电伴热系统异常排除
时间 : 2022-02-06 13:20 浏览量 : 15

明确为何您的电加热器系统软件不可以考虑您的全过程加温要求。电伴热系统软件通常用于防寒,以保持管道和储水罐内的水、化学产品或液体的温度。假设仅靠保温不能合理地控制管道或储存罐的热损伤,电伴热能减少损失,使整体目标发热量释放,维持所需的加工过程温度。电伴热系统软件由伴热电缆、接线端子、温度传感机械设备及自动控制系统(温控、检测和配电设备)组成。

电伴热系统异常排除

尽管本系统软件的设计方(fang)案(an)和制(zhi)作工作非常稳定,但随着严寒和气温(wen)(wen)的升高(gao),极(ji)有(you)可能出现(xian)隔离开关跳闸、电源线路(lu)温(wen)(wen)度过(guo)低或(huo)过(guo)高(gao)等情(qing)况。本文将帮助你解决与(yu)电伴(ban)热系统有(you)关的典型(xing)难(nan)(nan)题(ti),找出直接原因,采取适(shi)当的纠正措(cuo)施(shi)。这篇文章并不(bu)容易让(rang)你解决所有(you)的难(nan)(nan)题(ti),但是在寒冷的季节,它应该(gai)能为你节省一些时(shi)间和不(bu)便(bian)。

隔离开关跳(tiao)电。

电(dian)伴热系统软件最普遍(bian)的难题是隔离开关跳(tiao)(tiao)电(dian)。这(zhei)类常见故障以二(er)种方法产(chan)生:电(dian)源电(dian)路通(tong)电(dian)后马(ma)上跳(tiao)(tiao)电(dian),或是几(ji)秒后跳(tiao)(tiao)电(dian)。观查行程安排時间很重要,由(you)于该提醒有(you)利于告之常见故障清除全过程。

电(dian)(dian)(dian)(dian)(dian)源(yuan)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)在通电(dian)(dian)(dian)(dian)(dian)时跳(tiao)电(dian)(dian)(dian)(dian)(dian)。插电(dian)(dian)(dian)(dian)(dian)期内电(dian)(dian)(dian)(dian)(dian)源(yuan)电(dian)(dian)(dian)(dian)(dian)路(lu)(lu)跳(tiao)电(dian)(dian)(dian)(dian)(dian)一般 是由(you)系统软件中某点对地(di)短路(lu)(lu)故障造成的。难题可能是电(dian)(dian)(dian)(dian)(dian)缆线自身、开关电(dian)(dian)(dian)(dian)(dian)源(yuan)联接(jie)或电(dian)(dian)(dian)(dian)(dian)源(yuan)插头。

一切常见故(gu)障清除都(dou)应包含兆欧(ou)表查(cha)验(图2),它能够测(ce)试电(dian)(dian)(dian)(dian)缆(lan)(lan)和电(dian)(dian)(dian)(dian)源(yuan)插头(tou)(tou)的(de)(de)接(jie)地电(dian)(dian)(dian)(dian)阻,以防(fang)护(hu)接(jie)地装(zhuang)置(zhi)的(de)(de)潜在性常见故(gu)障。兆欧(ou)表在金属材(cai)料纺织物或(huo)电(dian)(dian)(dian)(dian)线(xian)(xian)接(jie)头(tou)(tou)和电(dian)(dian)(dian)(dian)缆(lan)(lan)线(xian)(xian)的(de)(de)导(dao)电(dian)(dian)(dian)(dian)性芯中(zhong)间释(shi)放(fang)工作(zuo)电(dian)(dian)(dian)(dian)压(1000-2500伏直流电(dian)(dian)(dian)(dian)源(yuan),在于(yu)电(dian)(dian)(dian)(dian)缆(lan)(lan)线(xian)(xian)的(de)(de)种类)。第一步是将加(jia)热电(dian)(dian)(dian)(dian)缆(lan)(lan)与电(dian)(dian)(dian)(dian)缆(lan)(lan)线(xian)(xian)开关(guan)电(dian)(dian)(dian)(dian)源(yuan)接(jie)线(xian)(xian)端子中(zhong)的(de)(de)电(dian)(dian)(dian)(dian)源(yuan)插头(tou)(tou)防(fang)护(hu),并检测(ce)编织线(xian)(xian)和系统总线(xian)(xian)中(zhong)间的(de)(de)加(jia)热电(dian)(dian)(dian)(dian)缆(lan)(lan)。查(cha)验应有(you)利于(yu)保证 接(jie)地电(dian)(dian)(dian)(dian)阻做到或(huo)超出生产商提议的(de)(de)极(ji)小值。

假如接地电阻(zu)不符或超出(chu)生(sheng)产商(shang)提议的极小值(zhi),请实(shi)行(xing)下列流程。

第一(yi)步。确(que)(que)保(bao)(bao)电缆线(xian)导电芯板不(bu)与金(jin)属(shu)材料接(jie)(jie)地(di)装(zhuang)置编(bian)织线(xian)或(huo)其他金(jin)属(shu)材料接(jie)(jie)线(xian)端(duan)子接(jie)(jie)触。检查所(suo)有开关(guan)电源连接(jie)(jie)、射频连接(jie)(jie)器、三通(tong)盒(he)和(he)顶(ding)端(duan)的(de)(de)(de)紧密性,以确(que)(que)保(bao)(bao)对(dui)导电芯板和(he)所(suo)有金(jin)属(shu)材料组件(包括接(jie)(jie)地(di)装(zhuang)置织物)的(de)(de)(de)保(bao)(bao)护。假(jia)设(she)导电芯触到金(jin)属(shu)材料,进行必要的(de)(de)(de)维修和(he)兆欧表(biao)(biao)检查,直(zhi)到接(jie)(jie)地(di)电阻超过(guo)制造(zao)商(shang)的(de)(de)(de)最(zui)低(di)要求。检查端(duan)子和(he)顶(ding)部密封时,要确(que)(que)保(bao)(bao)所(suo)有连接(jie)(jie)都(dou)是干性的(de)(de)(de),因为湿冷的(de)(de)(de)端(duan)子或(huo)顶(ding)部密封会(hui)导致兆欧表(biao)(biao)检测(ce)失败。

第(di)二步(bu):要是(shi)没(mei)有(you)发(fa)觉金(jin)属(shu)材料零件或(huo)纺织物(wu)与导(dao)电(dian)(dian)性芯触碰,接地电(dian)(dian)阻依然过低,请防(fang)护(hu)电(dian)(dian)源(yuan)电(dian)(dian)路上的(de)每根加(jia)热(re)电(dian)(dian)缆(lan),各(ge)自开展兆欧表查验(yan)。这(zhei)能(neng)够协助(zhu)鉴别加(jia)热(re)电(dian)(dian)缆(lan)的(de)物(wu)理学毁坏地区,这(zhei)造成导(dao)电(dian)(dian)性芯和(he)管路上的(de)金(jin)属(shu)材料接地装置纺织物(wu)中间短路故障。查验(yan)管路系统软件,并在低检测的(de)零件上找(zhao)寻显(xian)著的(de)毁坏征(zheng)兆。要是(shi)没(mei)有(you)显(xian)著的(de)毁坏征(zheng)兆,最好(hao)是(shi)拆(chai)下来并拆(chai)换检测工作电(dian)(dian)压较低的(de)电(dian)(dian)缆(lan)线(xian)。较长的(de)一部分能(neng)够按(an)段检测,以(yi)防(fang)护(hu)常见(jian)故障。防(fang)护(hu)常见(jian)故障后(hou),请清除(chu)电(dian)(dian)缆(lan)线(xian)有(you)什么问题的(de)一部分,并且用新电(dian)(dian)缆(lan)线(xian)拆(chai)换。

第(di)三(san)步:假如(ru)(ru)加热电(dian)(dian)缆检测一切正常,再用兆欧表查(cha)验从(cong)电(dian)(dian)缆线接线端(duan)子到电(dian)(dian)伴热控(kong)制(zhi)面(mian)板的(de)电(dian)(dian)源插头。假如(ru)(ru)电(dian)(dian)源插头短路故障,请(qing)卸掉电(dian)(dian)源插头,换掉新的(de)。

电源电路(lu)溫度过低(di)。

电源电路溫(wen)度很有可能过低,由(you)于:

控(kong)温器或全过程控(kong)制(zhi)板的设(she)定有(you)误。

控温(wen)器(qi)布(bu)线不(bu)正确。

电缆(lan)线(xian)沒有(you)联接到开关电源。

电缆线联(lian)接到不正(zheng)确(que)的工(gong)作电压(ya)。

温度感应器置放不善(shan)。

温度感应器(qi)布线不正确。

电缆线(xian)总(zong)数不能(neng)相抵系统软(ruan)件中(zhong)的(de)热管散热器(qi)。

请采(cai)用下列流程明(ming)确超低(di)温的直接原(yuan)因。

第一步、保证 控(kong)温器(qi)或全(quan)过程自动(dong)控(kong)制系统设定为所需(xu)的管路溫度(du)。

第(di)二步、当(dang)做到预设(she)值(zhi)时,查验(yan)水(shui)温(wen)传感器的布线是不是关(guan)掉。大部分控(kong)温(wen)器能(neng)够从(cong)一(yi)个公共(gong)性接(jie)线端子联接(jie)到开与关(guan)或常闭(bi)部位(wei)。查验(yan)用(yong)以控(kong)温(wen)维护运用(yong)的控(kong)温(wen)器是不是从(cong)公共(gong)性接(jie)线端子联接(jie)到常闭(bi)部位(wei)。

第三步、查验电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)是不(bu)是再度(du)联(lian)接(jie)到开(kai)关(guan)电(dian)(dian)(dian)(dian)源(yuan)。测(ce)试电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)开(kai)关(guan)电(dian)(dian)(dian)(dian)源(yuan)接(jie)线(xian)(xian)(xian)端(duan)(duan)子(zi)和电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)端(duan)(duan)密封(feng)性中的(de)开(kai)关(guan)电(dian)(dian)(dian)(dian)源(yuan)。电(dian)(dian)(dian)(dian)源(yuan)电(dian)(dian)(dian)(dian)路尾端(duan)(duan)的(de)检测(ce)将保证 加(jia)热(re)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)在全部电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)长短上面有两根优(you)良的(de)系统总线(xian)(xian)(xian)。每一个电(dian)(dian)(dian)(dian)源(yuan)电(dian)(dian)(dian)(dian)路开(kai)始(shi)与结束(shu)时的(de)工作(zuo)电(dian)(dian)(dian)(dian)压读值应当(dang)相对(dui)性类似。远距离电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)会出现一些损耗;坠落量因(yin)电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)种类和生产商而(er)异,因(yin)而(er)请查询机器设备文本文档。可是,假如检测(ce)表明电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)逐渐于(yu)120伏(fu),完毕于(yu)0V,则(ze)最少有一根电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)系统总线(xian)(xian)(xian)输电(dian)(dian)(dian)(dian)线(xian)(xian)(xian)毁坏,因(yin)而(er)必(bi)须拆卸并拆换电(dian)(dian)(dian)(dian)缆(lan)(lan)(lan)(lan)线(xian)(xian)(xian)。

第四步、保证 电(dian)(dian)(dian)缆(lan)线联接(jie)到恰当的(de)工作电(dian)(dian)(dian)压(ya)。查验工作电(dian)(dian)(dian)压(ya)时,将(jiang)精确测量值与设(she)计方案文档开(kai)展较为(wei)。比如,由120伏工作电(dian)(dian)(dian)压(ya)供电(dian)(dian)(dian)系统(tong)的(de)240伏电(dian)(dian)(dian)缆(lan)线将(jiang)不可以(yi)维持恰当的(de)管路溫(wen)度(du)。开(kai)展必需(xu)的(de)调节以(yi)改(gai)正一切工作电(dian)(dian)(dian)压(ya)难题。
