The model utility content
In order to overcome defects, the utility model provides a kind of fuel system for diesel engine of architecture advances, and the fuel system for diesel engine engine speed of this architecture advances is stable; fuel-oil atmozation is even, has avoided the oil dripping phenomenon, has protected environment; save the energy, prolonged service life of aeroengine.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of fuel system for diesel engine of architecture advances, comprise fuel tank, fuel circulating pump, filter cleaner and Injection Pump, described fuel tank, fuel circulating pump, filter cleaner is connected pipeline with Injection Pump and connects, pipeline between filter cleaner and the Injection Pump is provided with solenoid valve, Injection Pump is provided with oil nozzle, described oil nozzle comprises needle-valve body and needle-valve, described needle-valve body is comprised of body and end body, be provided be connected successively upper in the end body, in, the downforce chamber, wherein go up, the downforce chamber is the cone table shape structure, middle pressure chamber is cirque structure, described needle-valve is located in the needle-valve body, the head of needle-valve is and the cone table shape structure of the coupling of pressure chamber up and down, also is provided with billiard table on the cone table shape head of described needle-valve.
As further improvement of the utility model, described solenoid valve is provided with over speed switch.
As further improvement of the utility model, described downforce chamber is provided with some pits near the sidewall of middle pressure chamber.
As further improvement of the utility model, described upward pressure chamber away from middle pressure chamber one side diameter and downforce chamber away from the diameter of middle pressure chamber one side than being 4:3.
As further improvement of the utility model, the diameter of cone table shape structure is 4:3 with the diameter ratio of billiard table on the described needle-valve.
As further improvement of the utility model, be provided with some guiding gutters in the described middle pressure chamber.
The beneficial effects of the utility model are: the utility model is by being divided into upper, middle and lower Three pressures chamber with needle-valve body internal pressure chamber; and at top, downforce chamber sidewall bowl configurations is set; both saved the volume of pressure chamber; improved again the atomizing uniformity of fuel oil; so that fuel oil fully burns; the oil dripping phenomenon of avoiding; saved the energy, by at solenoid valve over speed switch being set, when engine speed surpasses setting value; switch is opened automatically; avoid motor to cause overspeed rotation because fuel feeding is out of control, protected motor, over-emitting black exhaust when having avoided its work; protect environment, improved the motor safety in utilization.
