Problems solved by technology

[0002] The existing domestic aero-engine test benches all use a set of test benches for one type of engine. In terms of process equipment, one type of engine also uses a set of hydraulic pump load system, and two engines cannot be tested at the same time.
Thereby there are following problems: 1, every type of engine must have corresponding hydraulic pump load system, thereby the quantity of hydraulic pump load system is constantly increasing, the money of expending and land resources increase, and the production cost of engine improves
2. It is not possible to test the two engines at the same time, which will affect the efficiency of the test

Embodiment 1

[0020] In this embodiment, the structural block diagram of the hydraulic pump load system that can be used for the ground test of two types of aero-engines is as follows: figure 1 As shown, the hydraulic schematic diagram is as follows Figure 4 As shown, it includes the hydraulic pump load station b1, and the first oil inlet pipeline that provides pressure oil for the first engine hydraulic pump and the second oil inlet pipeline that provides pressure oil for the second engine hydraulic pump are connected in parallel on the oil outlet pipe of the hydraulic pump load station. The oil inlet pipeline is provided with a flow regulating valve on the oil return pipeline of the hydraulic pump load station.

[0021] from Figure 4 It can be seen that the hydraulic pump load station b1 includes a pressure oil tank 9, which is connected with a pressurized air circuit composed of a gas cylinder 1, a pressure reducing valve 2, an air filter 3, and a needle valve 4, and the exhaust contr...

Embodiment 2

[0024] In this embodiment, the structural block diagram of the hydraulic pump load system that can be used for the ground test of two types of aero-engines is as follows: figure 2 As shown, the hydraulic schematic diagram is as follows Figure 5 shown. The difference from Embodiment 1 is that the first engine hydraulic pump b2 requires oil leakage. During the test run, the oil leakage port of the first engine hydraulic pump is connected to the oil leakage pipe joint 30 provided on the pressure oil tank 9 through a pipe fitting.

Embodiment 3

[0026] In this embodiment, the structural block diagram of the hydraulic pump load system that can be used for the ground test of two types of aero-engines is as follows: image 3 As shown, the hydraulic schematic diagram is as follows Image 6 shown. The difference from Embodiment 1 is that both the first engine hydraulic pump b2 and the second engine hydraulic pump b3 need to leak oil. During the test run, the oil leakage port of the first engine hydraulic pump and the oil leakage port of the second engine hydraulic pump respectively pass The pipe fitting is connected with the oil leakage pipe joint 30 provided with the pressure oil tank 9 .

Abstract

The invention discloses a hydraulic pump loading system for simultaneously performing a ground test on two types of aero-engines. The hydraulic pump loading system comprises a hydraulic pump loading station, wherein a first oil inlet pipeline for providing pressure oil to a first engine hydraulic pump and a second oil inlet pipeline for providing pressure oil to a second engine hydraulic pump are connected to an oil outlet tube of the hydraulic pump loading station in parallel, and a flow rate regulating valve is arranged on the oil returning pipeline of the hydraulic pump loading station; during test run, the oil inlet of the first engine hydraulic pump and the oil inlet of the second engine hydraulic pump are respectively connected to the first oil inlet pipeline and the second oil inlet pipeline, and an oil outlet of the first engine hydraulic pump and an oil outlet of the second engine hydraulic pump are respectively connected to the oil returning pipeline of the hydraulic pump loading station by virtue of a quick joint and a tube fitting, and are connected in front of the flow rate regulating valve.

Description

technical field [0001] The invention belongs to the technical field of aero-engine ground testing, in particular to a hydraulic pump load system for aero-engine ground testing. Background technique [0002] The existing domestic aero-engine test benches all use one set of test benches for one type of engine. In terms of process equipment, one type of engine also uses one set of hydraulic pump load system, and it is not possible to test two engines at the same time. Therefore, there are the following problems: 1. Each type of engine must have a corresponding hydraulic pump load system, so the number of hydraulic pump load systems continues to increase, the cost of capital and land resources increases, and the production cost of the engine increases. 2. The two engines cannot be tested at the same time, which affects the efficiency of the test. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provid...
