一、屏蔽門的分類有哪些
屏蔽門主要有以下幾種:
1、全自動屏蔽門:電動(dong)(dong)(dong)機作(zuo)為驅動(dong)(dong)(dong)源,帶動(dong)(dong)(dong)蝸輪(lun)、蝸桿機構實(shi)現門的(de)(de)開(kai)啟(qi)、關閉(bi)的(de)(de)旋轉動(dong)(dong)(dong)作(zuo);相(xiang)對其他液壓或氣動(dong)(dong)(dong)的(de)(de)傳動(dong)(dong)(dong)方(fang)式全機械式傳動(dong)(dong)(dong)可(ke)靠性較好,同(tong)(tong)時(shi)(shi)噪聲小(xiao),無(wu)污(wu)染。門框(kuang)上設有密碼鎖(suo)(suo)(suo)或IC卡門鎖(suo)(suo)(suo),同(tong)(tong)時(shi)(shi)能與各(ge)種(zhong)門禁系(xi)統(tong)相(xiang)連,協同(tong)(tong)電動(dong)(dong)(dong)鎖(suo)(suo)(suo)緊(jin)來自動(dong)(dong)(dong)實(shi)現門的(de)(de)開(kai)啟(qi)和關閉(bi),節省了人力。
2、電動鎖緊屏蔽門:屏蔽性能高、穩定,但門的閉(bi)合與開(kai)啟比(bi)較笨重。采用全機械(xie)式傳動(dong)(dong)(dong)(dong)(dong)。電動(dong)(dong)(dong)(dong)(dong)機作為驅動(dong)(dong)(dong)(dong)(dong)源,整個減速、旋(xuan)轉運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)轉換為往(wang)復(fu)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)、斜面(mian)(mian)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)等全部(bu)采用機械(xie)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)實(shi)現。由齒(chi)輪齒(chi)條(tiao)傳遞的往(wang)復(fu)運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong),通(tong)過斜面(mian)(mian)機構實(shi)現門的鎖閉(bi)和開(kai)啟,運(yun)(yun)(yun)動(dong)(dong)(dong)(dong)(dong)平(ping)穩、無噪聲。人力空旋(xuan)轉門扇達一(yi)設定的角(jiao)度后,觸動(dong)(dong)(dong)(dong)(dong)啟閉(bi)信號實(shi)現門的啟閉(bi)。
3、氣動式平移屏蔽門:具(ju)有多種控(kong)制功能(neng)、操(cao)作輕(qing)便、工作可(ke)(ke)靠等的特點(dian),尤其是開(kai)關的過(guo)程不占屏蔽室(shi)的使用(yong)(yong)空間(jian),適用(yong)(yong)于焊接式(shi)或組裝式(shi)屏蔽室(shi)。具(ju)有全自動(dong)(IC卡控(kong)制)、半自動(dong)(按鈕控(kong)制)及(ji)手動(dong)等多種控(kong)制方式(shi);防擠壓(ya)控(kong)制;自動(dong)電氣控(kong)制;采用(yong)(yong)先進(jin)、可(ke)(ke)靠的邏輯電路實現全自動(dong)控(kong)制,并可(ke)(ke)定制控(kong)制邏輯。
二、屏蔽門有什么選購技巧
在選購屏蔽門時,需要考慮以下(xia)幾個方(fang)面:
1、場地環境:不同的(de)場地環境(jing)需要選擇(ze)不同類型(xing)的(de)屏蔽門(men)。比(bi)如(ru)狹窄(zhai)的(de)門(men)口要選擇(ze)平移門(men),大型(xing)商(shang)場要選擇(ze)旋轉門(men)。
2、門禁系統:屏蔽門(men)(men)需要與門(men)(men)禁(jin)系統配合(he)使用,因此(ci)在選購時(shi)需考慮(lv)門(men)(men)禁(jin)系統的接口類型和通(tong)訊(xun)協議是否兼容。
3、材質選擇:屏蔽門的材料(liao)一般有(you)不銹鋼、鋁合金(jin)、玻璃等。不銹鋼材質(zhi)的門扇表面硬度高、不易磨(mo)損(sun);鋁合金(jin)材質(zhi)的門扇表面光(guang)潔(jie)美觀、不易受氧化腐蝕。
4、性能要求:屏蔽(bi)門需要具(ju)備緊密密閉(bi)、使用平穩(wen)、啟(qi)閉(bi)順暢等(deng)性能要求。
5、安全性能:屏(ping)蔽門需要(yao)防止(zhi)非法進入,因此在選擇時要(yao)考慮(lv)它的安全(quan)性能,防止(zhi)猝(cu)發事件的發生。
