Abstract

The invention provides a sealing performance testing device and method. An object to be tested is placed in a testing container in a sealed mode, air in the testing container is controlled to be pumped out instantaneously, the sealing performance of the object to be tested is analyzed according to the change valve of air pressure, detected by an air pressure detector, in the testing container and preset detection standards to obtain the analysis result, and therefore the defects that a product is placed in water to detect the sealing performance of the product and consequently water permeates into the product and the product is damaged in the prior art are overcome. The device and method are convenient to use and easy to operate and provide convenience for detection of the sealing performance of the product.

Description

technical field [0001] The invention relates to the field of equipment performance testing, in particular to a sealing performance testing device and a testing method thereof. Background technique [0002] In life, it is often necessary to require high sealing performance for some products, such as vehicle camera lenses, motors, etc. In the prior art, the product is usually put into water to test its sealing performance, but not all products are suitable for putting into water Carrying out the test, taking the vehicle-mounted camera lens as an example, if it is put into water, it may cause water to seep into its interior, causing damage to the lens and increasing the manufacturing cost. [0003] Therefore, the prior art needs to be improved and developed. Contents of the invention [0004] The object of the present invention is to provide a sealing performance testing device and a testing method thereof in view of the defect in the prior art that the product is put into...
