| The lubricating condition of Spiral Conical Dispenser has been analyzed and introduced the advanced technology and the development of the theory of the centralized lubrication system as well in the paper. According to its characteristics of Spiral Conical Dispenser, the friction characteristics of the key friction areas have been analyzed. At the same time, the pressure, the temperature and its geometrical space limitations of the friction interfaces have been studied. Based on the above analysis, the automatic centralized lubrication and the on-line state monitoring system of Spiral Conical Dispenser has been developed. The design of the lubrication system includes the selections for the mode of the lubrication and the lubricant and the study of the major parameters and the properties of the lubricant. At the same time, the automatic centralized lubrication and on-line state monitoring system based on RS485 Bus and DSP has been developed for multi-Spiral Conical Dispensers. And its design works including: the characteristic parameter design of the automatic centralized lubrication system, the caculation for friction loss and the design of the total pressure, the design of the power for the electromotor, the design of the parameter for the hydraulic pipes and the total structure of the system; The lubrication system design inside Spiral Conical Dispenser including: the total theory, the key and the design for Dispensing Ring, the strength checkout of the hollow axle and etc; The design for the control sect of the automatic centralized lubrication system; The design for the on-line monitoring system including: the theory of the on-line state monitoring system and the software and hardware design for the on-line state monitoring system.The serial communication between the master computer and the slave computer has been analyzed and developed in the paper. Based on control technology and multithreading technology, a serial communication program has been developed. The function of real time communication and remote control between the master computer and DSP has been realized.The Automatic centralized lubrication and state monitoring system works in the bad conditions where there are many interference factors.AbstractHow to restrain the interference, raise the signal to noise ratio and improve the liability of the status monitoring and the precision of state monitoring for Spiral Conical Dispenser has been analyzed and researched in the paper.It is demonstrated by the operation and experiment on site that the system can control the work of lubrication automatically, decrease energy consumption and improve the management of production. It is easy to install and maintain and its operation is steady and reliable. The monitoring and controlling software has abundant functions and friendly interface, which is convenient to use. |
