Abstract
At full speed development give aviation support oil work and propose high specification requirement civil aviation of China cause, The plane supports the oil and automobile to refuel and differ widely, it requires supporting the pressure of the oil to be steady, The velocity of flow is moderate; Especially adopt the generous introduction that the pipeline of long distance sent the oil and new model, Require aviation to support the oil to adapt to more different situations. How to satisfy the condition of a pressure of fuel tank of plane, it is stable, swift to accomplish, Safe, how accomplish and get up rapidly, how pump a kind one prevent water from hit, how attain in time accurate, the safety supplies sail oil fair and softly, is in the sail oil to swallow to vomit to have great capacity, provide oil discharge to change particularly under great condition more and so much satisfy these request, This is that boat oil supplies the question that is designed and must be considered systematically. programmable controller used programmable memory, used to implement logic in their internal storage operations, sequence control, timing, counting and arithmetic operations, such as operating instructions, and through digital and analog input and output, the control of various types of machinery or production processes. Utilizing the converter, PID regulator , an one-chip computer, PLC waits for the organic integration of the device, forms the control system, regulate the flow of output of the oil pump, Realize that constant voltage supports the oil. Adopt and programmer and control technology realize modern equipments constant voltage support the oil converter, etc. controller．It is a inexorable trend of oil domain technological innovation of boat.
Keywords PLC ; The converter ; Constant voltage ; Water is hit
