貴陽鍋爐除塵氣力輸送設備-管粉狀物料氣力輸送螺旋泵
在傳統的(de)氣力輸(shu)送系(xi)統中，輸(shu)送管(guan)(guan)道的(de)彎頭應(ying)采用(yong)耐磨材料制成。管(guan)(guan)道應(ying)設有固定支架和滑(hua)動(dong)支架。管(guan)(guan)段之間(jian)的(de)接(jie)口以及管(guan)(guan)子和閥門之間(jian)的(de)連接(jie)處應(ying)光滑(hua)，無凹(ao)凸不平。因此，對安裝(zhuang)運輸(shu)管(guan)(guan)道的(de)要求非常高(gao)，具體如下：
1、粉體氣力輸送機輸送(song)管道轉彎(wan)半徑一般為1.5米(mi)(mi)，zui小標準(zhun)為1.0米(mi)(mi)。輸送(song)管道的(de)彎(wan)頭(tou)一般應采(cai)用耐磨材料(liao)。
2、輸送管(guan)道(dao)(dao)可(ke)(ke)在水平(ping)面上任意回轉，并可(ke)(ke)垂直(zhi)升降(jiang)。在輸送管(guan)道(dao)(dao)末端，可(ke)(ke)垂直(zhi)向(xiang)下布(bu)置。當輸送管(guan)道(dao)(dao)因地形條件必須傾斜布(bu)置時，傾斜角(jiao)度不能(neng)大(da)于5°。
3、輸送(song)管道從(cong)支管與主管連(lian)接(jie)時，一般宜采用水(shui)平連(lian)接(jie)或自上(shang)(shang)而下(xia)(xia)連(lian)接(jie)的(de)方(fang)法(fa)。不宜采用自下(xia)(xia)而上(shang)(shang)的(de)連(lian)接(jie)方(fang)式(shi)，也不宜采用先(xian)垂直向下(xia)(xia)再水(shui)平運輸的(de)布置方(fang)式(shi)。
4、布置相同(tong)管(guan)徑的輸送(song)管(guan)道時，管(guan)道水平(ping)(ping)段長度不宜大于300m。當水平(ping)(ping)管(guan)道長度超過200m時，可(ke)采用改變(bian)輸送(song)方向(xiang)的布置。
5、輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)管(guan)道(dao)各段之間以及(ji)管(guan)道(dao)與(yu)閥門連接之間的(de)接口應(ying)保持(chi)光滑，不應(ying)有凹凸不平(ping)的(de)現象。我(wo)們的(de)氣力輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)泵(beng)的(de)輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)距(ju)離太長。當輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)量(liang)較大(da)時，所需的(de)熟料(liao)管(guan)道(dao)直徑過大(da)，會(hui)(hui)給管(guan)道(dao)系統的(de)布置和安裝(zhuang)帶來不便，并造成初期投資過高。料(liao)封泵(beng)利(li)用(yong)低壓氣流(liu)的(de)能(neng)量(liang)。它利(li)用(yong)空氣源(yuan)在真空中輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)材(cai)料(liao)。分為稀相(xiang)、密相(xiang)和負壓輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)方式(shi)。料(liao)封泵(beng)采用(yong)稀相(xiang)和密相(xiang)組(zu)合輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)方式(shi)。輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)物料(liao)時，可在泵(beng)體內輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)物料(liao)。在輸(shu)(shu)(shu)(shu)送(song)(song)(song)(song)(song)過程(cheng)中，能(neng)夠充分保證(zheng)生產環境(jing)的(de)衛(wei)生，粉煤灰不會(hui)(hui)外溢(yi)，大(da)大(da)提高了產量(liang)。
