Combined type rotating machinery combined failure diagnose test apparatus

Abstract

The present invention provides a combined rotating machinery complex failure diagnosis and test device. The surface of the base (8) is provided with T-shaped grooves with the required number. A plurality of brackets (7) which are independent from each other are installed on the base (8) through the T-shaped grooves. The brackets (7) is provided with an electric motor (1) and a device which is driven by the electric motor and can combine various failures through the moving and transposition of the brackets (7) in the T-shaped groove. Three T-shaped grooves which are arranged parallelly and have same magnitude and shape are provided. The electric motor (1) is connected with a component wherein through a coupling (6), and the components are connected with each other with the coupling (6). The components comprise a test shaft (2), a gear box (3), a transition bearing support (4) and a load (5). The invention can provide a single failure and multiple complex failures for executing diagnosis test. Several hundreds of working states can be executed with raw data collection, analysis and research. The test device has the advantages of simple structure, intuition, convenient assembly, without damage in loading and unloading, accurate data and the like. The operability of the failure diagnosis test is greatly increased.

Description

technical field [0001] The invention relates to a combined rotary machinery composite fault diagnosis test device, which can combine multiple multiple composite faults without damage, flexibly and conveniently for diagnostic tests, and belongs to the innovative technology in the manufacturing field of rotary machinery fault diagnosis test devices. Background technique [0002] At present, conventional unit fault diagnosis technology at home and abroad has many shortcomings such as low diagnostic accuracy and difficulty in realizing online rapid diagnosis in practical applications. Even after introducing many new methods of artificial intelligence and expert systems, the accuracy of fault diagnosis is still Difficult to improve. Especially for the complex faults of the unit, such as the unit shafting, gearbox, bearing housing, etc., the accurate diagnosis of the compound faults that are likely to occur from internal or related component defects has always been a bottleneck th...
