In described main oil gallery, safety check is installed, described oil storage cylinder is connected to the top of safety check.
Compared with prior art the utlity model has following advantage: in diesel engine operation process, electromagnetic lock does not start, machine oil enters oil storage cylinder and promotes piston from oil inlet pipe and moves backward, spring-compressed, air in piston rear cavity is discharged by relief opening, when the locked groove on piston aligns with lock pin, lock pin falls completely, insert in locked groove and piston is located, while closed electromagnetic valve, now the cavity of oil storage cylinder inner carrier front portion is full of machine oil, during oil start energising, signal is passed to electromagnetic lock, the magnetic-adsorption lock pin that electromagnetic lock produces makes its rising, solenoid valve is opened simultaneously, spring reset now, and promote piston forward and move, machine oil in oil storage cylinder is injected to main oil gallery, realization is to diesel engine pre-lubrication, engine oil pressure when the utility model utilizes diesel engine running in main oil gallery carries out energy storage, then diesel engine is carried out to pre-lubrication when starting, high lubricating effect, and the complicated loaded down with trivial details installation pipeline of cancellation, simple in structure, and can be by spring force and the adjustment of oil cylinder volume being met to the needs of different diesel engines, highly versatile.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is the phase diagram of the utility model when oil-filled;
Fig. 2 is the phase diagram of the utility model while draining the oil;
Fig. 3 is the annexation figure of oil storage cylinder and main oil gallery.
Embodiment
With reference to accompanying drawing, this diesel engine starting pre-lubrication device comprises the oil storage cylinder 3 being connected with main oil gallery 9, in Fig. 3, A direction is direction of engine oil flow in main oil gallery 9, safety check 8 is installed in main oil gallery 9, oil storage cylinder 3 is connected to the top of safety check 8, while preventing from starting, the machine oil that pre-lubrication device discharges flows back to oil sump from oil pump.Between the front end of oil storage cylinder 3 and main oil gallery 9, be connected with oil inlet pipe 1, solenoid valve 2 is installed on oil inlet pipe 1, the interior sealing of oil storage cylinder 3 slidably connects piston 6, the front portion of piston 6 is shoe cream room, between piston 6 and oil storage cylinder 3 rearward end, spring 7 is installed, the rear portion of oil storage cylinder 3 is provided with the relief opening 5 being communicated with its cavity, when piston 6 moves backward, air in oil storage cylinder 3 rear cavity is discharged from relief opening 5, between oil storage cylinder 3 and piston 6, Locking Device is installed.In the present embodiment, Locking Device comprises the electromagnetic lock 4 that is arranged on oil storage cylinder 3 tops and is connected with diesel engine electric, and electromagnetic lock 4 is electrically connected to solenoid valve 2.The bottom of electromagnetic lock 4 is provided with lock pin 41, and lock pin 41 relies on self gravitation sagging, and when electromagnetic lock 4 does not start, lock pin 41 is for falling state or be whereabouts trend, and the outer wall of oil storage cylinder 3 is provided with through hole, and lock pin 41 stretches in the inner chamber of oil storage cylinder 3 through through hole.The front end of piston 6 is equipped with the locked groove corresponding with lock pin 41 31, and locked groove 31 can hold lock pin 41.Oil storage cylinder 3 rear inside wall are provided with the clamping section 32 of stretching out forward, spring 7 one ends are sleeved in clamping section 32, piston 6 rear portions are hollow structure, in its inner chamber, be provided with and stretch out backward and the second clamping section 62 corresponding with the first clamping section 32, the other end of spring 7 is sleeved in the second clamping section 62, thus the location of realizing spring 7.
