Abstract

The present invention provides a full-time domain frequency spectrum analysis test device and method for regulating fuel pumps, which solves the problem that existing test methods for regulating fuel pumps are not perfect and cannot simulate the dynamic information of regulating fuel pumps under actual flight conditions, resulting in complete test results The performance and reliability are not high, and it cannot provide effective reference for the development and performance evaluation of the fuel pump. The test device includes a drive unit, a lubricating oil unit, a hydraulic source, a safety auxiliary unit, a data acquisition unit, a data processing unit, a first load, a second load, a first hand pump, a second hand pump and four pressure sensors.

Description

technical field [0001] The invention belongs to the technical field of performance test of a fuel pump regulation, and in particular relates to a full-time domain frequency spectrum analysis test device and a test method of a fuel pump regulation. Background technique [0002] An underwater power system adopts an open cycle thermodynamic propulsion system to adjust the dynamic characteristics of the fuel pump, which has a direct impact on the working stability and reliability of the entire power propulsion system. [0003] The regulating fuel pump is mainly composed of a plunger pump for supercharging and a two-speed pressure regulating valve for regulating and controlling the fuel pressure after supercharging. Its main function is to suck the fuel stored in the fuel tank and Pressurize to provide the combustion chamber with a certain pressure and flow of working medium, and can automatically adjust the fuel flow into the combustion chamber according to different speed requi...
