噴吹系統簡況

噴(pen)吹系統的組成，脈(mo)沖(chong)閥(fa)(fa)(fa)A端(duan)接壓(ya)(ya)縮空(kong)氣(qi)氣(qi)包，B端(duan)接噴(pen)吹管(guan)，脈(mo)沖(chong)閥(fa)(fa)(fa)背壓(ya)(ya)室控(kong)(kong)制閥(fa)(fa)(fa)、控(kong)(kong)制閥(fa)(fa)(fa)動作(zuo)由(you)控(kong)(kong)制儀發出指令。在控(kong)(kong)制儀無(wu)信號輸出時，控(kong)(kong)制閥(fa)(fa)(fa)的活動鐵芯封住(zhu)排(pai)氣(qi)口，脈(mo)沖(chong)閥(fa)(fa)(fa)處于關閉狀態。當控(kong)(kong)制儀發出信號時，控(kong)(kong)制閥(fa)(fa)(fa)將脈(mo)沖(chong)背壓(ya)(ya)室與(yu)大氣(qi)相通，脈(mo)沖(chong)閥(fa)(fa)(fa)開啟(qi)，壓(ya)(ya)縮空(kong)氣(qi)由(you)氣(qi)包通過脈(mo)沖(chong)閥(fa)(fa)(fa)經(jing)噴(pen)吹管(guan)小(xiao)孔(kong)噴(pen)進文(wen)氏管(guan)，改(gai)成濾袋內瞬時正壓(ya)(ya)，實現清灰。
