Element 1: Certificate of conformity - the formal electric rolling door has the inspection certificate issued by the legal inspection organization and the production certificate of safety technology prevention products issued by the safety technology Prevention Department of the provincial public security department (bureau) where the manufacturer is located.

要素2:等級(jí)——等級(jí)電動(dòng)卷簾門(mén)分為A、B、C3級(jí)。C級(jí)防盜性能高,B級(jí)其次,A級(jí)低,市面上多為A級(jí),普遍適用于一般家庭。A級(jí)要求:全鋼質(zhì)、平開(kāi)全封閉式,普通機(jī)械手工工具與便攜式電動(dòng)工具相互作用下,其薄弱環(huán)夠抵抗非正常開(kāi)啟的凈時(shí)間≥15分,或應(yīng)不能切割出一個(gè)穿透門(mén)體的615平方厘米的洞口。

Element 2: Level - safety level the safety of electric rolling shutter door is divided into levels a, B and C3. Class C has high anti-theft performance, followed by class B, and class A is low. Most of them are class A on the market, which is generally applicable to ordinary families. Class a requirements: all steel, flat open and fully enclosed. Under the interaction of ordinary mechanical hand tools and portable electric tools, the net time for the weak link to resist abnormal opening shall be ≥ 15 minutes, or a 615 square centimeter hole penetrating the door body shall not be cut.

要素3:材質(zhì)——材質(zhì)目前較普遍用不銹鋼,美觀(guān)、耐用、防銹蝕。主要看兩點(diǎn):①牌號(hào)現(xiàn)流行的不銹鋼電動(dòng)卷簾門(mén)材質(zhì)以牌號(hào)302、304為主;②鋼板厚度門(mén)框鋼板厚度不小于2cm,門(mén)扇前后面鋼板厚度一般在0.8cm～1cm之間,門(mén)扇內(nèi)部設(shè)有骨架和加強(qiáng)板。

Element 3: material - at present, stainless steel is widely used, which is beautiful, durable and anti-corrosion. There are two main points: ① the popular stainless steel electric rolling shutter doors are mainly made of grades 302 and 304; ② The thickness of steel plate is not less than 2cm for the door frame. The thickness of steel plate at the front and back of the door leaf is generally between 0.8cm and 1cm. The door leaf is internally provided with framework and reinforcing plate.

要素4:功能——電動(dòng)卷簾門(mén)是否支持手動(dòng)功能,手動(dòng)要方便,快捷。停電時(shí)將離合扭轉(zhuǎn)90度,即可手推運(yùn)行。電動(dòng)卷簾門(mén)不能存在慣性滑行的現(xiàn)象,要具有雙面自動(dòng)卡鎖功能。為了提高電動(dòng)卷簾門(mén)運(yùn)行平穩(wěn)程度,要增強(qiáng)拉力,所以需要采用的是8輪前后驅(qū)動(dòng),連排齒輪轉(zhuǎn)動(dòng)的生產(chǎn)安裝技術(shù)。

Element 4: function - whether the electric rolling shutter door supports manual function, which should be convenient and fast. In case of power failure, turn the clutch 90 degrees to manually push it. The electric rolling shutter door shall not have the phenomenon of inertial sliding, and shall have the function of double-sided automatic locking. In order to improve the running stability of the electric rolling shutter door and enhance the tension, the production and installation technology of 8-wheel front and rear drive and continuous gear rotation needs to be adopted.

要素5:結(jié)構(gòu)——觀(guān)察電動(dòng)卷簾 門(mén)的結(jié)構(gòu)是否精密,潤(rùn)滑程度好壞,好的電動(dòng)卷簾門(mén)散熱比較,采用全齒輪轉(zhuǎn)動(dòng),無(wú)鏈條、無(wú)皮帶,進(jìn)而增強(qiáng)了卷簾門(mén)機(jī)芯整體壽命。

Element 5: structure - observe whether the structure of the electric rolling shutter door is precise and whether the lubrication degree is good or not. A good electric rolling shutter door has better heat dissipation. It adopts full gear rotation without chain and belt, so as to enhance the overall service life of the rolling shutter door movement.
