Description
Technical field
This utility model is related to engine electric-controlled field, automatically controlled more particularly, to a kind of electric air compressor of electromotor
Device.
Background technology
At present, usually the compressed air of electromotor is provided by the mechanical air compression machine of electromotor, works as engine long
When time rotating speed is low, compressed air pressure deficiency is will result in, causes security incident.
The air motor of prior art is power source using compressed air, and the air after compression is typically stored at pressure to be held
In device, which has the disadvantage in running, and pressure is constantly reduced, and causes the output power of electromotor to be gradually lowered.However, at present
Main air compressor and original engine structure are detached, and original launch device is that one side exports power, its shortcoming
It is the waste for causing the energy.
Utility model content
The purpose of this utility model is to provide a kind of electric air compressor electric control gear of electromotor, can be electromotor
Carry out sufficient supply.
To realize that the purpose of this utility model provides a kind of electric air compressor electric control gear of electromotor, including pressure
Contracting gas tank, respectively with the tank connected electromotor of compressed gas, electric air compressor and mechanical air compression machine, on the electromotor
Speed probe is provided with, gas pressure sensor on compression gas tank, is provided with, startup is provided with electric air compressor and is connect
Tentaculum, is provided with starting contactor auxiliary contact on starting contactor, the gas pressure sensor auxiliary switch successively with turn
DC source two ends are connected in parallel on after fast sensor auxiliary switch and starting contactor series connection.
Preferably, the starting contactor auxiliary contact is connected in parallel on DC source two ends after connecting with a start indicator lamp.
Preferably, the direct current power source voltage is 12-36V.
Compared with prior art, the beneficial effects of the utility model are：
This utility model controls electric air compressor by the monitoring to air pressure in engine speed and compression gas tank
Work, efficiently solves the defect of the mechanical air compression machine for QI-insufficiency of electromotor, can carry out sufficient confession for electromotor
Gas.Especially for long-distance running vehicle, with the significant effect for strengthening travel safety.This utility model has knot simultaneously
Structure is ingenious, low cost, obvious safe effect the advantages of.
By description below and accompanying drawing is combined, this utility model will become more fully apparent, these accompanying drawings are used to explain this
The embodiment of utility model.
Description of the drawings
Fig. 1 is theory structure schematic diagram of the present utility model；
Fig. 2 is electric operation control circuit figure of the present utility model.
Specific embodiment
With reference now to Description of Drawings embodiment of the present utility model, the element numbers being similar in accompanying drawing represent similar unit
Part.
As shown in Figure 1 and Figure 2, there is provided a kind of electric air compressor electric control gear of electromotor, including compression gas tank 3,
Electromotor 4, electric air compressor 2 and the mechanical air compression machine 1 being connected with compression gas tank 3 respectively, is provided with electromotor 4
Speed probe 5, is provided with gas pressure sensor 6 on compression gas tank 3, startup contact is provided with electric air compressor 2
Device KM1, is provided with starting contactor auxiliary contact KM1-1 on starting contactor KM1, 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 source two ends.
Starting contactor auxiliary contact KM1-1 is connected in parallel on DC source two ends after connecting with start indicator lamp HL1.
Direct current power source voltage is 24V.
A kind of electric-control method of the present embodiment, the method comprise the steps：
When electromotor 4 starts, mechanical air compression machine 1 starts immediately and supplies to compression gas tank 3, when speed induction machine 5 it is real
When detect control speed induction machine auxiliary switch S2 closures when 4 rotating speed of electromotor reaches setting value, conversely, speed induction machine is auxiliary
Switch S2 is helped to disconnect；
The control baroceptor auxiliary when air pressure is less than setting value to 6 real-time detection of baroceptor in compression gas tank 3
Switch S1 closures, conversely, baroceptor auxiliary switch S1 disconnects, now because mechanical air compression machine 1 causes for QI-insufficiency
In compression gas tank 3, air pressure declines；
When speed induction machine auxiliary switch S2 and baroceptor auxiliary switch S1 are closed, starting contactor KM1 is powered
Control electric air compressor 2 starts, and Aided Machine air compressor 1 gives 3 QI invigorating of compression gas tank, conversely, starting contactor KM1
Power-off control electric air compressor 2 is closed.
Starting contactor KM1 controls starting contactor auxiliary contact KM1-1 closures after being powered make start indicator lamp HL1 bright,
It is in running order to indicate electric air compressor 2.
This utility model is described above in association with most preferred embodiment, but this utility model is not limited to the above and takes off
The embodiment shown, and the various modifications carried out according to essence of the present utility model, equivalent combinations should be covered.
