Description

A kind of concentric blade piston air pump

Technical field

The present invention relates to a kind of concentric blade piston air pump, it can be widely used in air pump field, electronic product production, Food and drink is canned, cleaning Tu fills the application such as equipment, textile printing, plastics subsidiary engine, automobile environment-protection and Novel model airplane.

Background technique

Air pump is that air or a kind of device from enclosure space addition air are excluded from an enclosure space, and air pump is at me Have very important effect in modern life, it is small to arrive toy model plane gas control, arrive large scale equipment gas circuit greatly, weight can be played The effect wanted, general air pump need that gas output is big or air pressure is high or vacuum is high, some pump classes can generate heat, and at this time enter cold air Water will be condensed into, so need oil water separator that water is made not enter pneumatic equipment, and the vortex pump that high pressure pressure-vaccum is dual-purpose, make With more convenient, and between the inner wall and rotor of the eccentric blade class air pump of profession be crescent moon space, the volume of each gas chamber with The rotation of rotor and change, take out that pressure effect is all good, being not required to of another rotary volume variation lubricates lobe pump without abrasion, Its structure type is evolved by Roots blower, but without suction capacity, and is changed rotor clearance and be can satisfy wider make Use range.So all kinds of pumps, with the embodiment of its work values and the expansion of use scope, the work problem of air pump is also put Greatly, electromagnetic type strength is small needs gate valve, and structure is complicated easily blocks easy to wear for vane type eccentric vane, and diaphragm type and piston type are easily sent out Heat, it is low that turbine type tortoise pumps air pressure, and Roots vaccum pump is only used as booster pump to use.

Summary of the invention

Air pump needs very high air-tightness compared to liquid pump, does not have gravity to generate centrifugation when carrying out gas transfer and makees With should there is the variation of capacity to seal again moving component, be difficult to accomplish continuous gas when improving axle speed during operation Close compression, using circumference as cavity, is gas chamber every being existed with two blades using blade or piston shaft then concentric blade piston air pump Certain one mutually changed during continuous rotation is dynamic, each other piston and air chamber sealing every or a thickening vane-piston In continuous rotary course, can open stifled point with control is air chamber sealing every passing round to piston, complete continuous rotation gas Compression.Mutual certain the one of two groups of blades is dynamic in circumferential cavity body, wherein first pair of blade positioning, second pair of blade rotation half Zhou Houyu first to it is to be collided when slowly to positioning, first pair of blade starts half revolution, then slowly to positioning, two groups of blade phases Pair another group of rotation of one group of positioning, i.e., the continuous compression gas that a certain one dynamic direction rotates, and control fixed or dynamic machine Structure is that the congruent triangles of two rotations are staggered 30 ° of positive antipositions, stirs a swing rod with three angles of a triangle, swing rod Length is less than the half of triangle contour, and 15 ° of triangle rotating corresponding swing rods rotate 150 ° or so, that is, drive one group of leaf Piece rotates 150 °, is then slowly slided with the length direction that the side of triangle is attached to swing rod, and triangle rotates 45 ° with side patch swing rod Left and right, corresponding swing rod rotate 30 °, i.e. one group of piston is slowly to positioning, then 60 ° of triangle rotating corresponding blade rotations 180 °, within 45 ° of times of triangle control positioning, another triangle completes 15 ° of rotation individually 15 °, two three of positioning again Angular to position 15 ° together, positioning is opposite here, and having slowly to rotate has slow compression, due to stirring for triangle Limiting axle speed is middle low speed.It is dependent on certain one dynamic structural principle, circumferential vanes structure is carried out to simplify available height Axle speed air pump blocks up point with bulged blading as piston with the dynamic that triangle stirs control blade construction, can simplify for Controlling the scarce ball of band with speed gear is stifled point, and band lacks remaining sealing to pass through when piston rotation, speed be band lack with Keep synchronous when piston is staggered as far as possible, and the multiple of speed is to correspond to the number of piston, the air-tightness for simplifying high speed air pump does not have The good but high speed of the air-tightness for having triangle to stir can improve air-tightness.
