High-pressure common rail explosion-proof diesel engine system

Abstract

The invention relates to a high-pressure common rail explosion-proof diesel engine system which comprises an explosion-proof diesel engine main body, a high-pressure common rail system, an air filter,an explosion-proof supercharger, an intercooling device, a tail gas treatment box and a radiating water tank, wherein all components are connected through multiple gas pipelines and multiple water pipelines; and the intercooling device and the radiating water tank are integrally mounted. According to the invention, explosion-proof transformation is carried out on the high-pressure common rail explosion-proof diesel engine system widely used on land to enable the high-pressure common rail explosion-proof diesel engine system to be suitable for borehole operation so as to form a novel high-pressure common rail explosion-proof diesel engine system; the high-pressure common rail explosion-proof diesel engine system has the advantages of saving energy and reducing emission, lowering the noiseand improving the safety performance; and through strict control of various parameters, efficient and environmentally-friendly operation of borehole operation is realized.

Description

technical field [0001] The invention relates to a high-pressure common rail explosion-proof diesel engine system. Background technique [0002] The fuel injection system adopted by high-power diesel engines, the first generation is the control mode of mechanical fuel injection pump and governor, the fuel injection quantity is controlled by changing the position of the fuel injection pump rack through the governor, and the high pressure of the injection is generated by the oil pump cam; the second Instead of the control mode of the electronically controlled fuel injection pump and the electronically controlled fuel injection controller, by controlling the opening time and duration of the solenoid valve of the electronically controlled pump, the fuel injection start point and fuel injection volume can be flexibly controlled, and the high pressure of the injection is generated by the fuel pump cam. [0003] The latest fuel injection technology is the third-generation high-press...

AI Technical Summary

Problems solved by technology

[0011] Since the high-pressure common-rail diesel engine system has been used on land, and the effect is better, but the equipment operating under the environment is generally equipped with a traditional diesel engine system, so how to carry out the explosion-proof of the high-pressure common-rail diesel engine system that has been widely used on land It is especially important to form a new high-pressure common rail explosion-proof diesel engine system for underground operations
