Embodiment 1

[0030] like figure 1 As shown, the multi-cascade twin-cylinder linear compressor of this embodiment is the basic structure.

[0031] The connection relationship is: the motor stator 11 is a hollow structure, the motor mover 12 is inserted into it, and the motor mover 12 makes a reciprocating linear motion; the double-chamber compression cylinder is located on both sides of the linear motor, the cylinder body 4 is a hollow structure, and both ends pass through the cylinder head 2 Realize the sealing of the cylinder; the double-sided piston 7 is inserted into the cylinder body 4, and the cylinder is divided into a primary compression cavity and a secondary compression cavity (it is stipulated that the compression cavity close to the linear motor side is a secondary compression cavity, and the opposite side is a primary compression cavity); The cylinder head 2 forming the primary compression chamber is provided with a primary intake valve 1 and the primary exhaust valve 3, and th...

Embodiment 2

[0036] like figure 2 As shown, the parallel type of the multi-cascade two-cylinder linear compressor of this embodiment. It consists of two multi-cascade double-cylinder linear compressors connected in parallel (the upper multi-cascade double-cylinder linear compressor is called the previous multi-cascade double-cylinder linear compressor, and the lower multi-cascade double-cylinder linear compressor The compressor becomes the latter multi-cascade twin-cylinder linear compressor).

[0037]The connection relationship is: connect all the two-stage exhaust valves 10 of the previous multi-cascade two-cylinder linear compressor to the first-stage intake valves 3 on the same side of the latter multi-cascade two-cylinder linear compressor through the interstage connection Tube 5 is connected. The connection relationship of other components is the same as that in Embodiment 1.

Abstract

The invention relates to a multi-cascaded double-cylinder linear compressor, and belongs to the field of energy power. The multi-cascaded double-cylinder linear compressor comprises double-cavity compression cylinders, a linear motor and cascading pipes. Each cylinder is composed of a cylinder cover and a cylinder body and is divided by a double-sided piston into two air cavities (a first-stage compression cavity and a second-stage compression cavity), wherein the two air cavities communicate with each other through the corresponding cascading pipe; and the double-sided piston is driven by thelinear motor to reciprocate to continuously change the volumes of the two air cavities, so that first-stage compression and second-stage compression are completed. Series connection and parallel connection of the multi-cascaded double-cylinder linear compressor are completed through different connection manners of the cascading pipes, and thus, variable-pressure ratio and variable-displacement output is achieved. According to the multi-cascaded double-cylinder linear compressor, the structure of the high-pressure compressor is simplified; and a multi-cascaded reciprocating-type linear compressor system is a resonant system, so that the energy utilization rate is increased.

Description

technical field [0001] The invention relates to a multi-cascade double-cylinder linear compressor, which belongs to the field of energy and power. Background technique [0002] In recent years, high-pressure compressors have been used more and more widely in national economic construction and national defense construction. Due to the large difference between the normal pressure of the working fluid and the required output pressure, the compression ratio is large. In order to better save energy and improve heat dissipation, high-pressure compressors generally adopt the form of multi-stage compression. At present, multi-stage compressors are mainly divided into centrifugal and reciprocating compressors. [0003] Among them, the multi-stage reciprocating compressor, which is widely used, drives the crankshaft to rotate through the motor or engine, and the crankshaft actuates one or more pistons in one or more cylinders to realize reciprocating motion. The overall volume of the...
