Pneumatic type reciprocating pump is a kind of pneumatic supercharger, belong to the new engine, is gradually in the 30 years of development, hydraulic pump piston and the cylinder piston by the piston rod of rigid connection of pneumatic supercharger piston ponent directly. Pneumatic supercharger and crankshaft engine and hydraulic pump bination of power saving is the difference between the hydraulic pump will be rotary motion into reciprocating motion of piston pump swash plate, and the crankshaft type internal bustion engine piston in reciprocating motion into rotary motion of the crank connecting rod mechanism. Pneumatic supercharger so low cost, simple structure, light weight, less number of parts, high efficiency and energy saving, etc. As a new engine, the old engine in the world today has been replaced by reciprocating pump in the practical application. First, by using thermodynamics, mathematics equation, momentum equation and the output pressure and flow rate characteristics of pneumatic supercharging system, the features of the movement of the actuator mathematical description, focuses on the output pressure and flow rate characteristics of pneumatic supercharging system, as the theoretical basis is provided for the development of pneumatic supercharger. Second, according to the system requirements specification and performance index, the basic structure parameters, the system principle, the actual situation and the control circuit, the design and calculation. Third, review the design of pneumatic supercharger, after review of the pneumatic supercharger concrete structure design. 氣動增壓器結構設計 III With pneumatic supercharger as design object, this paper analyzed in many aspects including pure theoretical analysis, project feasibility analysis and the establishment of the principle of hydraulic analysis, design structure and proofreading, and other aspects of the work principle of a prehensive system design. First of all, according to the performance of the system requirements, the system39。 Reciprocating motion.
