Waterproof testing device

1. Overview On

1. Purpose:

this machineUsed for external lighting and signal devices, as well as for the protection of automotive lamp housings, it can provide realistic simulation of various environments such as water and spray tests that electronic products and their components may be subjected to during transportation and use. To achieve the testing of waterproof performance of various products.

II. Principle:

This machine simulates spraying by using a swing rod. target, aim at, address, focus on, in response toProtection of electrical equipment with shell protection， Make reliabilityExperiment.

twoAccording to the standards

Applicable standards: GB shell protection standard.

fourInstrument installation

thistryThe inspection box is assembled and shipped as a whole, and does not require customers to install it themselves. The testing machine must be placed on a horizontal ground to prevent interference with the test and avoid displacement during high-speed vibration.

fiveTest steps

According to the experimental requirements, proceedtryAdd an appropriate amount of water into the inspection box. Place the test producttryBox inspection center, close the box door. pressPower on switch.

2Set the speed by rotating the knob on the panel.

3Set the interval time for rain, set the time, and turn on the interval switch. 99H80H is the rainy time, and 80H is the gap time. H represents "hour", M represents "minute", and S represents "second".

4Time setting: Set the time and turn on the timer switch. 999H80 is the time (automatic shutdown). H represents "hour", M represents "minute", and S represents "second".

5Set the water pressure by rotating the pressure adjustment knob to the appropriate position based on the reading on the pressure gauge

sixPrecautions

1The surface of the machine should be kept clean before and after use.

2Regularly check if all buttons on the panel are functioning properly.

sevenFault handling methods

1、 In the raintryCheck if the power supply is normal, if the phase sequence is normal, and if there is a neutral wire. 　

2、 Not exposed to rain: Check if the booster pump is working properly. Check if the nozzle is blocked.

3、 In the raintryThe box inspection should be managed and operated by a dedicated person, and the box body and blower should be cleaned regularlyRegular maintenance should be carried out by professionals.

4、 In order to perform stablytryThe function and performance of the inspection box should be selected with a perennial temperature between 15 and 25 degrees Celsius and a relative humidity of less than85% of the space.

5、 The distance between adjacent walls or objects. The environmental temperature of the installation site should not change rapidly. It should be installed in a place without direct sunlight, in a well ventilated place, away from combustibles, explosives, and high-temperature heat sources. The equipment should be installed in a place with less dust and as close to the power supply as possible.
