QM-333 Test No.14 High Pressure Rain Test System 8 Nozzles Waterproof Testing Equipment
Standard:
QM-333” Standard for environmental testing of telecommunication equipment“ Test No.14
Sample scope, purpose, principle:
Samples and restrictions: wireless signal jammers, telecommunications equipment.
Test purpose: To test whether wireless signal jammers and telecommunications equipment can ensure good performance of equipment and components under high-pressure water spraying environment. The purpose is to verify the protective performance of the product's shell when exposed to rain according to QM-333 Test No.14.
Test principle: The equipment uses a lifting platform to fix the workpiece and controls the water supply pump head through PLC frequency conversion. Ensure that the 8-way nozzle meets the standard requirements for water pressure and total water supply flow, so that the test equipment can generate water flow or water pressure on the 4 sides and top surface of the sample shell. After the test time is completed, the water spraying stops automatically.
Structure:
This device consists of a stainless steel waterproof box, a water spraying mechanism, a liftable platform and an electrical control cabinet.
1. The waterproof box adopts a double-layer box structure, the inner box is made of 304 stainless steel, the outer box is made of cold plate paint, and transparent tempered glass is installed in the front and back. The bottom of the waterproof box is a water storage tank for water supply and return, which recycles the test water and has an automatic water replenishment device.
2. The 8-way nozzles are arranged as follows: one on each of the front, rear, left, and right sides, and one on each of the top four diagonals at 45° downwards, a total of 8 nozzles. A pressure gauge is arranged at the front end of each pipe to monitor the pipeline pressure. The side nozzle is located at the center of the side of the sample, and the top nozzle is located at the four diagonal positions of the top of the sample. The position of the nozzle can be appropriately adjusted to ensure that the distance between the nozzle and the sample surface is appropriate.
3. Use a liftable sample installation platform to match sample requirements of different heights, so that the side nozzle is always located at the center of the side of the sample. The supporting surface of the platform is a fence structure to avoid water accumulation.
4. The control cabinet is integrated with the waterproof box and arranged on the right side of the front of the waterproof box. It is controlled by Mitsubishi PLC and operated by touch screen. It can display test time, total test water flow, test status, alarm information, etc.
Technical Parameters:
| 1. Technical parameters of intelligent electrical control cabinet | |
| Electrical control cabinet | ◆Flow detection: electronic flow meter flow signal feedback. ◆ Pressure setting: Pressure setting on the screen of the control cabinet. ◆ Controller: Mitsubishi PLC. ◆ Human-machine interface: 7-inch, color touch screen. ◆ Control function: constant pressure water supply, water spraying on-off control, test time control. ◆ Protection functions: phase sequence protection, leakage protection, motor overload protection, short circuit protection, water shortage alarm and water pump dry burning protection. |
| Scope of application | Suitable for QM-333 waterproof test, water supply and control test |
| Water supply method | Constant pressure water supply |
| Water supply control process | After the user sets the pressure value on the touch screen, the electronic flow meter monitors the current value in real time, reads it into the PLC through data conversion, and then adjusts the water pump speed through the frequency converter so that the output water pressure meets the standard requirements. The flow rate is determined by the pressure and the nozzle, and can meet the standard requirements of about 450L/h. |
| High flow pipeline | ◆ Applied to QM-333 high-pressure water spray test; ◆ Flow range: 10-100L/min; ◆ Flow accuracy: ±0.5L/min; ◆ Flow meter: worm flow meter; ◆ Pressure sensor: 0~1MPa, 0.25 level accuracy ◆ Water pump: stainless steel water pump; ◆ Pipeline: The water supply of the equipment adopts stainless steel pipelines and is distributed to various parts of the equipment according to the on-site layout. It is controlled by the electromagnetic water valve at each equipment, and then connected to the box by a high-pressure hose. The water supply pipeline is equipped with a drain valve to automatically drain the water in the water pipe after the test is completed ◆ Filter: Fine filter element |
| 2. Technical parameters of stainless steel waterproof box | |
| Stainless steel waterproof box | ◆ The outer shell of the waterproof box is made of 1.2mm thick cold plate with baking varnish, and the inner box is made of 1.0mm stainless steel 304 plate with built-in reinforcement ribs; ◆ The inner volume of the waterproof box: greater than 500L, meeting the test requirements of 8 nozzles for 1h; ◆ The inner dimensions of the box: W1500XD1300XH1850mm. ◆ Observation window: tempered glass; ◆ Window size: W400XH500; |
| 3. Technical parameters of lifting platform | |
| Adjustable lifting height | 0-600mm adjustable |
| Material | 304 Stainless Steel |
| Dimension | Φ800mm |
| Loading | ＞100KG |
| 4. Technical parameters of QM-333 water spray mechanism | |
| Nozzle parameters | Refer to IPX9 nozzle production to ensure that the flow rate meets the requirements under 200kPa pressure |
| Water flow | Each nozzle 7.5L/min (about 450L/min), the total flow can be displayed |
| Pressure | 200Kpa, touch screen setting, pressure sensor range 0～1Mpa |
| Fixed location and method | The water spray nozzles are mechanically fixed on each bracket and arranged as follows: 1. 4 nozzles are arranged on the top, one on each diagonal (the reference object is the lifting platform), and the distance from the sample is 100-300mm adjustable 2. 4 nozzles are arranged on the side, centered in the front, back, left and right (the reference object is the lifting platform), and the distance from the sample is 50-150mm and can be fine-tuned
|
| Pressure gauge | 0~1MPa, can be displayed, one is installed in front of each nozzle |
| Test time | 0～99h59min59s, presettable |
