我國(guó)對(duì)流散熱器目前主要有哪幾種?答:我國(guó)對(duì)流散熱器主要種類:鑄鐵散熱器:柱型、翼型鋼制散熱器:板型、柱型、管柱型、串片型、翅片管型、衛(wèi)浴型、鋼鋁復(fù)合柱翼型銅管類散熱器:銅鋁復(fù)合柱翼型、銅管鋁片對(duì)流型、衛(wèi)浴型鋁制散熱器:鋁制柱翼型、鑄鋁柱型不銹鋼散熱器:不銹鋼柱翼型、衛(wèi)浴型造成對(duì)流散熱器腐蝕的主要因素有哪些?答:不同金屬材質(zhì)散熱器腐蝕的因素有差異,綜合說(shuō)來(lái)主要因素如下:原材料本身抗腐蝕能力低,以及加工過(guò)程中的損傷和減薄供暖水質(zhì)不當(dāng)運(yùn)行維護(hù)不當(dāng)對(duì)流散熱器上必須裝放氣閥嗎?答:有的系統(tǒng)由于散熱器及水平支管均有.1的坡度,空氣可以自然排出,這時(shí)散熱器上的放氣閥并非必要。
一般排管制作加吊裝比安裝冷風(fēng)機(jī)的施工周期要高3~4倍,因此用在排管制作安裝上的人工費(fèi)就要比用在冷風(fēng)機(jī)安裝上的人工費(fèi)高出很多。發(fā)達(dá)的低溫冷庫(kù)內(nèi)都選用冷風(fēng)機(jī)降溫,很大一方面也是考慮到這方面因素。融霜方式:目前冷庫(kù)冷風(fēng)機(jī)常見(jiàn)的融霜方式有:自然化霜、水沖霜、電化霜和熱氟融霜。冷風(fēng)機(jī)自動(dòng)融霜比較容易實(shí)現(xiàn),化霜的水隨著冷風(fēng)機(jī)的化霜落水管流到冷庫(kù)外。鋁合金排管應(yīng)用較多的是熱氟融霜,但是排管在庫(kù)房分布廣化霜時(shí)的水滴會(huì)往下落,因此化霜時(shí)一般要把貨物轉(zhuǎn)移或蓋上防水塑料布,不如冷風(fēng)機(jī)化霜那么靈活、方便。

目前公司業(yè)務(wù)遍布全國(guó)各省市,經(jīng)過(guò)多年的服務(wù),總結(jié)出專為系統(tǒng)用戶服務(wù)的成熟模式,實(shí)現(xiàn)服務(wù)的人性化、流程的簡(jiǎn)單化以及管理的規(guī)范化,有效幫助客戶延長(zhǎng)電氣設(shè)備的使用周期,降低運(yùn)營(yíng)成本,控制停產(chǎn)風(fēng)險(xiǎn)、提高生產(chǎn)效率!
不要帶電插拔各種控制板和插頭。因?yàn)樵诩与娗闆r下,插拔控制板會(huì)產(chǎn)生較強(qiáng)的感應(yīng)電動(dòng)勢(shì),這時(shí)瞬間反擊電壓很高,很容易損壞相應(yīng)的控制板和插頭。檢修時(shí)不要盲目亂敲亂碰,以免擴(kuò)大故障,越修越壞。側(cè)裝式磁翻板液位計(jì)拆卸、調(diào)整儀表時(shí),應(yīng)記錄原來(lái)的位置,以便復(fù)原。修理精密儀器儀表時(shí),如不慎將小零件彈飛可采取磁鐵掃描和視線掃描方法進(jìn)行尋找。造成磁翻板液位計(jì)出現(xiàn)假液位的原因有以下幾種:1.液位計(jì)內(nèi)部的波導(dǎo)絲故障,如松動(dòng)、密封不好進(jìn)水銹蝕等,造成信號(hào)失真;2.波導(dǎo)絲安裝不正確,信號(hào)傳遞失真;3.外界干擾信號(hào)過(guò)大,造成電路得到的是假的信號(hào),不是實(shí)際測(cè)量的信號(hào);4.信號(hào)處理電路故障。
