高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)常用(yong)(yong)(yong)(yong)(yong)(yong)在在石油(you)化工廠，除(chu)了技(ji)術(shu)(shu)用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)(如熱(re)油(you)泵(beng)(beng)(beng)、油(you)漿(jiang)泵(beng)(beng)(beng)等(deng)(deng))、鍋爐(lu)用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)(如鍋爐(lu)給水泵(beng)(beng)(beng)，熱(re)水循(xun)環泵(beng)(beng)(beng)等(deng)(deng))以外，還有熱(re)載體(ti)(ti)用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)。技(ji)術(shu)(shu)用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)所輸送的液體(ti)(ti)的性質和(he)溫(wen)(wen)(wen)(wen)(wen)度隨技(ji)術(shu)(shu)進程的不一(yi)樣而不一(yi)樣，而熱(re)載體(ti)(ti)用(yong)(yong)(yong)(yong)(yong)(yong)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)泵(beng)(beng)(beng)，在高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)下熱(re)載體(ti)(ti)的性質比較穩定，蒸汽壓也較低，簡單(dan)精確地操(cao)控(kong)溫(wen)(wen)(wen)(wen)(wen)度將熱(re)量傳送給其他液體(ti)(ti)(傳熱(re)用(yong)(yong)(yong)(yong)(yong)(yong)前言用(yong)(yong)(yong)(yong)(yong)(yong))。作(zuo)為熱(re)載體(ti)(ti)的液體(ti)(ti)有：重(zhong)柴油(you)(芳烴抽提用(yong)(yong)(yong)(yong)(yong)(yong))、有機溶劑(如異熱(re)姆(mu)等(deng)(deng))和(he)熔鹽(鈉鹽和(he)鉀鹽的混合物(wu))。
高(gao)溫泵的結構特色如下:
1)泵(beng)的熱脹(zhang)大(da)(da)：因(yin)(yin)為泵(beng)體(ti)和(he)轉子選用不一樣材料(liao)制成，因(yin)(yin)為脹(zhang)大(da)(da)系數和(he)溫度的不一樣，它(ta)們之間的空(kong)隙(xi)在(zai)(zai)熱態(tai)下(xia)(xia)會變小(xiao)，因(yin)(yin)而，首先(xian)應思考(kao)在(zai)(zai)冷態(tai)下(xia)(xia)的空(kong)隙(xi)比-般泵(beng)大(da)(da)一些。此外(wai)，軸套和(he)軸(徑(jing)向和(he)軸向)的空(kong)隙(xi)合作(zuo)要恰當，并(bing)且要思考(kao)熱態(tai)下(xia)(xia)的對基地。
2)泵(beng)的(de)支(zhi)承：因為(wei)不可防止的(de)熱脹(zhang)大會使泵(beng)體曲解變(bian)形(xing)。通常(chang)選(xuan)用基地(di)支(zhi)持的(de)結構，以(yi)確(que)保泵(beng)體自由地(di)均勻(yun)脹(zhang)大，防止發(fa)作泵(beng)體變(bian)形(xing)形(xing)成軸(zhou)曲折而抱軸(zhou)。
3)泵體的耐壓強度：通常高溫泵均處于較高的壓力下(xia)作業，因而(er)，必(bi)須(xu)思考泵在高溫下(xia)的耐壓強度。此外(wai)還必(bi)須(xu)思考因為配管熱脹大而(er)施加在泵體的負荷效果。
4)泵體和軸封(feng)(feng)的(de)(de)密(mi)封(feng)(feng)：泵體選(xuan)用適用于(yu)高溫下(xia)密(mi)封(feng)(feng)的(de)(de)墊片(pian)(如環(huan)繞(rao)式(shi)墊片(pian))和軸封(feng)(feng)選(xuan)用高溫下(xia)作(zuo)業牢靠的(de)(de)機械密(mi)封(feng)(feng)與浮(fu)環(huan)密(mi)封(feng)(feng)并相應(ying)地采(cai)納冷(leng)卻和沖刷(shua)等辦法(fa)。
5)機座和軸(zhou)封等相應(ying)地采納冷卻辦法。
此外，在運(yun)用方(fang)面應采納恰當的預熱(re)和升溫(wen)(wen)辦(ban)法。為了不方(fang)便泵體(ti)內外溫(wen)(wen)差(cha)過大，可選用保(bao)溫(wen)(wen)辦(ban)法。
