[Abstract]:As an important part of the direct connection portable reciprocating piston compressor, the piston and connecting rod integrated compressor is widely used in the fields of family decoration, paint spray, beauty painting and so on. The main work of this paper is as follows:. AutoCAD is used to draw the parts and assembly drawings of the piston and connecting rod compressor, and the 3D drawing is obtained by using the engineering software Pro/E. In addition, the crank and connecting rod mechanism and the cylinder assembly of the compressor are introduced systematically with the help of the three-dimensional structure diagram. The structure and assembly relationship of compressor housing components. The axial displacement, radial displacement and rotation angle of piston body are obtained by analyzing the motion of piston and connecting rod integral compressor, and the axial direction of piston and connecting rod integral compressor is analyzed by MATLAB software. Radial kinematics. Using the traditional thermodynamic calculation method, the thermodynamic calculation formulas of the piston and connecting rod integral compressor are obtained. They can calculate the cylinder diameter, calculate the shaft power and select the driving machine. The balance weight and the moment of flywheel are designed, and the calculation program of flywheel moment is programmed by Visual Basic program. The fourth order Runge-Kutta method is used to solve the equations of gas flow differential equation and tongue spring valve motion differential equation. The displacement diagram and velocity diagram of the characteristic lift of tongue spring valve are drawn, and then the compression and expansion processes are calculated according to the adiabatic process. Finally, P-V diagram is drawn, and the indicated power of compressor is obtained by rectangular method. The process is realized by Visual Basic programming. 5) the dynamic finite element analysis of the whole working process of the exhaust tongue spring valve is carried out by using the large-scale nonlinear finite element software ABAQUS, including pre-processing, loading solution and post-processing, and the displacement diagram of the valve plate at the characteristic lift of the tongue spring valve is obtained. It is found that the maximum stress is at the root of the valve plate, the lift limiter has slight vibration, and the stress caused by the concave deformation of the valve head in the suction process is larger. This paper introduces the improved structure of the piston and connecting rod integrated compressor: the planar moving piston compressor, expounds the working principle of this type of compressor, and analyzes the leakage of the compressor by using the convergent nozzle model. Moreover, the structure type of improving compressor leakage and reducing friction and wear is put forward.
