Description
Technical Field
The invention relates to the field of detection, in particular to a waterproof performance detection method and device.
Background
The water-resistance reflects the degree of protection provided by water entering the hazardous parts. The waterproof capability of the sealing box of the device is important for ensuring the safe operation and the service life of the product. The waterproof test simulates the destructive test of water on equipment in daily life, and the waterproof test is used for checking the waterproof capability of a shell, a protective cover, a sealing ring, a surface coating and the like of a product needing to be waterproof so as to ensure that the product cannot be damaged under the influence of water and after the influence. Long-time water logging can damage the outside combination of product, causes the lax, the crazing of structure, reduces the intensity of some materials, for example wire and cable insulation and restrictive coating insulating properties reduce, directly leads to the electrical insulation breakdown, and the product is damaged to light then the short circuit, and the conflagration is aroused to the heavy time. The protective performance of the shell of other products is poor, water directly enters the electrified part of the product to cause internal short circuit, and the product fails and cannot be used directly. Therefore, the waterproof performance is an important factor influencing the safety of equipment, and a water tank or a water pool needs to be matched for a water immersion test generally, but in the test process, if the waterproof requirement of the equipment reaches the requirement of the water depth of more than 2m or even 10m, the waterproof performance is limited by factors such as fields, and the waterproof performance cannot be matched with the water tank or the water pool with enough depth.
