Description
Technical field
The present invention relates to engine electric-controlled fields, more particularly, to a kind of automatically controlled dress of the electric air compressor of engine
It sets, the invention further relates to a kind of electric air compressor electric-control methods of engine.
Background technology
Currently, usually the compressed air of engine is provided by the mechanical air compression machine of engine, work as engine long
When time rotating speed is low, compressed air pressure deficiency is will result in, safety accident is caused.
The air motor of the prior art is power source using compressed air, and compressed air is typically stored at pressure appearance
In device, the disadvantage is that in the process of running, pressure constantly reduces, the output power of engine is caused to continuously decrease.However, at present
Main air compressor and original engine structure are separation, and original launch device is one side output power, disadvantage
It is the waste for causing the energy.
Invention content
The purpose of the present invention one is to provide a kind of electric air compressor electric control gear of engine, can be engine into
The sufficient gas supply of row.
The purpose of the present invention two is to provide a kind of method for realizing above-mentioned electric control gear.
One provide a kind of electric air compressor electric control gear of engine, including compression to achieve the purpose of the present invention
Gas tank is set respectively with the tank connected engine of compressed gas, electric air compressor and mechanical air compression machine on the engine
It is equipped with speed probe, gas pressure sensor is provided on compression gas tank, startup contact is provided on electric air compressor
Device, is provided with starting contactor auxiliary contact on starting contactor, the gas pressure sensor auxiliary switch successively with rotating speed
It is connected in parallel on DC power supply both ends after sensor auxiliary switch and starting contactor series connection.
Preferably, the starting contactor auxiliary contact is connected in parallel on DC power supply both ends after connecting with a start indicator lamp.
Preferably, the direct current power source voltage is 12-36V.
Two provide a kind of electric air compressor electric-control method of engine, this method packet to achieve the purpose of the present invention
Include following steps,
When engine start, mechanical air compression machine starts immediately to be supplied to compression gas tank, when speed induction machine is examined in real time
It measures speed induction machine auxiliary switch when engine speed reaches setting value to be closed, conversely, speed induction machine auxiliary switch disconnects；
When baroceptor detects that air pressure is less than setting value in compression gas tank in real time, baroceptor auxiliary switch closes
It closes, conversely, baroceptor auxiliary switch disconnects；
When speed induction machine auxiliary switch and baroceptor auxiliary switch are all closed, starting contactor power control is electronic
Air compressor starts, and mechanical air compressor is assisted to give compression gas tank tonifying Qi, conversely, starting contactor power-off controls electronic sky
Air compressor is closed.
Preferably, control starting contactor auxiliary contact closure keeps start indicator lamp bright after the starting contactor is powered.
Compared with prior art, the beneficial effects of the present invention are：
The present invention controls electric air compressor work by the monitoring to air pressure in engine speed and compression gas tank,
The mechanical air compression machine for efficiently solving engine supplies insufficient defect, can be that engine carries out sufficient gas supply.It is special
It is not to have the function of significantly enhancing travel safety for long-distance running vehicle.Simultaneously the present invention have clever structure, at
The advantages that this is low, safe effect is apparent.
By description below and in conjunction with attached drawing, the present invention will become more fully apparent, these attached drawings are for explaining the present invention
Embodiment.
Description of the drawings
Fig. 1 is the principle of the present invention structural schematic diagram；
Fig. 2 is the electric operation control circuit figure of the present invention.
Specific implementation mode
The embodiment of the present invention described referring now to the drawings, similar element numbers represent similar element in attached drawing.
As shown in Figure 1 and Figure 2, a kind of electric air compressor electric control gear of engine, including compression gas tank 3 are provided,
Engine 4, electric air compressor 2 and the mechanical air compression machine 1 being connect respectively with compression gas tank 3 are provided on engine 4
Speed probe 5 is provided with gas pressure sensor 6 on compression gas tank 3, and startup contact is provided on electric air compressor 2
Be provided on device KM1, starting contactor KM1 starting contactor auxiliary contact KM1-1, gas pressure sensor auxiliary switch S1 according to
It is secondary connect with speed probe auxiliary switch S2 and starting contactor KM1 after be connected in parallel on DC power supply both ends.
Starting contactor auxiliary contact KM1-1 is connected in parallel on DC power supply both ends after connecting with start indicator lamp HL1.
Direct current power source voltage is 24V.
The present invention also provides a kind of electric air compressor electric-control methods of engine, and this method comprises the following steps：
When engine 4 starts, mechanical air compression machine 1 starts immediately to be supplied to compression gas tank 3, when speed induction machine 5 is real
When detect that speed induction machine auxiliary switch S2 is controlled when 4 rotating speed of engine reaches setting value to be closed, conversely, speed induction machine is auxiliary
Switch S2 is helped to disconnect；
The control baroceptor auxiliary when baroceptor 6 detects that air pressure is less than setting value in compression gas tank 3 in real time
Switch S1 is closed, conversely, baroceptor auxiliary switch S1 is disconnected, at this time because mechanical air compression machine 1 causes for unsaturated vapor
Air pressure declines in compression gas tank 3；
When speed induction machine auxiliary switch S2 and baroceptor auxiliary switch S1 are closed, starting contactor KM1 is powered
