The utility model will have the electric starting device and the electronic pre-oil feed pump that are installed on the high-power diesel engine now and be combined as a whole, only can successively realize supplying in advance machine oil and start-up function with a motor, not only reduced by a motor, other component such as solenoid valve in the control circuit have been saved, reduced manufacture cost, and saved installing space, and be convenient to the global design of machine, make diesel engine compact more attractive in appearance.The utility model only need be pressed switch starter, could start diesel engine after can guaranteeing earlier each lubricating point in the diesel engine to be lubricated for machine oil in advance, avoid misoperation of users, guaranteed the correct Security of diesel engine starting operation, reduced the rate of fault of diesel engine.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
The accompanying drawing illustrated embodiment the utlity model has one by the direct current motor 15 of 24V storage battery 18 as power supply.Be movably installed with actuation gear 14 at direct current motor 15 armature shaft right-hand members by axle sleeve, actuation gear 14 can left and right sides slippage on armature shaft, when it outwards shifts out, can mesh fully, drive its rotation to realize diesel engine starting by motor 15 with the flywheel ring gear of diesel engine.The other end at this direct current motor 15 is installed with the oil pump 16 that is connected with armature shaft, drives its work by motor 15 and realizes that prestart supplies machine oil in advance to each lubricating point in the diesel engine.The magnetic switch 17 that is electrically connected with it is installed on the top of direct current motor 15.Magnetic switch 17 comprises housing and is installed in the interior brass sleeve 8 of housing, and secured core 9 and movable core 12 are installed in brass sleeve 8, corresponding to secured core 9 and movable core 12 sucking coil 10 and the hold-in winding 11 that is wrapped in brass sleeve 8 outsides is arranged.Be connected with pull bar 19 on the movable core 12, the end of pull bar 19 is connected with shift fork 13 upper ends that are hinged on the body by hinge, and actuation gear 14 axial outer moving can be stirred in the lower end of shift fork 13.Slide bar 20 is housed in the axial hole of secured core 9, and secured core 9 is stretched out at slide bar 20 two ends, and its outer end is fixed with the contact disc 7 that can conduct electricity.The wiring terminal 4 and the wiring terminal 5 that wiring terminal 6 are installed on switch shell of Electromagnetic and can be electrically connected respectively with contact disc 7, the two ends of sucking coil 10 are connected with wiring terminal 4 with wiring terminal 6 respectively, and an end of hold-in winding 11 is connected with wiring terminal 6, the other end ground connection.Wiring terminal 4 is connected with direct current motor 15.Wiring terminal 6 and wiring terminal 5 also are electrically connected with an end of a time relay 3, the other end of the time relay 3 is electrically connected with a normally opened contact by the pressure relay 2 of engine oil pressure control, and the normally-closed contact of pressure relay 2 is electrically connected with direct current motor 15.Switch starter 1 is connected between pressure relay 2 and the storage battery 18 as DC electrical source.In order to promote contact disc 7 better, the secured core 9 of magnetic switch 17 and the mating face of movable core 12 have projection and the groove that cooperatively interacts, and promptly the inner of secured core 9 is a conical protrusions, and the inner of movable core 12 is a cone-shaped groove.
Working principle of the present utility model is:
Press switch starter 1, because pressure relay 2 is in normally off when the diesel engine oil pressure is lower than its setting value, this moment, circuit formed closure, electric current can directly drive direct current motor 15 rotations, the armature shaft of direct current motor 15 directly drives oil pump 16 work, and each lubricating point in the diesel engine is supplied machine oil in advance.This moment since the normally opened contact of the time relay 3 pressure relayes 2 connect, i.e. magnetic switch 17 no electric circuits, shift fork 13 can not be transferred to actuation gear 14, actuation gear 14 dallies in position, can not drive diesel engine starting.
Oil pump is after 16 work a period of times, and the diesel engine oil pressure promptly reaches the setting numerical value of pressure relay 2, and this moment, pressure relay 2 was transformed on the normally opened contact.If for guarantee not allow actuation gear 14 in rotation, enter into the flywheel ring gear neutralization avoid direct current motor 15 to work long hours and occur overheated, utilize the time relay 3 time-delay certain hours, after actuation gear 14 stops the rotation, the main contact of the time relay 3 is connected, connect the circuit of magnetic switch 17, the circuit that is sucking coil 10 and hold-in winding 11 is connected, secured core 9 is with movable core 12 adhesives, movable core 12 is outwards transferred to actuation gear 14 by pull bar 19 pulling shift forks 13 when left movement, when the flywheel ring gear of actuation gear 14 and diesel engine enters engagement fully, movable core 12 is released contact disc 7 left by slide bar 20, contact disc 7 is connected wiring terminal 4 and wiring terminal 5, being about to direct current motor 15 connects with storage battery 18, direct current motor 15 begins to rotate, its overrunning clutch fuses actuation gear 14 and armature shaft, drives the flywheel rotation and makes diesel engine starting.
Behind the proceed-to-send, unclamp switch starter 1, this moment circuitry cuts, motor quits work, the time relay 3 is because the outage of its control wiring also can disconnect, magnetic switch 17 is recovered original states.After diesel engine stopped, engine oil pressure was lower than the setting value of pressure relay 2, and this moment, pressure relay 2 was got back to normally off again, at first carried out when starting ready for machine oil in advance next time.
