Abstract

The application relates to a temperature data processing method for a test bearing of a compressor, and the method comprises the following steps of continuously obtaining the bearing temperature of the test bearing; obtaining bearing temperature rise according to the bearing temperature of the test bearing at the current moment and the bearing temperature of the test bearing at the previous moment, and obtaining a bearing temperature rise speed according to the bearing temperature rise and the time difference between the current moment and the previous moment; judging the bearing working stateaccording to the bearing temperature rise speed, determining that the test bearing works abnormally if the bearing temperature rise speed is greater than a preset value, and determining that the testbearing works normally if the bearing temperature rise speed is not greater than the preset value. The temperature data processing method for the test bearing of the compressor provided by the application effectively monitors the temperature rise to obtain a good transient warning capability and prevent the misleading and paralysis caused by not reaching the limit value to the field personnel.

Description

technical field [0001] The application belongs to the technical field of aero-engine test data processing, and in particular relates to a method and device for processing temperature data of a compressor test bearing. Background technique [0002] Bearings in rotating devices (such as aeroengines) are subject to high-speed, heavy-load operation risks, and the index that best reflects the operating status of the bearings is the bearing temperature. Due to the suddenness of faults, the monitoring of abnormal changes in bearing temperature needs to have good real-time and recognizability. [0003] At present, the abnormal detection of bearing temperature usually uses the data acquisition system to measure the bearing temperature through the sensor, and then displays it through the host computer interface, and sets the signal alarm after the upper limit is exceeded. At the same time, during the test, the operator regularly records the data to form a form, and compares the tempe...
