Description

A kind of air-fuel mixture starter
Technical field
The present invention relates to engine primer technical fields, and in particular to a kind of oil gas for Micro Turbine Jet Engine is mixed Close starter.
Background technique
Because Micro Turbine Jet Engine voluntarily cannot be transferred to working condition by static, it is necessary to use external force turning crankshaft, Zhi Daoqu Axis reaches engine and starts the necessary revolving speed that burns, and guarantees that the formation, compression and igniting of gaseous mixture can be gone on smoothly.Start Machine claims the starting of engine by the static overall process for being transferred to working condition.A series of dresses needed for completing engine starting process Set title engine starting gear.
Current almost all of automobile engine all uses electric starter motor to start.When on motor reel driving gear with When ring tooth engagement on engine flywheel periphery, the electromagnetic torque that motor generates when rotating passes to engine by flywheel Crankshaft makes engine start.Electric starter motor abbreviation starter., using battery as power supply, structure is simple and convenient to operate, rises for it It is dynamic reliable rapidly.
China Patent No. " CN106882393A " discloses unmanned vehicle engine starter.The invention proposes unmanned planes The head of unmanned plane, including engine spindle is arranged in engine starting gear, engine, and axle sleeve fixed plate is fixed at hair The outer of motivation main shaft is put on, and starting motor is fixed in axle sleeve fixed plate, including motor and gear；Duplicate gear fixation is set It sets in axle sleeve fixed plate, including bull wheel and steamboat, the bull wheel in duplicate gear is engaged with the gear in starting motor；Engine Nested spiral positioning column, ratchet are nested on spiral positioning column, engage with the steamboat in duplicate gear on main shaft；Engine Propeller hub is arranged in the end of main shaft, and propeller is arranged on propeller hub, and the entire ignition process duration is shorter and easy to use, energy consumption It is less, it is a kind of fairly simple practical sparking mode, but equally only supports a kind of sparking mode.
Micro turbine engine Starting mode in the prior art is that combustion gas starting or fuel oil start, combustion gas Starting mode fire Head workload is high, is easily damaged, and igniting has some setbacks when ambient wind velocity is very fast；Fuel oil Starting mode, preheating time is long, and starting is slow Slowly, fuel slippage reduces under low temperature environment, and ignition failure rate is high.
Summary of the invention
It is a kind of for the non-contact of Micro Turbine Jet Engine it is an object of the invention to avoid the deficiencies in the prior art from providing Formula electromagnetic clutch, to solve problems of the prior art.
To achieve the above object, the technical scheme adopted by the invention is as follows：A kind of air-fuel mixture starter, it is special Point be include the working connection conduit and gas conduct pipe being arranged on engine charge lid and diffuser, working connection conduit and combustion gas are led Pipe is connected with fuel distribution disk, multiple working connection oil pipes and tracheae is provided on fuel distribution disk, working connection oil pipe and tracheae are stretched Enter and burn in indoor evaporation tube, igniter head is mounted on combustion chamber end by fuel distribution disk correspondence, and igniter head passes through igniting Oil pipe is connected with igniting oil circuit conduit, and the combustion chamber is mounted on air deflector, and air deflector is mounted on heat-insulated on bearing holder (housing, cover) It puts on.
The working connection conduit is connected by fuel distribution disk with multiple working connection oil pipes, and gas conduct pipe passes through fuel oil point It is connected with disk with multiple tracheaes, is additionally provided with shell outside the combustion chamber.
The beneficial effects of the invention are as follows：A kind of air-fuel mixture starter, uses both-initiated strategy mode, starts Machine preheating is fast, and Acceleration of starting is fast；Stable and reliable in work using fuel oil igniter head, the service life is long；It is simple and reliable for structure, extreme environment Under it is adaptable.
