Abstract
The utility model relates to the horizontal rifle of a kind of diesel engine oil supply system high pressure, formed by fuel duct, gap filter cleaner, orifice valve, it is characterized in that: fuel duct front end is connected with oil sprayer mouth end, connection gap, fuel duct rear end filter cleaner front end, filter cleaner rear end, gap is connected with graceful oil pipe, and the back-end location inside of gap filter cleaner is embedded with orifice valve.Its pressure wave that can improve high pressure oil pump outlet port is delivered to conformity and the controllability of oil sprayer mouth end, reduces the repeatedly circulating fuel injection quantity scattered error of oil sprayer, improves engine speed fluctuation and vibration noise.
Description
Technical field
The utility model relates to the horizontal rifle of a kind of diesel engine oil supply system high pressure, belongs to the technical field of diesel engine oil supply system design.
Background technique
Traditional diesel engine oil supply system parts are mainly oil transfer pump, fine cleaner, high pressure oil pump, high-pressure oil pipe, the horizontal rifle of high pressure, oil sprayer and low-voltage fuel pipeline composition; Oil transfer pump running produces negative pressure by diesel oil sucking-off from fuel tank, diesel oil enters into oil transfer pump entrance after low-voltage fuel pipeline and strainer, oil transfer pump is built diesel oil compression to press and be transported to high pressure oil pump through fine cleaner, high pressure oil pump will be transported to oil sprayer through high-pressure oil pipe and the horizontal rifle of high pressure after diesel oil boil down to high pressure fuel, and oil sprayer burns fuel spraying in engine chamber.
The horizontal rifle of traditional high pressure is provided with gap filter cleaner in its ingress, and gap filter cleaner carries out final filtration to the diesel oil that enters oil sprayer, the fuel duct that the horizontal rifle of high pressure after the filter cleaner of gap is certain internal diameter, fuel duct act as conveying high-pressure diesel oil; Therefore, the horizontal rifle of traditional high pressure act as filtering and conveying high-pressure diesel oil.
At present, in mechanical pump and electronically controlled unit pump diesel engine fuel-firing supply system, because high-pressure oil pipe length is very long, cause the pressure wave in high pressure oil pump outlet port to be delivered to the bad stability of oil sprayer mouth end, finally cause the repeatedly circulating fuel injection quantity scattered error of oil sprayer to become large, finally cause engine speed fluctuation and vibration noise large.
Summary of the invention
The purpose of this utility model is to provide the horizontal rifle of a kind of diesel engine oil supply system high pressure, its pressure wave that can improve high pressure oil pump outlet port is delivered to conformity and the controllability of oil sprayer mouth end, reduce the repeatedly circulating fuel injection quantity scattered error of oil sprayer, improve engine speed fluctuation and vibration noise.
The technical solution of the utility model is achieved in that the horizontal rifle of a kind of diesel engine oil supply system high pressure, formed by fuel duct, gap filter cleaner, orifice valve, it is characterized in that: fuel duct front end is connected with oil sprayer mouth end, connection gap, fuel duct rear end filter cleaner front end, filter cleaner rear end, gap is connected with graceful oil pipe, and the back-end location inside of gap filter cleaner is embedded with orifice valve.
Good effect of the present utility model is conformity and the controllability that its pressure wave that can improve high pressure oil pump outlet port is delivered to oil sprayer mouth end, reduce the repeatedly circulating fuel injection quantity scattered error of oil sprayer, improve engine speed fluctuation and vibration noise, in the time that pressure wave arrives the horizontal rifle of high pressure ingress from high pressure oil pump outlet end, pressure wave is carried out filtering by orifice valve, pressure wave after filtration is delivered to oil sprayer mouth end, has improved the stability of pressure wave.
Brief description of the drawings
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of horizontal rifle of high pressure for diesel engine oil supply system, formed by fuel duct 1, gap filter cleaner 2, orifice valve 3, it is characterized in that: fuel duct 1 front end is connected with oil sprayer mouth end, fuel duct 1 connection gap, rear end filter cleaner 2 front ends, filter cleaner 2 rear ends in gap are connected with graceful oil pipe, and the back-end location inside of gap filter cleaner 2 is embedded with orifice valve 3.
The fuel oil that high pressure oil pump is got is transported to the horizontal rifle entrance of high pressure through high-pressure oil pipe, orifice valve 3 is opened under high pressure fuel effect, pressure wave is carried out to filtering simultaneously, filtered high pressure fuel is after 2 filterings of gap filter cleaner, be transported to oil sprayer mouth end by fuel duct 1, then high pressure fuel injection burns in engine chamber.
