5、设备结构及功能: This device structure and function

(1) 雨水模拟喷淋器采用SUS316^#不锈钢材质制作，做工精细，具有耐酸碱盐防腐蚀功能，喷头内套镶红宝石，其连续使用寿命可长达5-10年。

(2)喷嘴结构采用独特的设计，使其喷射不连续线状(雨点状)水平距离六米以内无水雾，喷射方向±30度水平角电控可调,变频控制与电磁阀控制结合,模拟降雨量从0.2～250mm(雨雾、小雨、中雨、大雨、暴雨、特大暴雨)之间实现任意无级调节。根据需求，以后本装置还可以改造升级，还能进行污秽、尘埃、霜冻及冰雪等自然灾害状况的模拟。

(3) 设备结构

本淋水系统装置由如下3部份组合而成。

(1) Analog rain shower uses SUS316 # stainless steel production, fine workmanship, with acid and alkali salt corrosionfunction, inlaidruby 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 lessthan sixmeters 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 simulatethecontamination, 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、喷头点阵 Nozzle lattice

1)：喷头采用SUS316^#不锈钢材质制成，耐酸碱盐防腐蚀性强。

2)：喷头与输水管采用丝牙连接方式，便于拆卸、更换、方便清洗及保养。输水管采用高纤维塑胶高压（高电压：35kV以上）软管，耐磨抗压

3)：喷头仰、俯角度由低速电机传动控制，角度**。

4)：喷头点阵框架可电动控制在两个方向轴上±90度转动，实现水平喷雨与竖直喷雨的需求。

5):每排(10个喷头)各由一个电动开关阀门控制，共26个电动开关阀门。

6):喷雨器与底架之间采用高压绝缘的方式连接。 

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-fiberplastic pipes highpressure (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 thevertical jet sprayrain 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、电气控制部分  Electrical control part

采用**接触器、电磁阀等电器元件和高性能的变频器及电动机，**的逻辑电气控制设计；美观实用的计算机全自动测控操作台，操纵自如，安全可靠，操作台统一放置在控制室。

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

3、供水部分 Water supply parts

1): 蓄水箱采用SUS316^#耐酸碱盐不锈钢材料，箱体不锈钢材料的厚度为2mm。配以水位观察计，能有效的保证喷淋数据的***。下底有排水口方便箱体清洗。根据需要配套相应大小的蓄水箱。

2): 采用流量8m³/h、扬程25米的小型水泵加压加温喷淋，并以变频调节控制，能保证模拟喷雨量在0.2～250mm**控制。

3): 供水部分需安装便于维护的过滤装置（过滤网等）及净化装置，确保水路不被杂物或者水垢堵塞。 

1): storage box with acid salt SUS316 # stainless steel materials, stainless steel cabinet thickness is 2mm. Together with theobserved water levelmeter, 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 storagetanks.

2): The flow rate 8m³ / h, head of 25 m small pump spray pressure and heat, and to adjust the frequency control, to ensure thatsimulate 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 wateris not blockedby debris or scale.
