Description

Technical Field

[0001] The invention belongs to the technical field of testing equipment, in particular to a sealing detection electrical testing equipment. Background Art

[0002] Sealing test is an important part of product testing, which has a vital impact on the service life, safety and reliability of the product. As the country pays more and more attention to product quality, the standards for sealing test are also gradually improved. Sealing test is a method used to measure and test the sealing performance of products, mainly used to test the sealing performance of plastic products, pipes, tanks, etc. Sealing test can determine the sealing performance of an object, so as to ensure that the sealing performance of the object meets the set standards, thereby ensuring the normal use of the product. Good sealing performance effectively prevents external substances such as water and gas from entering the product, avoiding product damage or performance degradation, thereby ensuring product quality. Products with poor sealing are easily affected by the external environment, accelerating the aging process of the product and shortening its service life. Therefore, sealing test is an important means to improve the service life of products. For products involving water, gas and other media, the quality of sealing performance is directly related to personal safety, so sealing test is an important measure to ensure personal safety.

[0003] In mechanical manufacturing, some equipment or parts need to ensure their sealing before they can be used. Therefore, after production, their sealing needs to be tested. The equipment test bench for testing the performance of the equipment needs to be cooled with water during operation to maintain a stable and lasting working state. Patent CN200710145923.6 also discloses a hybrid vehicle drive motor test bench and test method. The motor test system includes a water cooling system. Parts detection is generally a detection method that fills a certain pressure of detection gas at the reserved interface after sealing all openings of the parts, and then uses detection means to observe the weld or interface. The traditional sealing detection equipment immerses the parts into the preset position of the water tank and inflates the parts. By detecting whether there are continuous bubbles around the parts, it detects whether the parts are leaking. In this way, no matter how large the leakage of the parts is, the parts need to be immersed in water before detection, which will result in a long detection time and low detection efficiency.
