信息来源:网络摘录 浏览次数:504 发布时间:2018-01-30


    电伴热带因伴热保温效果明显,且节能、环保、安全,被广泛应用到了各行各业中。目前,已成为国内防冻保温、工艺维度维持的主要采用措施之一。这里列举电伴热带在装置过程中,需要留意的一些事项,以供用户参考。
电伴热带装置过程: 
    (1) 电伴热带可用于北方城市的工厂管道和运送管道的保温,装置时,应避开油气积累的暗角等。 
    (2) 电伴热带在装置时,应在管线体系悉数装置、调试完毕后进行。 
    (3) 电伴热带具有全天候防护能力。装置时应思考保护便利,整齐美观,且不使体系积累雨雪。 
    (4) 电伴热带的装置完工后,应逐路查看体系的绝缘电阻:各种电热带母线与屏蔽层之间、串联带芯线尾端末短接前的各芯线间绝缘电阻均应不小于20MΩ;然后再查看电热带直流电阻是不是正常,三相电阻是不是平衡。 
    这4个过程即是装置电伴热带必须遵守的过程,只要这么才干正常的装置好电伴热带,也能协助后续的保护。

电伴热带装置过程留意事项: 
    (1) 恒功率电伴热带装置时不允许穿插、叠绕,以防止过热,影响商品使用寿命。
    (2) 装置电伴热带接线盒时,并联带应留有必定殷实量,以便利维修。 
    (3) 装置电伴热带要思考管道阀门、设备等附件拆开便利,且不该损坏电热带。 
    (4) 装置并联电伴热带时,应留意二头“冷端”方位,确保带头发热段控制在需伴热的部位:并留意芯线、发热丝与屏蔽层相互之间不能触碰,避免短路。
