Hydraulically started high pressure common rail electronic injection explosion-proof diesel engine system

Abstract

The invention discloses a hydraulically started high pressure common rail electronic injection explosion-proof diesel engine system. The hydraulically started high pressure common rail electronic injection explosion-proof diesel engine system comprises an explosion-proof electronically controlled diesel engine host, a hydraulically started system, a mine explosion-proof and intrinsic safety type high-pressure common rail diesel engine fuel injection control system, a double-layer cooling exhaust pipe with a water jacket, a spiral pipe cooling device, an acoustic resonance suppressor and a five-time flame arrestor. According to the invention, the system has the following beneficial effects: a double-layer cooling elbow is provided, gas discharged from an explosion-proof diesel engine main body is cooled for the first time through the double-layer cooling elbow, and then after being washed by an exhaust cooling device and cooled for a plurality of times by an exhaust fence flame arrestorand a cooling system, the gas enters the outside atmosphere, so the the exhaust gas temperature can be reduced below the standard requirement of 40 DEG C effectively. With a compact structure and good cooling effect, The the cooling form can adapt to a main cabin of a monorail crane, and a hydraulically started and extinguished system is adopted, the generation of electric sparks is fundamentallyeliminated, and the system adapts to underground transportation conditions effectively.

Description

technical field [0001] The invention relates to a high-pressure common rail explosion-proof power system, in particular to a hydraulically activated high-pressure common-rail electric injection explosion-proof diesel engine system, which belongs to the technical field of explosion-proof diesel engine systems. Background technique [0002] At present, monorail cranes are becoming more and more popular and applied as efficient underground auxiliary transportation equipment. The most important part of using monorail cranes to transport equipment is the power source. [0003] Existing explosion-proof diesel engine systems have high energy consumption and poor pollutant discharge, and usually have two radiators and make-up water tanks. On the one hand, the cooling effect of this structure is poor, and the exhaust temperature is too high; on the other hand, most of them use electric start Or the gas motor motor is used to start and stop the explosion-proof diesel engine, which can...

[0003] Existing explosion-proof diesel engine systems have high energy consumption and poor pollutant discharge, and usually have two radiators and make-up water tanks. On the one hand, the cooling effect of this structure is poor, and the exhaust temperature is too high; on the other hand, most of them use electric start Or air motor motor to start and stop the explosion-proof diesel engine, which cannot be used underground with high gas
