Problems solved by technology

The engine fuel supply system of the test bench needs to provide fuel for different test engines, and the required flow range of different test engines is 0.2g / s~47g / s. However, in the prior art, the design of the test bench engine fuel supply system is complicated and cannot Large-scale adjustment of oil supply, at the same time, it is impossible to monitor the relevant parameters of the entire oil supply system in a timely and effective manner, which leads to the accuracy of the entire oil supply system and the supply range of the oil supply system

Abstract

An oil supply system of an engine test bed comprises a main oil inlet path, a first load branch, a first branch and a main oil return path. The first load branch and the first branch are arranged in parallel, inlets of the first load branch and the first branch are communicated with the main oil inlet path, and outlets of the first load branch and the first branch are communicated with the main oil return path; and according to the oil supply system of the engine test bed, the oil supply amount can be adjusted in a large range by arranging the two branches connected in parallel, meanwhile, related parameters of the whole oil supply system can be effectively monitored in time by arranging related valves and pressure gauges for monitoring, and then the precision of the whole oil supply system is improved.

Description

technical field [0001] The invention relates to the technical field of test bench testing, in particular to an oil supply system for an engine test bench. Background technique [0002] The engine fuel supply system of the test bench is an important part of the engine ground test, and it is used to provide fuel to the experimental engine. The engine fuel supply system of the test bench needs to provide fuel for different test engines, and the required flow range of different test engines is 0.2g / s~47g / s. However, in the prior art, the design of the test bench engine fuel supply system is complicated and cannot Large-scale adjustment of the oil supply, at the same time, it is impossible to effectively monitor the relevant parameters of the entire oil supply system in a timely manner, which in turn leads to the accuracy of the entire oil supply system and the supply range of the oil supply system. Contents of the invention [0003] The technical problem of the present invent...
