，5.定期檢查溫度控制系統(tǒng)的電器連接部分的接觸是良好，應(yīng)特別注意加熱元件的各連接是否緊固。6.硅鉬棒作為加熱元件時(shí)不宜在400-700度溫度段長(zhǎng)時(shí)間運(yùn)行，否則硅鉬棒將發(fā)生低溫氧化。7.硅鉬棒做加熱元件時(shí)，長(zhǎng)時(shí)間運(yùn)行，阻值會(huì)逐漸增大，這種現(xiàn)象叫“老化”。管式爐具有抗干擾能力強(qiáng)，控制精度高，沖溫值小。茂名管式爐生產(chǎn)廠家</p><p
