Embodiment 1

[0023] A lubricating oil pump test bench comprises 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 connected to the power transmission system, the vacuum system, and the cooling system respectively , electrical control system, and lubricating oil pump; 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 metering oil tank 2, and a pipeline system; the main oil tank 1 and the metering oil tank 2 are installed on a liftable base. The pipeline system includes a metered oil tank replenishment pipeline; the metered oil tank replenishment pipeline is arranged between the main oil tank and the metered oil tank. There are 5 outlets in the main fuel tank, 3 outlets for fuel supply and 2 outlets as spare outlets. The...

Embodiment 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 the pressure transmitter P1 to keep the vacuum pump working continuously and the pressure in the main oil tank stable. Oil pump single stage flow test test.

[0036] When carrying out the flow measurement test of a certain stage of the test lubricating oil pump, it is necessary to open the electric switch valve DK1 on the connecting pipeline between the main oil tank 1 and the metering oil tank 2, so that the liquid level in the metering oil tank reaches the upper limit, and then the flow measurement can be performed test. The on-off valve DK1 is automatically controlled by the electrical control system, and the test personnel only need to press the oil filling button of the metering oil tank on the operating table to complete the oil replenishment of the metering oil tank. Then select the metering oil circuit (...

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...
