Problems solved by technology
With the increase of the loading pressure, the former can no longer meet the requirements of the cylinder seal, the high pressure oil leaks, the loading is not stable, and the test cannot be carried out normally.
The latter can meet the sealing requirements, but the loading simulation of the cylinder head is quite different from the real machine state, and cannot truly reflect the stress state of the cylinder head

The invention provides a mechanical fatigue test device for a cylinder seal, which comprises a cylinder head, a cylinder gasket, a body, a cylinder liner, a piston, a piston pin and a sealing ring; On the side wall; the cylinder gasket is ring-shaped and is arranged on the outside of the upper end of the cylinder liner. The cylinder gasket includes a base and a rubber layer fixed on the outer surface of the base; the cylinder head is fixed on the body, and is The upper end is sealed. The cylinder head is provided with a high-pressure oil loading inlet connected to the cylinder inner cavity; the piston is installed in the cylinder liner and sealed with the cylinder liner by a sealing ring. The upper end of the piston cooperates with the cylinder liner and the cylinder head to form a combustion chamber. A piston pin is installed at the lower end of the piston. The mechanical fatigue test device for the cylinder seal of the invention not only solves the problem of the effectiveness of the cylinder seal in the test process, but also solves the problem of the inconsistency between the state of the cylinder head in the loading simulation and the actual machine.
Description
technical field [0001] The invention belongs to the technical field of cylinder seal test devices, in particular to a cylinder seal mechanical fatigue test device. Background technique [0002] At present, during the mechanical fatigue test of the cylinder head, the main measure for the cylinder seal is to use an annular gasket or rubber ring to seal. With the increase of the loading pressure, the former can no longer meet the requirements of the cylinder seal, the high pressure oil leaks, the loading is not stable, and the test cannot be carried out normally. The latter can meet the sealing requirements, but the loading simulation of the cylinder head is quite different from the real machine state, and cannot truly reflect the stress state of the cylinder head. Contents of the invention [0003] In view of this, the present invention aims to provide a mechanical fatigue test device for cylinder seals to effectively solve the key problems of cylinder seals in the current ...
