Description

Square cooler core group hydraulic test tooling

technical field

The utility model relates to the field of a hydraulic test tool, in particular to a hydraulic test tool for a square cooler core group.

Background technique

The hydraulic test of the square cooler core group without end cover, if the hydraulic test tool is not manufactured, the hydraulic test cannot be carried out. The current test method is usually to make a matching end cover for the test or to make a square hydraulic test tool similar to the core group . Making end caps for hydrostatic testing is simple in structure, easy to manufacture, and low in cost, but it is impossible to check which heat exchange tube is leaking, which is not conducive to achieving the purpose of hydrostatic testing; making square hydrostatic test fixtures is relatively simple to manufacture. The price is also relatively cheap, the fit with the cooler is better, the installation is convenient, and it is possible to check which heat exchange tube is leaking, but the square pressure test tooling is easy to collide with the fins, and the seal between the square flange and the cooler tube plate Inconvenient, the square cylinder cannot meet the requirements and needs to be remade, which will increase the production cost and production cycle. The square cylinder needs more than two welds to complete, which can easily cause welding deformation and affect hydraulic assembly.

Utility model content

The utility model aims at the deficiencies of the prior art, and provides a hydraulic test tool for a square cooler core group. The technical solution adopted to solve the technical problem is: a square cooler core group hydraulic test tool, which is characterized in that it includes a flange and a cylinder, and the flange is a circular flange; the cylinder is a circle shaped cylinder; the flange is connected to the port of the cylinder; a square through hole is arranged in the middle of the flange, and the first threaded hole is arranged around the periphery of the square through hole; There is a second threaded hole.

Preferably, an O-ring is also included, and the O-ring is arranged between the flange and the port of the cylinder.

Preferably, the cylinder is a seamless steel pipe.

The beneficial effect of the utility model is that the circular cylinder tooling meets the high-pressure hydraulic test, the roundness of the cylinder can be effectively guaranteed, and the protection of the fins of the core group can be effectively controlled during the installation process; the seamless steel pipe is used, It is convenient for the assembly of the water pressure of the cooler; the O-ring can improve the sealing of the water pressure test; the process of the water pressure test can check which heat exchange tube is leaking.
