太陽能熱水工程排氣孔漏水原因分析
2023-09-13
在儲水箱的頂端安裝的是上排氣管，上排氣管一般由排氣帽、防塵圈和密封圈組成，在太陽能熱水工程安裝使用半年左右時(shí)間后，防塵圈會出現(xiàn)老化現(xiàn)象。這樣，當(dāng)儲水箱里面的水蒸氣從水箱中排出時(shí)，遇到外邊的冷空氣就會變成水珠，順排氣管下流通過防塵圈進(jìn)入水箱保溫層，同樣，在下雨天，雨水也會順著防塵圈進(jìn)入保溫層。當(dāng)保溫層內(nèi)的聚氨酯發(fā)泡材料吸水達(dá)到飽和時(shí)，就會在水箱下端的某個縫隙出現(xiàn)漏水現(xiàn)象。濟(jì)南太陽能配件給我們總結(jié)了一下，出現(xiàn)這種情況的一般原因有：
The upper exhaust pipe is installed at the top of the water storage tank. The upper exhaust pipe is generally composed of exhaust cap, dust ring and sealing ring. After the installation and use of solar hot water project for about half a year, the aging phenomenon of the dust ring will appear. In this way, when the water vapor in the water storage tank is discharged from the water tank, encountering the cold air outside will become water droplets, and flow down the exhaust pipe through the dust-proof ring into the water tank insulation layer. Similarly, in rainy days, rainwater will also follow the dust-proof ring into the insulation layer. When the water absorption of polyurethane foam material in the insulation layer reaches saturation, water leakage will occur in a gap at the bottom of the water tank. Jinan solar energy accessories give us a summary, the general reasons for this situation are:
1、因自來水水壓過大，上水過程中水會濺起，從而導(dǎo)致水箱內(nèi)的水還未滿就從排氣孔處流出。
1. Because of the excessive pressure of tap water, the water will splash in the process of feeding water, which results in the water in the tank flowing out from the vent before it is full.
解決方法：調(diào)整自來水壓標(biāo)準(zhǔn)水壓。
Solution: Adjust tap water pressure to standard water pressure.
2、回水管路過長或不暢通，導(dǎo)致水滿后水不能及時(shí)的從回水管路中流出，實(shí)際水箱的水已滿，繼續(xù)上水就會從其它排氣孔處流出。
2. The backwater pipeline is too long or unobstructed, which results in that the water can not flow out of the backwater pipeline in time after the water is full. The water in the actual tank is full, and the water will flow out from other exhaust holes when the water is continued.
解決方法：該問題屬自然規(guī)律，使用回水管無法排除該問題，安裝儀表可解決該問題。
Solution: This problem belongs to the natural law. The problem can not be eliminated by using the return water pipe. The problem can be solved by installing instruments.
3、上水閥門或電磁閥未關(guān)緊，導(dǎo)致始終慢上水，水滿后就會從排氣孔處流出。
3. The upper water valve or solenoid valve is not closed, which results in slow water feeding all the time. When the water is full, it will flow out from the exhaust hole.
解決方法：關(guān)緊上水閥門或?qū)收喜考M(jìn)行維修。
Solution: Close the water valve or repair the faulty parts.
4、水溫過高產(chǎn)生的水蒸氣，該情況屬正?，F(xiàn)象。
4. Water vapor produced by excessive water temperature is a normal phenomenon.
另外，儲水箱在冬季嚴(yán)寒時(shí)也會因保溫層內(nèi)的聚氨酯發(fā)泡材料浸水結(jié)冰而出現(xiàn)儲水箱脹箱、外側(cè)蓋脫落等現(xiàn)象。這種儲水箱漏水現(xiàn)象為隱秘，一般不易被人發(fā)現(xiàn)和重視。造成該現(xiàn)象的主要原因是上排氣管與儲水箱外殼密封處的防塵圈使用壽命太短。
In addition, the water storage tank in the winter cold will also be due to the polyurethane foam material in the insulation layer immersion and freezing and the expansion of the tank, the outer cover falling off and other phenomena. This kind of leakage of water storage tank is the most hidden phenomenon, and it is generally not easy to be found and paid attention to. The main reason for this phenomenon is that the service life of the dust-proof ring at the seal of the upper exhaust pipe and the shell of the water storage tank is too short.
