Using ultraviolet disinfection sterilization equipment need to pay attention to?

Uv sterilizer lampis a purely physical way of disinfection, it USES a special design of high efficiency, high strength and long life of ultraviolet lamp produced by strong ultraviolet light C water, when the water of bacteria, viruses, algae, such as by a certain dose of UVC light irradiation, the cell's DNA, RNA structure destruction and cell regeneration to, loss of bacteria and viruses replicate ability, so as to achieve the disinfection and purification of water. Ultraviolet lamp as the fang heart most parts, in the use process we should pay attention to what? Use ultraviolet disinfection sterilization equipment note 1, ultraviolet water sterilization equipment mechanical and electrical parameters, provide matching of driving power source is critical. Power transformer, capacitor or electronic circuits, when the choice must match the parameters of the UV lamp. 2, the service life of tubes is influenced by many factors, such as: the number of lamps, and working time after every lamps, electricity and heat operation data, as well as to the tubes if properly handled, etc. , will affect the life of the lamp; Often, therefore, the life of the average life expectancy of guaranteed by the manufacturer. 3 lamps, too frequently, can cause early to black on both ends of the tube, gradually affect the lamp body will turn black, finally lead to a drop tube power output. Avoid too often is the lamp of cold start, when a bulb light beginning, internal voltage is very low. On both ends of the electrodes in this period of time will emit tungsten, this will make many dot pollutants inside the tubes, as one of the reasons for the premature damage of the tubes, therefore, should be under the condition of high voltage lighting, lamps and shorten time. 4, microbial has its specific uv to kill, and die dose standards, its dose is the product of the radiation intensity and irradiation time, The sterilization dose = irradiation intensity & middot; Irradiation time/K = I· (t) That ultraviolet irradiation dose depends on the intensity of the ultraviolet (uv) size and the length of the irradiation time, high strength and low strength of short time long time exposure of its effect is the same. 5, uv quartz tube use after a period of time will gradually aging, ultraviolet radiation intensity will recession, in order to reach the effect of disinfection, quartz lamp irradiation intensity should be check regularly test, found that the intensity of ultraviolet germicidal lamp is not enough should be replaced immediately. 6, ultraviolet radiation to human body skin can produce a lot of damage, don't use konche germicidal lamps in some places, more don't use eyes lighted tubes, due to the short wave ultraviolet ray can't through the common glass, so the glasses can avoid injury to the eye. 7, in the places where staff activity, generally cannot use ozone tube, because ozone can promote human hemoglobin condensation, cause enough oxygen to the body, in the feeling of dizziness, nausea, affect the body health, especially in the ozone concentration & gt; 0. 3ppm ( mg/m2 ) , it will cause serious harm to human body.
