The Research Of Property And Application Over The Pump Under Constant Power And Constant Pressure

With the rapid decrease of resource, the high efficiency and energy-saving product has been more and more popular. The constant power and constant pressure pump has just been developed under this background. The purpose of this dissertation is studying the property of the pump and put forward a doable scheme for the possible problem. The whole dissertation will be composed of three parts. In the first place, according to the academic analysis, we can get the static response curve; For the dynamic property, we can firstly calculate the mathematical model of the system, and then obtain the dynamic response curve by using the simulating software—MATLAB. According to the analysis of static and dynamic curve, it can be sure that the stability of the pump is ascendant. In the second place, by using advanced experimentation and apparatus, we can make an experiment on the diversified property of the pump, according to experiment, we can get a great deal of data, and then obtain the experiment curve. With the comparison between experiment curve and simulating curve, we can testify fatherly that the pump is steady and ascendant. When we make the experiment, we also choose different parameter of the pump in order to make sure that the pump can have a better property. In the third place, after the academic and experiment investigation, we apply the new-style pump to the practice. In my dissertation, I designed a new hydraulic system by using this new-style pump, and then compared with the customary hydraulic system, analyzed the advantage of the new-style pump system especially in the energy-saving part. In conclusion, according to the research of this dissertation, we can have all-around understandability to this new-style pump especially in the high efficiency and energy-saving part.
