膨脹罐介紹：

膨脹(zhang)罐(guan)用(yong)(yong)(yong)于系統中(zhong)起緩沖(chong)壓力波(bo)動及部分(fen)給水(shui)的作用(yong)(yong)(yong)，在熱力系統中(zhong)主(zhu)要是用(yong)(yong)(yong)來吸收工作介質因溫度變(bian)化增加的那部分(fen)體積；在供水(shui)系統中(zhong)主(zhu)要用(yong)(yong)(yong)來吸收系統因閥門(men)、水(shui)泵(beng)等開(kai)和關(guan)所引(yin)起的水(shui)錘(chui)沖(chong)擊，以及夜(ye)間少量補水(shui)使供水(shui)系統主(zhu)泵(beng)休眠從(cong)而減少用(yong)(yong)(yong)電，延長水(shui)泵(beng)使用(yong)(yong)(yong)壽命。

　　膨脹罐(guan)—由(you)罐(guan)體、氣(qi)(qi)囊、進/出水口(kou)(kou)及(ji)補氣(qi)(qi)口(kou)(kou)四部份組成。罐(guan)體一般(ban)為(wei)碳鋼材質，外面是防銹烤漆層；氣(qi)(qi)囊為(wei)EPDM環保橡膠；氣(qi)(qi)囊與罐(guan)體之間(jian)的預充氣(qi)(qi)體出廠(chang)時已充好，無(wu)須自己加氣(qi)(qi)。

　　膨(peng)(peng)脹(zhang)罐(guan)(guan)工作(zuo)原理：當外(wai)界(jie)有壓(ya)(ya)(ya)力(li)的(de)水(shui)(shui)(shui)進入膨(peng)(peng)脹(zhang)罐(guan)(guan)氣(qi)(qi)囊內時(shi)(shi)，密封在(zai)罐(guan)(guan)內的(de)氮氣(qi)(qi)被壓(ya)(ya)(ya)縮，根據波義耳氣(qi)(qi)體定律，氣(qi)(qi)體受到(dao)(dao)壓(ya)(ya)(ya)縮后體積變小壓(ya)(ya)(ya)力(li)升(sheng)高，直(zhi)到(dao)(dao)膨(peng)(peng)脹(zhang)罐(guan)(guan)內氣(qi)(qi)體壓(ya)(ya)(ya)力(li)與水(shui)(shui)(shui)的(de)壓(ya)(ya)(ya)力(li)達到(dao)(dao)一(yi)致時(shi)(shi)停止(zhi)進水(shui)(shui)(shui)。當水(shui)(shui)(shui)流失壓(ya)(ya)(ya)力(li)減低時(shi)(shi)膨(peng)(peng)脹(zhang)罐(guan)(guan)內氣(qi)(qi)體壓(ya)(ya)(ya)力(li)大于水(shui)(shui)(shui)的(de)壓(ya)(ya)(ya)力(li)，此時(shi)(shi)氣(qi)(qi)體膨(peng)(peng)脹(zhang)將(jiang)氣(qi)(qi)囊內的(de)水(shui)(shui)(shui)擠出補到(dao)(dao)系統，直(zhi)到(dao)(dao)氣(qi)(qi)體壓(ya)(ya)(ya)力(li)與水(shui)(shui)(shui)的(de)壓(ya)(ya)(ya)力(li)再次達到(dao)(dao)一(yi)致時(shi)(shi)停止(zhi)排水(shui)(shui)(shui)。

在產(chan)品的制作(zuo)與加工(gong)過程中，用戶可隨時致(zhi)電(dian)我廠生產(chan)科(ke)詢問產(chan)品的加工(gong)進度與制作(zuo)情況，亦可派人員來我廠親自(zi)監督產(chan)品制作(zuo)的每一進程。
