Abstract

A device for monitoring the oil film thickness of an in-use ball mill sliding bearing comprises a data acquisition process part, a data processing and transmitting part, and a data analyzing and controlling part. The data acquisition process part is connected with the data processing and transmitting part 2; the data processing and transmitting part is connected with the data analyzing and controlling part; and the data analyzing and controlling part is connected with the data acquisition process part. By adoption of a method for monitoring the oil film thickness of the in-use ball mill sliding bearing, real-time monitoring of the oil film thickness in the working process of the ball mall sliding bearing can be achieved; meanwhile, real-time data relating to friction in the working process of the ball mill can be extracted. Weak current is adopted for acquisition in the whole monitoring process, the device can keep working after installation, and thus influences on manufacturing operation of the device are avoided; by adoption of the measuring method and algorithm, accuracy and reliability of the data can be guaranteed; in addition, the method overcomes the shortages of other traditional detection methods and has the function of self-learning. The device and method provide more reliable evidences for maintenance of the ball mill and analysis of friction faults.

Description

technical field [0001] The invention belongs to the technical field of oil film thickness monitoring of sliding bearings of large ball mills, and relates to an oil film thickness monitoring technology, in particular to a monitoring device and a monitoring method for the oil film thickness of sliding bearings of ball mills in use. Background technique [0002] As we all know, the ball mill is an important production equipment in the beneficiation and cement industry, and it is the key equipment for crushing materials after they are crushed. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries. As an important part of the ball mill, it supports sliding bearings under heavy load, low speed, heavy load Under high-speed high-torque start-up and under the action of equipment vibration and radial impact, metal fatigue occurs i...
