Abstract
The utility model discloses a small diesel engine fuel injection pump with an air exhausting function. The small diesel engine fuel injection pump with the air exhausting function comprises an oil tank and an oil pump. An oil inlet and an oil outlet are arranged on the oil pump, the oil tank is connected with the oil inlet of the oil pump through an oil pipeline, an air exhausting opening is further arranged on the oil pump, the oil tank is connected with the air exhausting opening of the oil pump through an air exhaust pipe, and the height of the bottom of the oil tank is higher than that of the oil inlet or the air exhausting opening of the oil pump. According to the structure, due to the fact that the air exhausting opening is arranged on the oil pump, when air exists in the oil pipeline, the air is discharged to the oil tank by the air exhausting opening of the oil pump through the air exhaust pipe, and the air is further discharged by an air exhausting opening of the oil tank, and therefore a fuel filter with an air exhausting function does not need to be arranged in the oil pipeline, and even the fuel filter is arranged, mounting position of the fuel filter does not need to be considered. Meanwhile, even the air exists in the oil pipeline, the oil pipeline does not need to be demounted to discharge the air, two ends of the oil pipeline can be connected with the oil tank and the oil pump, and therefore, leakage of fuel oil is reduced, and operation difficulty is reduced.
Description
Technical field
The utility model relates to the power plant of small diesel engine, relates in particular to the small diesel engine Injection Pump of the band degassing function in the power plant of small diesel engine.
Background technique
At present, small diesel engine all is to utilize the blast acting of Piston Compression diesel oil air gas mixture, the diesel oil in the fuel tank through transport pipe through fuel filter or directly insert the filler opening of oil pump.Wherein, the effect of oil pump is the fuel oil to power supply capacity regularly.If before the dynamic start, there is air in the transport pipe, power just can't normally start, and must extract the transport pipe of oil pump, bleeds off diesel oil in a small amount, guarantees the residual filler opening that turns back to oil pump again of no air in the transport pipe.Even the fuel filter that has degassing function in the transport pipe also can't the emptying fuel filter and oil pump between oil pipe in air.So the structure of no special eliminating transport pipe air between existing fuel tank and oil pump, when having air in the transport pipe, not only dynamic start trouble, and waste diesel oil.
Summary of the invention
The purpose of the utility model provides a kind of small diesel engine Injection Pump of the band degassing function of can be easily the air in the transport pipe being got rid of.
For realizing above-mentioned purpose; The small diesel engine Injection Pump of the utility model band degassing function comprises fuel tank and oil pump, and oil pump is provided with filler opening and oil outlet; Fuel tank is connected with the filler opening of oil pump by transport pipe; Also be provided with relief opening on the said oil pump, fuel tank is connected with the relief opening of oil pump by outlet pipe, and the fuel tank bottom level is higher than the filler opening of oil pump and the height of relief opening.
The pipeline road of said fuel tank and oil pump is provided with fuel filter.
Adopt the structure of the utility model; Oil pump is provided with relief opening, and when having air in the transport pipe, air is discharged in the fuel tank through outlet pipe by the relief opening of oil pump; Discharge by the relief opening of fuel tank again; The fuel filter of band degassing function need be set in the transport pipe,, need not to consider the mounting point of fuel filter yet even fuel filter is set; Simultaneously,, need not remove transport pipe emptying gas, can the transport pipe two ends firmly be connected with oil pump with fuel tank respectively, reduce the water clock of fuel oil, reduce operation easier even there is air in the transport pipe.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the small diesel engine Injection Pump of the utility model band degassing function;
Fig. 2 is the structural representation of the small diesel engine Injection Pump of the utility model band fuel filter.
Embodiment
Like Fig. 1 or shown in Figure 2; The small diesel engine Injection Pump of the utility model band degassing function comprises fuel tank 1 and oil pump 2, and oil pump 2 is provided with filler opening 21 and oil outlet 22; Fuel tank 1 is connected with the filler opening 21 of oil pump 2 by transport pipe 3; Also be provided with relief opening 23 on the said oil pump 2, fuel tank 1 is connected with the relief opening 23 of oil pump 2 by outlet pipe 4, and fuel tank 1 bottom level is higher than the filler opening 21 of oil pump 2 and the height of relief opening 23.
Because oil pump 2 is provided with relief opening 23, when having air in the transport pipe 3, air and oil get in the oil pump 2 simultaneously, and air is discharged in the fuel tank 1 through outlet pipe 4 by the relief opening 23 of oil pump 2, is drained by the relief opening of fuel tank 1 again.The fuel filter 5 of band degassing function need be set in the transport pipe 3; Simultaneously,, can drain, need not remove transport pipe 3 emptying gas, can transport pipe 3 two ends firmly be connected with oil pump 2 with fuel tank 1 respectively, reduce the water clock of fuel oil, reduce operation easier by the relief opening 23 of oil pump 2 even have air in the transport pipe 3.
Said fuel tank 1 is provided with fuel filter 5 with the pipeline road of oil pump 2; Need not consider the mounting point of fuel filter 5; As long as fuel tank 1 bottom level is higher than the filler opening 21 of oil pump 2 and the height of relief opening 23, then the air in the transport pipe 3 can be drained by the relief opening 23 of oil pump 2 smoothly.
Claims (2)
1. be with the small diesel engine Injection Pump of degassing function; Comprise fuel tank and oil pump; Oil pump is provided with filler opening and oil outlet, and fuel tank is connected with the filler opening of oil pump by transport pipe, it is characterized in that: also be provided with relief opening on the said oil pump; Fuel tank is connected with the relief opening of oil pump by outlet pipe, and the fuel tank bottom level is higher than the filler opening of oil pump and the height of relief opening.
2. the small diesel engine Injection Pump of band degassing function according to claim 1 is characterized in that: the pipeline road of said fuel tank and oil pump is provided with fuel filter.
