Motor monitoring system of three-roller continuous tube-rolling mill

Abstract

The invention provides a motor monitoring system of a three-roller continuous tube-rolling mill, which comprises a plurality of groups of thermistors, temperature inspection instruments, PLC (Programmable Logic Controller) equipment and a master-control upper machine, wherein the monitoring position on each motor of the three-roller continuous tube-rolling mill is embedded with one group of thermistor, and the thermistor embedded on each motor is connected with one temperature inspection instrument; the temperature inspection instrument obtains temperature information of the connected thermistor and sends the temperature information to the PLC equipment; the PLC equipment sends the temperature information to the master-control upper machine; and the master-control upper machine analyzes the safety of the motors of the three-roller continuous tube-rolling mill according to the temperature information of the thermistor of each motor. One group of thermistor adopts a plurality of thermistor monomers to measure the temperature of the motors, so that the reliability of motor monitoring is increased. The data transmission of the PLC equipment and the master-control upper machine adopts an Ethernet network, so that the rapid transmission of data and the safety of data transmission can be effectively ensured. The system is beneficial to maintenance for the motors of the three-roller continuous tube-rolling mill.

Description

technical field [0001] The invention relates to the monitoring technology of a continuous pipe rolling mill, and in particular to a motor monitoring system suitable for a three-roll continuous pipe rolling mill. Background technique [0002] Generally, the operation of the motor of the three-roll mill is more complicated. The three-roll mill has 5 to 7 racks, and each rack has 3 motors, so there are 15 to 21 motors in one mill. main motor. The ambient temperature in the working area of ​​the continuous pipe mill motor is high, the overload multiple is large, and the probability of failure may be relatively high. When any motor breaks down, the whole rolling mill needs to be shut down for maintenance. [0003] In order to ensure the normal and effective operation of the three-roll mill, it is necessary to effectively monitor and predict the status of each motor of the three-roll mill in real time. Therefore, it is very necessary to establish an independent, portable real-t...
