Problems solved by technology

[0002] At present, there is no special device for removing the dissolved air in the lubricating oil in the domestic aero-engine lubricating oil contact device test equipment, which causes a lot of oil foam during the test process, which seriously affects the accuracy of the test; and for the current various types of nozzles in the installation Since the oil receiving cup cannot be adjusted for expansion and rotation according to the different oil receiving distance angles when receiving oil, it cannot be tested for different types of nozzles, and the compatibility is poor.

Abstract

The invention relates to a device for testing the flow of a lubricating oil nozzle of an engine, belonging to the technical field of space shuttle engines. The device comprises an oil receiving cup, a first switching pipe, a second switching pipe, a third switching pipe, a working room, an oil return tank, an oil collecting pipe, a two-position three-way electromagnetic valve, an oil metering cup, a first electromagnetic valve, a second electromagnetic valve, an oil return pump, an oil supply pump and a combined oil tank, wherein the combined oil tank comprises an oil collector, a vacuum oil tank, a consumption oil tank, a third electromagnetic valve, a fourth electromagnetic valve and a vacuum pump. With the structure of a vacuum combined split oil tank, the device can remove air dissolved in lubricating oil. An upper and a lower split oil tanks are used, wherein the lower oil tank is used for supplying oil, and the upper vacuum oil tank is used for removing the dissolved air. For the compatibility of different types of nozzles, the designed oil receiving cup can flex and rotate according to different oil receiving distances and angles, can be used for testing different types of nozzles and reduce the labor intensity of workers.

Description

technical field [0001] The invention belongs to the technical field of aircraft engines, and in particular relates to an engine lubricating oil nozzle flow test device. Background technique [0002] At present, there is no special device for removing the dissolved air in the lubricating oil in the domestic aero-engine lubricating oil contact device test equipment, which causes a lot of oil foam during the test process, which seriously affects the accuracy of the test; and for the current various types of nozzles in the installation Since the oil receiving cup cannot be adjusted for stretching and rotating according to the different angles of the oil receiving distance when receiving oil, it cannot be tested for different types of nozzles, and the compatibility is poor. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an engine lubricating oil nozzle flow test device. By adding a combined oil tank and an adjustab...
