Nozzle oil supply system

Abstract

The invention discloses a nozzle oil supply system. The nozzle oil supply system comprises a high-pressure fuel supply system for providing high-pressure fuel, a high-pressure gas supply system for providing high-pressure gas, a spraying oil pipe, and a fuel conversion device, wherein the two ends of the spraying oil pipe are respectively connected with a nozzle and the fuel conversion device; the high-pressure fuel supply system is connected with the fuel conversion device, and presses high-pressure fuel, flowing into the fuel conversion device, into the spraying oil pipe under the effect of the fuel conversion device; and the high-pressure gas supply system is communicated with the spraying oil pipe, outwards sprays part fuel in the spraying oil pipe from the nozzle when the high-pressure fuel supply system is closed, and presses the remainder fuel in the spraying oil pipe into the fuel conversion device for outwards flowing. The nozzle oil supply system cannot generate the carbon deposition due to long-time stop of an engine, so that the inspection of the engine before working after the long-time stop is reduced, the fault caused by the blockage of the spraying oil pipe due to the carbon deposition is prevented, and the flight safety is guaranteed.

Description

technical field [0001] The invention relates to the field of engines, in particular to a nozzle oil supply system. Background technique [0002] At present, when the engine stops working, high-pressure gas is often introduced to blow off the remaining oil and formed carbon deposits on the end surface of the nozzle, so as to avoid the formation of carbon deposits formed by the remaining oil, which will cause nozzle blockage, cause engine failure and affect flight safety. But in the prior art, only introduce high-pressure gas to blow off the remaining oil on the nozzle and the carbon deposit that has formed, and also there is remaining oil in the injection system of engine, when engine is parked for a long time, these remaining oils will produce new Carbon deposits will cause blockage of the injection oil passage, which will cause engine failure and affect flight safety. Contents of the invention [0003] The present invention provides a nozzle oil supply system to solve th...
