Description
Technical field:
The utility model relates to a kind of air compressor, relates in particular to the multistage multi-cylinder air compressor of a kind of combined type.
Background technique:
At present, known air compressor roughly can be divided into two classes by working principle; The first kind, positive displacement compressor, second class, speed mode compressor.The working principle of positive displacement compressor is the volume of pressurized gas, makes the density of gas molecule in the per unit volume increase to improve compressed-air actuated pressure; The working principle of speed mode compressor is to improve the movement velocity of gas molecule, and the kinetic energy that gas molecule is had is converted into the pressure energy of gas, thereby improves compressed-air actuated pressure.
Positive displacement compressor is directly to rely on to change the compressor that gas volume improves gas pressure.Basic model wherein such as reciprocating compressor, its compressing member are a piston, and be reciprocating in cylinder.
The velocity profile compressor is a kind of rotary type ' continuously ' airflow compressor.The blade of rotation accelerates the gas by it at a high speed therein, thereby speed can be converted into pressure.This transform portion occurs on the rotation blade, and part occurs on fixing Diffuser or the return channel baffle plate.Mostly its essence is doing a kind of exchange of kinetic energy electric energy to be converted to the air energy by mechanical energy, so that the power source that is fit to various applications and the use of all kinds of instrument to be provided.Two types above-mentioned machine has separately characteristic and defective, does not here give unnecessary details.
The model utility content:
In order to overcome the defective of existing two class air compressors, bring into play the characteristic of above-mentioned two class types better, use for reference their principle and feature, the utility model provides combined type multistage multi-cylinder air compressor, it is between a kind of new architecture structure between the two, can effectively utilize the feature of above-mentioned two class types, develop a kind of multistage multi-cylinder air compression new architecture of combined type, can enlarge the restriction of application and application conditions, and can in a compression chamber, develop many air flues of circulation compression according to the needs that use, the air compressor of multi cylinder.
The technical solution adopted in the utility model is:
From the basic functional principle of reciprocal compressor, know; To compress air and must satisfy three primary conditions namely; Will finish in the stroke of point from the low spot to the height, air-breathing---compression---exhaust has only and satisfies above-mentioned three conditions, could realize air is compressed.
This principle of the utility model utilizing just realizes the compression to air; Therefore, must be to two kinds of working methods of the multistage multi-cylinder air compressor of combined type of the present utility model, in 360 degree of circumference, distribute, define and divide, make it according to existing two types of working methods (reciprocating type, speed mode), work under the equal operating conditions that can satisfy separately of air compressor, the design of the multistage multi-cylinder air compressor of the utility model combined type can be set up.
At first, we are divided into the quartering to 360 degree circumference, every part 90 degree.(for the convenience of explaining, below with 360 the degree, be rewritten into following method: 0---360),---90---180---270---360 from 0; Wherein 0---the 180th, the operation interval of reciprocal compressor.Air-breathing from starting point 0 beginning, 90---180 compressions, when piston 360 the degree circumference circulation groove air flues in, from 0---during 90 motions, air flue and piston produce a suction force, the air that is positioned at 0 is sucked, when the piston operation moves to 90, side at the circumferential groove air flue at 90 places, the carrying path that connects of transverse intersection and be connected with second air flue is with it arranged, when air during by this path, understand some air flow that is inhaled into to " working area " (chamber volume), a part can be mobile in air flue along with piston, continues to move ahead to 180 directions.Owing to be to move in a circle, the appropriate location of corresponding piston has a slide plate also moving.Therefore, a sliding vane air valve (having piston function concurrently) is arranged also in synchronous acting,---270---360 directions move by 180, and the length of sliding vane air valve piston is; 180---270, when piston when motion---90, sliding vane air valve piston is from 270---360 motions from 0.Piston moves at 90 o'clock, slide plate just in time moves to 360, blocked inlet air pathway, the action function of slide plate converts the function of air valve and piston at this moment, along with piston continues to move ahead, slide plate will play the effect of air valve, and 0 suction port is blocked a period of time, at this moment the pressure that produces between piston and the sliding vane air valve makes the air in the working area compressed.When slide plate moves to 90, the position of the side of slide plate and air flue correspondence, have the fluid intake of a V-type, suck and compression being retained in two air between the piston, flow to the next stage air flue by the lateral transfer path, said process will be by from multiple, and this process is similar to the working state of reciprocal compressor and speed mode compressor, and correct saying so is a kind of between the working state between the two.It is the place of the definition foundation of the multistage multi-cylinder air compressor of the related combined type of the utility model.
When slide plate continues to move ahead when leaving 90, remaining portion of air between piston and the slide plate is in full closeding state in air flue.Along with piston and sliding vane air valve piston continue to move ahead, from 90---between 360, for piston and slide plate and the air that is closed, be to do parabolic motion, namely from 90 (low spots)---270 (high points) are to 360.Because centrifugal action, piston doing accelerated motion, has obtained certain energy with sliding vane air valve piston and the object that is closed.When the object that obtains certain energy is thrown to 0 from 270 (high points) from the height point, under the acting in conjunction of centrifugal force and the polished object body that obtains certain energy, when piston from 270---360 whens motion, the energy that produces can accelerate the air at 0 place to suck, and this moment, piston was from 0---and 0 has finished a cycle period.The motion that goes round and begins again, finish from air-breathing---the work of compression stage, this process is similar to the working state of speed mode compressor.These two kinds of working staties and process are the multistage multi-cylinder air compressors of the utility model combined type, the working state of first air flue and process.
Second air flue is just explained different piece according to the same work of the first air flue principle:
The definition of described combined type multi-staged air compressor; Multistage---many air flues need to have two air flues just can finish,---compression---job requirement of exhaust from air-breathing at least; Compound---reciprocating type+speed mode, (rotary type) can also be interpreted as the multi-cylinder air compressor that the circulation of combined type secondary is compressed.Therefore, the multistage multi-cylinder air compressor of the utility model combined type is the novel air compressor between a kind of working state between the two.
Wherein the work of first air flue has just only been finished; Air-breathing---compression, what second air flue was finished is; Air-breathing---exhaust, first air flue and the acting of second air flue just can be finished altogether, and---compression---is to one of exhaust complete workflow from air-breathing.Therefore, second air flue is pressed following principle work: when the piston of second air flue is origination data from 90; Piston is since 90---and 180 actings below will be divided into two and go on foot and to explain:
(1), along with the piston of beginning second air flue of acting, at first by with the pipeline of the horizontal UNICOM of first air flue, cooperate common acting with the piston of first air flue, (this moment, the piston of first air flue was to block on the suction port at 0 place) sucks the air of first air flue.Because the piston of two air flues is to do work the while, therefore the most air of first air flue is sucked, will flow to horizontal pipeline and " working area " storage by the lateral transfer path.From secondary circulation and after N time circulation, second air flue will be the working area that is stored in of first air flue, air sucks together and is indented out by second airway pressure.We it should be noted that this wherein has simultaneously, and the slide plate of first air flue is in the contribution of 90 o'clock the compression first time.Because the circulation from second circulation to later N time, the second air flue inhaled air is that first air flue adds the second air flue sum, increase along with the raising centrifugal force of rotating speed, inhaled air is also increasing gradually, centrifugal be and the pressure acting in conjunction of piston under, have that the part air is compressed to enter gas holder by second air flue.Other workflow is the same with first air flue, and no longer this gives unnecessary details,
(2), when the piston of " second air flue " moves to 270 from 90, the piston of " first air flue " is in 0 position, the piston of " second air flue " is in 270 position.Therefore when the piston of first air flue began secondary circular work, the piston of second air flue began inhaled air for the first time, and under the acting in conjunction of piston and sliding vane air valve piston, compressed back is discharged and delivered into gas holder.Piston and the slide plate position of two air flues of this moment all is in the position of satisfying operating conditions separately, the whole process of having finished---compression---exhaust air-breathing.Therefore can satisfy the basic work requirement of air compressor, the running that goes round and begins again converts electric energy to the air energy, has realized the job requirement of combined type multistage compression, multi cylinder.
