厂家分析冷凝器、蒸发器更换铜管的步骤及注意事项

冷凝器、蒸发器更换铜管这个维修现在已经开始普遍起来了,这里说的蒸发器主要是满液式的蒸发器铜管,一方面是因为机组使用的水质问题,另一方面是由于意外故障,导致机组换热器出现铜管破裂进水故障。出现这个故障了,捷邦公司认业最经济最快的办法就是更换损坏的铜管,然后打压检漏,密封性良好后连接好管路准备调试,当然系统的除湿除水是必不可少少的一部,而且是至关重要的。这里主要探讨下冷凝器、蒸发器铜管更换的主要事项。

The maintenance of replacing copper pipes with condensers and evaporators has become common now. The evaporators mentioned here are mainly full-liquid evaporator copper pipes. On the one hand, the water quality problem of the unit is caused, on the other hand, by accidental faults, the copper pipes of the heat exchanger of the unit rupture and water intake fault. The most economical and fastest way for Jebbon Company to deal with this problem is to replace the damaged copper pipe, then press and check the leak. After good sealing, the pipeline is connected and ready for commissioning. Of course, the dehumidification and dewatering of the system is an indispensable part, and it is very important. This paper mainly discusses the main items of replacing copper tubes in lower condenser and evaporator. 

冷凝器更换铜管的步骤及注意事项:

Steps and precautions for replacing copper tubes in condensers:

1、测量好所要更换的铜管的规格尺寸,就是需要铜管的内径,壁厚,甚至材质等都需要有具体的数据和详细情况,否则拔管器会不合适。

1. Measuring the specifications and sizes of the copper tubes to be replaced requires specific data and details of the inner diameter, wall thickness and even material of the copper tubes, otherwise the extubator will be inappropriate.

2、和拔管器厂家沟通好情况,一再确认所需规格尺寸。

2. Communicate well with the extubator manufacturer and confirm the required specifications and sizes again and again.

3、初步推断、判断、预计铜管破裂位置,以便确定拔管的主攻方向。大面积冻裂的冷凝器和蒸发器一定是有规律的,这个已经在实际工作和维修中得到了多次的验证,不需要怀疑。建议需要做的就是先进行尝试拔出一根位于破损铜管密集处,便于确定破损位置,选择铜管出关端面。

3. Preliminary inference, judgment and prediction of the location of copper pipe rupture in order to determine the main direction of extubation. The condenser and evaporator of large area freezing cracking must be regular, which has been verified many times in practical work and maintenance, and need not be doubted. Suggestions need to do is first try to pull out a broken copper tube in the dense, easy to determine the location of the damage, choose the end of the copper tube out of the shutdown.

4、最好用液压拔管器进行施工。更换少数的话差别不大,如果更换十根以上,差别就太大了,如果是上百根那就完全不是一回事了。

4. It is better to use hydraulic pipe puller for construction. If you change a few, the difference is not big. If you change more than ten roots, the difference is too big. If you change hundreds of roots, it is not the same thing at all.

5、清洗冷凝器、蒸发器的壳程。当拔掉必要的更换的管后,清洗工作就变成第一工作了。此时由于进水导致的蒸发器、冷凝器壳程生锈和污泥比较多,选择高压水或者其他易挥发的溶剂进行清洗,并尽量清除掉不必要的其他物质混杂,增加维修难度。

5. Clean the shell side of condenser and evaporator. When necessary replacements are removed, cleaning becomes the first job. At this time, there are more rust and sludge in the shell of evaporator and condenser caused by water inflow. High-pressure water or other volatile solvents are selected to clean, and unnecessary mixtures of other substances are removed as far as possible to increase the difficulty of maintenance.

6、隔板的保护和预留支撑问题。

6. Protection of partition and reserved support.

如果当拔管的时候忽然听到一声咯吱很大的响动,由于没有在意,不知道是哪儿发出的声音,就不当一回事。但后来慢慢拔着就看出问题了,隔板似乎被铜管的破裂位和另一端的胀口给拉变形和移动了。以至于后来留好了支撑,但是最后穿管还是很费劲,偏差很大,有几根最后是强行凿进去的,可想而知是什么情况,不能不引起重视。 (这一条是极容易被忽略的,尤其更换铜管较多的地方场合)

If you suddenly hear a squeaky noise when you pull out the tube, because you don't care and don't know where the sound is, it's not a big deal. But then slowly pulling out the problem, the partition seems to be pulled and deformed by the rupture of the copper tube and the expansion at the other end. So that later retained the support, but the final pipe is still very laborious, deviation is very large, there are several finally forced into, can be imagined what the situation, can not but cause attention. (This one is easily overlooked, especially in places where copper tubes are replaced more often)

7、胀管的工艺要求至关重要,关系到保修,机组运行,机组的密闭性等重要问题。

7. The process requirement of expanding pipe is very important, which is related to the important issues such as maintenance, unit operation and unit closure.
