Example Embodiment

[0022] Example 1

[0023] A lubricating oil pump test bench, including a test bench on which a power transmission system, a lubricating oil system, a vacuum system, a cooling system, and an electrical control system are installed; the lubricating oil system is respectively connected with the power transmission system, the vacuum system, and the cooling system , The electrical control system and the lubricating oil pump are connected; the lubricating oil pump is installed on the test bench and connected to the lubricating oil system through pipelines.

[0024] The lubricating oil system includes a main oil tank 1, a metered oil tank 2, a pipeline system; the main oil tank 1 and a metered oil 2 tank are installed on a liftable base. The pipeline system includes a metering oil tank replenishing pipeline; the metering lubricating oil tank replenishing pipeline is arranged between the main oil tank and the metering oil tank. There are 5 outlets in the main fuel tank, 3 of which are oil...

Example Embodiment

[0034] Example 2

[0035] Such as figure 1 — Figure 4 As shown, the pressure on the upper part of the main oil tank is closed-loop controlled by the electric regulating valve TF3 and pressure transmitter P1 to keep the vacuum pump working continuously and the pressure in the main oil tank stable. At this time, the conditions required for the oil pump test are reached, and the sliding operation can be started. Single-stage flow test of oil pump.

[0036] When the flow measurement test of a certain level of the test oil pump is performed, the electric switch valve DK1 on the connecting pipeline of the main oil tank 1 and the metering oil tank 2 needs to be opened, so that the liquid level in the metering oil tank reaches the upper limit before the flow measurement can be performed. test. The on-off valve DK1 is automatically controlled by the electrical control system. The tester only needs to press the metering oil tank filling button on the console to complete the oil replenishm...

Abstract

The invention provides a lubricating oil pump test bed. The test bed comprises a test bed frame, and a power transmission system, a lubricating oil system, a vacuum system, a cooling system and an electrical control system are installed on the test bed frame; the lubricating oil system is connected to the power transmission system, the vacuum system, the cooling system, the electrical control system and a lubricating oil pump; and the lubricating oil pump is arranged on the test bed frame and is connected to the lubricating oil system through pipelines. The test bed can bear a high-altitude performance test and a ground reliability assessment test of the lubricating oil pump, and is convenient to disassemble and assemble, reasonable in arrangement and convenient to overhaul and maintain.

Description

technical field [0001] The invention relates to a lubricating oil pump test device, in particular to an aviation gas turbine engine lubricating oil pump test bench. Background technique [0002] The lubricating oil pump is an important component of the lubricating oil system of the aviation gas turbine engine. It is mainly used for the transportation and recovery of the lubricating oil of the bearings and transmission gears of the aviation gas turbine engine. The aviation gas turbine engine lubricating oil system is an essential part of the aviation gas turbine engine, and the quality and performance of the lubricating oil pump directly affect the performance of the aviation gas turbine engine lubricating oil system. [0003] The performance of the lubricating oil pump is various. When controlling whether the performance of the lubricating oil pump meets the relevant technical production and use standards, multiple test sites and multiple sets of test supporting equipment ar...
