Description

Technical Field

[0001] The present invention relates to the technical field of sealing detection equipment, and in particular to a sealing detection equipment and a detection method which are easy to install and disassemble. Background Art

[0002] Most hose and metal tube sealing inspections are conducted at independent single stations, i.e. hoses are tested with hose equipment and metal tubes with metal tube equipment, resulting in high costs, large space occupation and single applicability. When conducting hose inspections, the hoses need to be placed one by one, manually debugged and clamped, and the operator is required to record the inspection results, resulting in slow inspection time and low degree of automation. When conducting large-scale inspections, production efficiency is low, and the operator's long and simple repetitive physical labor not only easily makes the workers tired, but also leads to missed inspections and misjudgments. At the same time, the equipment has a relatively single applicability and can only be used for one type of hose, with a short service life. Moreover, most pipe products use water testing equipment, which leads to a humid and harsh workshop environment, which is harmful to the workers' health. After the water test, there will be residual water inside the hose, which needs to be dried, affecting production efficiency. Summary of the Invention
