作为一款常用的工业设备,角管锅炉并非可以一直使用下去,它是有一定使用寿命的。不仅如此,角管锅炉在运作过程中还可能会发生故障,从而对其运行效果造成一定的影响。漏水就是角管锅炉使用期间常见的故障之一,看看维修人员是如何解决此类问题的?
角管锅炉漏水之后该怎么办
内壁是角管锅炉漏水的常见部位,这其中还分为锅筒漏水和水冷壁及下降管漏水,如果是前者漏眼比较小的话,可以进行钢号相同挖补,挖补后再进行探伤;而后前漏水就需要换管,面积较大的更换一根。
相对来说,如果是角管锅炉锅筒内漏水的话,消耗的修补费用还是比较高的,但主要还是取决于漏点所在的位置以及漏点大小。若出现锅炉渗出红色锅水,这说明是水质出现问题,可能因为碱度低或者水中溶解氧过高而造成的金属腐蚀。碱度低可以向锅水中投加氢氧化钠或磷酸三钠,水中溶解氧过高要通过除氧器来解决。
其次,角管锅炉的水处理系统也会漏水,需先检查一些是否是锅炉腐蚀造成的,是的话是先除水垢,修理好漏水部分,再对循环水进行处理,加入药剂,对锅炉等设备材质进行缓蚀,阻垢,保护。
另外,角管锅炉烟道漏水也会引起不良后果,解决的方法是先检查是不是锅炉爆管或是管板裂纹所致,如果需要换管、挖补看烟道所用的材质,铝和不锈钢材料可以用铝丝或碳钢氩焊,铁材料可直接酸性焊条。
除此之外,角管锅炉中还会漏水的就是它的阀门,这类问题比较好解决,只要加盘根或更换新的阀门就可以了。角管锅炉中所有的漏水问题解决之后,还要内进行测试,确保万无一失。
As a commonly used industrial equipment, a corner tube boiler cannot always be used. It has a certain service life. Not only that, but corner tube boilers may also malfunction in the process of operation, which will have a certain impact on their operational effectiveness. Water leakage is one of the common faults during the use of angle boilers. See how maintenance personnel solve such problems.
What to do after the corner boiler leaks
The inner wall is a common part of the water leakage of the corner boiler, which is also divided into the water leakage of the boiler drum and the water pipe wall and down pipe, if the former is relatively small, it can be the same steel digging, digging and then testing; Leaks need to change the pipe, a larger area to replace one.
Relatively speaking, if it is a leak in the corner boiler boiler drum, the cost of repairs is still relatively high, but mainly depends on the location of the leak and the size of the leak. If a boiler seeps out of red pot water, this indicates a problem with the quality of the water. Metal corrosion may be caused by low alkalinity or high dissolved oxygen in the water. The low alkalinity can add sodium hydroxide or trisodium phosphate to the pot water. Dissolved oxygen in the water is too high to be solved by the deaerator.
Second, the angle of the tube boiler water treatment system will leak, you must first check whether some of the boiler corrosion caused by yes, then the first descaling, repair the leakage part, and then recycled water treatment, adding pharmaceuticals, the boiler and other equipment Material corrosion, scale, protection.
In addition, the corner pipe boiler flue leaking can also cause adverse consequences, the solution is to check whether the boiler squib or tube plate cracks caused by, if you need to change pipe, digging to see the flue used in the material, aluminum and stainless steel Can use aluminum or carbon steel argon welding, iron material can be directly acidic electrode.
In addition, the angle tube boiler will also leak its valve, this kind of problem is better solved, as long as the root or replace the new valve on it. After all the leaks in the angle tube boilers are resolved, they are tested internally to ensure that they are perfectly safe.
