一台二手海德堡四开四色胶印机，有一次在运行中时有出现自动给纸装置吸气不足、递纸器吸纸不稳的故障。由于当时生产任务很急，所以没有及时卸下检查维修，为此又运行了一段时间后最终出现了分气阀失灵，吸咀无法吸气的故障了。于是，现场抢修先将分气阀卸下检查，在折卸出阀体后发现该阀体（阀体直径42mm，铸铜材料）有约30mm长的一段外圆面严重研磨“烧”损，被磨损的面存在沟痕。这种状况要么更换阀体，要么修复受损面而使阀体能与阀套正常配合。 因为没有备件，所以，我决定先采用补焊修复处理。如果以铜钎焊补，工件在加热钎焊过程中会产生变形的可能，若以锡焊补则不会变形，操作简便，只是硬度不能与铜同等。但作为现场的应急处理则是可以采用的，为此，我先选择用焊锡补，锡焊以松香作焊剂（比用焊锡膏效果好），用150w的电烙铁加热，达到极限温度后才能开始进行焊，焊上锡层后要高出原来的外圆尺寸，之后将这补焊后的阀体夹在车床上精车和砂光焊层，使之达到正常的尺寸。对阀套的处理只是将阀套夹在车床上，用0#砂布将研磨受损的部位砂光就行了。这样在短时间内即完成了修复处理，重新装上机运行使用，性能正常，达到使用要求。说明采用这种方法处理是可行的。 除了上述那样处理可行外，还有象上述那样的磨损处理有条件的也可以用粘涂技术进行修复。粘涂技术处理具有操作方便，适用性广，涂层与母体结合性好，修复速度快、质量好、成本低等优点。粘涂所采用的粘涂剂有耐磨剂、填补剂、紧急修补剂等，粘涂剂一般类似泥状，分为A·B两个组分，使用时把A、B两组按说明的比例混合搅和均匀后涂敷（涂敷之前对涂敷面要用丙酮清净），在固化后车削，恢复到原来的尺寸。这种粘涂剂固化后的硬度与铜的硬度相差无几，进口的粘涂剂如美国的贝尔佐纳系列，国产的有TS111牌号，这些质量比较好。可供同行选择。

Used to open a four-four-color offset press Heidelberg, once in operation occurs automatically when suction device to the paper shortage, paper delivery paper Absorbed instability failure. At that time production tasks hurry, so there is no time unloading inspection, maintenance, and to this end some time after running the final emergence of sub-valve failure can not inhale smoke Tsui broken down. Thus, on-site repairs to remove the first sub-valve check valve in the fold after unloading showed that the body (body diameter of 42mm, bronze material) about 30mm long cylindrical grinding face serious, "burnt" loss, There are grooves worn surface. This situation either valve replacement or repair damaged body surface with the valve cover Ershi normal with. Because there is no spare, so I decided to deal with repair welding repair. If copper brazing up the workpiece in the heating during soldering may cause deformation, if soldering is not up distortion, simple operation, but the hardness can not be the same with copper. But as the scene of the emergency is can be used, and this, I first chose to solder fill, solder flux rosin for (effective than paste), with a 150w electric iron heating temperature before beginning the limit for welding, welding on the tin layer to be higher after the original cylindrical size, this repair welding after the body after intensive vehicles caught in the lathe and sanding welding layer, to reach a normal size. Treatment of the valve cover valve cover just caught in the truck bed, with 0 # emery cloth to the damaged parts ground sanding on the line. This is accomplished in a short time fix, and re installed on the machine running to use, performance of normal, reaching requirements. Help using this approach is feasible. In addition to the above address as possible, there is less wear and tear as the processing conditions can also be used to repair adhesive coating technology. Cohering technology processing is easy to operate, wide applicability, combined with the coating and matrix is good, repair speed, good quality and low cost. Sticky coating of paint used in a lubricant, fill the agent, emergency repair agent, is stuck paint generally similar to the Muddy, divided into A · B 2 component, use the A, B groups according to instructions proportion of mixed blend evenly coated (coating before the coating surface to use pure acetone), turning after curing, to restore to its original size. This sticky paint cured hardness and the hardness of copper is almost the same, the import of sticky paint, such as the United States, Belzona series, made in China have TS111 grade, the quality is better.
