Static And Dynamic Characteristics Analysis And Simulation On Pneumatic Hydraulic Pump

This air operated pressure intensifier is a kind of Piston Engined Hydraulic Reciprocating Pump, it's a new strengthmachine in the nearly 30 years. In the system of the pump, Piston components is componented of the rigid directly linking of the cylinder piston and hydraulic piston, this struction needn't the crank rod which converts the reciprocating piston motion into rotational motion and the Wobble-body rotation which converts the rotary motion into the Reciprocating motion of piston pump in the internal combustion engine crankshaft. Thus, the system has Advantages of simple in structure, the small number of parts, light weight, low cost and high efficiency, wide range of fuels , can be recovered easily inertial and gravitational potential energy during the System's frequent starting and stopping and so on. As a special engine, the Piston Engined Hydraulic Reciprocating Pump Mainly to replace the crankshaft engine which is widely applied .This paper has served the pneumatic hydraulic pump as research subjects, and conducted a comprehensive and systematic study through Theoretical analysis, mathematical modeling and simulation, the program's accreditation, prototype development and other aspects of the system working mechanism . First, according to the requirements of the system performance, have carried out preliminary design on system principle, the control circuit, the basic structure parameters.Second, mathematical descriptions of output characteristics of the pressure, flow characteristic and kinematical characteristics of the high-pressure integrated component of valve-controlled pneumatic cylinder are developed based on the First Law of Thermodynamics, Continuity Equation and Momentum Equation. Output characteristics of the pressure, flow characteristic are emphatically analyzed through simulation study with MATLAB/SIMULINK software, which provide a theory foundation for the development of the pneumatic hydraulic pump.Finally, after the accreditation of the program,mapped out of the product drawings and developed the prototype.
