For further improving explosion-proof effect; Level is provided with Explosion-resistant pale in said air outlet, between air inlet bellows and air-strainer, Explosion-resistant pale is installed, and said Explosion-resistant pale comprises frame; Be arranged with the number of metal sheet in the frame in parallel, leave the gap between the adjacent metal sheet.During the diesel engine proper functioning; Exhaust is flowed out from the gap between the tinsel, and when right your phenomenon of bag took place diesel engine, tinsel played the retardance air-flow; Avoid detonation air-flow fast to break through the water seal in the waste gas treatment case, and cause high temperature gas flow to flow directly in the working environment.
For realizing automatic water-supply, be provided with floating ball valve of rehydration in the said waste gas treatment case, the import of floating ball valve of rehydration links to each other with water supply tank on being arranged on car body through pipeline.When waste gas treatment case middle water level reduced, floating ball valve of rehydration was opened moisturizing automatically.
For reducing the tube wall temperature of outlet pipe and bellows, said outlet pipe and bellows are bimetallic tube, and the centre is provided with chuck, and said chuck is connected with the cylinder of diesel engine cooling water channel.Diesel coolant can pass through cylinder cooling water channel, chuck cooled exhaust pipe and bellows, and the tube wall temperature of outlet pipe and bellows is reduced to below 150 ℃.
The utility model anti-explosion diesel engine configuration anti-explosion diesel engine automatic protection device, and configuration portable gas explosion detection alarm appearance.Reach 93 ± 2 ℃ or maximum surface temperature and reach 148 ± 2 ℃ or engine oil pressure and be low to moderate 0.10 ± 0.01Mpa or waste gas treatment case water level most when being low to moderate 80mm most when the anti-explosion diesel engine delivery temperature reaches 68 ± 2 ℃ or coolant water temperature; Automatic safety device receives signal; Start working and send the sound and light signal warning, the time-delay rear electromagnetic valve is closed, and cuts off oil circuit and forces anti-explosion diesel engine to stop automatically; Has the reliability height, characteristics such as working service convenience.
The utility model anti-explosion diesel engine be a kind ofly with diesel oil be that fuel, reciprocating piston type internal compression are lighted, array, water-cooled, four-stroke, direct injection ic engine, be mainly used under the coal mine, but forbid in gas density reaches 1% environment, to turn round.
Beneficial effect: the utlity model has power foot, consume oily province, characteristics such as compact structure, torque reserve are big, stable performance, have good power character, Economy, reliability.
