  接下来,小编也废话少说,就严明扼要(yao)的(de)为大家介绍(shao)搪瓷(ci)管空气预热器的安装要求。
  1.定(ding)位(wei)搪(tang)瓷(ci)管(guan)(guan)空(kong)气(qi)(qi)预(yu)热(re)器的中(zhong)心须与底梁(liang)扇形(xing)板的中(zhong)心线(xian)的交点(dian)相(xiang)重合。搪(tang)瓷(ci)管(guan)(guan)是涂烧(shao)在金(jin)(jin)属(shu)(shu)底坯表(biao)面上的无机(ji)玻璃瓷(ci)釉,在金(jin)(jin)属(shu)(shu)表(biao)面进行(xing)瓷(ci)釉涂搪(tang)可以(yi)防止金(jin)(jin)属(shu)(shu)生锈,使金(jin)(jin)属(shu)(shu)在受热(re)时不(bu)至于在表(biao)面形(xing)成氧(yang)化层并且能抵抗各种(zhong)液体(ti)的侵蚀。安装时,用细钢丝确(que)定(ding)空(kong)气(qi)(qi)预(yu)热(re)器纵横中(zhong)心线(xian)的交点(dian),再用线(xian)锤(chui)来(lai)确(que)定(ding)搪(tang)瓷(ci)管(guan)(guan)空(kong)气(qi)(qi)预(yu)热(re)器的具体(ti)位(wei)置,标高应(ying)根据(ju)图纸来(lai)确(que)定(ding)。底部轴承(cheng)中(zhong)心与底部扇形(xing)板几何中(zhong)心线(xian)相(xiang)对偏差要求小于等于2mm。
  2.调整(zheng)搪(tang)瓷管空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi)水(shui)平(ping)(ping)度(du)搪(tang)瓷管空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi)的(de)水(shui)平(ping)(ping)度(du)如何,对轴承的(de)使用的(de)时(shi)长(zhang)有很大影响。搪(tang)瓷管常用来做空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi),可分为内涂和(he)外涂两种。搪(tang)瓷管空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi)回转(zhuan)式预(yu)(yu)热(re)(re)器(qi)(qi)(qi)的(de)工作原理是:预(yu)(yu)热(re)(re)器(qi)(qi)(qi)转(zhuan)子部件(jian)由数(shu)万计(ji)的(de)传(chuan)热(re)(re)元件(jian)组成(cheng),当空(kong)(kong)(kong)预(yu)(yu)器(qi)(qi)(qi)缓慢旋(xuan)转(zhuan),烟气(qi)(qi)和(he)空(kong)(kong)(kong)气(qi)(qi)逆向交(jiao)替流经空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi)。蓄热(re)(re)元件(jian)在烟气(qi)(qi)侧吸热(re)(re),在空(kong)(kong)(kong)气(qi)(qi)侧放热(re)(re),从而达(da)到降低(di)锅炉排烟温度(du),提高(gao)热(re)(re)风温度(du)的(de)预(yu)(yu)热(re)(re)作用。因此,须用框式水(shui)平(ping)(ping)仪(yi)调整(zheng)搪(tang)瓷管空(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)(qi)(qi)的(de)水(shui)平(ping)(ping)度(du),直(zhi)至符(fu)合设计(ji)要求。
  3.清(qing)(qing)洗(xi)搪瓷管空气预热设备一般用(yong)清(qing)(qing)洗(xi)剂或煤油。清(qing)(qing)洗(xi)后,要及时用(yong)帆布覆(fu)盖,严禁杂物掉入轴承内部。
