河南粉狀物石灰石粉料封泵-粉體氣力輸送機料封泵如何進行連續輸送？
粉體氣力輸送機料(liao)封(feng)泵(beng)如何(he)進行連(lian)續輸(shu)送？
氣(qi)(qi)力輸(shu)送(song)(song)料(liao)封泵(beng)是一種連續粉體(ti)(ti)輸(shu)送(song)(song)的設備(bei)。由于(yu)料(liao)封泵(beng)的工(gong)作原理，進(jin)(jin)料(liao)、輸(shu)送(song)(song)和卸料(liao)都(dou)非常(chang)簡單(dan)，因此料(liao)封泵(beng)在使用中非常(chang)常(chang)用。粉體(ti)(ti)氣(qi)(qi)力輸(shu)送(song)(song)系(xi)統投入運行(xing)(xing)后(hou)，排(pai)氣(qi)(qi)閥、上泵(beng)送(song)(song)料(liao)閥、預關閥依次打開(kai)，上泵(beng)進(jin)(jin)入送(song)(song)料(liao)階段。當料(liao)位達到一定(ding)高度時，上泵(beng)料(liao)位計發出信號，并設定(ding)時間控制。為了進(jin)(jin)行(xing)(xing)粉體(ti)(ti)的連續氣(qi)(qi)力輸(shu)送(song)(song)，我們依次關閉進(jin)(jin)料(liao)閥和排(pai)氣(qi)(qi)閥。這(zhe)樣就完成了一次完整的粉體(ti)(ti)輸(shu)送(song)(song)。
在此(ci)過(guo)(guo)程中，料(liao)位計是(shi)主要控(kong)制部(bu)件，加料(liao)時(shi)間(jian)控(kong)制是(shi)備(bei)用措施。只要料(liao)位達到或加料(liao)時(shi)間(jian)到期，加料(liao)閥就(jiu)會自(zi)動(dong)(dong)關(guan)閉。下(xia)(xia)部(bu)泵(beng)(beng)送(song)料(liao)。當下(xia)(xia)泵(beng)(beng)料(liao)位達到低(di)(di)限時(shi)，下(xia)(xia)料(liao)料(liao)封(feng)泵(beng)(beng)體(ti)低(di)(di)料(liao)位計發(fa)出料(liao)空信號。此(ci)時(shi)，平衡閥和上(shang)泵(beng)(beng)壓力閥打開。延(yan)遲X秒后，下(xia)(xia)部(bu)泵(beng)(beng)進(jin)水(shui)閥打開。下(xia)(xia)泵(beng)(beng)進(jin)入進(jin)料(liao)階段。延(yan)遲XX秒后，充電過(guo)(guo)程結束。依次關(guan)閉加料(liao)閥、壓力閥、平衡閥，加料(liao)過(guo)(guo)程結束。連(lian)續輸(shu)送(song)。系(xi)統啟(qi)動(dong)(dong)后，連(lian)續輸(shu)送(song)泵(beng)(beng)起到送(song)料(liao)和送(song)料(liao)泵(beng)(beng)的作用。下(xia)(xia)旋轉送(song)料(liao)器始(shi)終處(chu)于運行狀態(tai)。此(ci)時(shi)，如果下(xia)(xia)泵(beng)(beng)體(ti)處(chu)于空泵(beng)(beng)狀態(tai)，則會自(zi)動(dong)(dong)切換到加料(liao)狀態(tai)，輸(shu)送(song)管道此(ci)時(shi)為(wei)空載(zai)輸(shu)送(song)。
當氣力輸送機連(lian)續(xu)料(liao)封(feng)泵(beng)完成一個給(gei)料(liao)周期(qi)后(hou)，系(xi)統切換到負載運行，給(gei)料(liao)機實(shi)現均勻連(lian)續(xu)給(gei)料(liao)，底(di)部混合(he)送(song)(song)(song)料(liao)裝(zhuang)置負責將粉料(liao)與壓(ya)縮空氣(qi)混合(he)后(hou)氣(qi)力輸(shu)送(song)(song)(song)至鍋爐爐膛(tang)。對于(yu)管(guan)(guan)道(dao)(dao)吹(chui)掃，在輸(shu)送(song)(song)(song)管(guan)(guan)道(dao)(dao)的(de)起始端安裝(zhuang)壓(ya)力變(bian)送(song)(song)(song)器，以監測管(guan)(guan)道(dao)(dao)內(nei)的(de)輸(shu)送(song)(song)(song)壓(ya)力。當管(guan)(guan)道(dao)(dao)內(nei)壓(ya)力達(da)到上(shang)限(xian)時，系(xi)統啟(qi)動吹(chui)氣(qi)閥(fa)，增(zeng)(zeng)加注入的(de)壓(ya)縮空氣(qi)量(liang)。通(tong)過增(zeng)(zeng)加輸(shu)送(song)(song)(song)風量(liang)、降低輸(shu)送(song)(song)(song)混合(he)比，將管(guan)(guan)道(dao)(dao)堵塞(sai)消除在萌(meng)芽狀態(tai)。爐前封(feng)料(liao)泵(beng)、分配器管(guan)(guan)道(dao)(dao)及輸(shu)送(song)(song)(song)管(guan)(guan)道(dao)(dao)采(cai)用20#無(wu)縫鋼(gang)管(guan)(guan)，彎頭處采(cai)用耐(nai)磨復合(he)陶(tao)瓷(ci)管(guan)(guan)，以提高其(qi)耐(nai)磨性和(he)壽命。分配器內(nei)部采(cai)用耐(nai)磨材料(liao)制作，出(chu)口支(zhi)路管(guan)(guan)線設(she)有手動調節閥(fa)和(he)氣(qi)動快關閥(fa)。
