How to replace the lamp tube of groundwater ultraviolet sterilizer
Replacement of the lamp tube of the ultraviolet sterilizer:
The imported lamp tube should be replaced after 9000 hours of continuous use or one year to ensure a high bacterial rate. When replacing the lamp, first unplug the power socket of the lamp, unplug the lamp, then insert the cleaned new lamp into the bacteria device, install the sealing ring, check for water leakage, and then plug in the power source. Be careful not to touch the timed glass of the new lamp with your fingers, otherwise the bacteria will be affected by the stains.
Regular cleaning of the ultraviolet sterilizer:
According to the water quality, the ultraviolet lamp and the timely glass tube should be cleaned regularly, and the test tube should be wiped with an alcohol cotton ball or gauze to remove the dirt on the timely glass tube and wipe it clean , So as not to affect the UV transmittance and sterilization effect.
The installation of the ultraviolet sterilizer generally follows the principle of left-in and right-out. The flanges of the water inlet and outlet can be connected, and the power button can operate normally. Ultraviolet sterilizer refers to a device that uses an ultraviolet mercury lamp as a light source and uses 253.7nm ultraviolet rays emitted by mercury vapor discharge in the lamp as the main spectrum to disinfect daily drinking water (disinfector for short)
Factors Affecting the Effect of Ultraviolet Sterilizer
The factors that affect the sterilization effect of ultraviolet rays are the intensity of ultraviolet rays, the wavelength of the ultraviolet spectrum and the irradiation time. The items to be noted when using the UV sterilizer are: Device orientation: The location of the UV device is as close as possible to the point of use, but there should also be operating space for inserting or pulling out the quartz tube sleeve from one end and replacing the lamp tube.
Flow rate:
In the same sterilizer, when the ultraviolet radiation energy is constant and the bacterial content in the water does not change much, the water flow rate through the sterilizer has a significant impact on the sterilization effect. The physical and chemical properties of water: water's chromaticity, turbidity, and total iron content all absorb ultraviolet light to varying degrees, and the result is that the sterilization effect is reduced.
Lamp power:
The ignition power of the lamp has a great influence on the sterilization power. The temperature of the medium around the lamp tube: the spectral energy of the ultraviolet lamp tube radiation is related to the temperature of the lamp tube wall. Quartz sleeves, the quality and wall thickness of the custom sleeves are related to the transmittance of ultraviolet rays, the purity of the quartz sleeves is high, and the power is good. Water layer thickness: The thickness of the water layer has a great relationship with the sterilization effect.
