Description

General generator unit

Technical field

The utility model relates to a kind of general generator unit, belongs to the power plant field.

Background technique

In traditional generator, canister is positioned in the inside of fuel tank cap usually, to be used for absorbing the gasoline vapor that evaporates from fuel tank, gasoline vapor is absorbed in the jar and imports a suction system that links to each other with the generator main body, because canister is arranged on the inside of fuel tank cap, causes the unreasonable change in this position big.And general generator claimed structure compactness, so that working portion is unlikely to excessive.Therefore, how under the prerequisite of the size that does not increase body, gasoline vapor and waste gas to be handled,, become a urgent problem to reach environmental requirement.

The model utility content

For addressing the above problem, the purpose of this utility model is to provide a kind of environment protection type general purpose engine unit, and this general generator unit has been installed canister under the prerequisite that does not increase cabinet size.

The technological scheme that the utility model is taked is: a kind of general generator unit, include frame, fuel tank and motor are installed in the frame, the main body of motor comprises that a crankcase and one are connected in the cylinder block that makes progress at an angle with crankcase on the crankcase, suction system and vent systems are installed in the both sides of cylinder block, suction system is mainly by empty filter, Carburetor is formed, vent systems is mainly by the silencing apparatus bend pipe, silencing apparatus, outlet pipe is formed, clear position below cylinder block is equipped with canister, canister is installed in a side of crankcase by the canister support, canister one end links to each other with fuel vapour passage in the fuel tank by gas production valve flexible pipe, link to each other with empty filter by empty filter flexible pipe, link to each other with heat insulation flange by heat insulation flange flexible pipe, and the suction system that links to each other with the generator main body of importing, silencing apparatus links to each other with suction system by the silencing apparatus bend pipe, be filled with catalyzer at silencing apparatus bend pipe and silencing apparatus joint, on the silencing apparatus bend pipe, also be connected with secondary air-supplementing valve by the aeration valve bend pipe.

The beneficial effects of the utility model are: 1, because canister is placed in the clear position of the below of cylinder block, and an inclination angle that makes progress is arranged, so the arrangement of canister does not increase the external dimension of motor.And because heat insulation flange flexible pipe and gas production valve flexible pipe are connected canister gas handling system one side, the used heat that body produces is very little to its influence, and used heat can not influence the absorption and the desorption process of canister, has therefore increased the efficient of canister.2, secondary air-supplementing valve and catalyzer under the situation of the size that does not increase the generator unit, have been added, on the exhaust outlet of combustion chamber of cylinder block and the silencing apparatus bend pipe between the silencing apparatus, increase an aeration valve bend pipe and secondary air-supplementing valve, this secondary air-supplementing valve is an one-way valve, when the silencing apparatus exhaust, inhale fresh air, under the effect of catalyzer, make the waste gas secondary combustion.Thereby reach higher discharge-ring guaranteed request.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment

The 10-frame, the 11-fuel tank cap, the 12-fuel tank, 13-gas production valve, the 14-oil level monitor, 15-oil pipe clip, 16-gas production valve flexible pipe, the heat insulation flange of 17-, the 18-Carburetor, the heat insulation flange flexible pipe of 19-, the empty filter flexible pipe of 20-, the empty filter of 21-, the 22-motor, the 23-canister, 24-canister support, the 25-secondary air-supplementing valve, 26-aeration valve bend pipe, 27-silencing apparatus bend pipe, the 28-catalyzer, the 29-buffer stopper, the 30-motor, the 31-outlet pipe, the 32-silencing apparatus, 33-gas production valve output tube, 34-canister support, the 35-cylinder block, the 36-crankcase, the 37-suction system, the 38-vent systems, 39-gasoline

As Fig. 1, shown in Figure 2, the utility model includes frame 10, fuel tank 12 and motor 22 are installed in the frame 10, the main body of motor 22 comprises that a crankcase 36 and one are connected in the cylinder block 35 that makes progress at an angle with crankcase 36 on the crankcase 36, suction system 37 and vent systems 38 are installed in the both sides of cylinder block 35, suction system 37 is mainly by empty filter 21, Carburetor 18 is formed, vent systems is mainly by silencing apparatus bend pipe 27, silencing apparatus 32, outlet pipe 31 is formed, clear position below cylinder block 35 is equipped with canister 23, canister 23 is installed in a side of crankcase 36 by canister support 24, canister 23 1 ends link to each other by the fuel vapour passage in gas production valve flexible pipe 16 and the fuel tank 12, link to each other with empty filter 21 by empty filter flexible pipe 20, link to each other with heat insulation flange 17 by heat insulation flange flexible pipe 19, and the suction system 37 that links to each other with the generator main body of importing, vent systems 38 comprises the silencing apparatus 32 that links to each other with suction system 37 by silencing apparatus bend pipe 27, be filled with catalyzer 28 at silencing apparatus bend pipe 27 and silencing apparatus 32 joints, on silencing apparatus bend pipe 27, also be connected with secondary air-supplementing valve 25 by aeration valve bend pipe 26.

Working principle of the present utility model is: the gasoline vapor in the fuel tank 12 is absorbed in the canister 23 by gas production valve 13 and gas production valve flexible pipe 16, and be transferred to the suction system 37 that importing links to each other with the generator main body in the heat insulation flange 17 by heat insulation flange flexible pipe 19, after vent systems 38 is discharged, canister 23 passes to mutually with atmosphere by the empty filter 21 of empty filter flexible pipe 20 connections and reaches pressure balance through combustion disposal.When generator is under the shut down condition, the gasoline vapor that fuel tank 12 volatilizations produce makes the fuel tank 12 inner malleations that produce, the part gasoline vapor arrives canister 23 by the gas production valve flexible pipe 16 at fuel tank 12 tops, active carbon adsorption gasoline vapor by 23 li of canisters, under generator is in running order, because gasoline consumption, the fuel tank 12 inner negative pressure that produce, by empty filter 21 supplementary airs that link to each other with canister 23, also can make fuel tank 12 pressure inside be unlikely to be negative value, therefore, though the fuel oil in the oil level decline fuel tank 12 also can supply with smoothly.

The beneficial effects of the utility model are: 1, because canister 23 is placed in the clear position of the below of cylinder block 35, and an inclination angle that makes progress is arranged, so the arrangement of canister 23 does not increase the external dimension of motor 22.And because heat insulation flange flexible pipe 19 and gas production valve flexible pipe 16 are connected canister 23 gas handling systems one side, the used heat that body produces is very little to its influence, and used heat can not influence the absorption and the desorption process of canister 23, has therefore increased the efficient of canister 23.2, secondary air-supplementing valve 25 and catalyzer 28 under the situation of the size that does not increase generator, have been added, on the exhaust outlet of combustion chamber of cylinder block 35 and the silencing apparatus bend pipe 27 between the silencing apparatus 32, increase an aeration valve bend pipe 26 and secondary air-supplementing valve 25, this secondary air-supplementing valve 25 is an one-way valve, when silencing apparatus 32 exhausts, inhale fresh air, under the effect of catalyzer, make the waste gas secondary combustion.Thereby reach higher discharge-ring guaranteed request.
