Sprinklers lattice consists of a frame composed of 2000 * 6000mm.
Total of 260 nozzles. Spraying an effective area of about 2000 × 6000mm;
can be customized by user to select 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.
Device Mainly Used：
(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.
This 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:
This 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.
This device structure and function：
(1) Analog rain shower uses SUS316 # stainless steel production, fine
workmanship, with acid 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): nozzle made of SUS316 # stainless steel, acid 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
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.
Water supply parts
1): storage box with acid 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.
