Abstract

The invention discloses an intake-exhaust manifold of an explosion-proof diesel engine. The intake-exhaust manifold of the explosion-proof diesel engine comprises an intake pipe, an exhaust pipe and a cooling water channel, wherein the intake pipe and the exhaust pipe are a whole. The whole penetrates through the inner space of the cooling water channel, and a water inlet and a water outlet are formed in the cooling water channel. The intake-exhaust manifold of the explosion-proof diesel engine can reduce the gas temperature of the intake pipe and the exhaust pipe, thus safety performances of the intake pipe and the exhaust pipe are improved, and meanwhile, airflow resistances in the intake pipe and the exhaust pipe are reduced.

Description

A kind of anti-explosion diesel engine intake and exhaust house steward
Technical field
The invention belongs to the diesel engine part field, relate in particular to anti-explosion diesel engine intake and exhaust house steward.
Background technique
Because there are a large amount of flammable and explosive substances in Coal Mine Area, so the equipment that uses in this area all needs to take explosion precaution, otherwise easily cause accident of mine disaster.The motor that the equipment that uses at present uses, can produce a large amount of waste gas when especially diesel engine is worked, these exhaust gas temperature are very high, therefore the temperature of the exhaust duct of the diesel engine variation that can cold and heat succeed each other frequently, huge thermal stress can make outlet pipe crackle occur, thereby very easily causes accident of mine disaster.In the pipeline of the outlet pipe of simultaneously general cast iron manufacturing, gas-flow resistance makes more greatly exhaust efficiency low.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of anti-explosion diesel engine intake and exhaust house steward that can reduce delivery temperature safety.
Technological scheme: for solving the problems of the technologies described above, of the present invention just have a following technological scheme: a kind of anti-explosion diesel engine intake and exhaust house steward, comprise suction tude, outlet pipe and cooling water channel, described suction tude and outlet pipe are an integral body, this integral body is passed the inner space of described cooling water channel, and described cooling water channel is provided with water intake and water outlet.
When diesel engine is worked, as the gas in holistic suction tude and outlet pipe, carry out heat exchange by the cooling water in tube wall and cooling water channel, no matter be air inlet or exhaust thereby make, the temperature of gas has decline in various degree, makes diesel engine surface temperature and diesel engine combustion gas excess Temperature, causes outlet pipe to break, cause potential safety hazard, thereby provide guarantee to safety work under coal mine.
As preferably, described cooling water channel is provided with connecting head, and this connecting head is communicated with secondary water tank, thereby replenishes easily the cooling water in cooling water channel at any time.
As preferably, adopt stainless steel or aluminum alloy material to make, can reduce gas-flow resistance in the intake and exhaust house steward, can also reduce the weight of diesel engine itself.
As preferably, and the Effective face width of the explosion-insulation surface between diesel engine cylinder cover is more than 15mm; Described cooling water channel is provided with explosion suppresion surface, this explosion suppresion surface Effective face width more than 5mm, thereby further promote the explosion-proof performance of diesel engine.
The roughness of described explosion-insulation surface and explosion suppresion surface is less than 6.3 μ m.
Beneficial effect: compared with prior art, the present invention has the following advantages: reduce gas temperature in air inlet-outlet pipe, thereby improved its Safety performance; Reduce simultaneously the gas-flow resistance in suction tude and outlet pipe.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of anti-explosion diesel engine intake and exhaust house steward, made by aluminum alloy, comprise suction tude 1, outlet pipe 2 and cooling water channel 3, described suction tude 1 and outlet pipe 2 are an integral body, this integral body is passed the inner space of described cooling water channel 3, makes the gas by suction tude 1 and outlet pipe 2 carry out heat exchange by the cooling water in tube wall and cooling water channel 3, thereby reduces gas temperature; Described cooling water channel 3 is provided with water intake 4 and water outlet 5, and cooling water channel 3 also is provided with connecting head 6 simultaneously, and this connecting head 6 is communicated with secondary water tank, can replenish cooling water by secondary water tank in case of necessity; The explosion-insulation surface Effective face width of establishing between described anti-explosion diesel engine intake and exhaust house steward and diesel engine cylinder cover is more than 15mm, the explosion suppresion surface that contains cooling water channel 3 through holes in described explosion-insulation surface should be not less than 5mm by the inner Effective face width to the watercourse through-hole edge of junction plane.The surface roughness Ra of explosion-insulation surface and explosion suppresion surface is no more than 6.3 μ m, and this anti-explosion diesel engine intake and exhaust house steward is through the pressure test of 0.8MPa, keeps 30min, ne-leakage, without permanent deformation.
The present invention can be in gas density lower than 1% environmental work, and when diesel engine was worked, diesel engine sucked gas from suction port, from the relief opening combustion gas.In this crossed into, the cooling water from diesel pump is extracted out entered intake and exhaust house steward's cooling water channel 3 through water intake 4, and cooling water flows with water channel and represents the flow of cooling water direction as arrow in Fig. 1, then flows out to engine water outlet 5 from water outlet 5.No matter this process is also exhaust of air inlet if making, the temperature of gas has obtained reduction in various degree, thereby make the surface temperature of diesel engine and the temperature of diesel engine combustion gas be unlikely to too high, cause this device to use having under the mine of certain gas density, and very high Safety performance is arranged, provide sound assurance to safety work under coal mine.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
