YFB3系列粉尘防爆型三相异步电动机
YFB3 Series High Efficency dust explosion-proof three phase induction motors
在工业生产过程中常常会产生许多固体的可燃性粉尘，除煤炭（煤，活性炭）外，还有金属加工（铝，镁，钛等），农副产品加工（面粉，可可，棉尘，亚麻，纤维），化工原料，合成材料（塑料，树脂，燃料等），化学药品（乙酸钠脂，阿司匹林，硬脂酸锌等），这些行业和部门的电力拖动都需要粉尘防爆电机。YFB3系列粉尘防爆型三相异步电动机（一下简称电动机）为鼠笼式三相异步电动机，电动机的防爆性能符合GB12476.1-2013《可燃性粉尘环境用电气设备 第1部分：通用要求》和GB12476.5-2013《可燃性粉尘环境用电气设备 第5部分：外壳保护性“tD”》，电动机的电气性能符合 Q/BSL320282002-2019《YFB3系列粉尘防爆型三相异步电动机技术条件（机座号63-355）》的规定。外壳防护等级分为为IP65.防爆标志为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℃.
