The position and precautions of ultraviolet sterilizer in secondary water supply

The position of the over-flow ultraviolet sterilizer in the secondary water supply is required. It is not very important when the secondary water supply building is multi-storey, but when the building is high-rise, it is necessary to pay attention to the position of the ultraviolet sterilizer. Before this, let me explain the structure of the over-flow ultraviolet sterilizer: the ultraviolet sterilizer is made of 304 stainless steel into a closed reaction chamber, and passes through the quartz tube and the ultraviolet germicidal lamp from both ends. The ultraviolet germicidal lamp should avoid moisture and water immersion, so the quartz The tube plus the sealing component isolates the ultraviolet germicidal lamp from water. The quartz tube can resist strong pressure under uniform pressure, but the quartz tube is fragile and easily broken when the pressure is uneven. The water hammer effect is a vivid expression. It refers to a serious water hammer caused by the water flow hitting the pipeline when the feed water pump starts and stops.

The instantaneous pressure generated by water hammer can reach dozens or even hundreds of times of the normal working pressure in the pipeline. This large pressure fluctuation can cause strong vibration and noise in the pipeline system, and may damage the valve joint, which has a great destructive effect on the pipeline system. Therefore, when the water pump suddenly loses power, the water hammer will break the lamp tube and quartz tube of the ultraviolet sterilizer. When installing, it must be installed according to the requirements. Generally, the ultraviolet sterilizer is installed between the outlet of the water tank and the frequency conversion water pump, and must not be installed. At the outlet of the water pump, after the water hammer is generated, it is buffered by the pipeline, valves and the blades of the water pump to minimize the destructive force of the water hammer, and it can also reduce the damage of the high pressure of the pipe network to the ultraviolet sterilizer. Therefore, the ultraviolet sterilizer should be installed at the water inlet of the pump.

When the ultraviolet sterilizer is installed, in order to facilitate future maintenance, it is necessary to leave at least a length longer than the lamp tube at both ends (any one) of the ultraviolet sterilizer, so as to facilitate the replacement of the lamp tube and the cleaning of the quartz tube. When installing the ultraviolet sterilizer, it is recommended to install it last after other equipment has been debugged, because other equipment may have water seepage or water leakage during commissioning to prevent the ultraviolet sterilizer from entering water and short circuiting.
