1, equipment specifications: 
(1)Specifications: Sprinklers lattice consists of a frame composed of 2000 * 6000mm. A total of 260 nozzles. Spraying an effective area of about 2000 × 6000mm; can be customized by the user to select the actual requirements. 
(2) precipitation adjustable operating range 0.2 ~ 250mm. 
(3) pump motor: Power 5.5kW, voltage 380V, 3-phase AC. Down range can simulate rainfall stepless adjustment from 0.2 to achieve any water between 250mm. Rain test cycle time can be arbitrarily set, test time. Environment simulator spray effective area of about 2000 × 6000mm, the nozzles fine workmanship, with acid and alkali salt corrosion function. Environmental simulation device before the water purification equipment device is configured, can achieve purification equipment, to avoid clogging the spray apparatus.

2, the device Scope: 
(1)Rain spray equipment suitable for high-speed rail EMU roof water and wet test. Trains, planes, automobiles, electrical equipment and outdoor products operation of the equipment; quality control oversight bodies identified measuring and testing, electrical equipment factories, railways and communications, aerospace and aerospace vehicles, military research institutes, universities and building and meteorological departments charged environment simulation assessment test. 
(2) spraying equipment to ensure the long rain 6m, continued even lower over a wide range of 2m rain droplets, raindrops small uniform.

3, the device achieved rain conditions: When the device is working within the effective area must meet the following table (GB / T 16927.1-2007- general requirements for high-voltage test) requirements of all the rain. Capable of artificial rainfall, salt fog, snow, ice and other environmental conditions and natural disasters, the impact study under different environmental conditions for high-voltage operation of equipment, focused mainly rain and salt spray test environment.
