Problems solved by technology

[0002] After the engine is delivered to the customer, it needs regular maintenance. During the maintenance, the time for the engine to decelerate within the predetermined value range is an important indicator for detecting the flexibility of the engine rotor. However, in the prior art, the test method for engine deceleration , there is no effective device and method

Abstract

The invention relates to a drop rotation time test bench, which comprises a case and a panel fixedly connected with the case, the panel is provided with an electrical interface support, a rear cover, a panel air inlet and a computer installation part. The electrical interface support comprises a grounding terminal, an input and output electric connector, a power switch, an electromagnetic valve switch and an electrical interface support exhaust outlet. And a VPX data acquisition device is arranged in the case and is electrically connected with the input and output electric connector, the power switch, the electromagnetic valve switch and the computer. According to the rotation reduction time test bench and the test method thereof, the test of the rotation reduction of the engine is realized, and an effective device and a test means are provided for the test of the flexibility of the rotor in the maintenance process of the engine.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to a down-rotation time test bench and a testing method thereof. Background technique [0002] After the engine is delivered to the customer, it needs regular maintenance. During the maintenance, the time for the engine to decelerate within the predetermined value range is an important indicator for detecting the flexibility of the engine rotor. However, in the prior art, the test method for engine deceleration , there is no effective device and method. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, and to provide a down-rotation time test bench and a test method thereof. [0004] The technical solution of the present invention is: a down-rotation time test bench, including a case and a panel fixedly connected with the case; the panel is provided with an electrical interface bracket, a re...
