Reciprocating air compressor for V type structure micro, minitype motivation

Abstract

The invention discloses a V-shaped reciprocating air compressor for mini or small power. The compressor is provided with a crankcase. Four equal cylinder blocks are arranged in a V shape on two V-shaped planes of the crankcase. A left cylinder cover and a right cylinder cover are arranged on the left cylinder block and the right cylinder block respectively; air valve components are arranged between the cylinder covers and the cylinder blocks; a shaft pin parallel with a main axis journal is arranged on the upside of a crank in the crankcase, a rocker is inserted in the shaft pin through a pin hole with a bush on the top, and the lower end of the rocker body is sleeved on a bell crank by a slide block component; connecting bar pin holes are arranged on two sides of the rocker; short shaft pins of the connecting bar of a plunger are hung over the pin holes on the two sides of the rocker. According to the lever rule, when the air compressor is under work, the plunger force applies two opposite moments of force to a hinge pin of the rocker, that is, the moment of reaction at the support of the hinge pin of the top rocker and the moment of driving force which pushes the rocker by sides of the slide block. The reaction at the support reduces the moment of driving force; therefore, the air compressor saves energy as much as over 20 percent.

Description

Technical field: [0001] The invention relates to an energy-saving V-shaped reciprocating piston air compressor, in particular to a V-shaped reciprocating piston air compressor for micro and small power with an energy-saving swing rod and a slider device. Background technique: [0002] In the past 10 years, a utility model patent has been applied for a miniature air pump with an energy-saving rod. The actual measurement of the third-generation prototype proved to have a 20% energy-saving effect, but due to some reasons, the design of the above-mentioned prototype has not been improved. The comprehensive consideration of the life and reliability of the air pump hinders the introduction of the patent to the technology market. [0003] In recent years, with the continuous improvement of the manufacturing process level of the screw compressor, its energy consumption index is gradually approaching that of the piston compressor, and because the advantages of the screw compressor ar...
