Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , The structure of the double opposed piston compressor of the present invention includes a compressor crankshaft 5, an outer connecting rod 4, an inner connecting rod 6, a cylinder liner 7, an inner piston 2, an outer piston 1, a piston firmware 3 and an air valve 8. The compressor crankshaft 5 is installed in the casing, and the two ends of the compressor crankshaft 5 are equipped with rolling bearings, and the rolling bearings are installed in the bearing housing. The crank in the middle section of the crankshaft is connected to the inner connecting rod 6, such as figure 2 As shown, the inner connecting rod 6 is connected with the inner piston 2 through a piston pin. see image 3 , in order to make the outer connecting rod 4 and the outer piston 1 fixedly connected together, a piston fastener 3 similar to a piston pin is designed as...

Abstract

The invention discloses an opposite-opposition piston compressor structure. The structure comprises a compressor crankshaft connected with an external drive motor through a coupler, two air cylindersof the same structure are arranged on the two sides of the compressor crankshaft, an outer piston and an inner piston which are oppositely arranged are arranged in each air cylinder, a crank with thelarge crank throw radius on the compressor crankshaft is connected with the inner pistons through inner connecting rods, a crank with the small crank throw on the compressor crankshaft is connected with the outer pistons through outer connecting rods, the compressor crankshaft rotates to drive the inner connecting rods and the outer connecting rods to do rotation motion on the cranks, the inner connecting rods drive the inner pistons to do circular reciprocation motion in the air cylinders, the outer connecting rods drive the outer pistons to do circular reciprocating motion in the air cylinders, the air cylinders are provided with air valves, and the air valves are in seal connection with the air cylinders. Through dual air cylinders, work of traditional four air cylinders can be finished, layout is simple, the weight is small, parts are few, the space use rate is high, the stroke of a single piston can be shortened, and the total stroke can be prolonged.

Description

technical field [0001] The invention relates to the field of compressor design, in particular to a structure of a double opposed piston compressor. Background technique [0002] Piston compressor is a kind of positive displacement compressor. Through the cylinder, air valve and piston reciprocating in the cylinder, the working volume is continuously changed to work. It has a wide pressure range and the exhaust pressure is basically not affected. Due to the advantages of limited flow rate, wide range of exhaust volume and high thermal efficiency, it is widely used in various industrial occasions. [0003] Compressors are divided into vertical compressors and horizontal compressors according to the relative positional relationship between the centerline of the cylinder and the ground plane. The horizontal compressors are divided into opposed or counter-moving according to the position of the cylinder relative to the fuselage. The common structural feature of this type of comp...
