YFB3系列粉塵防爆型三相異步電動(dòng)機(jī)

在工業(yè)生產(chǎn)過(guò)程中常常會(huì)產(chǎn)生許多固體的可燃性粉塵，除煤炭（煤，活性炭）外，還有金屬加工（鋁，鎂，鈦等），農(nóng)副產(chǎn)品加工（面粉，可可，棉塵，亞麻，纖維），化工原料，合成材料（塑料，樹(shù)脂，燃料等），化學(xué)藥品（乙酸鈉脂，阿司匹林，硬脂酸鋅等），這些行業(yè)和部門(mén)的電力拖動(dòng)都需要粉塵防爆電機(jī)。YFB3系列粉塵防爆型三相異步電動(dòng)機(jī)（一下簡(jiǎn)稱(chēng)電動(dòng)機(jī)）為鼠籠式三相異步電動(dòng)機(jī)，電動(dòng)機(jī)的防爆性能符合GB12476.1-2013《可燃性粉塵環(huán)境用電氣設(shè)備 第1部分：通用要求》和GB12476.5-2013《可燃性粉塵環(huán)境用電氣設(shè)備 第5部分：外殼保護(hù)性“tD”》，電動(dòng)機(jī)的電氣性能符合 Q/BSL320282002-2019《YFB3系列粉塵防爆型三相異步電動(dòng)機(jī)技術(shù)條件（機(jī)座號(hào)63-355）》的規(guī)定。外殼防護(hù)等級(jí)分為為IP65.防爆標(biāo)志為ExtD A21 IP65 T130℃。

In the industrial production process, many solid combustible dusts are often produced. In addition to coal (coal, activated carbon), there are also metal processing (aluminum, magnesium, titanium, etc.), agricultural and sideline product processing (flour, cocoa, cotton dust, flax, etc.) Fibers), chemical raw materials, synthetic materials (plastics, resins, fuels, etc.), chemicals (sodium acetate, aspirin, zinc stearate, etc.), dust explosion-proof motors are needed for electric drives in these industries and sectors. YFB3 series dust explosion-proof three-phase asynchronous motors (hereinafter referred to as motors) are squirrel-cage three-phase asynchronous motors. The explosion-proof performance of the motor complies with GB12476.1-2013 “Electrical Equipment for Combustible Dust Environment Part 1: General Requirements” and GB12476 .5-2013 “Electrical Equipment for Combustible Dust Environment Part 5: Shell Protection “tD””, the electrical performance of the motor meets Q/BSL320282002-2019 “YFB3 series dust explosion-proof three-phase asynchronous motor technical conditions (frame number) 63-355)”. The enclosure protection grade is divided into IP65. The explosion-proof mark is ExtD A21 IP65 T130℃.
