style="text-indent:25px">1．鍋爐水的取樣，鍋爐水樣品一般從汽包的連續(xù)排污管中取出，再引至冷卻器。取樣點(diǎn)應(yīng)盡量靠近排污管引出汽包的出口處，并盡量地裝在引出汽包后的前列個(gè)排污閥門(mén)之前。 2．給水的取樣給水的取樣點(diǎn)一般設(shè)在給水泵之后，省煤器之前的高壓給水管上，應(yīng)該是在給水管的垂直管路上接一小管，給水樣品由此引至取樣冷卻器。給水的取樣管應(yīng)設(shè)在給水加藥后足以混勻的位置上。 3．凝結(jié)水的取樣凝結(jié)水的取樣點(diǎn)一般設(shè)在凝結(jié)水泵出口處的凝結(jié)水管道上，不宜裝在凝結(jié)水泵入口處，因凝結(jié)水泵入口處的壓力低于大氣壓。 4．疏水的取樣疏水一般在疏水箱中取樣。取樣點(diǎn)通常設(shè)在距疏水箱底300mm左右處。 5 將蒸汽樣品通過(guò)取樣冷卻器，使其凝結(jié)成水。蒸汽取樣器中蒸汽流量一般為20-30kg/h。對(duì)樣品引出導(dǎo)管及冷卻器的要求，與水的取樣相同。煤粉取樣器可用于制粉系統(tǒng)一次風(fēng)送粉管道上煤粉取樣**設(shè)備。連云港隱臂式煤粉取樣裝置</p><p

1、取樣冷卻器拆卸前應(yīng)測(cè)量板束的壓緊長(zhǎng)度尺寸，做好記錄（重裝時(shí)應(yīng)按此尺寸）。 </p> <p> 2、密封墊片若粘在兩板片間的溝槽內(nèi)，此時(shí)需用螺絲刀小心地將其分開(kāi)，螺絲刀應(yīng)先從易剝開(kāi)的部位插入，然后沿其周邊進(jìn)行分離，切不可損壞冷卻器板片和密封墊片。 </p> <p> 3、拆卸鈦材的板片時(shí)，嚴(yán)禁與明火接觸，以防氧化。 </p> <p> 4、在拆除及清理過(guò)程中，要輕拿輕放，不能用力撞擊或振動(dòng)，以免損壞換熱板片及密封膠墊。 </p> <p> 5、取樣冷卻器清理時(shí)，決不能使用金屬刷刷洗，尤其是不銹鋼板片，以免造成板片表面劃傷，加速板片的腐蝕，如果板片上有污點(diǎn)或鐵銹時(shí)，可用去污粉清理。 </p> <p> 6、清洗用的清水，必須不含鹽、硫等成分。連云港爐水取樣冷卻裝置廠(chǎng)家</p><p
