A kind of oil supply system of turbojet engine and precise control method of rotating speed

Abstract

The invention provides an oil supply system of a turbojet engine and a precise control method of the rotating speed. The oil supply system comprises a first oil pump, a second oil pump and a control unit, wherein the first oil pump is connected with a first nozzle; the first nozzle is connected to the engine to form a first oil supply pipeline; the first oil supply pipeline is used for controllingthe maximum oil inlet amount and controlling the increment of the rotating speed of the engine in unit time; the second oil pump is connected with a second nozzle; the second nozzle is connected to the engine to form a second oil supply pipeline; the second oil supply pipeline is used for controlling the minimum oil inlet amount; the power of a first motor is larger than that of a second motor, and the diameter of the first nozzle is larger than that of the second nozzle; the control unit is used for controlling the change of the oil supply amount of the first oil supply pipeline and / or the second oil supply pipeline; the oil supply amount can be rapidly increased, so that the increment of the rotating speed of the engine in unit time is controlled; and the oil supply amount can be rapidly increased and decreased, and the micro oil supply amount can be accurately controlled, so that the accurate control of the rotating speed of the engine is realized. According to the oil supply system of the turbojet engine and the precise control method of the rotating speed, the requirements of speed and precision are met at the same time, so that the control precision of the rotating speed ofthe engine is improved.

Description

Technical field [0001] The present invention relates to the field of vortex engines, and in particular, to a water supply system and an accurate control method of a vortex engine. Background technique [0002] At present, the control method of the existing vortex engine is connected to the outlet opening through a oil pump, and the oil supply amount is controlled by controlling the speed or working time of the oil pump motor. [0003] There are several defects in existing programs: 1. Alternative oil pumps control the amount of oil, the oil pump motor power will affect the maximum speed of the turbojet engine, which will also cause the engine speed to speed; the oil pump motor power consensus causing accurate control of oil Low control precision. 2, the control is not flexible enough, controlling the oil pump motor is difficult to add slowly or slowly slow down. 3, a single oil pump cannot meet the rapid growth and precise control simultaneously. [0004] For example, the instead...

AI Technical Summary

Problems solved by technology

[0003] The existing scheme mainly has several defects: 1. A separate oil pump controls the oil intake, and the low power of the oil pump motor will affect the maximum speed of the turbojet engine, which will also cause the engine to speed up too slowly; the large power of the oil pump motor makes it impossible to accurately control the oil intake , low control precision

2. The control is not flexible enough, it is difficult to control the oil pump motor to achieve fast increase and slow decrease or fast slow down increase

3. A single oil pump cannot satisfy rapid growth rate and precise control at the same time

This patent uses a separate oil pump to control the oil intake, which still has the following disadvantages: it cannot meet the requirements of high power and high precision at the same time, and the minimum oil intake of high-power oil pumps is generally high, resulting in low precision; the minimum oil intake of small-power oil pumps is low. , but at the same time the maximum oil intake is not high, and it is impossible to achieve rapid and large oil intake
