粉體氣力輸送機管(guan)道疏(shu)通時(shi)應注(zhu)意(yi)哪些問題(ti)？粉(fen)(fen)體(ti)氣力(li)輸送(song)(song)機采用密(mi)封(feng)管(guan)道輸送(song)(song)物(wu)料。在(zai)運輸過程中，由于物(wu)料特(te)性、氣流(liu)等(deng)原因(yin)(yin)，可(ke)能會發(fa)生物(wu)料堵塞(sai)，管(guan)道空間有(you)限且密(mi)封(feng)，因(yin)(yin)此在(zai)疏(shu)通和清理方面(mian)會有(you)很多不便。粉(fen)(fen)體(ti)氣力(li)輸送(song)(song)機管(guan)道疏(shu)通時(shi)應注(zhu)意(yi)哪些問題(ti)？

        1、由于采用低速推流式氣力輸送系統氣力輸送機，一般情況下一臺(tai)鍋爐需要配備兩條以上(shang)的輸(shu)送管(guan)(guan)路，所以可以采用正(zheng)吹反吸(xi)的方式(shi)疏通(tong)(tong)管(guan)(guan)路設備。使用氣力輸(shu)送泵裝(zhuang)置疏通(tong)(tong)輸(shu)送管(guan)(guan)道(dao)比使用供氣環疏通(tong)(tong)輸(shu)送管(guan)(guan)路具有更大(da)的疏通(tong)(tong)效果，疏通(tong)(tong)速度快。

        2、管道始(shi)端安裝氣動(dong)正(zheng)吹蝶閥、氣動(dong)反抽球閥和(he)管道壓力開關組成疏通管道裝置，由PLC程序控制。

        3、當輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)壓(ya)(ya)力開關(guan)輸(shu)出超(chao)高信號時，關(guan)閉L型倉(cang)(cang)泵氣動(dong)(dong)進(jin)(jin)(jin)氣閥(fa)，打(da)(da)開氣動(dong)(dong)反(fan)抽(chou)球(qiu)閥(fa)，利用尾部煙道負(fu)壓(ya)(ya)鍋爐對輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)中的干(gan)灰進(jin)(jin)(jin)行(xing)(xing)反(fan)抽(chou)。此時如果(guo)輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)內的壓(ya)(ya)力還沒(mei)有下(xia)降到正(zheng)(zheng)常值，關(guan)閉反(fan)吸氣動(dong)(dong)球(qiu)閥(fa)，打(da)(da)開氣動(dong)(dong)正(zheng)(zheng)吹(chui)蝶(die)閥(fa)，用壓(ya)(ya)縮空氣對輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)加壓(ya)(ya)進(jin)(jin)(jin)行(xing)(xing)氣動(dong)(dong)輸(shu)送(song)。正(zheng)(zheng)吹(chui)時間為90s。反(fan)復進(jin)(jin)(jin)行(xing)(xing)反(fan)抽(chou)正(zheng)(zheng)吹(chui)動(dong)(dong)作，直至輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)壓(ya)(ya)力恢(hui)復正(zheng)(zheng)常，輸(shu)送(song)管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)壓(ya)(ya)力開關(guan)輸(shu)出信號自動(dong)(dong)取消管(guan)(guan)(guan)道疏通程序(xu)，恢(hui)復L型管(guan)(guan)(guan)路(lu)(lu)(lu)(lu)正(zheng)(zheng)常運行(xing)(xing)程序(xu)倉(cang)(cang)庫泵送(song)貨。

       4、輸送系統正(zheng)常運行時(shi)，氣動正(zheng)吹蝶閥和氣動反(fan)吸(xi)球閥處于關閉狀(zhuang)態。
