ZH-1023 Rainy Experiment Device for Central Air Conditioning External Unit
1、 Overview:
The IPX3-6 showerhead rain test device is designed and manufactured according to the requirements of IEC60529:1989+A1:1999+A2:2013 “Degrees of protection provided by enclosures (IP Code)”, GB/T 4208-2017 “Degrees of protection provided by enclosures (IP Code)”/IEC 60529:2013 “Degrees of protection provided by enclosures (IP Code)”, clause 14.2 (IPX3-6 showerhead test and nozzle test), and UL 50E-2007 “Enclosures for Electrical Equipment, Environmental Considerations” (electrical equipment enclosures, environmental factors), and is used for IPX3-4 showerhead test and IPX5-6 nozzle test. UL water spray test (clause 8.3).
This complete set of equipment consists of 4 sets of electric brackets that can be moved up, down, left, and right, 6 showerheads, 1 nozzle, a water supply system, a control system, and a UL spray test device. Automatic frequency conversion regulation of water flow technology, simply select the nozzle input to test the total flow rate on the interface, and it can automatically meet the corresponding IP water flow requirements and simulate the blowing state.
2、 Technical requirements：
| 1 | Rainy surface | Five faces: front and back, left and right, top |
| 2 | Shower spray bracket | There are 4 brackets, each of which can adjust the position of the showerhead up and down |
| 3 | Number of showerheads | There are a total of 6, and when that side needs to be sprayed, move it to that side for spraying。 |
| 4 | spray nozzle（IPX5、6） | 1 It can be fixed on a spray bracket |
| 5 | ULwater spray | 4A nozzle |
| 6 | Method of fixing showerhead | The showerhead is fixed on the spray bracket and secured to the bracket with fixtures, allowing for adjustable height for easy testing。 |
| 7 | Flow control of each showerhead nozzle | The system is equipped with 4 water supply channels, each of which can monitor the flow rate separately. When the water pump is started, the flow rate of each channel is adjusted through a throttle valve。 |
| 8 | Spray angle adjustment | Manually adjust, adjust the spray angle before the experiment。 |
| 9 | pressure control | Depending on flow control, the pressure is within the range of 30-150kPa。 |
| 10 | time control | Total experimental time control, with in Touch Screen Set the test time and automatically stop when it arrives。 |
| 11 | Number of water pumps | 1 tower |
| 12 | Number of water tanks | 1 piece |
