Problems solved by technology

[0004] 1. Although the structure of the natural air cooling heat dissipation design adopted by it is simple, its heat dissipation effect is not ideal
[0005] 2. It greatly improves its volumetric clearance efficiency by relying on the ultra-long piston stroke, forming a working state with an ultra-high working compression ratio. However, the piston of this model has not been fully utilized to withstand the exhaust gas The characteristics and favorable conditions of the valve flushing out of the cylinder can further reduce the remaining clearance volume in its structural matching shape, and give full play to the possibility of increasing the working compression ratio to a greater extent
Because the existing machining conditions are often the main reason restricting the design of the cylinder super long size

Embodiment Construction

[0027] Depend on figure 1 Shown:

[0028] The stator winding 6 and the mover part 7 in the present invention form an AC linear motor drive mechanism, and the alternating current drives the mover part 7 to move horizontally through the horizontally moving magnetic field generated on the stator winding 6 . And the mover part 7 impels the pistons 5 at both ends to do compression work and suction work respectively through the universal joints 15 at the two ends of the link rod 12 . The main function of the limit spring 3 is to position the exhaust valve plate 11 . The high-pressure air chamber 17 is formed by the end position of the cylinder 10 and the cylinder head 1 .

[0029] When the piston 5 at both ends is moving right: the piston 5 in the left cylinder 10 is just sucking air from the low-pressure air chamber 8 through the suction valve 4 opened in the middle of it (the suction method is a downstream type), while Piston 5 in the right side cylinder 10 is rushing out of cy...

Abstract

A piston-type compressor with ultrahigh compression ratio features that a linear motor is used as its power source and the power of motor is only related to the diameter of piston (output power), but not to the stroke of piston. Its compression ratio can be increase by increasing piston stroke as long as possibe.

Description

Technical field: [0001] The invention relates to a special compressor technology with super long stroke and low reciprocating frequency. Background technique: [0002] The driving mode of the existing piston compressor is mainly completed by a rotary motor or a linear motor. [0003] CN 86104569A discloses a high-compression-ratio machine driven by a linear motor, in which the power of the motor in super-long stroke and low-frequency operation has nothing to do with the stroke of the piston, because it breaks through the existence of the conventional compressor machine: the diameter of the piston 1. There is an "optimal interlocking relationship" between the piston stroke and the motor power, that is, when the piston diameter and motor power related to the output are determined, the piston stroke cannot be lengthened. Its disadvantages are: [0004] 1. Although the structure of the air natural cooling heat dissipation design adopted by it is simple, its heat dissipation ef...
