The device has the advantages of novel conception, simple structure, small volume, low manufacturing cost, guarantee of starting of the engine in an excellent oil lubrication state, reduction of part abrasion, prolonged service life of the engine, and capabilities of timely discovering oil lubrication faults, timely flaming out and avoiding major mechanical accidents.
Description
Technical field
The utility model belongs to motor, and relating in particular to motor does not have oil or oil pressure and cross low protection control gear.
Background technique
The motor that uses can start under the situation that does not have oil lubricating or insufficient lubrication now.Cause the wearing and tearing aggravation, working life is short.At present the engine ignitor that adopts is to be connected and composed by power supply, ignition switch, igniting actuator and warning light, rotates ignition switch, and motor moment starts.Its defective is: engine start moment, moving element often all is in running unlubricated state under in the machine, make easily parts too early, the mistake quick-wearing; Particularly when motor when running up, lubrication system breaks down suddenly, damages as explosions such as machine oil pipeline, oil filter, oil pump, the machine oil pop-off can not in time be found, more can not in time handle, cause mechanical accident easily, bring heavy economic losses.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of engine motor oil hypotony and protects control gear automatically, guarantees that motor starts under the oil pressure of setting, runs well; When breaking down suddenly, lubrication system can in time control engine stoping operation; Reduce mechanical wear, prolong motor working life.
The engine motor oil hypotony is protected control gear automatically, be to connect and compose through lead by power supply, ignition switch, flame-out actuator and machine oil warning light, be characterized in that positive source is connected with ignition switch DHK, negative pole is connected with the flame-out DJ of actuator, Oil pressure switch YLK respectively; The other end of the flame-out DJ of actuator is connected with ST retaining, the 1G retaining of ignition switch DHK through normally opened contact YSJ-1, the normally-closed contact YSJ-2 of time delay relay YSJ respectively; The other end of Oil pressure switch YLK is connected with the 1G retaining of ignition switch DHK through time delay relay YSJ coil respectively, the work of control time delay relay.
The utility model further improves, and described time delay relay YSJ establishes normally opened contact YSJ-1, and Time Delay Opening is established normally-closed contact YSJ-2, timing closing.
The utility model further improves, and the wiring base that described time delay relay YSJ establishes the band wiring terminal links into an integrated entity, and time delay relay YSJ coil, normally opened contact YSJ-1, normally-closed contact YSJ-2 are connected on the wiring terminal.
The utility model further improves, and often the opening of described time delay relay YSJ, normally-closed contact Time Delay Opening time are not more than 10 seconds, guarantees that motor is injury-free in being no more than 10 seconds scopes, and in finite time emergency shutdown, avoid accident to take place.
The utility model further improves, the described flame-out DJ of actuator, and diesel engine adopts FS-solenoid, and petrol engine adopts spark coil.
The utility model is work like this: place the 1G retaining when opening ignition switch DHK, this moment, motor did not start as yet, engine oil pressure is low excessively, Oil pressure switch YLK is in closed state, and machine oil warning light BJD lights, and time delay relay YSJ coil gets, normally opened contact YSJ-1 closure, normally-closed contact YSJ-2 opens, and disconnects the flame-out DJ of actuator circuit, and motor is in flameout state, during engine start, ignition switch DHK places the ST retaining, and the flame-out DJ of actuator is by normally opened contact YSJ-1 power supply, ato unit smoothly, make the engine motor oil lubrication system set up oil pressure, when oil pressure reached certain value, Oil pressure switch YLK opened, time delay relay YSJ coil losing electricity, its normally-closed contact YSJ-2 closure, normally opened contact YSJ-1 disconnects, and the machine oil warning light extinguishes, and motor is in normal operation.When lubrication system breaks down, Oil pressure switch YLK closure, the machine oil warning light is lighted, and disconnects the flame-out DJ of actuator circuit simultaneously, and motor is in flameout state again.
Compared with prior art, the utility model has the advantages that: novel, simple in structure, reliable; Volume is little, and cost is low, and is easy for installation, is applicable to that the engine oil pressure of new clothes allocation motivation or original motor is crossed low protection and control; Guarantee that motor normally starts under the setting engine oil pressure, lubricating status is good, alleviates the wearing and tearing of moving element greatly, prolongs the working life of motor; When turning round, high engine speeds can find in time that particularly oil lubricating is a fault, in time flame-out, and avoid great mechanical failure to take place, reduce economic loss.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is that the engine motor oil hypotony is protected the control gear electrical schematic diagram automatically.
Embodiment
As seen from Figure 1, to protect control gear automatically be to be connected and composed through lead by power supply E, ignition switch DHK, the flame-out DJ of actuator, machine oil warning light BJD and time delay relay YSJ to the engine motor oil hypotony.Power supply E is anodal to be connected with ignition switch DHK, and negative pole is connected with the flame-out DJ of actuator, Oil pressure switch YLK respectively.The other end of the flame-out DJ of actuator is connected by lead with ST retaining, the 1G retaining of ignition switch DHK through normally opened contact YSJ-1, the normally-closed contact YSJ-2 of time delay relay YSJ respectively.The other end of Oil pressure switch YLK is connected by lead with the 1G retaining of ignition switch DHK through time delay relay YSJ coil, machine oil warning light BJD respectively.
When ignition switch DHK places the 1G retaining, engine oil pressure is low excessively, Oil pressure switch YLK is in closed state, machine oil warning light BJD lights, time delay relay YSJ coil gets electric, normally opened contact YSJ-1 closure, and normally-closed contact YSJ-2 opens, disconnect the flame-out DJ of actuator circuit, motor (not marking among the figure) is in flameout state.During ato unit, ignition switch DHK places the ST retaining, and the flame-out DJ of actuator starts smoothly by normally opened contact YSJ-1 power supply, make the engine motor oil lubrication system set up oil pressure, when oil pressure reached certain value, Oil pressure switch YLK opened, time delay relay YSJ coil losing electricity, the instantaneous closure of normally-closed contact YSJ-2, normally opened contact YSJ-1 is instantaneous to be opened, and machine oil warning light BJD extinguishes, and motor is in normal operation.When oil lubricating breaks down, Oil pressure switch YLK closure, the machine oil warning light is lighted, and time delay relay YSJ gets electric, and the normally-closed contact time-delay was opened in 10 seconds, the flame-out DJ of actuator dead electricity after 10 seconds, motor quits work.
