Description :

　　Swimming Pool Water UV Disinfection Device for Children's Swimming Pool Water UV Disinfection Medium pressure UV refers to a device that uses a mercury lamp as a light source and uses the 253.7nm ultraviolet radiation emitted by mercury vapor discharge inside the lamp tube as the main spectral line to disinfect drinking water (referred to as a disinfection device)

　　UV sterilizer refers to a device that uses a UV mercury lamp as a light source to disinfect drinking water by utilizing the 253.7nm ultraviolet radiation emitted by mercury vapor discharge inside the lamp tube as the main spectral line (referred to as a sterilizer).

　　UV sterilizers have the characteristics of no dead corners, good light irradiation conditions, low energy consumption, flexible and convenient equipment installation and disassembly, and no secondary pollution. Compared with chlorine gas sterilization, UV sterilizers do not require the addition of chemical agents, have no secondary pollution, and no mixing equipment, greatly reducing equipment operating costs. If it is drinking water, UV sterilizers are safe and will not have adverse effects on the human body due to excessive agents. Compared to ozone sterilizers, ultraviolet sterilizers have the advantages of low energy consumption, no large mixers, and no fishy smell. They not only have a good sensory experience, but also reduce operating costs.

　　The structural form of UV sterilizers: UV sterilizers are divided into closed and open types according to the different water flow boundaries.

　　Characteristics of medium voltage ultraviolet sterilizer:

　　Medium voltage ultraviolet lamp: Adopting high-quality American imported Lightsources brand ultraviolet lamp with high power, reducing the number of lamp configurations. Swimming pool water pressure ultraviolet sterilizer for children's swimming pool water pressure ultraviolet disinfection. Medium voltage ultraviolet can treat high flow water bodies. Compared with low-voltage ultraviolet lamps, ultraviolet light has a higher intensity and a wider wavelength of radiation.

　　Temperature probe: It immediately detects the temperature of the water. The swimming pool water pressure ultraviolet disinfection device for children's swimming pool water pressure ultraviolet disinfection ensures that the equipment operates at a working temperature of 0-45 degrees Celsius.

　　UV intensity probe: The intensity monitor used in the medium voltage UV sterilizer only responds to specific UV wavelengths that have sterilization effects. It can be connected to computers and PLCs, saving power consumption for the operation of the system.

　　Quartz sleeve: In order to better protect the ultraviolet lamp tube, there is a quartz sleeve outside each ultraviolet lamp tube. Therefore, the quality of quartz tubing largely determines the sterilization effect of medium voltage ultraviolet sterilizers, and high-quality quartz tubing can ensure that the penetration rate of ultraviolet rays reaches over 90%.

　　Daily cleaning: Due to water quality and exposure to ultraviolet light, the surface of the quartz sleeve will crystallize after a period of use. The thickness of the crystals will reach a certain level, which will affect the penetration ratio of ultraviolet light. Therefore, the quartz sleeve needs to be cleaned regularly. The medium pressure ultraviolet sterilizer is equipped with an automatic cleaning system, which can automatically clean the quartz sleeve according to the reading of the ultraviolet intensity detector in the swimming pool water. During the cleaning process, the system operates normally without the need for water supply or manual intervention, greatly reducing the workload of on-site personnel.
