New energy automobile cooling water pump sealing performance detection structure

Abstract

The invention relates to the field of water pump detection, and in particular, relates to a new energy automobile cooling water pump sealing performance detection structure which comprises a structure shell, a hydraulic cylinder and a steam generator are fixedly welded to the top end face of the structure shell, a hydraulic rod is connected to the output end of the hydraulic cylinder, and a mounting plate is fixedly welded to the bottom end of the hydraulic rod; the mounting plate is slidably connected into the structural shell in a limiting manner, a driving assembly and a detection assembly are mounted on the mounting plate, a fixed bottom plate is fixedly welded to the bottom end face of the interior of the structural shell, a clamping and positioning assembly is mounted in the fixed bottom plate, and a first sealing assembly is mounted on the driving assembly; a second sealing assembly is mounted at the bottom end of an elastic telescopic hose, and the elastic telescopic hose is fixed to the mounting plate through bolts; and the problems that an existing detection structure cannot conduct rapid, accurate and visual detection analysis and comparison work on the sealing performance of a water pump to be detected in the using process, and practicability is poor are solved.

Description

technical field [0001] The invention relates to the field of water pump detection, in particular to a new energy vehicle cooling water pump sealing performance detection structure. Background technique [0002] With the development of science and technology, the automobile field is undergoing scientific and technological reforms. In order to reduce the use of gasoline, many automobile manufacturers have launched new energy vehicles, thereby fundamentally solving the pollution of automobile exhaust. However, among the many components of new energy vehicles, cooling The water pump is one of the essential parts, and after the cooling water pump is produced and processed, in order to check the sealing qualification of the cooling water pump, it is necessary to use the sealing test structure to test the sealing qualification of the cooling water pump, and the current sealing There are still some problems in the use of the detection structure; [0003] For example, the publicatio...

AI Technical Summary

Problems solved by technology

[0003] For example, the publication number is CN109556804A, a kind of one-way valve leak detection device, "comprising a base, an air inlet and an exhaust hole are arranged on the side of the base, a pressure gauge is connected outside the exhaust hole, and a pressure gauge is arranged on the upper surface of the base. There is an installation groove for installing the air inlet of the one-way valve, ..., there are also a large O groove and a small O groove surrounding the installation groove on the upper surface of the base, and a large sealing ring is arranged in the big O groove, A small sealing ring is arranged in the small O groove, and the edge of the bell jar is pressed on the upper surface of the large sealing ring, and the upper surface of the small sealing ring is attached to the one-way valve. Although this device can quickly and accurately detect The sealing performance of the one-way valve with the gas port located on the side, but it cannot perform fast, accurate and intuitive detection, analysis and comparison of the sealing performance of the valve or water pump to be tested during the working process, and the practicability is poor. Therefore, it is necessary to provide a New energy vehicle cooling water pump leak detection structure to meet the needs of users
