Technical field

The present invention relates to compressor field more particularly to a kind of permanent magnetic piston compressor and its working methods.

Background technique

Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system It is dirty.It is operated after compressing with piston to it, to row from the refrigerant gas of air intake duct sucking low-temp low-pressure by motor The refrigerant gas of high temperature and pressure is discharged in tracheae, provides power for refrigeration cycle.

Existing compressor type mainly has piston pressure, screw, centrifugal and linear etc..It is most heavy as refrigeration product The performance of the component part wanted, compressor has been largely fixed the refrigeration effect of product, service life, noise and vibration etc. Performance.Especially in the case where the current energy, environmental problem are increasingly severe, refrigeration device energy-saving is as national energy strategy One important component proposes more higher requirements to the working efficiency of compressor, needs real in terms of energy conservation and environmental protection Now further optimization.Inventors have found that existing refrigeration compressor all has that structure is complicated in varying degrees, especially It is the limitation for being driven motor technology, the larger situation of generally existing volume, but now with electronic chip, laser, radar Etc. technologies rapid development, micro- space cooling technology demand is more more and more urgent, needs to realize in terms of refrigerating plant micromation prominent It is broken.

Summary of the invention

For overcome the deficiencies in the prior art, the present invention provides a kind of permanent magnetic piston compressor and its working method, tool There is energy loss compared with the effect that small, structure is simple, dynamic component is few, is suitble to miniaturization and is miniaturized.

The present invention adopts the following technical solutions:

A kind of permanent magnetic piston compressor, including closed circular ring shape pipeline, are equipped in the circular ring shape pipeline and its inner wall The permanent magnet piston of fitting, the magnet exciting coil of circular ring shape pipeline outer wall multiple groups independent control uniformly at intervals；Encouraging after energization Magnetic coil can generate the magnetic field attracted permanent magnet piston, so that permanent magnet piston is close to the sliding of circular ring shape inner wall of the pipe, to circle Fluid in circulating line is compressed.

Further, the circular ring shape Pipe installing gate, when closed shutter, can completely cut off in the circular ring shape pipeline of its two sides Portion's fluid allows permanent magnet piston to pass through when unlatching.

Further, the gate side is equipped with air intake valve, and the other side is equipped with outlet valve.

It further, can be gas or gas-liquid mixed two phase flow by the fluid that air intake valve enters circular ring shape pipeline Body.

Further, the both ends of the permanent magnet piston have magnetic pole.

Further, the rotation direction of the magnet exciting coil is identical.

A kind of working method of permanent magnetic piston compressor are as follows: when permanent magnet piston is in one side position P of gate, gate is closed It closes, air intake valve is opened, and drain tap is closed, and permanent magnet piston is under magnetic drive, and fluid in front is compressed, Fluid pressure It increases, rear space volume increases, fluid pressure drop, continues from air intake valve air-breathing；

Meanwhile the fluid in front of permanent magnet piston is all being compressed, and when close to gate other side symmetric position P ', exhaust valve Door is opened, and compression fluid is flowed out from drain tap；When permanent magnet piston reaches the position P ', drain tap is closed, and air intake valve is same When close, gate opening, when permanent magnet piston returns to position P by gate, closing gate, complete one cycle.

Further, the magnetic drive process of permanent magnet piston are as follows: the magnet exciting coil in front of permanent magnet piston is powered, and produces The raw magnetic field attracted permanent magnet piston, attracts permanent magnet piston to enter inside it from magnet exciting coil one end；Close to magnet exciting coil The other end, when magnetic field force is converted into repulsive force, magnet exciting coil power-off, another group of front coil is powered.

Compared with prior art, the beneficial effects of the present invention are:

(1) permanent magnet piston of the invention can slide under the driving of magnet exciting coil in circular ring shape pipeline, to annulus Fluid in shape pipeline is compressed, and the low-pressure fluid for flowing into circular ring shape pipeline from air intake valve is compressed into high-pressure fluid from row Air valve discharge, plays the role of compressor；Its dynamic component is less, is suitble to miniaturization and micromation.

(2) power source of permanent magnet piston of the present invention be powered magnet exciting coil, and permanent magnet piston can only one-way movement, Energy loss is smaller, more high-efficient than reciprocating piston.
