Aviation sliding oil pump comprehensive testbed

Abstract

The invention provides an aviation sliding oil pump comprehensive testbed. The aviation sliding oil pump comprehensive testbed comprises a metering oil tank, a main oil tank and a tested sliding oil pump, and is characterized in that the tested sliding oil pump is connected with the lower end of the main oil tank and the lower end of the metering oil tank through four oil supply pipelines, and thetested sliding oil pump is connected with the top of the main oil tank through two oil return pipelines; a circulating oil way and an air pressure adjusting loop are arranged between the metering oiltank and the main oil tank respectively; and the tested sliding oil pump is connected with a driving motor through a gearbox. According to the aviation sliding oil pump comprehensive testbed, the requirements of the sliding oil pumps with different specifications and multiple test items can be met; and each test item of the tested sliding oil pump can be completed by one-time installation, and the disassembly and assembly workload is reduced.

Description

technical field [0001] The invention relates to a comprehensive test bench for aviation lubricating oil pumps. Background technique [0002] Aviation lubricating oil pump is an important component of the aircraft lubricating oil system. It has the characteristics of light weight, compact structure, one-axis multi-stage, high temperature resistance, high speed, and working in a vacuum environment. It is mainly used for lubricating oil for engine bearings and transmission gears. The quality of transportation and recovery is directly related to the flight safety of the aircraft. During the scientific research process, the lubricating oil pump needs to complete the performance test and failure cause analysis under different working conditions, and the running-in and test must be completed before installation. Existing equipment cannot simultaneously meet the requirements of lubricating oil pump speed 0-12000r / min, test temperature 0-200°C, oil inlet pressure of the tested lubric...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a comprehensive test bench for aviation lubricating oil pumps, which solves the problem that the existing equipment cannot simultaneously meet the requirements of the lubricating oil pump speed of 0-12000r / min, the test temperature of 0-200°C, and the oil inlet pressure of the tested lubricating oil pump -95 The requirement of ~100KPa, as well as the running-in test, sealing test, ground performance test, pressure regulating valve test, and high-altitude performance test of the lubricating oil pump need to be completed on different test benches, and the tested lubricating oil pump needs to be disassembled and assembled many times, and the work efficiency is low question
