Modular and embedded body-heated constant-volume combustion bomb

Abstract

The invention provides a modular and embedded body-heated constant-volume combustion bomb, which comprises a constant-volume combustion bomb body (1) and a window adapter (2); the window adapter (2) is arranged on the constant-volume combustion bomb body (1); the constant-volume combustion bomb body (1) is provided with a window adapter mounting groove (16); the window adapter (2) is arranged in the window adapter mounting groove (16). Thirty-six heating holes are uniformly formed in twelve edges of the constant-volume combustion bomb body in the modular and embedded body-heated constant-volume combustion bomb, so that a heating rod is installed, and the constant-volume combustion bomb body is rapidly and uniformly heated. According to the constant-volume combustion bomb body in the modular and embedded body-heated constant-volume combustion bomb, the constant-volume combustion bomb body is provided with a wiring groove for wiring a heater, so that an aesthetic effect is achieved; meanwhile, the arrangement of a heat insulation plate on the constant-volume combustion bomb body is facilitated, thereby enhancing the heating effect.

Description

technical field [0001] The invention relates to the field of incendiary bombs, in particular to a constant-volume incendiary bomb with modularized and embedded body heating, and in particular to a constant-volume incendiary bomb for spray and combustion visualization tests. Background technique [0002] The combustion process of the internal combustion engine directly determines the thermal efficiency, emission and other performance of the engine. The research on spray and combustion is of great significance to the engine. The constant volume incendiary bomb is a visual experimental device used to study the spray and combustion performance of the internal combustion engine. It can effectively Various thermal parameters (pressure, temperature, etc.) of the engine are simulated, and the visualization research of the spray process and combustion process can be carried out by equipped with high-speed cameras and other equipment. It is suitable for various internal combustion engi...

Problems solved by technology

[0003] Chinese patent CN 105372072 A discloses a constant-volume incendiary bomb and a combustion device with the constant-volume incendiary bomb, which has a cavity inside as a cubic structure of the combustion chamber, has six working surfaces as the main mounting surface and is located at The auxiliary mounting surface processed on the eight top corners, but the constant volume incendiary bomb does not have the body heating function, and cannot effectively simulate the wall temperature when the engine is working, and at the same time, it is easy to condense water mist on the glass wall after combustion; in addition, the patent document The method of bonding the glass to the mounting seat limits the further increase of the internal pressure of the bullet due to the force on the bottom of the glass (easy to cause uneven local force) and the problem of glass sealing (high pressure gas is easy to leak from the outside of the glass base).
