Abstract
The design of the current oil dehydration trailer, combined with the latest research achievements of the current field of science and technology, the design of the lubricating oil dehydration is a more advanced technology, reliable performance, high degree of automation of the cleaning Trailer control system. The design of the guiding ideology based on the improvement of lubricating oil purification trailer system reliability, safety and efficiency. This system uses PLC technology also has certain reference significance for other control system.
Aiming at oil dehydration Trailer control problems in the system, the PLC programmable controller is applied to the lubricating oil purification Trailer control system, and a more in-depth studies.
This paper expounds the trailer system lubricating oil dewatering and purification of PLC control of some of the basic ideas and methods, and emphatically introduces the working characteristic and operation principle of PLC, the main function module and application of Emerson EC20-2012BRA programmable controller is also presented.
Keywords: oil dehydration trailer control syst
