Abstract: In view of the problems that lubricating failure frequently took place in traditional single-strand and double-strand lubrication system because of their unreasonable design,a design scheme of intelligent centralized lubrication system was put forward.General structure of the system was introduced,detection methods of oil pressure,flow and temperature parameter were studied,and reliable digital detection methods were proposed.Design of the lubricating terminal was discussed in details.The intelligent centralized lubrication system adopts distributed structure,has remote control function,and can achieve point-by-point lubrication and detection.The system has been successfully applied in industrial fields and can realize accurate timing and quantitative lubrication.
