Description
Technical field
The utility model is related to a kind of high-power engine starter, more particularly to a kind of high-power engine gas motor
Starter.
Background technology
The engine ability without self start in itself, is substantially compressed air starting.The power of engine is bigger, right
The starting reactance answered is just big.Existing high-power, large-diameter engine, start mode such as Fig. 1；Compression from air bottle is empty
Gas, while into firing switch 14 and main starting valve 13, compressed air enters main starting valve when pressing firing switch, pushes away work
Plug is descending, opens main starting valve.When main starting valve is opened, compressed air point two-way；All the way through check valve 15 and cylinder head
Path enters priming valve 16, and then another road air inlet distributor 12 promotes piston acting.This Starting mode need to use equipment
Cumbersome, it is long to start the time, and start it is unstable, while because causing equipment part maintenance cost high more.So as to develop
A kind of high-power engine starter.
On the other hand, although air motor possess can with stepless speed regulation work safety, have overload protective function, will not be because of mistake
Carry and break down, with higher starting torque many advantages, such as, but it can produce larger noise when in use, to work
Environment has adverse effect on.
The content of the invention
The purpose of this utility model is to solve to directly initiate high-power engine startup time length in the prior art, needs to use
The drawbacks of part is more and work when the big technical problem of noise, further solve motor gear it is easy to wear, service life is short to ask
Topic.
To achieve these goals, the technical solution of the utility model is as follows,
A kind of high-power engine gas motor starting device, including filter, pressure-reducing valve, main starting valve, air motor, electricity
Magnet valve, motor support and flywheel ring gear；Filter, pressure-reducing valve, main starting valve, air motor, magnetic valve connect successively from left to right
Connect, motor support is arranged on chassis, air motor is installed on top, flywheel ring gear is engaged with motor gear, solenoid valve control master
Priming valve is opened.Starting pinciple is that the source of the gas that is come out from air compressor is adjusted to system by pressure-reducing valve and needs to enter after pressure
Main starting valve, main starting valve first urges starter motor action, and motor gear is engaged with flywheel ring gear, solenoid valve control main starting valve
Open, starter motor quickly rotates, flywheel driven gear ring high-speed rotation, pusher cylinder completes acting.
As a kind of improvement of the present utility model, what the gas motor starting device was also connected including one with air motor
Noise-reducing structure, noise-reducing structure includes the sleeve pipe and the porous S types bend pipe in sleeve pipe of a upper and lower side closing, and internal surface of sleeve pipe has
Sound-absorbing material.Air is flowed into from porous S types bend pipe one end, and outflow aperture flows out after casing wall multiple reflections from the other end, rises
To the effect of noise reduction.
As a kind of improvement of the present utility model, one layer of wear-resistant paint chromium nitride is scribbled outside the gas electric motors gear,
Further extend the service life of gas motor starting device.
Relative to prior art, advantage of the present utility model is as follows,
The gas motor starting device startup time is short, and startup is reliable and stable, is influenceed small by site environment and temperature, Yi Bao
Support and safeguard that service life is long, and work noise is small；It is changed to after the starting of gas motor, the part such as air distributor, air hose no longer makes
With engine structure simplifies, many advantages, such as reducing cost, reduction fault rate, and being mainly used in high-power engine needs startup
Moment of torsion is big, starts the short occasion of time requirement.
