Air compressor

Abstract

The invention discloses an air compressor. The air compressor comprises a machine body, wherein at least three axial holes are formed in the machine body, a left end cover is fixedly arranged on the left side of the machine body, and a right machine shell is fixedly arranged on the right side of the machine body; a piston body is slidably connected in each axial hole, and the right side of each piston body is provided with a piston rod in an extending mode; pumping assemblies corresponding to the axial holes in one-to-one correspondence are arranged in the left end cover; the right side of themachine body is provided with a first concave spherical groove, and the right machine shell is provided with a second concave spherical groove; oil holes are formed in the machine body; the side surface of the right machine shell is provided with a P port and a T port; a rotating block is rotationally connected in the right machine shell, a rotating groove is formed in the left end of the rotating block in the direction perpendicular to the inclined plane, and a flow distribution shaft is rotationally connected in the rotating groove; and the lateral surface of the outer circumference of theflow distribution shaft is provided with a convex edge in the radial direction, and the right end of each piston rod is hinged to the convex edge through a ball. The air compressor has the advantagesthat the structure is compact, the overall design is highly integrated, a motor is not needed, electric instability factors are avoided, the air compressor can work for a long time, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to an air compressor. Background technique [0002] The reciprocating air compressors currently used in the market are mainly double-piston reciprocating air compressors. Although the double-plunger reciprocating air compressor can achieve continuous pressure output, the output pressure is zero at the moment of reversing, which makes the output pressure pulsate. It cannot be used in some occasions that require constant pressure. For example, the application number is: 201810479411.1. The hydraulically driven reciprocating air compressor needs to stop after the piston moves in place when it is working, and wait for the external reversing valve to change direction before moving in the reverse direction, which makes the output pressure pulsate, and the external reversing valve so The volume is large and the cost is high; the external reversing valve has complex oil...

Although the double-plunger reciprocating air compressor can achieve continuous pressure output, the output pressure is zero at the moment of reversing, which makes the output pressure pulsate. It cannot be used in some occasions that require constant pressure. For example, the application number is: 201810479411.1. The hydraulically driven reciprocating air compressor needs to stop after the piston moves in place when it is working, and wait for the external reversing valve to change direction before moving in the reverse direction, which makes the output pressure pulsate, and the external reversing valve so Large size and high cost; the external reversing valve has complex oil circuit, complex control, and complex structure. When a fault occurs, it is not only difficult to troubleshoot the problem, but also inconvenient to maintain
