Analysis of the factors that need to be considered when installing the ultraviolet sterilizer
The uv sterilizer has the characteristics of uniform water flow, no dead corners, good light conditions, thorough sterilization, low energy consumption, flexible and convenient installation, etc. The main material is stainless steel, and there is no metal ion infestation problem. The product structure is a closed container quartz sleeve type. Built-in electrical control device. Among them, the key ultraviolet lamp management theory has a life of up to 10,000 hours, reaching the international advanced level. The product is beautiful in appearance, compact in structure, convenient in operation and maintenance, and is widely used in industrial and mining enterprises, residents' lives, hotels, hotels, institutions and schools; Beverages or other industries with residual chlorine are not allowed in the water.
1: Ambient temperature
The on-site environment and temperature have a certain effect on the intensity of ultraviolet radiation. Too high or too low temperature will reduce the radiation intensity. Therefore, the on-site environment must be kept dry and ventilated. Generally, room temperature 20-40 ℃ is the suitable temperature for ultraviolet disinfection.
2: On-site power supply
The on-site power supply must use a separate line, and the same line cannot be used together with the variable frequency water pump, and the voltage must be stable. (Voltage 220±22V, frequency 50Hz±2.5 Hz) Unstable voltage will cause the lamp to flicker and burn out.
3: Installation location
The UV sterilizer should be installed horizontally (vertical installation is strictly prohibited). The equipment must be installed between the water pump and the water tank during on-site installation, and installed at the back of the water pump. When the pump is started, too much impact will damage the casing and cause the equipment to leak. Install the equipment on the main pipeline. No matter one or more UV sterilizers are used in parallel, a bypass pipeline and a shut-off valve should be installed to facilitate maintenance.
4: Installation base
The equipment should be installed with a foundation higher than the building ground. Generally, the foundation must be 30-50cm higher than the ground (large sterilizer). When there is no foundation, the UV disinfection equipment should be equipped with a bracket (small UV sterilizer). Choose the installation location reasonably. The part of the electric control cabinet is waterproof and moisture-proof.
5: Space considerations
From the single end of the UV sterilizer, there should be a space of the same length as the equipment to facilitate the replacement of the lamp tube. There should be 0.6 meters of barrier-free space in front of the control panel of the ultraviolet sterilizer for easy maintenance. The electric control box is installed near the device, the relative humidity of the environment is not more than 80 ℃, no corrosive gas, no conductive dust, no strong vibration and impact.
