The Pumpage Of Concrete Measures And Control Technical Research In Real Time

With the development at full speed of national economy and Quickening of the urbanization process, the consumption of the concrete increases by a large margin and the demand for the concrete pump car increases rapidly too. People need to measure the measurement system of concrete displacement urgently In the reality of the goods concrete is used. Real-time pump sending can bring convenience to measure technology to both sides, guarantee the construction quality at the same time.The pump sending without complicated supplies measures the system at china at present foreign relevant research are less too.Only Japan has done the studying of a certain degree to the pump metering method of the oscillating piston. But it is not enough to measure precision actually.This text has introduced three kinds of new metering methods of pumpage of concrete. To their measurement principle , have done detailed exposition and comparison in each characteristic. Provide the result of the test of each kind of metering method and compare and analyse. The author considers adopting the third kind of measurement scheme finally, provide the third systematic design philosophy of hitting the scheme and realize the principle, software and hardware structure, provide the experimental result and analysis of performance finally.The thesis is divided into six chapters.Chapter one a part of the introduction, discuss the developing history, structure and operation principle of the concrete pump mainly, and future developing direction, introduced the selected title meaning of a subject and main research contents finally.Chapter two detailed theory of mechanics of rheology in the course of pump sending of introduction concrete, point out the change in the course of pump sending of each point pressure of pump sending and relevant characteristics, measure the systematic theoretical foundation of laying mechanics of design for pump sending.Chapter three is a key chapter of this text, recommend three kinds of new concrete pumps to measure the scheme, having explained the measurement principle of each scheme, realize the way, performance is compared, analysis of result of the test.Chapter four, have recommended adopting the pressure signal of pump sending to lead out the efficiency coefficient of real-time pump sending, realize the method that the concrete pump measures in real time.Chapter five have introduced realization of the concrete pump complete machine control technology and systematic emulation.Chapter six summarize copies of work that subject make in an all-round way, to study and use prospect not to is it expect to make further.
