壓鑄模溫機的原理是(shi)將電加(jia)熱器直(zhi)接插入有機(ji)載體(ti)中直(zhi)接加(jia)熱,并通過高溫(wen)(wen)油泵進行液相循環(huan)(huan)槳加(jia)熱后地(di)導熱油輸(shu)送到(dao)加(jia)熱流道,再(zai)由用(yong)熱設(she)備出(chu)油口回到(dao)及其(qi),形(xing)成一個(ge)完整地(di)循環(huan)(huan)加(jia)熱系統。壓鑄模溫(wen)(wen)機(ji)采用(yong)數顯溫(wen)(wen)控儀控溫(wen)(wen)方式(shi),它具有超(chao)溫(wen)(wen)報(bao)警、低油位(wei)缺油報(bao)警、超(chao)壓力報(bao)警功能等保護。
壓(ya)鑄模溫機的(de)(de)循環管道(dao)(dao)(dao)試(shi)壓(ya)結束后,對管道(dao)(dao)(dao)系(xi)統(tong)(tong)進行吹洗。吹洗前應(ying)將管道(dao)(dao)(dao)系(xi)統(tong)(tong)地孔(kong)板(ban)、濾網、止回閥(fa)等拆(chai)除,并(bing)采(cai)取措施防(fang)止管道(dao)(dao)(dao)里臟(zang)物體吹入用熱(re)設備。他采(cai)用壓(ya)縮空氣作為(wei)吹洗介質,壓(ya)力不(bu)得大于0.5Mpa,狀態流速(su)不(bu)低于20m/s。進行試(shi)壓(ya)吹洗后,系(xi)統(tong)(tong)立(li)即可(ke)以(yi)加(jia)油,首先蔣泵入口、系(xi)統(tong)(tong)出口及(ji)系(xi)統(tong)(tong)閥(fa)門(men)開啟,加(jia)熱(re)器(qi)上部(bu)與(yu)膨脹(zhang)槽之間的(de)(de)排(pai)氣閥(fa)門(men)保(bao)持打開形(xing)式,然后從膨脹(zhang)槽頂部(bu)加(jia)油,加(jia)油過程中隨時要注意系(xi)統(tong)(tong)排(pai)氣,以(yi)保(bao)證系(xi)統(tong)(tong)加(jia)滿油使膨脹(zhang)槽液位達三(san)分之一即可(ke)。
壓鑄模溫機中導熱油的冷(leng)卻裝置分為(wei)水冷(leng)式(shi)(shi)(shi)溫控(kong)單元組:雙倍采用殼管式(shi)(shi)(shi),內部(bu)管設(she)計(ji)為(wei)直(zhi)管式(shi)(shi)(shi)或(huo)型管式(shi)(shi)(shi),換熱效率采用氣控(kong)制(zhi)閥,閥門的反應(ying)速度(du)(du)超快,推薦同時采用PID溫度(du)(du)控(kong)制(zhi),溫度(du)(du)精度(du)(du)可達到±0.4℃。適合(he)合(he)用于溫度(du)(du)控(kong)制(zhi)精度(du)(du)高、升溫降(jiang)溫反應(ying)速度(du)(du)比較(jiao)(jiao)快且較(jiao)(jiao)頻繁的設(she)備上。壓鑄模溫機是化(hua)工、紡織、印染、食品、塑料、薄(bo)膜等行業中一種高效節能供熱設(she)備。
