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 ¡Á 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 ¡Á 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. |

5, the 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 ¡À
30 ¡ã 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, 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 ¡À 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 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. |
