電磁門吸是什么
電磁門吸就是一種用于自動門的電磁鐵,是采用電磁原理產生吸力的門體定位裝置,又稱為電子門吸。由于其機械結構簡單、電磁原理可靠、低壓微電流工作,因而其使用壽命可達幾十年甚至上百年,與采用永磁鐵的普通門吸手控特點不同,它需要提供直流DC24V才能工作,可以現場手控和遠程電控,所以被廣泛應用于建筑智能門控設施中,目前電磁門吸主(zhu)要用于建筑物(wu)中(zhong)的防火(huo)門,并且必須(xu)通過國家消(xiao)防核心檢(jian)測合(he)格。
電磁門吸的工作原理
電(dian)磁(ci)門(men)(men)(men)(men)(men)吸(xi)(xi)主(zhu)要有(you)磁(ci)鐵主(zhu)體(安(an)裝(zhuang)在墻上)、吸(xi)(xi)板(安(an)裝(zhuang)在門(men)(men)(men)(men)(men)扇(shan)上)、安(an)裝(zhuang)底座或支架三部分組成(cheng)(cheng),帶有(you)釋放(fang)按鈕和緩沖(chong)墊。電(dian)磁(ci)門(men)(men)(men)(men)(men)吸(xi)(xi)的(de)(de)(de)(de)(de)工作原(yuan)理是由(you)電(dian)流轉化產(chan)生電(dian)磁(ci)力,吸(xi)(xi)附(fu)住安(an)裝(zhuang)固定在防(fang)(fang)火門(men)(men)(men)(men)(men)背后的(de)(de)(de)(de)(de)吸(xi)(xi)板,牢牢地吸(xi)(xi)住大(da)門(men)(men)(men)(men)(men),使(shi)大(da)門(men)(men)(men)(men)(men)不能關閉(bi),保(bao)證消(xiao)防(fang)(fang)通(tong)(tong)道(dao)暢(chang)通(tong)(tong)。比如,電(dian)磁(ci)門(men)(men)(men)(men)(men)吸(xi)(xi)與防(fang)(fang)火門(men)(men)(men)(men)(men)控制(zhi)器組成(cheng)(cheng)的(de)(de)(de)(de)(de)常(chang)開(kai)防(fang)(fang)火門(men)(men)(men)(men)(men)釋放(fang)裝(zhuang)置(zhi),它具有(you)使(shi)防(fang)(fang)火門(men)(men)(men)(men)(men)平時(shi)保(bao)持(chi)常(chang)開(kai),火災時(shi)能自動(dong)關閉(bi)的(de)(de)(de)(de)(de)功能,實現“斷電(dian)關門(men)(men)(men)(men)(men)”,平時(shi)可由(you)市電(dian)供電(dian),不占用有(you)限的(de)(de)(de)(de)(de)消(xiao)防(fang)(fang)電(dian)源資源,不增加消(xiao)防(fang)(fang)供電(dian)設備與回路成(cheng)(cheng)本(ben),發生火災時(shi)正好(hao)切斷市電(dian)供電(dian)實現自動(dong)關閉(bi),從而保(bao)證了(le)平時(shi)消(xiao)防(fang)(fang)通(tong)(tong)道(dao)的(de)(de)(de)(de)(de)暢(chang)通(tong)(tong)性,火災時(shi),更好(hao)的(de)(de)(de)(de)(de)實現防(fang)(fang)火門(men)(men)(men)(men)(men)“隔煙阻火”的(de)(de)(de)(de)(de)功效,從而保(bao)證了(le)人員及財物的(de)(de)(de)(de)(de)安(an)全(quan)性。
電磁門吸分類
電磁(ci)門(men)(men)吸(xi)根據不同的(de)(de)安(an)裝方(fang)式(shi)(shi),可(ke)以(yi)分(fen)為(wei)墻(qiang)(qiang)(qiang)式(shi)(shi)、地式(shi)(shi)、鏈(lian)(lian)式(shi)(shi)三類,地式(shi)(shi)電磁(ci)門(men)(men)吸(xi)由墻(qiang)(qiang)(qiang)式(shi)(shi)電磁(ci)門(men)(men)吸(xi)和直(zhi)角地面安(an)裝支(zhi)架(jia)組成(cheng),鏈(lian)(lian)式(shi)(shi)電磁(ci)門(men)(men)吸(xi)由墻(qiang)(qiang)(qiang)式(shi)(shi)電磁(ci)門(men)(men)吸(xi)和鏈(lian)(lian)條扣件組成(cheng)。一般墻(qiang)(qiang)(qiang)式(shi)(shi)門(men)(men)吸(xi)適用(yong)(yong)于門(men)(men)扇(shan)(shan)(shan)在(zai)較大開啟(qi)(qi)角度時離(li)墻(qiang)(qiang)(qiang)面的(de)(de)距(ju)(ju)離(li)很近的(de)(de)情(qing)況,地式(shi)(shi)電磁(ci)門(men)(men)吸(xi)則適用(yong)(yong)于門(men)(men)扇(shan)(shan)(shan)在(zai)開啟(qi)(qi)后(hou)背(bei)后(hou)無墻(qiang)(qiang)(qiang)因而無法使用(yong)(yong)墻(qiang)(qiang)(qiang)式(shi)(shi)的(de)(de)情(qing)況。鏈(lian)(lian)式(shi)(shi)門(men)(men)吸(xi)就比較適合(he)用(yong)(yong)于門(men)(men)扇(shan)(shan)(shan)在(zai)開啟(qi)(qi)后(hou)背(bei)后(hou)有墻(qiang)(qiang)(qiang)但(dan)距(ju)(ju)離(li)較遠的(de)(de)情(qing)況。所以(yi)選擇(ze)門(men)(men)吸(xi)種類的(de)(de)時候,應該根據門(men)(men)與墻(qiang)(qiang)(qiang)之間的(de)(de)距(ju)(ju)離(li)累(lei)確定使用(yong)(yong)哪一款(kuan)。
電磁門吸的正確安裝方法
首先,我們要(yao)確定門(men)(men)吸(xi)的(de)安裝方式以及選擇一款合(he)適(shi)的(de)門(men)(men)吸(xi)產品,之后在(zai)門(men)(men)和墻上選擇合(he)適(shi)的(de)安裝位置,然后將(jiang)(jiang)吸(xi)板(ban)正(zheng)(zheng)面(mian)與電(dian)磁體正(zheng)(zheng)面(mian)對(dui)正(zheng)(zheng)貼(tie)(tie)合(he),不要(yao)留有縫隙,否則會影響磁力。再然后,將(jiang)(jiang)不干膠貼(tie)(tie)紙(zhi)撕下,貼(tie)(tie)在(zai)吸(xi)板(ban)的(de)背(bei)面(mian),將(jiang)(jiang)吸(xi)板(ban)正(zheng)(zheng)面(mian)與電(dian)磁體正(zheng)(zheng)面(mian)對(dui)正(zheng)(zheng)貼(tie)(tie)合(he),再將(jiang)(jiang)門(men)(men)扇打開至(zhi)碰(peng)到吸(xi)板(ban)(底),稍用力,使吸(xi)板(ban)粘(zhan)上門(men)(men)扇,再用配備的(de)螺絲緊固即(ji)可(ke)。
