膨脹罐介紹：

膨脹罐用(yong)(yong)(yong)(yong)于系(xi)統(tong)(tong)中(zhong)起緩沖壓力波動及部(bu)分給水(shui)的(de)作(zuo)用(yong)(yong)(yong)(yong)，在(zai)熱力系(xi)統(tong)(tong)中(zhong)主(zhu)要是用(yong)(yong)(yong)(yong)來吸(xi)收工作(zuo)介(jie)質因(yin)溫(wen)度變化增加的(de)那部(bu)分體積；在(zai)供水(shui)系(xi)統(tong)(tong)中(zhong)主(zhu)要用(yong)(yong)(yong)(yong)來吸(xi)收系(xi)統(tong)(tong)因(yin)閥門、水(shui)泵等開和關所引起的(de)水(shui)錘(chui)沖擊，以及夜(ye)間少量補水(shui)使供水(shui)系(xi)統(tong)(tong)主(zhu)泵休眠從而減(jian)少用(yong)(yong)(yong)(yong)電，延長水(shui)泵使用(yong)(yong)(yong)(yong)壽命。

　　膨脹(zhang)罐—由罐體(ti)、氣(qi)囊(nang)、進/出(chu)水(shui)口及(ji)補(bu)氣(qi)口四部(bu)份組成。罐體(ti)一般為(wei)碳鋼材質，外面是防(fang)銹烤(kao)漆(qi)層；氣(qi)囊(nang)為(wei)EPDM環(huan)保(bao)橡膠；氣(qi)囊(nang)與罐體(ti)之間的預(yu)充氣(qi)體(ti)出(chu)廠(chang)時已充好(hao)，無須自己加(jia)氣(qi)。

　　膨(peng)(peng)脹罐(guan)工作(zuo)原理(li)：當外界有(you)壓力(li)(li)的(de)(de)(de)水(shui)進(jin)入膨(peng)(peng)脹罐(guan)氣(qi)(qi)囊(nang)內(nei)時(shi)，密封在罐(guan)內(nei)的(de)(de)(de)氮氣(qi)(qi)被壓縮，根據波義耳(er)氣(qi)(qi)體定律，氣(qi)(qi)體受到(dao)(dao)壓縮后體積變(bian)小壓力(li)(li)升高，直(zhi)到(dao)(dao)膨(peng)(peng)脹罐(guan)內(nei)氣(qi)(qi)體壓力(li)(li)與水(shui)的(de)(de)(de)壓力(li)(li)達到(dao)(dao)一致時(shi)停止進(jin)水(shui)。當水(shui)流失壓力(li)(li)減低時(shi)膨(peng)(peng)脹罐(guan)內(nei)氣(qi)(qi)體壓力(li)(li)大于(yu)水(shui)的(de)(de)(de)壓力(li)(li)，此時(shi)氣(qi)(qi)體膨(peng)(peng)脹將氣(qi)(qi)囊(nang)內(nei)的(de)(de)(de)水(shui)擠出(chu)補到(dao)(dao)系統，直(zhi)到(dao)(dao)氣(qi)(qi)體壓力(li)(li)與水(shui)的(de)(de)(de)壓力(li)(li)再次(ci)達到(dao)(dao)一致時(shi)停止排水(shui)。

在產品的制(zhi)作(zuo)與加工過程(cheng)中，用戶可(ke)隨時致電我(wo)廠生產科詢問(wen)產品的加工進(jin)度與制(zhi)作(zuo)情(qing)況，亦(yi)可(ke)派人員來我(wo)廠親(qin)自監督產品制(zhi)作(zuo)的每一進(jin)程(cheng)。
