如何对太阳能热水器进行保养除垢?

太阳能热水器应该定期进行系统排污,防止管路阻塞;并对水箱进行清洗,保证水质清洁。排污时,只要在保证进水正常的情况下,打开排污阀门,到排污阀流出清水就行了。定期清除太阳集容器透明盖板上的尘埃、污垢,保持盖板的清洁以保证较高的透光率。清洗工作应在清晨或傍晚日照不强、气温较低时进行,以防止透明盖板被冷水激碎。
Solar water heater system should be regularly discharged to prevent pipe blockage; and the water tank should be cleaned to ensure clean water quality. When blowdown, just open the blowdown valve under the condition that the water inflow is normal until the water flows out of the blowdown valve. Regularly remove the dust and dirt on the transparent cover plate of the solar collector, and keep the cover plate clean to ensure high light transmittance. The cleaning work should be carried out in the morning or evening when the sunshine is not strong and the temperature is low, so as to prevent the transparent cover plate from being broken by cold water.
一、注意检查透明盖板是否损坏,如有破损应及时更换。对于真空管太阳热水器,要经常检查真空管的真空度或内玻璃管是否破碎,当真空管的钡——钛吸气剂变黑,即表明真空度已下降,需更换集热管。
1、 Pay attention to check whether the transparent cover plate is damaged. If it is damaged, it should be replaced in time. For vacuum tube solar water heaters, it is necessary to check the vacuum degree of the vacuum tube or whether the inner glass tube is broken. When the Ba Ti getter in the vacuum tube turns black, it means that the vacuum degree has decreased and the collector tube needs to be replaced.
二、真空管太阳热水器除了清洗真空管外,还应同时清洗反射板。巡视检查各管道、阀门、浮球阀、电磁阀、连接胶管等有无渗漏现象,如有则应及时修复。集热器的吸热涂层若有损坏或脱落应及时修复。所有支架、管路等每年涂刷一次保护漆,以防锈蚀。

2、 Besides cleaning the vacuum tube, the reflector should be cleaned at the same time. Patrol inspection of the pipeline, valve, ball valve, solenoid valve, connecting hose and other leakage phenomenon, if any, should be repaired in time. If the heat absorbing coating of the collector is damaged or falls off, it should be repaired in time. All supports and pipelines shall be painted with protective paint once a year to prevent corrosion.

                                                     

三、防止闷晒。循环系统停止循环称为闷晒,闷晒将会造成集热器内部温度升高,损坏涂层,使箱体保温层变形、玻璃破裂等现象。造成闷晒的原因可能是循环管道堵塞;在自然循环系统中也可能是冷水供水不足,热水箱中水位低于上循环管所致;在强制循环系统中可能是由于循环泵停止工作所致。
3、 Prevent from drying. If the circulation system stops circulating, it is called airtight. Airtight will cause the internal temperature of the collector to rise, damage the coating, deform the insulation layer of the box and break the glass. The reason for the suffocation may be that the circulating pipe is blocked; in the natural circulation system, the cold water supply is insufficient, and the water level in the hot water tank is lower than that of the upper circulating pipe; in the forced circulation system, the circulating pump may stop working.
四、安装有辅助热源的全 天候热水系统,应定期检查辅助热源装置及换热器工作正常与否。对于辅助热源是电热管加热的,使用之前一定要确保漏电保护装置工作可靠,否则不能使用。对于热泵-太阳能供热系统,还应检查热泵压缩机和风机工作是否正常,无论哪部分出现问题都要及时排除故障。
4、 For all-weather hot water system with auxiliary heat source, the auxiliary heat source device and heat exchanger should be checked regularly. For the auxiliary heat source is heated by electric heating tube, make sure that the leakage protection device works reliably before use, otherwise it cannot be used. For the heat pump solar heating system, we should also check whether the heat pump compressor and fan work normally, no matter which part of the problem should be timely troubleshooting.
五、冬季气温低于0℃时,平板型系统,应排空集热器内的水;安装有防冻控制系统功能的强制循环系统,则只需启动防冻系统即可,不必排空系统内的水。
5、 When the temperature is lower than 0 ℃ in winter, the flat system should empty the water in the collector; if the forced circulation system is installed with the function of antifreeze control system, it is only necessary to start the antifreeze system instead of emptying the water in the system.
