膨脹罐介紹：

膨脹罐用(yong)(yong)(yong)(yong)于系(xi)統(tong)(tong)中起緩沖(chong)壓(ya)力波動及部分給水(shui)(shui)的作(zuo)用(yong)(yong)(yong)(yong)，在熱(re)力系(xi)統(tong)(tong)中主要是用(yong)(yong)(yong)(yong)來吸收工作(zuo)介質因溫度變化增加的那部分體(ti)積；在供(gong)(gong)水(shui)(shui)系(xi)統(tong)(tong)中主要用(yong)(yong)(yong)(yong)來吸收系(xi)統(tong)(tong)因閥(fa)門(men)、水(shui)(shui)泵(beng)等開和關所引起的水(shui)(shui)錘(chui)沖(chong)擊，以(yi)及夜間少量補(bu)水(shui)(shui)使供(gong)(gong)水(shui)(shui)系(xi)統(tong)(tong)主泵(beng)休(xiu)眠從而減少用(yong)(yong)(yong)(yong)電，延長水(shui)(shui)泵(beng)使用(yong)(yong)(yong)(yong)壽命(ming)。

　　膨脹罐—由罐體、氣(qi)(qi)囊、進/出(chu)水口及補氣(qi)(qi)口四部份組成。罐體一般為碳鋼材質(zhi)，外面(mian)是防(fang)銹烤漆層；氣(qi)(qi)囊為EPDM環保橡膠；氣(qi)(qi)囊與(yu)罐體之間(jian)的預充(chong)氣(qi)(qi)體出(chu)廠(chang)時已充(chong)好，無須自己加氣(qi)(qi)。

　　膨脹(zhang)罐工作(zuo)原(yuan)理：當外(wai)界有壓(ya)力(li)(li)的(de)水(shui)(shui)(shui)進入膨脹(zhang)罐氣(qi)(qi)囊內(nei)時(shi)，密封在罐內(nei)的(de)氮氣(qi)(qi)被壓(ya)縮，根據波義耳氣(qi)(qi)體(ti)定(ding)律，氣(qi)(qi)體(ti)受(shou)到(dao)壓(ya)縮后體(ti)積變小壓(ya)力(li)(li)升高，直到(dao)膨脹(zhang)罐內(nei)氣(qi)(qi)體(ti)壓(ya)力(li)(li)與(yu)水(shui)(shui)(shui)的(de)壓(ya)力(li)(li)達到(dao)一致時(shi)停止(zhi)進水(shui)(shui)(shui)。當水(shui)(shui)(shui)流失壓(ya)力(li)(li)減(jian)低時(shi)膨脹(zhang)罐內(nei)氣(qi)(qi)體(ti)壓(ya)力(li)(li)大于水(shui)(shui)(shui)的(de)壓(ya)力(li)(li)，此時(shi)氣(qi)(qi)體(ti)膨脹(zhang)將氣(qi)(qi)囊內(nei)的(de)水(shui)(shui)(shui)擠出補到(dao)系統，直到(dao)氣(qi)(qi)體(ti)壓(ya)力(li)(li)與(yu)水(shui)(shui)(shui)的(de)壓(ya)力(li)(li)再次達到(dao)一致時(shi)停止(zhi)排水(shui)(shui)(shui)。

在產(chan)(chan)品的制(zhi)(zhi)作與(yu)加(jia)工(gong)過(guo)程中(zhong)，用戶(hu)可(ke)隨時致電(dian)我廠(chang)生產(chan)(chan)科(ke)詢問產(chan)(chan)品的加(jia)工(gong)進度與(yu)制(zhi)(zhi)作情況，亦可(ke)派人(ren)員來我廠(chang)親自監督產(chan)(chan)品制(zhi)(zhi)作的每一進程。
