Embodiment

[0036] In order to ensure the formation of a stable and reliable lubricating oil film for the large vibrating screen bearings, the present invention designs a PLC-based state monitoring and control system for large vibrating screens. The system works as follows:

[0037] (1) Real-time status monitoring and data recording operations.

[0038] Such as figure 1 As shown, the 4-20Ma signal of the sensor transmitter including temperature and pressure enters the PLC controller, and the data is converted into status information. The data can be displayed in real time by communicating the PLC controller with the host computer through industrial Ethernet. The PLC controller communicates with the serial port USB through the RS485 / RS232 cable, and can store the state information of the vibrating screen bearing in EXCEL form, and the timer in the PLC can store the current data every 20 minutes.

[0039] (2) Automatic control of oil temperature and pressure operation.

[0040] Such as ...

Abstract

The invention discloses a state monitoring control system for a large-scale vibrating screen, comprising a controller, relays, contactors, motors, sensors and transmitters thereof; the sensors are installed in a fuel tank of the vibrating screen for measuring corresponding data inside the fuel tank, and the data is output through the sensor transmitters; the controller is used to receive and process various data and perform corresponding control, the input end of the controller is connected to the output ends of the sensor transmitters, and the output end of the controller is connected to theinput ends of the relays; the output ends of the relays are connected with the input ends of the corresponding contactors; the output ends of the contactors are connected with the corresponding motors; and the motors are used for driving corresponding devices. The system can monitor the oil temperature and pressure data of the oil pool in real time, and realize real-time control of oil pool temperature and pressure according to these real-time monitoring data, forming a stable and effective lubricating oil film. The system is convenient to operate and high in intelligent degree, and the control precision is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical detection and relates to a state monitoring control system, in particular to a state monitoring control system for a large vibrating screen. Background technique [0002] Vibrating screens are widely used in mining, coal metallurgy and other industries, and are very common and important equipment in these industries. The vibrating screen is an elastically supported nonlinear vibrating system of a large eccentricity rotor bearing system, and the nonlinearity of the elastic vibration of the rolling bearing is very prominent. In large vibrating screens, the loss of bearings is particularly serious. [0003] There are many factors that affect bearing loss, the most important of which is lubrication. Whether the viscosity of lubricating oil can be maintained is the key to forming lubricating oil film, which is closely related to oil temperature and pressure. For now, the temperature of the oil po...
