Study on control system of grease lubrication

The special lubrication system is needed to ensure normal operation and prolong service life of the large machinery. In traditional centralized lubrication system, lubrication faults are easy to occur for many shortcomings such as poor generality, low measurement precision, inaccurate diagnosis of leakage and blockage. The practical systems can not meet the requirements of a reasonable lubrication. This paper studies structure planning of the lubrication system, technology of quantitative lubrication, online monitoring of pressure and temperature. A centralized lubrication system with distributed structure is put forward, which is composed of monitoring master, main control cabinet and lubricating terminals. The point-by-point lubrication and detection can be achieved in this system. The detection methods of oil pressure, flow and temperature are studied and reliable digital detection schemes are proposed. The developed system has been successfully applied in industrial field and the lubrication performance gets obvious improvement.
