使用

首先檢查防(fang)爆(bao)撓性(xing)管框架、風(feng)葉有無(wu)變形(xing)，扇葉轉動(dong)是否靈活，有無(wu)磨(mo)擦現象。檢查所有緊(jin)固件是否齊全、擰緊(jin)，應(ying)有防(fang)爆(bao)合格證編號(hao)。線(xian)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓必須(xu)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)上額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓相符。用(yong)500V兆歐表檢查電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)的(de)(de)(de)絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻，其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻值若小于(yu)5MΩ,則應(ying)用(yong)烘(hong)干法(fa)或短路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)法(fa)進行(xing)干燥處理,使其(qi)絕緣(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻大于(yu)5MΩ。必須(xu)配用(yong)小型防(fang)爆(bao)開(kai)關(guan)作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)關(guan)，或將普(pu)通(tong)開(kai)關(guan)安(an)裝于(yu)室外無(wu)爆(bao)炸危險性(xing)的(de)(de)(de)地方。接電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜外徑應(ying)與(yu)密封(feng)圈相符，擰緊(jin)、壓緊(jin)螺(luo)母后應(ying)保證密封(feng)圈與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜間(jian)，密封(feng)圈與(yu)出線(xian)咀間(jian)無(wu)間(jian)隙(xi)，否則將失去隔爆(bao)性(xing)能。
