Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and providing a kind of provides prelubricated motor pre-lubrication device in parallel to motor before engine start, to reduce the wear rate of motor.
For solving the problems of the technologies described above, the utility model comprises motor, fuel reserve tank, main lubricating oil pump, storage battery, main lubricating oil pump and motor interlock, main lubricating oil pump is communicated with engine lubrication system through fuel supply line, return tube, its structural feature is to be connected with the subsidiary engine oil pump that is driven by direct current generator on fuel reserve tank, and the oil outlet tube of subsidiary engine oil pump is connected on the fuel supply line; Engine lubrication system oil pressure upper limit of detection switch is installed on fuel supply line, and upper limit switch is a normally closed switch, the front end of upper limit switch through the motor electric switch be electrically connected with storage battery, the rear end is electrically connected with the subsidiary engine oil pump,
On the circuit between upper limit switch and the electric switch, be provided with subsidiary engine pump start switch.
On the circuit between upper limit switch and the subsidiary engine oil pump, be provided with subsidiary engine oil pump work indicator light.
The engine lubrication system oil pressure also is installed on fuel supply line detects limit switch, limit switch is normally closed switch and is electrically connected with storage battery through the motor electric switch, be serially connected with the low pressure alarming tutorial light on this circuit.
After adopting said structure; the utility model is on the basis of original lubricating fitting; a subsidiary engine oil pump in parallel provides pre-lubrication for motor before engine start; reduce the wear rate of motor, increased the tightness of motor simultaneously, solved the startup difficulty that motor lowly causes because of tightness; thoroughly get rid of motor and damaged seize, the card cylinder phenomenon that causes because of former lubrication system; effectively protect motor, prolonged the working life of motor, and simple in structure, easy for installation.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
With reference to accompanying drawing, this motor pre-lubrication device in parallel comprises motor 1, fuel reserve tank 4, main lubricating oil pump 2, storage battery 6, main lubricating oil pump 2 is driven by motor 1, be provided with fuel supply line 12 between main lubricating oil pump 2 and the motor 1, be provided with return tube 13 between motor 1 and the fuel reserve tank 4, be provided with fuel sucking pipe 10 between main lubricating oil pump 2 and the fuel reserve tank 4, main lubricating oil pump 2, fuel supply line 12, return tube 13 and fuel reserve tank 4 constitute the former lubrication system of motor.Be connected with the subsidiary engine oil pump 3 that is driven by direct current generator 5 on fuel reserve tank 4, the oil outlet tube 11 of subsidiary engine oil pump 3 is connected on the fuel supply line 12, is provided with fuel sucking pipe 9 between subsidiary engine oil pump 3 and the fuel tank 4; Engine lubrication system oil pressure upper limit of detection switch 8 is installed on fuel supply line 12, upper limit switch 8 is a normally closed switch, the front end of upper limit switch 8 through motor electric switch 17 be electrically connected with storage battery 6, the rear end is electrically connected with subsidiary engine oil pump 3, be provided with subsidiary engine pump start switch 7 on the circuit between upper limit switch 8 and the electric switch 17, the circuit between upper limit switch 8 and the subsidiary engine oil pump 3 is provided with subsidiary engine oil pump work indicator light 14.The engine lubrication system oil pressure also is installed on fuel supply line 12 detects limit switch 16, limit switch 16 is normally closed switch and is electrically connected with storage battery 6 through motor electric switch 17, be serially connected with low pressure alarming tutorial light 15 on this circuit.
Working principle of the present utility model is: when engine start front opening motor electric switch 17, connect general power, press subsidiary engine pump start switch 7, this moment, storage battery 6 began to be direct current generator 5 power supplies, direct current generator 5 drives 3 work of subsidiary engine oil pump, subsidiary engine oil pump 3 provides pre-lubrication by fuel supply line 12 for motor 1, and this moment, main lubricating oil pump 2 played by motor 1 through the effect to fuel reserve tank 4 oil circuits of fuel supply line 12, fuel sucking pipe 10.When lubrication system reaches clean boot pressure, limit switch 16 disconnects, alarm indicator lamp 15 extinguishes, by motor electric switch 17 ato units 1, drive main lubricating oil pump 2 by motor 1 and provide lubricated for motor, this moment is owing to main lubricating oil pump 2, subsidiary engine oil pump 3 are engine oil simultaneously, oil pressure surpasses safety value, upper limit switch 8 disconnects, and subsidiary engine oil pump 3 quits work, and system runs well.When main oil supply system breaks down, the engine lubrication system oil pressure reduces, when oil pressure is lower than safety value, and upper limit switch 8 closures, direct current generator 5 drives 3 work of subsidiary engine oil pumps, for motor provides lubricated.
