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 a cid 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.

Artificial climate test chamber main technical parameters are as follows:

4,Shower simplified schematic of the device

Description: Spray equipment must meet the minimum distance H from the product installation is not less than 1.5 meters, and can be lowered to meet the requirements of the tender technical documents rainfall.

5, the device structure and function: (1) Analog rain shower uses SUS316 # stainless steel production, fine workmanship, with a cid and alkali salt corrosion function, inlaid ruby set within the nozzle, its continuous life of up to 5--10 years. (2) the nozzle structure unique design, so that the ejection discontinuous lines (like rain) horizontal distance of no less than six meters mist spray direction ± 30 ° horizontal angle adjustable electric control, frequency control and electromagnetic valve control combination, simulated rainfall between 0.2 ~ 250mm (fog, rain, moderate rain, heavy rain, heavy rain, torrential rain) from arbitrary stepless adjustment. According to the needs of the future of the device may also be upgrading, but also to simulate the contamination, dust, frost and snow and other natural disaster conditions. (3) Device Structure The water spray system means a combination of the following three part together.

1, the nozzle lattice 
1): nozzle made of SUS316 # stainless steel, a cid salt corrosion resistance is strong. 2): Sprinklers and water pipes using dental wire connection, easy to remove, replace, easy cleaning and maintenance. High-fiber plastic pipes high pressure (high voltage: 35kV above) hose, wear compression 3): Sprinklers Yang, overlooking the angle formed by the low-speed motor drive control, accurate angle. 4): Sprinklers lattice frame of electrically controlled in both directions of rotation axes ± 90 degrees to achieve the level of the vertical jet spray rain rain needs. 5): each row (10 nozzles) each controlled by an electric switch valve, a total of 26 electric switch valves. 6): The spray wipers and the chassis between high voltage insulation fashion.

2, the electrical control part Using high-quality contactors, solenoid valves and other electrical components and high-performance inverter and the motor, precise electrical control logic design; aesthetic and practical computer fully automatic monitoring and control console, operated freely, safe, reliable, unified console is placed in the control room.

3, part of the water supply 1): storage box with a cid salt SUS316 # stainless steel materials, stainless steel cabinet thickness is 2mm. Together with the observed water level meter, which can effectively ensure the data collected spray. By the end of a drain tank easy to clean. According to the need to complete the appropriate size of the storage tanks. 2): The flow rate 8m3 / h, head of 25 m small pump spray pressure and heat, and to adjust the frequency control, to ensure that simulate spray 0.2 ~ 250mm rainfall precise control. 3): Water filtration apparatus part to be installed to facilitate maintenance (filters, etc.) and purification devices to ensure water is not blocked by debris or scale.
