延長低溫循環(huán)泵使用壽命的保養(yǎng)秘訣

瀏覽次數(shù):34發(fā)布日期:2025-08-25
  低溫循環(huán)泵作為實(shí)驗(yàn)室與工業(yè)領(lǐng)域的控溫核心設(shè)備,其使用壽命與日常保養(yǎng)密切相關(guān)。掌握科學(xué)的保養(yǎng)方法,不僅能減少故障頻次,還能將設(shè)備使用壽命延長3-5年,核心秘訣圍繞“部件維護(hù)、介質(zhì)管理、環(huán)境控制”展開。?
 
  循環(huán)介質(zhì)維護(hù)是基礎(chǔ)且關(guān)鍵的一環(huán)。介質(zhì)需選用專用防凍液(如乙二醇水溶液、丙二醇溶液),嚴(yán)禁直接使用自來水(易結(jié)垢堵塞管路)。使用前需根據(jù)設(shè)備較低溫度要求配置合適濃度的防凍液(如-20℃需40%乙二醇溶液),每6個(gè)月檢測一次介質(zhì)濃度與純度:若濃度降低,及時(shí)補(bǔ)充對應(yīng)防凍液;若介質(zhì)出現(xiàn)渾濁、變色(如發(fā)黑、有沉淀物),需排空舊介質(zhì),用清水沖洗管路2-3次后,重新加注新介質(zhì),避免雜質(zhì)堵塞過濾器與蒸發(fā)器,導(dǎo)致制冷效率下降或壓縮機(jī)過載。?
 
  核心部件定期檢查與清潔不可忽視。每月需清理設(shè)備進(jìn)風(fēng)口、出風(fēng)口的防塵網(wǎng),用軟毛刷或壓縮空氣去除灰塵(灰塵堆積會導(dǎo)致散熱不良,壓縮機(jī)溫度過高);每3個(gè)月檢查循環(huán)泵葉輪:關(guān)閉設(shè)備電源,拆卸泵頭,若葉輪附著雜質(zhì),用軟布擦拭干凈,同時(shí)檢查葉輪是否有裂紋,若磨損嚴(yán)重及時(shí)更換,防止葉輪損壞導(dǎo)致循環(huán)流量下降;每半年檢查制冷系統(tǒng)管路:觀察管路是否有結(jié)霜、泄漏(如油漬痕跡),若出現(xiàn)局部結(jié)霜,可能是管路堵塞,需聯(lián)系專業(yè)人員清理;若發(fā)現(xiàn)泄漏,立即停用并檢修,避免制冷劑流失影響制冷效果。?
 
  規(guī)范操作與環(huán)境控制能減少設(shè)備損耗。設(shè)備啟動(dòng)前需確認(rèn)介質(zhì)液位在刻度線范圍內(nèi)(低于較低液位會導(dǎo)致循環(huán)泵空轉(zhuǎn),損壞密封件),嚴(yán)禁無介質(zhì)運(yùn)行;運(yùn)行時(shí)避免頻繁啟停(每次啟停間隔至少10分鐘),防止壓縮機(jī)因壓力驟變受損;設(shè)備需放置在通風(fēng)良好、溫度5-35℃的環(huán)境中,遠(yuǎn)離熱源(如烤箱、加熱器)與陽光直射,避免環(huán)境溫度過高增加壓縮機(jī)負(fù)荷;長期不用時(shí)(如超過1個(gè)月),需排空介質(zhì)(防止低溫下介質(zhì)結(jié)冰脹裂管路),擦拭設(shè)備表面后覆蓋防塵罩,每月通電運(yùn)行30分鐘,保持壓縮機(jī)潤滑。?
 
  安全系統(tǒng)維護(hù)需同步跟進(jìn)。定期測試設(shè)備的超溫保護(hù)、過電流保護(hù)功能:按說明書操作觸發(fā)保護(hù)機(jī)制,確認(rèn)設(shè)備能正常斷電報(bào)警;檢查電源線與插頭是否有破損、老化,若存在問題及時(shí)更換,避免漏電風(fēng)險(xiǎn)。?
 
  遵循這些保養(yǎng)秘訣,能有效降低低溫循環(huán)泵的故障概率,維持設(shè)備穩(wěn)定的控溫性能,讓設(shè)備長期處于高效運(yùn)行狀態(tài),為實(shí)驗(yàn)與生產(chǎn)提供可靠保障。?
