Directional explosion venting type mining diesel engine explosion-proof test bin

Abstract

The invention belongs to the technical field of explosion-proof performance testing of diesel engines for coal mines, and relates to a directional explosion venting type mining diesel engine explosion-proof test bin. The test bin comprises an explosion bin, an explosion-proof diesel engine and a dynamometer; the explosion bin is a closed box body, the top of the explosion bin is sealed through a plastic film, explosion waves and flames are instantly vented and released from the top in the experiment process, and the influence on the surroundings and noise are small; the explosion-proof diesel engine is arranged in the explosion bin, the dynamometer is arranged outside the explosion bin and connected with the explosion-proof diesel engine, and the dynamometer is independent of a sealed gas environment, so that the test safety is improved; and a detection device for monitoring the temperature and the pressure in the explosion bin and the operation condition and the explosion process of the explosion-proof diesel engine in real time is arranged in the explosion bin. The bin top of the test bin of the invention is sealed by the plastic film, explosive waves and flames are instantaneously released from the top in an explosion venting manner in the experiment process, and noise and influence on the periphery are greatly reduced; and the loading dynamometer is independent of the sealed gas environment, so that the test safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof performance testing of diesel engines used in coal mines, and in particular relates to an explosion-proof test chamber for directional explosion-venting type mine diesel engines. Background technique [0002] Auxiliary transportation equipment powered by mining explosion-proof diesel engines is widely used underground in coal mines, and is an indispensable auxiliary transportation equipment for intensive and efficient mining of coal mines. Due to the existence of gas in coal mines, the safety of explosion-proof diesel engines for mines is very important, and the inspection of their explosion-proof performance is an indispensable means for equipment safety access and scientific research. The coal industry standard MT990-2006 "General Technical Conditions for Mining Explosion-proof Diesel Engines" puts forward requirements for the complete explosion-proof performance test of mining diesel en...
