Abstract

The invention relates to a diesel, in particular to an explosion-proof diesel, which is applicable to anti-explosion power devices on various fixed and mobile equipment underground coal mine, solving the problems that no explosion-proof diesel product exists in domestic market, while the imported explosion-proof diesel has complicated structure, high price, long lead time of components and parts, untimely service, high maintenance costs and the like. The invention comprises a diesel body, a cooling system, a fuel supply system, an exhaust system and an air intake system, wherein, the cooling system, the fuel supply system, the exhaust system and the air intake system are connected with the diesel body assortatively; an exhaust manifold and an exhaust pipe in the exhaust system are all provided with water jackets; an outlet of the exhaust pipe is connected with a waste gas processing box; the air intake pipeline of the air intake system is provided with an air intake barrier; the invention is further provided with an air starter and protection system. The invention solves the problems of difficult assortment, difficult maintenance and long period of vulnerable components of imported machine types; the air starter and protection system adopts a compressed air starter to start and has the advantages of safety and reliability, convenient maintenance under the mine; the air exhaust is safer and the discharging is effectively reduced.

Description

technical field [0001] The invention relates to a diesel engine, in particular to an explosion-proof diesel engine, which is used as an explosion-proof power device for various fixed and mobile equipment in underground coal mines. Background technique [0002] In foreign countries with advanced coal mining technology, trackless auxiliary transportation technology has been widely used. In recent years, some modern large-scale mines and reconstructed and expanded mines in my country have also actively practiced and promoted these aspects, and achieved good results. It embodies the characteristics of high efficiency, multi-purpose, flexible maneuvering, high transportation efficiency and advanced technology of trackless auxiliary transportation, and plays a powerful role in promoting the development and innovation of trackless auxiliary transportation rubber-tyred vehicles in my country. [0003] In modern large-scale coal mines, the materials required for underground equipmen...
