作為一(yī)款(kuǎn)常用的工業設備,角(jiǎo)管鍋爐並(bìng)非可以一直使用下去,它是有一定使用壽命的。不僅如此,角管鍋爐在運作過程中還可能會發生故障,從而(ér)對其運行效果造(zào)成一定的影響。漏水(shuǐ)就是角管鍋爐(lú)使用期間常見的故障之一,看(kàn)看維修人員(yuán)是如何解決此類問題的?
角管鍋爐漏水之後該怎麽辦
內壁是(shì)角管鍋爐漏水的常見部位,這其中還(hái)分為鍋筒漏水和水冷壁(bì)及下降(jiàng)管漏水,如果是前者漏眼比較小的話,可以進行鋼號(hào)相同挖補,挖(wā)補後再進(jìn)行探傷;而後前(qián)漏(lòu)水就需要換管,麵積較大的更換一根。
相(xiàng)對來說,如果是角(jiǎo)管鍋爐鍋筒內漏水的話,消(xiāo)耗的(de)修補費用還是比較高的,但主要還是取決於漏點所在的位(wèi)置以及漏點(diǎn)大小。若出現鍋爐滲出紅色鍋水,這說明是水(shuǐ)質出現問題,可能因為堿度低或者(zhě)水中溶(róng)解氧過高而(ér)造成的金屬腐(fǔ)蝕。堿度低可以向鍋水中投加(jiā)氫(qīng)氧化鈉或磷酸(suān)三鈉,水中溶解氧過高要通過除氧器來解決。
其次,角管鍋爐的水處理係統(tǒng)也會漏水,需先檢查一些是否是鍋爐腐蝕造成的,是的話是先除水垢,修理好漏水(shuǐ)部(bù)分,再對循環水進行處理,加入藥劑,對鍋爐(lú)等設備材質進行緩蝕,阻垢,保護。
另外,角管鍋爐煙道(dào)漏水也(yě)會引起不良後果(guǒ),解決的方法是先檢查是不是(shì)鍋爐(lú)爆管或是管板裂紋所致,如果需要換管、挖補看煙道所用(yòng)的材質,鋁和不鏽鋼材(cái)料可以用鋁(lǚ)絲或碳鋼氬焊,鐵材料可直接酸(suān)性焊條(tiáo)。
除此之外,角管鍋爐(lú)中還會(huì)漏水的就是它的閥(fá)門,這類問題比較好解決,隻(zhī)要(yào)加盤根或更換新的閥門就可以(yǐ)了。角管鍋爐中所有的漏水問題解決(jué)之後,還要內進行測試,確保萬無一失。
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 locations 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.
