Description

Technical Field

[0002] In the production and quality inspection of pump products, sealing performance testing is a crucial step to ensure their normal operation and service life. Currently, there are many types of pump products on the market, covering centrifugal pumps, gear pumps, piston pumps, and other types. Different types of pump products, and even different specifications of the same type, have significant differences in their inlet and outlet orifice diameters, ranging from a few millimeters to tens of millimeters.

[0003] In existing auxiliary tools for sealing tests of pump products, the size of the sealing head is often fixed, which can only be adapted to the inlet and outlet of pump products with specific orifice diameters. When sealing tests are required on pump products with different orifice diameters, operators have to frequently change the corresponding sealing head. This not only increases the number of spare parts required for the tool and raises equipment costs, but also prolongs the test preparation time and reduces test efficiency. Therefore, an auxiliary tool for sealing tests of pump products is proposed. Utility Model Content
