There may be many reasons for the cracking of the quartz sleeve of the UV lamp in the UV sterilizer<\/a>, which are usually related to physical stress, temperature fluctuations, water quality conditions and other factors.<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Here are some common reasons and corresponding solutions<\/span>:
1. Excessive pressure<\/span>
Cause: The quartz sleeve may not be able to withstand the high water pressure in the system, especially when it exceeds its designed pressure range.<\/p>\n

Solution: Make sure the system pressure is within the tolerance range of the quartz sleeve. If necessary, you can install a pressure reducing valve to control the pressure. In addition, choose the sleeve material and thickness that meet the system pressure requirements.<\/p>\n

2. Sudden temperature change<\/span>
Cause: The quartz sleeve expands too fast when heated or contracts too fast when cooled, which will cause stress and cause cracks in the sleeve.<\/p>\n

Solution: Avoid cold water directly impacting the heated sleeve, keep the temperature in the system relatively stable, preheat the water body or install a temperature control system to reduce the situation of drastic temperature changes.<\/p>\n

3. Mineral deposition in water quality<\/span>
Cause: Minerals in water quality (such as calcium, magnesium, etc.) form scale on the quartz sleeve, which will cause uneven stress and cause the sleeve to crack under high temperature or high pressure.<\/p>\n

Solution: Clean the quartz sleeve regularly to ensure that there is no scale deposit on the surface; for hard water areas, it is recommended to install a water softener or descaling device to reduce the mineral content in the water.<\/p>\n

4. Improper installation or maintenance operation<\/span>
Cause: Careless collision or uneven external force during installation will cause invisible cracks in the quartz sleeve, and long-term use under high pressure or temperature difference will easily lead to cracks.<\/p>\n

Solution: Be careful during installation and maintenance, avoid external force impact, and use the correct installation tools and methods. In addition, check the sleeve regularly for fine cracks.

5. The thermal expansion coefficient of the lamp tube and the sleeve does not match<\/span>
Cause: When the thermal expansion coefficients of the materials of the UV lamp tube and the quartz sleeve do not match, asynchronous thermal expansion will occur during work, causing the sleeve to crack.<\/p>\n

Solution: Use a well-designed and tested sleeve and lamp combination to ensure that the compatibility of the materials meets the requirements of the working environment.<\/p>\n

6. Sleeve quality problem<\/span>
Cause: Defects in the quartz sleeve material or manufacturing process may cause cracks in the sleeve after a period of use.
Solution: Choose a reliable brand and qualified quartz sleeve, and check the product’s quality inspection report when purchasing to avoid using poor quality sleeves.<\/p>\n

Samenvatting
The key to avoiding quartz sleeve cracking is to control the water pressure and temperature changes in the system, clean and check the sleeve status regularly, and choose the right materials and products.<\/p>\n
