电热管维护事项设备拆卸、维护和注意事项: 2.1空气电加热器在维护时,首先关掉总电源,并挂有检修标致牌,拆卸时先打开空气电加热器的防护罩,用万用表检查单支电热元件是否短路,如有需要拆卸时,应采用配备的专用扳手进行,拆卸应注意不要用力过猛而碰损其它加热元件。 2.2维护加热元件时,检查各加热元器件是否完好,如有接线端松动或接线铜排有活络现象,用扳手将螺栓上的螺母拧紧。 2.3拆卸空气加热器严禁用铁锤猛敲猛击,防止震坏加热元件或震松元器件上的螺母造成通电时接触不良,影响加热器的加热效果。拆卸的部件要放置安 全地方,以免损坏部件。 2.4拆卸热电阻时,切不可硬扳硬扭,以免造成热电阻损坏。 2.5热电阻维护:打开上面端盖,清除灰尘,检查连线端子是否完好,传感线缆是否有氧化或脱落现象,如有应即时更换。 2.6拆卸进出口法兰螺栓时,如有螺栓锈蚀,切不可用铁锤敲打,避免震坏电器元件,采用氧割拆卸,并注意周围是否有易燃物,确保安全操作。 2.7拆卸控制柜更换电器元件时,拧卸螺栓不可用力过猛,以免碰掉其它电源线或损坏其它电器,并认清各接线端子的标志,避免接错端子,造成电热元件损坏。Heating pipe maintenance matters equipment demolition, maintenance and precautions: 2.1 in the maintenance of the air heater, first turn off the main power and hung overhaul Peugeot brand, demolition when the first open air heater shield with a multimeter check whether the short single heating element, if necessary, removal should be used with a special wrench, demolition should be careful not to use too much force and collision damage other heating elements. 2.2 Maintenance heating element, check the heating components are in good condition, if the terminal is loose or copper wiring with active phenomenon, with wrench to tighten the nut on the bolt. 2.3 Remove the air heater is strictly prohibited hit with a hammer pounding, bad heating element to prevent shock or vibration caused by loose nuts on components when power is bad, affect heater heating effect. Removed parts to be placed a safe place to avoid damage to components. 2.4 Removing thermal resistance, must not pull hard twisting hard to avoid damage to the thermal resistance. 2.5 Thermal Resistance Maintenance: open the top cover, remove dust, check the connection terminal is intact, the sensing cable has oxidized or off phenomenon, if any should be replaced immediately. 2.6 Removing outlet flange bolts if bolts rust, must not be beat with a hammer, to avoid bad shock electrical components, the use of oxygen-cutting removal, and note whether there around combustibles, to ensure safe operation. 2.7 Removing the control cabinet replacement of electrical components, can not overexert breakout bolt, so knocked power lines or other damage other appliances, and recognize the signs of each terminal to avoid a wrong terminal, causing damage to the heating element.
