Self-learning fault monitoring and alarming system of three-legged centrifuge

Abstract

The invention discloses a self-learning fault monitoring and alarming system of a three-legged centrifuge. An acceleration sensor is installed on a centrifuge motor or a base close to the motor, a temperature sensor is installed on the side surface in a centrifuge body, and a data acquisition card collects data of the acceleration sensor and the temperature sensor and sends the data to an industrial control computer. The industrial control computer operates the fault monitoring and alarming system to monitor a centrifuge in real time. The system has the advantages that the vibration-temperature determination threshold is automatically set through vibration-temperature signal collection when the centrifuge is put into use; the vibration data is collected after the centrifuge works for a period of time, and the vibration threshold of the centrifuge is predicted for the next time period through self-learning, so as to avoid the false determination caused by the rigorous initial thresholdsetting.

Description

technical field [0001] The invention relates to a self-learning fault monitoring and alarm system for a three-legged centrifuge. Background technique [0002] A centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials that need to be separated. Centrifuges are divided into filter centrifuges, decanter centrifuges, etc., which are composed of centrifuge tubes, tube sleeves, centrifuge bottles and other components, and are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding and other departments. [0003] The three-legged centrifuge is named because the bottom support is three columns arranged in an equal triangle. Three-legged centrifuge is a solid-liquid separation equipment, mainly suitable for solid-liquid two-phase separation. Its working principle is: the centrifuge generates strong centrifugal force through high-speed rotation, and its centrifugal separation...

AI Technical Summary

Problems solved by technology

[0004] The common faults of the three-legged centrifuge include increased noise and high temperature rise. If the status of the centrifuge is not monitored in real time during the working process, once a fault occurs, it is easy to cause damage to the centrifuge.

[0008] 1) Different people have different perceptions of vibration, and there are differences in their subjective feelings, which may lead to misjudgment;

[0009] 2) Abnormal vibration cannot be detected in time, and there is a lag in its solution
