Description
Technical field
The utility model belongs to technical field of engines, particularly relates to a kind of engine start circuit.
Technical background
In the existing engineering machinery,, generally adopt starting electrical machinery to realize, adopt starting electrical machinery to realize that the startup running of motor has characteristics such as laborsaving, convenient, fast like the startup of road roller for quick ato unit.The following mode of existing employing starts: start button through the coil electricity of starting relay, drives the starting electrical machinery entry into service, and drives engine running.Unclamp start button, the coil losing electricity of starting relay, starting electrical machinery shuts down, and with the disengagement that is connected of motor, so just realized the startup of motor.Can realize the startup of motor through this Starting mode, but shortcoming is: behind the engine running, if start button is pressed in misoperation, motor will drive the starting electrical machinery running, causes starting electrical machinery to damage.Ato unit each time, motor is the running of the drive starting electrical machinery of short time all, causes the shortening in starting electrical machinery life-span.
The model utility content
To the technical problem of above-mentioned existence, the utility model provides a kind of engine start circuit.
To achieve these goals, the technological scheme of the utility model is:
The utility model comprises enable switch, generator, starting motor, starting relay, storage battery, storage battery relay, fuse box and safety relay; Said generator signal end is connected with the safety relay coil-end; The charging end of generator is connected with storage battery relay contact end; Starting relay contact input end is connected with storage battery relay contact end, and starting relay contact output terminal connects starting motor, and starting motor connects the contact output terminal of storage battery relay; The input of storage battery relay, output terminal connect fuse box respectively; The respective terminal of enable switch connects fuse box respectively, and the startup terminal of enable switch connects the starting relay coil input end, and the starting relay coil output is connected with the safety relay tip side.
Described safety relay is a normally closed relay, and described starting relay and storage battery relay are normally opened relay.
The beneficial effect of the utility model is:
The utility model is ato unit fast, prevents misoperation simultaneously, well protects starting motor, has prolonged the life-span of starting electrical machinery.
Description of drawings
Fig. 1 is the electrical block diagram of the utility model.
Among the figure: 1. enable switch, 2. storage battery relay, 3. storage battery, 4. starting relay, 5. safety relay, E. generator, E1. fuse box, M. starting motor.
Embodiment
According to accompanying drawing and embodiment the utility model is elaborated below.
Embodiment: as shown in Figure 1; The utility model comprises enable switch 1, generator E, starting motor M, starting relay 4, storage battery 3, storage battery relay 2, fuse box E1 and safety relay 5; Said generator E signal end is connected with safety relay 5 coil-end, and the charging end of generator E is connected with storage battery relay 2 tip sides, and starting relay 4 contact input ends are connected with storage battery relay 2 tip sides; Starting relay 4 contact output terminals connect starting motor M; Starting motor M connects the contact output terminal of storage battery relay 2, and the input of storage battery relay 2, output terminal connect fuse box E1 respectively, and the respective terminal of enable switch 1 connects fuse box E1 respectively; The startup terminal of enable switch 1 connects starting relay 4 coil input ends, and starting relay 4 coil outputs are connected with safety relay 5 tip sides.
The described safety relay 5 of the utility model is a normally closed relay, and described starting relay 4 is normally opened relay with storage battery relay 2.
The working principle of the utility model:
Enable switch 1 rotates to the ST shelves, behind the engine start, and generator E generating; Safety relay 5 energising excitations, safety relay 5 cuts off the grounding end of starting relay 4, at this moment; Operation start switch 1, starting relay 4 is not because of can't excitation working, and starting motor M does not turn round.Like this behind the engine running, even misoperation enable switch 1 can not make engine drives starting motor M running yet.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (2)
1. engine start circuit; It is characterized in that: comprise enable switch, generator, starting motor, starting relay, storage battery, storage battery relay, fuse box and safety relay; Said generator signal end is connected with the safety relay coil-end, and the charging end of generator is connected with storage battery relay contact end, and starting relay contact input end is connected with storage battery relay contact end; Starting relay contact output terminal connects starting motor; Starting motor connects the contact output terminal of storage battery relay, and the input of storage battery relay, output terminal connect fuse box respectively, and the respective terminal of enable switch connects fuse box respectively; The startup terminal of enable switch connects the starting relay coil input end, and the starting relay coil output is connected with the safety relay tip side.
