       接下来,小编(bian)也废话少说,就严明扼要的(de)为大(da)家介绍搪瓷管(guan)空气预(yu)热器的安装要求。
  1.定位搪瓷(ci)管空气预(yu)(yu)热(re)器(qi)(qi)的中(zhong)心(xin)(xin)须(xu)与底梁扇(shan)(shan)形板的中(zhong)心(xin)(xin)线的交(jiao)点(dian)相(xiang)重(zhong)合。搪瓷(ci)管是(shi)涂烧在(zai)金(jin)属底坯表面上的无机玻璃瓷(ci)釉,在(zai)金(jin)属表面进行瓷(ci)釉涂搪可以防止金(jin)属生锈,使(shi)金(jin)属在(zai)受热(re)时不至于在(zai)表面形成氧化层并(bing)且能抵抗各(ge)种液(ye)体(ti)的侵蚀(shi)。安装(zhuang)时,用细钢丝确定空气预(yu)(yu)热(re)器(qi)(qi)纵横中(zhong)心(xin)(xin)线的交(jiao)点(dian),再用线锤来(lai)确定搪瓷(ci)管空气预(yu)(yu)热(re)器(qi)(qi)的具体(ti)位置,标高应根据图纸来(lai)确定。底部轴承中(zhong)心(xin)(xin)与底部扇(shan)(shan)形板几何(he)中(zhong)心(xin)(xin)线相(xiang)对偏差要求小于等(deng)于2mm。
  2.调(diao)整搪(tang)瓷(ci)管(guan)(guan)(guan)空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)水(shui)(shui)平(ping)(ping)(ping)度(du)搪(tang)瓷(ci)管(guan)(guan)(guan)空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)水(shui)(shui)平(ping)(ping)(ping)度(du)如何(he),对轴承(cheng)的(de)(de)(de)使用(yong)的(de)(de)(de)时长(zhang)有很大影响。搪(tang)瓷(ci)管(guan)(guan)(guan)常(chang)用(yong)来(lai)做(zuo)空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi),可分为内涂(tu)和外涂(tu)两种(zhong)。搪(tang)瓷(ci)管(guan)(guan)(guan)空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)回转式预(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)工(gong)作原理(li)是(shi):预(yu)(yu)热(re)(re)器(qi)转子(zi)部件(jian)由数万(wan)计的(de)(de)(de)传(chuan)热(re)(re)元件(jian)组成,当空(kong)(kong)(kong)(kong)预(yu)(yu)器(qi)缓慢旋转,烟气(qi)(qi)和空(kong)(kong)(kong)(kong)气(qi)(qi)逆向交替流经空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)。蓄热(re)(re)元件(jian)在(zai)烟气(qi)(qi)侧吸(xi)热(re)(re),在(zai)空(kong)(kong)(kong)(kong)气(qi)(qi)侧放热(re)(re),从(cong)而达到降(jiang)低锅炉排烟温(wen)度(du),提高热(re)(re)风温(wen)度(du)的(de)(de)(de)预(yu)(yu)热(re)(re)作用(yong)。因此,须用(yong)框式水(shui)(shui)平(ping)(ping)(ping)仪调(diao)整搪(tang)瓷(ci)管(guan)(guan)(guan)空(kong)(kong)(kong)(kong)气(qi)(qi)预(yu)(yu)热(re)(re)器(qi)的(de)(de)(de)水(shui)(shui)平(ping)(ping)(ping)度(du),直(zhi)至符合(he)设(she)计要求。
  3.清(qing)洗(xi)搪瓷(ci)管空气预热设备一般用清(qing)洗(xi)剂或煤(mei)油。清(qing)洗(xi)后,要及时用帆布覆盖,严禁杂(za)物掉(diao)入轴承内部。
