蒸发器出现漏孔的修补方式:
The repair mode of the leak in the evaporator:
1、针对蒸发器铜管式蒸发器,泄漏通常都出现在焊接的地方,找到漏孔以后,应及时补漏。
1, for evaporator copper tube evaporator, leakage usually occurs in the place of welding. After finding the leakage hole, we should make up for leakage in time.
2、针对展示柜蒸发器不用拆卸就可以补漏的蒸发器,补焊前,要先剪开展示柜蒸发器压缩机上的封口,并对展示柜蒸发器稍微加热,使展示柜蒸发器内制冷剂产生的蒸汽从封口处排出。补焊时,要用银枪焊,而且通常都是用小号焊枪及焊嘴,同时火焰不能太强,并尽可能地缩短补焊时间,且动作迅速准确补漏,防止加热时间过长导致展示柜蒸发器大面积变形。
2, for the evaporator that can be leaks without dismantling the evaporator of the display cabinet, before the repair welding, the seal on the compressor of the evaporator of the display cabinet should be cut first, and the evaporator of the display cabinet is slightly heated so that the steam produced by the refrigerant in the evaporator of the display cabinet is discharged from the seal. When repairing welding, it is necessary to use silver gun welding, and usually use small welding gun and welding nozzle. At the same time, the flame can not be too strong, and as far as possible to shorten the repair welding time, and the action quickly and accurately leakage, prevent the heating time too long to cause large area distortion of the display cabinet evaporator.
3、针对铝板式的蒸发器出现的漏孔,补焊时,要先将蒸发器漏孔的四周清理干净,再按照以下方法修补:
3, in view of the leakage of the aluminum plate evaporator, we must first clean up the leakage of the evaporator before welding, and repair according to the following methods:
①将铝与锡熔化铸成2毫米粗的铝锡焊条,再用三百瓦的电烙铁将铝焊锡条熔化,同时在漏孔处,加热与摩擦同时进行。
(1) aluminum and tin were melted into 2 mm thick aluminum tin electrode, and then three hundred watts of electric soldering iron was used to melt the aluminum solder bar. At the same time, the heat and friction were carried out at the same time in the hole.
②清除废弃的电路板铜层,再将剩下的环氧树脂板磨成粉末,并过筛后与松香粉混合制成焊剂。在漏孔的四周放少许焊剂,再在有漏孔的地方摩擦电烙铁与焊条,就可以焊牢漏孔。
Second, remove the copper layer of the discarded circuit board, then the remaining epoxy resin plate is ground into powder, and after screening, the flux is mixed with the rosin powder. A little flux is placed around the leak, and then the electric iron and the electrode are rubbed in the place where there is a leak.
③将自凝粉与自凝水按10:6调和,等几分钟后,将少许调和液抹在漏孔的地方即可。
(3) reconcile the self coagulating powder with the self condensing water according to 10:6. After a few minutes, put a little mixture of liquid into the hole.
④先取百分之一稀磷酸溶液将漏孔四周处理干净,片刻之后涂层三氯化铁,1分钟以后,用一百瓦电烙铁进行补焊,焊补好后将残留的助焊剂处理干净。
(4) the one percent dilute phosphoric acid solution was taken to treat the leak around the hole, and then the iron trichloride was coated after a few minutes. After 1 minutes, the welding was made up with one hundred watts of electric soldering iron, and the residual flux was treated clean after the welding was repaired.
