1. Use of IP waterproof test equipment
IP The waterproof test equipment needs to be combined with the corresponding product mold during use. The relative level of waterproof testing for mobile phones is not very high. The waterproof level is generally IP66. However, the waterproof level requirements for military auto parts, military mobile phones, military radio equipment and lighting equipment are very high, and the waterproof level of military products is generally IP68/IP69. The general waterproof testing equipment for such waterproof level is It is difficult to meet the requirements, so I will use a customized waterproof testing equipment for military industry from Jingcheng Engineering. There are generally no special requirements for products such as civilian auto parts, civilian household appliances, and outdoor lighting equipment. Such waterproof grades are generally in the IP66 can meet the requirements of on-site use. Most of the requirements of LED underwater lighting products meet the requirements of IP68, which is close to the requirements of military products. For some special occasions and high standard requirements, it is necessary to use special testing instruments Product for testing.

Second, the accuracy requirements of IP waterproof test equipment
Accuracy is the primary condition of the instrument, and IP waterproof test equipment is no exception: the precision unit of the waterproof tester generally adopts Pa, such as the waterproof test of the battery pack, the accuracy requirements of the IP waterproof test equipment used are very high. Because of The volume is relatively large, and the internal space is also quite large. It is tested with IP waterproof testing equipment. Since it only leaks a little air, the change of internal pressure is not obvious, so it is difficult to sense the change of pressure when the accuracy is not high. It is impossible to accurately detect the waterproof level of IPX6 and IPx7 of the battery pack.
3.Test standard for IP waterproof test equipment
IPX3 waterproof test equipment is to choose a pendulum tube with an appropriate radius, so that the height of the sample table is at the diameter of the pendulum tube, and the sample is placed on the sample table so that the top The distance to the water spray port of the sample is not more than 200mm; test conditions: the water flow rate is calculated according to the number of water spray holes of the swing pipe, and each hole is 0.07 L/min. When spraying water, spray water from the water spray holes in the 60° arcs on both sides of the midpoint of the swing pipe to the sample. The sample to be tested is placed in the center of the semicircle of the swing tube. The pendulum swings 60° on both sides of the vertical line, 120° in total. Test time: continuous watering for 10 minutes. The IPX4 waterproof test equipment is to choose a pendulum tube with an appropriate radius, so that the height of the sample table is at the diameter of the pendulum tube, and the sample is placed on the sample table so that the distance from the top to the water spray port of the sample is not greater than 200mm; test conditions: water The flow rate is calculated according to the number of spray holes of the swing pipe, and each hole is 0.07 L/min. The water spraying area is the water spraying holes in the 90° arcs on both sides of the midpoint of the pendulum pipe to the samples. The sample to be tested is placed in the center of the semicircle of the swing tube. The swing pipe swings 180° along both sides of the vertical, about 360° in total. Test time: continuous watering for 10 minutes.
Four. Product features of IP waterproof test equipment
1. Model structure of IP waterproof test equipment: it adopts double column structure, which is easy to install and the swing tube rotates smoothly .
2. The bottom of the IP waterproof test equipment adopts casters with adjustable foot cups, which is convenient for moving and adjusting the level of the machine.
3. A water tank is installed in the chassis of the IP waterproof test equipment, and the water level float valve is installed in the water tank to automatically control the water intake, and there are high and low water level alarm detection, which can effectively prevent the water pump from being damaged due to water shortage.
4. IP waterproof test equipment touch screen control + Panasonic PLC;
5. IP waterproof test equipment control function: swing tube flow and pressure manually adjustable, swing tube rain action control, stage action control , Test time control;
6, IP waterproof test equipment test time can be set 0-999M adjustable, one-button start, automatic shutdown
7, IP waterproof test equipment protection function: leakage protection, overload protection , Short circuit protection;
8. Stainless steel pendulum tube for IP waterproof test equipment; pendulum tube drive: imported servo motor (servo motor has the advantages of low noise, accurate speed and angle).
5. Several requirements for IP waterproof testing equipment
1. The efficiency of waterproof testing
With the development of industry and the increase of cost, many of companies have made efficiency a top priority. Then the air tightness testing, waterproof testing, and sealing testing industries are no exception. The air tightness and waterproof detector that can realize automatic detection and intelligent detection has attracted more attention from all aspects. Therefore, the waterproof detector should have the function of automatic air tightness leak detection.
2. Waterproof detectorPositive and negative pressure function
With the increasing complexity of products, some products are not suitable for positive pressure detection, and some are not suitable for negative pressure detection, and the airtight and waterproof tester with integrated positive and negative pressure functions It is the demand in the market today, and it is suitable for more and more complex IP waterproof tests.
3. Requirements for the accuracy of waterproof testing
Pa is generally used as the unit of accuracy of the air tightness tester. Due to the relatively small volume of the bracelet and the small internal space, it is tested with a waterproof tester. Since it only leaks a little air, the internal and external pressure balance has been reached. If the accuracy is not high, it cannot be accurately measured. Detect the waterproof level of IPX6, IPX7 of the wristband.
4. Requirements for the stability of the waterproof tester
The stability of the waterproof tester is related to the testing quality of the product. Therefore, an excellent waterproof tester and air tightness tester have better stability, which is an important technical indicator for it to occupy the market. How to ensure the stability of the waterproof test is particularly important. The important factor is the temperature, and the change of humidity will cause the sensitivity of the sensor, so the waterproof test equipment should have a temperature compensation control system, so that the change of temperature will no longer cause the instability of the test. .
