Fuel pump performance test system, method and main system

Abstract

The invention provides a fuel oil pump performance test system and method, and a main system. The fuel oil pump performance test system comprises a fuel tank, an electric heating system, a circulatingwater system, a circulating water control system, a valve control system, a valve, a temperature, pressure, and flow detecting instrument, a tested fuel oil pump, a voltage and current detecting instrument, a PLC control system and an instrument control system. The electric heating system is used for receiving a set temperature sent by the PLC control system, detecting the current temperature ofthe fuel tank, and comparing the current temperature of the fuel tank with a set temperature. The circulating water control system is used for controlling the circulation amount of circulating water according to the comparison result. The temperature, pressure, and flow detecting instrument is used for detecting a valve parameter. The instrument control system is used for sending control instruction information to the valve control system to control the valve to increase the opening degree or reduce the opening degree. Therefore, the inlet oil temperature of the fuel oil pump can be adjusted precisely; and fault phenomena of outward oil leakage of the fuel oil pump, wire aging and difficult controlling of the inlet fuel temperature are reduced.

Description

technical field [0001] The invention relates to the technical field of fuel oil pumps, in particular to a fuel oil pump performance test system, method and main system. Background technique [0002] At present, the development of my country's aerospace industry has made remarkable achievements. In order to improve the performance of aircraft and other equipment, make the engine exert its maximum efficiency and ensure its safe and normal operation, it is necessary to provide a series of guarantees, the most basic of which is In order to improve the high-altitude performance of the fuel supply system and overcome the resistance of fuel flow, the medium-frequency low-pressure fuel pump is an indispensable accessory. The medium-frequency low-pressure fuel pump enables the engine to be fully lubricated and cooled. Prevent the propeller and the leading edge of the wing from icing, and ensure the working accuracy of the instrument, etc. At present, an ordinary jet aircraft or a rela...

AI Technical Summary

Problems solved by technology

At present, an ordinary jet aircraft or a relatively complete hydraulic transmission system carries more than ten medium-frequency and low-pressure fuel oil pumps. However, after a certain period of use, oil leakage from the fuel oil pump and aging of the wires often occur. Due to the lack of fuel oil pump testing equipment, the user cannot undertake the repair of the fuel oil pump and the performance test after repair, and adjust the temperature of the fuel inlet during the test by simulating the environment during flight, etc.

[0003] In view of the above-mentioned fuel oil pump failures such as oil leakage from the fuel oil pump, aging wires, and poor control of the inlet fuel temperature, there is no effective solution for the lack of fuel oil pump testing equipment.
