IPX1 - IPX4 Comprehensive Test Chamber Integrated With Drip Box And Oscillating Tube

IEC60529 IPX1 to IPX4 Comprehensive Test Chamber, Integrated with Drip Box and Oscillating Tube

1. Introduction:

IPX1-4 waterproof test chamber combines the oscillating tube and drip box in one system, it meets the requirement of IEC60529 regarding the IP level IPX1, IPX2, IPX3 and IPX4. Waterproof test simulates the condition of dripping water, splashing water and spraying water, which is mainly applied to electronic products, luminaire, electric components, motor and house-holding appliance. The waterproof test can help to judge the products’ performance, and provide the basis for design, improve and inspect.

The comprehensive test chamber is consisted by oscillating tubes (R600), drip board (L600mm*W600mm) turntable, water tank, control units (touch screen+PLC), flowmeter and etc.. The oscillating tube, drip board, turntable and walls are made of SUS304 stainless steel. The test chamber is built-in a water tank, the water can be recycled. 4 casters are placed on the bottom of the chamber to make it can be moved easily.

For IPX3 test, the oscillating tube has spray holes over an arc of 60⁰ either side of the centre point (the other holes are blocked), the total flow rate is adjusted as standard requirement, the enclosure to be tested is placed at the center point of the semicircle, the tube is caused to oscillate through an angle of 120⁰, 60⁰ on either side of the vertical, the time for one complete oscillation (2*120⁰) being about 4s and test duration being 5min.

For IPX4 test, the oscillating tube has spray holes over the whole 180’’ of the semicircle, the total flow rate is adjusted according to the standard requirement, and measured with a flowmeter. The tube is caused to oscillate through an angle of almost 360⁰, 180⁰ on either side of the vertical, and time for one complete oscillation (2*360⁰) being about 12s. The duration of the test is 10min.

For IPX1 and IPX2 tests, the aperture of nozzle is Φ0.4mm, distant of drip nozzle is 20mm. The IPX1 test requests the dripping water (vertically falling drops) shall have no harmful effect, test duration: 10 minutes, equivalent to 1 mm / minute. The IPX2 test requests vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position, test duration: 10 minutes (2.5min in each of 4 fixed positions of tilt), water equivalent to 3 mm/minute.

2. Features:

● For IPX1, IPX2, IPX3, IPX4 testing

● The inner wall of the equipment and turntable are made by SUS304# stainless steel, to ensure rustless.

● The water supply pipeline is equipped with a filter, which can filter the impurities in the water and prevent the nozzle from being blocked.

● The water tank is built-in the equipment, the water can be recycled. Auto to control the water level with the help of Water floating ball valve, and alarm at high or low level to protect from the damage caused by low water level.

● The drip board for IPX1 and IPX2 tests adopts vacuum design and is made of high anti-rust stainless steel material. It also has the function of air-drying with compressed air, after the test is completed, the excess water in the drip box can be drained out to avoid long-term accumulation of water and scaling and clogging of pinholes ( air compressor is prepared by user).

● Oscillating tube drive: Adopts Chinese branded step motor, with features of low noise and high accuracy. The speed and rotate angle of oscillating tube are precision adjustable.

● Turntable drive: adopts Chinese branded step motor, can adjust the speed and angle by touch screen, and auto control the directions (fit for the samples to do live test).

● The sample power socket (AC220, 10A) is installed on the wall, and the power on and off time of the sample power can be controlled by the program: power off (0-999min)-power on (0-999min)-power off (0-999min), it is applied to do live test.

● Time setting for power: power off: 0-999min-power on: 0-999min-power off: 0-999min

● Control components: 7 inch touch screen+ Panasonic PLC. The electrical components are made by LS, Omron, etc. The wiring process meets the requirements of Chinese national standards, the layout of the electric board is reasonable, the wiring is firm, and the marking is clear.

● Preset IPX1, IPX2, IPX3 and IPX4 test procedures, users only need to select the waterproof level, and the equipment will perform the test in accordance with the standard requirements.
