Abstract
The utility model relates to a gas engine. An engine body (6) is equipped with a shaft (5) which is equipped with a multi-stage active compressor impeller (2) at the middle portion; the inner side of the engine body (6) is equipped with a multi-stage passive compressor impeller (1); one end of the engine body (6) is fixed with a multi-stage passive work-done impeller assembly (11), while the other end is fixed with an end cap (12); one end of the shaft (5) is also equipped with a multi-stage active rotation work-done impeller assembly (10); a blast chamber (9) which is equipped with an igniter (8) is arranged between the two assemblies. The combustible gas enters the blast chamber (9) after compressed by the compressor impeller, and the high-temperature and high-pressure gas sprays from the passive work-done impeller after the ignition to drive the work-done impeller to work. The heat radiation is realized by the cold water, and the utility model solves the difficult problem that the ordinary metal material can not be made into the working impeller.
Description
The utility model relates to a kind of gas engine, belongs to a kind of gas turbine.
The advantage of gas turbine is: shockproof, nothing rubs, the efficient height, and is simple in structure, long service life, and volume is little.So people always this engine application on high-tech.Why can not widespread usage at aspects such as automobile, tractors? it mainly is the restriction that is subjected to high temperature high-pressure resistant material.The high temperature and high pressure gas that burns in the gas turbine sprays to work doing impeller, and running wheel will stand the high temperature and the 30～120 kg/cm of 2000～3000 degree always
2Pressure.So general metallic material is out of use.Gas turbine will have big development, must find a kind of material of high temperature high voltage resistant of cheapness, perhaps changes its structure, makes running wheel with ordinary metallic material, utilizes the heat radiation of self, realizes the proper functioning of motor.
The purpose of this utility model is exactly the deficiency that exists at prior art, and a kind of gas engine that adopts ordinary metallic material to make running wheel is provided.
The purpose of this utility model can realize by following measure:
A kind of gas engine is by body (6), engine shaft (5), active compression impeller (2), passive compression impeller (1), body end cap (12), multistage active rotation work doing impeller assembly (10), multistage passive work doing impeller assembly (11), two semicircle firing chambers (9), and igniter compositions such as (8): an end of body (6) is fixed multistage passive work doing impeller assembly (11), the other end is body end cap (12) fixedly, body end cap (12) is provided with suction port (3), body is cylindrical, the inboard of cylinder is assembled in multistage passive compression impeller (1), engine shaft (5) is contained in the middle of the body (6), multistage active compression impeller (2) is housed on the engine shaft (5), fastening by nut (4), one end of engine shaft (5) is equipped with multistage active rotation work doing impeller assembly (10) by key and nut, relative with multistage active rotation work doing impeller assembly (10) the multistage passive work doing impeller assembly (11) that is, in the middle of the circle of two assemblies is the firing chamber, dividing plate in the middle of multistage active rotation work doing impeller assembly (10) circle is divided into two semicircle firing chambers (9) to middle circle, igniter (8) is contained on the firing chamber, and multistage passive work doing impeller assembly (11) is provided with air inlet of combustion chamber (7).
Advantage of the present utility model:
This gas engine does not have reciprocator, so vibrations are very little.There are not the parts of friction mutually, so there is not lubrication system.Simple in structure, thermal efficiency height adopts multistage acting, can make full use of the energy of burning.Long service life, volume is little, in light weight, the employing ordinary metallic material is made running wheel and got final product proper functioning.
Description of drawings:
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is along the sectional drawing of A-A hatching among Fig. 1.
Be described in further detail by embodiment below in conjunction with accompanying drawing:
T type gas engine is made up of passive compression impeller (1), active compression impeller (2), suction port (3), nut (4), engine shaft (5), body (6), air inlet of combustion chamber (7), igniter (8), two semicircle firing chambers (9), multistage active rotation work doing impeller assembly (10), multistage passive work doing impeller assembly (11) and body end cap (12).The left end of body (6) is fixed multistage passive work doing impeller assembly (11) with screw, right-hand member is with the fixing body end cap (12) of screw, body end cap (12) is provided with suction port (3), body is cylindrical, the inboard of cylinder is assembled with multistage passive compression impeller (1), and engine shaft (5) is contained in the middle of the body (6), and multistage active compression impeller (2) is housed on the engine shaft (5), between axle and the active compression impeller (2) key is housed, and is fixed with nut.The left end of axle (5) is equipped with multistage active rotation work doing impeller assembly (10) by key and nut, relative with multistage active rotation work doing impeller assembly (10) the multistage passive work doing impeller assembly (11) that is, in the middle of the circle of two assemblies is the firing chamber, dividing plate in the middle of multistage active rotation work doing impeller assembly (10) circle is divided into two semicircle firing chambers (9) to middle circle, igniter (8) is contained on the firing chamber, and multistage passive work doing impeller assembly (11) is provided with air inlet of combustion chamber (7).
Working procedure:
Being example with gasoline: engine shaft rotates, and inflammable mixture enters motor through suction port, compression through multistage active compression impeller and passive compression impeller meets the requirements of pressure, and compressed mixed gas is when air inlet of combustion chamber opens, enter the firing chamber, air inlet of combustion chamber is closed, igniting, open the air outlet, high temperature and high pressure gas is (the passive work doing impeller of the first order) ejection from the air outlet, promotes work doing impeller work, through multistage acting, gas expands, temperature, pressure reduces, and last waste gas is discharged.
The compressed inflammable mixture that reaches certain pressure enters the firing chamber.Two firing chambers forward igniting in certain angle, acting to respectively alternately the mixed gas of certain mass.A motor secondary fire that whenever circles all is in an angle, so passive work doing impeller assembly temperature is very high, uses water-cooling, can guarantee the heat radiation of motor.Initiatively the work doing impeller assembly is two firing chamber alternations, and work doing impeller alternately is heated, does work and dispels the heat cooling.Gap work adds rotation heat radiation itself, starts the function proper functioning.
