  关于搪(tang)瓷管空气(qi)预热器(qi)的安(an)装要求(qiu),有很(hen)多人(ren)问小编,接下(xia)来(lai)就由J9九游会AG 为大家解(jie)答一下(xia)吧(ba),不知(zhi)道的朋(peng)友,还不看过来(lai)?
  1.定(ding)位(wei)搪(tang)瓷管(guan)空气(qi)预(yu)热(re)(re)器(qi)的(de)(de)(de)(de)中(zhong)(zhong)(zhong)须与底(di)(di)梁扇形板的(de)(de)(de)(de)中(zhong)(zhong)(zhong)心(xin)线的(de)(de)(de)(de)交(jiao)点相(xiang)重(zhong)合。搪(tang)瓷管(guan)是涂烧在(zai)金属(shu)底(di)(di)坯表(biao)面上的(de)(de)(de)(de)无机玻璃瓷釉(you),在(zai)金属(shu)表(biao)面进行瓷釉(you)涂搪(tang)可以防止金属(shu)生锈,使金属(shu)在(zai)受(shou)热(re)(re)时(shi)不至(zhi)于在(zai)表(biao)面形成氧(yang)化(hua)层并且能抵抗各种液体的(de)(de)(de)(de)侵蚀。安装时(shi),用(yong)(yong)细钢(gang)丝确定(ding)空气(qi)预(yu)热(re)(re)器(qi)纵横中(zhong)(zhong)(zhong)心(xin)线的(de)(de)(de)(de)交(jiao)点,再用(yong)(yong)线锤来(lai)确定(ding)搪(tang)瓷管(guan)空气(qi)预(yu)热(re)(re)器(qi)的(de)(de)(de)(de)具(ju)体位(wei)置,标高应根据图纸(zhi)来(lai)确定(ding)。底(di)(di)部(bu)轴承中(zhong)(zhong)(zhong)心(xin)与底(di)(di)部(bu)扇形板几何中(zhong)(zhong)(zhong)心(xin)线相(xiang)对偏差要求小于等于2mm。
  2.调(diao)(diao)整搪瓷(ci)(ci)管空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi)水平(ping)度(du)(du)搪瓷(ci)(ci)管空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi)的(de)水平(ping)度(du)(du)如(ru)何(he),对轴承的(de)使用的(de)时长有很大影响。搪瓷(ci)(ci)管常用来做空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi),可(ke)分(fen)为内涂和(he)外涂两种。搪瓷(ci)(ci)管空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi)回转式预(yu)(yu)热器(qi)(qi)的(de)工作原理是:预(yu)(yu)热器(qi)(qi)转子部件由数万计(ji)的(de)传(chuan)热元(yuan)件组成,当空(kong)(kong)预(yu)(yu)器(qi)(qi)缓慢(man)旋转,烟(yan)(yan)气(qi)和(he)空(kong)(kong)气(qi)逆向交替流经空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi)。蓄热元(yuan)件在(zai)烟(yan)(yan)气(qi)侧(ce)吸(xi)热,在(zai)空(kong)(kong)气(qi)侧(ce)放热,从而达到降低(di)锅炉排烟(yan)(yan)温(wen)度(du)(du),提高热风温(wen)度(du)(du)的(de)预(yu)(yu)热作用。因此,须用框式水平(ping)仪调(diao)(diao)整搪瓷(ci)(ci)管空(kong)(kong)气(qi)预(yu)(yu)热器(qi)(qi)的(de)水平(ping)度(du)(du),直至符合(he)设计(ji)要求(qiu)。
  3.清洗搪瓷管空气预热器(qi)一般用(yong)清洗(xi)剂或煤油。清洗(xi)后,要及(ji)时用(yong)帆布覆盖,严禁杂物掉入(ru)轴(zhou)承内(nei)部。
