remaining 5 pcs of IPX5 spray nozzles are located in the middle of
the system, each capable of vertical (up and down) swinging with a
swing angle of ±15°.
3.There are 6 pcs nozzles in total, each equipped with a mechanical
flow meter, with individual flow meters controlling the flow for
each nozzle.

| Turntable system |
| Turntable diameter | 4000 mm |
| Turntable load | 1T |
| Turntable speed | 1～5 R/min (adjustable) |
| Water tank parameters |
| Water tank size | 1000×3000×1000mm(W*D*H) |
| Water tank material | SUS304 stainless steel |
| Water level | Transparent hose, with stainless steel ruler to observe water
level, ruler height 1.5m, ruler accuracy: 1mm |
| Water tank level control | Stainless steel float, overflow hole |

| Control System |
| Controller | 7-inch touch screen controller |
| Control System | This system is designed according to the technical requirements of
the rain test. The system is equipped with a manual control
function. |
| Manual control of the system | The logical operation of all electrical components in the spraying
system is controlled by PLC programming. The spraying time is
managed through a timer switch, and the duration can be adjusted as
needed |
| PLC System | 1) The PLC program should have reliable interlocking protection for
each action, and its peripheral circuit should have reliable
protection for PLC output. When electrical control fails, there
should be shutdown protection, signal display and alarm functions,
etc. Fuses should be set at PLC output points. 2) After each test, the nozzle starts from the bottom and has a
return to origin function; 3) Program operation mode: The total operation time can be set. In
the program of total time, the spraying time and moving distance of
a single point can be set. When the total test time is reached, it
can stop automatically. |
| Flow meter, pressure gauge control | Use mechanical flow meter and dial pressure gauge |
| Communication interface | Equipped with Ethernet interface, it can be connected to MES
system, and the test process can be viewed by those who monitor the
equipment online; the feedback includes test time, start, stop,
alarm information, etc. |
| Control cabinet | The control cabinet integrates XINJE PLC, and the circuit breakers
and electrical appliances are internationally renowned brands.
Buttons, LCD display screens, indicator lights and connection
terminals are all well-known brands. A three-color signal indicator
light is installed on the top of the cabinet to issue a warning
notice in the first place.
|
| Emergency stop button | 1) Set up an emergency stop button. It is required to be installed
in a conspicuous and easy-to-operate position. 2) The emergency stop circuit is composed of hardware and cannot
rely on the PLC stop circuit. 3) During an emergency stop, the control power supply, output power
supply, PLC input and output power supply, etc. are stopped. |
| Wiring process | It complies with international standards, with a well-organized
circuit board layout, secure wiring, and clear labeling. |
| Safety protection system | Power overload/short circuit protection, grounding protection,
phase loss protection, alarm prompt |
| The buyer shall prepare |
| Drainage channel | Water is not recirculated, needs drainage channel for water
drainage Dimensions of the drainage channel: Inner width: 300mm, Left depth: 200mm, Right depth: 300mm. The drainage channel should have a slope (see construction process
diagram for details). The sides and bottom of the drainage channel
must be covered with tiles.
|
| Power supply | The buyer shall prepare in advance 380V ±10% (three-phase,
five-wire system) power supply, with a dedicated 63A circuit
breaker. The air circuit breaker must have wiring terminals, and
the power cable should be at least 6m². Frequency: 50Hz ±10%,
approximately 10KW.
Temporary construction power supply: The buyer shall prepare in
advance 380V ±10% (three-phase, five-wire system) power supply,
with a dedicated 63A circuit breaker. The circuit breaker must have
wiring terminals, and the power cable should be at least 6m².
Frequency: 50Hz ±10%, approximately 20KW. |
| Water source | The buyer shall prepare the water piping in advance, leading the
pipeline with a diameter of 63mm or 100mm to the clean water tank. |
| Foundation and groundwork | The buyer is responsible for the foundation, while the supplier
provides the construction drawings. |
| Rain shower chamber | To prevent water from splashing out of the rain shower area during
testing, it is recommended to construct a protective barrier
outside the rain shower area. |
| Operating conditions of the equipment |
Environmental conditions
| Temperature: 15°C to 35°C; Relative humidity: 25% RH to 75% RH;
Atmospheric pressure: 86 kPa to 106 kPa.
|
| Inlet and outlet pipe diameter | For 1/2-inch pipes, please ensure the user plans the equipment
placement in advance and connects the inlet and outlet pipes
beforehand. |
| Power supply | 380V (three-phase, five-wire system), with a dedicated 63A circuit
breaker. The circuit breaker must have wiring terminals, and the
power cable should be at least 6m². Frequency: 50Hz; approximately
10KW (equipment power). |
