Novel lubrication control system for steel rolling main motors

Abstract

The invention discloses a novel lubrication control system for steel rolling main motors. The novel lubrication control system comprises a control cabinet of a main electric room and a PLC (programmable logic controller) of the control cabinet of the main electric room. A CPU (central processing unit) of the PLC of the control cabinet of the main electric room is connected with a touch screen of the main electric room by the internet, two channels of information are transmitted from the control cabinet of the main electric room, one channel of information is transmitted onto a touch screen of a main assistant control room, and the other channel of information is transmitted to an upper computer. The novel lubrication control system has the advantages of reasonable structure, large quantity of communication and control information, accuracy and reliability.

Description

technical field [0001] The invention belongs to an electric automatic control device, and relates to a novel electric control system for high and low pressure thin oil lubrication mainly used in the iron and steel industry and matched with the main motor of a steel rolling production line. Background technique [0002] Motor lubrication is mainly to lubricate the lubrication point of the steel rolling motor, reduce friction, protect the motor well, and prolong the life of the motor. It is an essential lubrication device in the steel rolling industry. For the lubrication electrical control system of multiple steel rolling motors running at the same time, the traditional method is to establish multiple PLC stations to realize multi-site monitoring thin oil lubrication stations, and each station is controlled by a PLC CPU. However, due to the high price of the CPU, the production cost is increased, and the multi-CPU communication signals are complicated and difficult to handle;...

Problems solved by technology

However, due to the high price of the CPU, the production cost is increased, and the multi-CPU communication signals are complicated and difficult to handle; on the other hand, the electrical control cabinet is equipped with a large number of operating and monitoring components such as indicator lights, knobs, buttons, and secondary instruments. , the wiring is complicated, and there are many hidden trouble points, which bring great inconvenience to the production, use and maintenance of the electrical control device; in addition, the traditional lubrication station sends the operating status and information to the upper computer through the switching value of the passive contact The signal is sent out in the form of point-to-point, and intermediate relays are required to isolate and connect the lines, which has certain limitations in the amount of information when evaluating cost performance
