噴吹系(xi)統簡況

噴(pen)吹系統(tong)的組成，脈(mo)沖(chong)閥(fa)(fa)A端接壓縮(suo)空氣(qi)氣(qi)包(bao)，B端接噴(pen)吹管，脈(mo)沖(chong)閥(fa)(fa)背壓室控(kong)制(zhi)(zhi)閥(fa)(fa)、控(kong)制(zhi)(zhi)閥(fa)(fa)動(dong)作(zuo)由控(kong)制(zhi)(zhi)儀發(fa)出指(zhi)令。在控(kong)制(zhi)(zhi)儀無信號輸出時(shi)(shi)，控(kong)制(zhi)(zhi)閥(fa)(fa)的活動(dong)鐵芯封住排氣(qi)口(kou)，脈(mo)沖(chong)閥(fa)(fa)處于關(guan)閉狀態。當控(kong)制(zhi)(zhi)儀發(fa)出信號時(shi)(shi)，控(kong)制(zhi)(zhi)閥(fa)(fa)將(jiang)脈(mo)沖(chong)背壓室與大(da)氣(qi)相通，脈(mo)沖(chong)閥(fa)(fa)開啟，壓縮(suo)空氣(qi)由氣(qi)包(bao)通過脈(mo)沖(chong)閥(fa)(fa)經噴(pen)吹管小孔(kong)噴(pen)進(jin)文氏管，改成濾(lv)袋(dai)內瞬時(shi)(shi)正(zheng)壓，實現清灰(hui)。
