①. 氣(qi)力輸(shu)送(song)介質管道的布置(zhi)應(ying)使管道短，彎頭數(shu)量少。水平管段不(bu)宜過長，且(qie)管道不(bu)得(de)有死角(jiao)和“袋(dai)形”出現。


②. 氣力輸送(song)介質管(guan)道(dao)的布置應(ying)采用大曲(qu)率(lv)半徑的彎管(guan)，彎管(guan)的曲(qu)率(lv)半徑應(ying)根據輸送(song)方(fang)(fang)式、物料的特性、工藝要求(qiu)和流(liu)動(dong)方(fang)(fang)向確定，且應(ying)滿足PID或風送(song)系(xi)統制造商的要求(qiu)。


③. 在供料(liao)器后(hou)的氣力輸送介質管(guan)道應(ying)設置一段直管(guan)段，直管(guan)段的長度應(ying)滿足(zu)PID或風送系統制造商的要求。


④. 氣力輸送管(guan)道的水(shui)(shui)平走(zou)向直(zhi)管(guan)段(duan)不宜(yi)太長。當水(shui)(shui)平直(zhi)管(guan)段(duan)較(jiao)長時，應在水(shui)(shui)平管(guan)段(duan)中間(jian)加一段(duan)垂直(zhi)管(guan)段(duan)，然(ran)后管(guan)道繼(ji)續水(shui)(shui)平走(zou)向。


⑤. 氣力輸送介質管道應有可靠的靜電接(jie)地設(she)施，管道上的法蘭宜跨接(jie)。


⑥. 氣力輸送管(guan)(guan)(guan)道(dao)應滿足(zu)操作、安裝、檢修、事(shi)故處理的要(yao)求(qiu)，在垂直管(guan)(guan)(guan)道(dao)的下部或(huo)水(shui)平(ping)管(guan)(guan)(guan)道(dao)的適當部位應設置拆卸短管(guan)(guan)(guan)，供管(guan)(guan)(guan)道(dao)堵(du)塞時清料使用。


⑦. 對氣力輸送管(guan)道系統的管(guan)道，必須設置牢固(gu)的管(guan)支(zhi)架。設計時(shi)(shi)不僅要考(kao)慮(lv)支(zhi)承其全部重(zhong)量(liang)，同時(shi)(shi)還應考(kao)慮(lv)其振動因素。


⑧. 氣力輸送系(xi)(xi)統(tong)應(ying)有粉塵防爆措(cuo)施，對風送系(xi)(xi)統(tong)內各種設(she)備的排(pai)氣口，都應(ying)接到(dao)除塵系(xi)(xi)統(tong)，不得有粉塵在裝置內泄漏。


⑨. 所有(you)氣流輸送管(guan)道的(de)端(duan)部(bu)焊接前必須采用機(ji)械(xie)加工。所有(you)管(guan)道端(duan)部(bu)的(de)坡口應打磨光滑、無毛(mao)刺、銳角。
