What are the installation methods and precautions for medium-pressure UV disinfectors?

　　 Medium-pressure UV sterilizer It must not be installed on or immediately behind the pump’s discharge pipe. This is to prevent water hammer damage to the timing sleeve and lamp tube when the pump stops working. If the timing sleeve becomes damaged, the UV sterilizer equipment will leak. So, what are the installation methods and precautions for medium-pressure UV disinfectors? Below, we’ll share this information with you—let’s take a look!

　　What are the installation methods and precautions for medium-pressure UV disinfectors?

　　1. Install the equipment according to the strict installation procedures, paying attention to the direction of water inflow and outflow as well as the equipment’s specified level.

　　2. When connecting the sterilizer to its pipeline, the valve should be securely fastened. The ultraviolet sterilizer cannot bear the weight of the pipeline or other accessories; however, the ultraviolet sterilizer itself becomes relatively heavy during operation.

　　3. When installing the disinfection unit, leave a spare space for future maintenance and inspection. Do not use materials at pipe joints that could compromise water quality and hygiene.

　　4. When installing the medium-pressure UV disinfection unit, leave sufficient space to allow for future lamp replacement.

　　5. When installing the sterilizer, ensure that the control panel faces outward for easy operation.

　　6. When installing the medium-pressure UV disinfection unit, the equipment should be bypassed. If the equipment needs to be repaired or replaced, the bypass should be closed, ensuring that the working water remains unaffected and allowing for easy equipment replacement.

　　A manufacturer of medium-pressure UV disinfectors shares: What are the hazards of prolonged exposure to ultraviolet light?

　　1. Photokeratitis: Ultraviolet wavelengths can cause keratitis and conjunctivitis. At first, I only felt a foreign-body sensation and mild discomfort in my eyes; in severe cases, I experienced burning sensations, intense pain, photophobia, tearing, and eyelid spasms. If the condition recurs, it can lead to chronic blepharitis and conjunctivitis. Excessive exposure to ultraviolet radiation can also cause damage to the retina.

　　2. Skin Erythema Reaction: Ultraviolet radiation can burn the skin, causing redness and pain after exposure. In severe cases, erythema may develop, even leading to blisters. Several days later, the erythema subsides, and the skin begins to peel and exhibit pigmentation.

　　3. Photosensitivity dermatitis: refers to skin lesions caused by exposure to certain chemicals, such as asphalt, followed by subsequent exposure to ultraviolet light.

　　4. Mutagenesis and Carcinogenesis: Ultraviolet radiation in mammals can induce genetic mutations, leading to skin cancer. Ultraviolet rays with wavelengths shorter than 320 nm are more likely to trigger skin cancer.

　　5. Ultraviolet radiation with wavelengths shorter than 250 nanometers, when acting on certain substances in the air, can also produce photochemical smog and toxic gases.

　　6. Ultraviolet lamps used for hospital disinfection emit ultraviolet light with wavelengths ranging from 180 to 290 nm, which have a germicidal effect. The wavelength range of these germicidal UV rays happens to be very close to the wavelength range of ultraviolet radiation that is harmful to humans, making them prone to causing damage to the eyes and skin.
