Description
Technical field
The utility model relates to a kind of air compressor, especially a kind of small-sized piston formula air compressor, specifically a kind of multi-piston type air compressor.
Background technique
As everyone knows, compressor can be divided into piston type, screw type, blade type and spiral etc. according to the difference of working method, and piston compressor relatively simply is widely used owing to structure, and the air compressor that uses in the market is the piston type air compressor of single cylinder crank-connecting rod transmission mostly, its noise is bigger, and cost is also than higher, simultaneously because wearing and tearing are bigger, so its life-span is shorter, and efficient is also lower.Though industrial the multi-cylinder air compressor arranged also, its structure also be unable to do without the structure that crankshaft-link rod drives reciprocating motion of the pistons, exists noise big equally, temperature rise, cost problem of higher.
Summary of the invention
The purpose of this utility model is that the noise that exists at existing piston formula compressor is big, the cost height, and inefficient problem, it is long to design a kind of life-span, and noise is low, efficiently, multi-piston type air compressor cheaply.
The technical solution of the utility model is:
A kind of multi-piston type air compressor, it comprises the power plant 1 that rotating power can be provided, it is characterized in that being equipped with the swash plate 2 of synchronous rotation on the output shaft of described power plant 1, bearing 13 is installed on swash plate 2, backing plate 3 is installed on the bearing 13 with the gradient identical with swash plate 2; Backing plate 3 offsets with more than one plunger 4, cylinder body 7 is provided with the cylinder 16 that equates with plunger 4 quantity, each plunger 4 is positioned on cylinder 16 end outward spring 12 is installed, the end that plunger 4 is arranged in cylinder 16 is connected with piston 5, piston 5 is provided with suction port 14, and suction port 14 is equipped with breather cheek valve 9 near on the end of exhaust cavity; In the outer end of cylinder body 7 end cap 11 is installed, between cylinder body 7 and end cap 11 dividing plate 8 is installed, be provided with relief opening 15 with each piston 5 corresponding position on the dividing plate 8, one-way exhaust valve 10 is installed on the relief opening 15, end cap 11 is provided with total relief opening 20.
Described breather cheek valve 9 is a leaf valve, and described one-way exhaust valve 10 also is a leaf valve.
In described cylinder 16 cylinder sleeve 6 is installed, piston 5 is installed in the cylinder sleeve 6.
Described plunger 4 is arranged in cylinder 16 outer ends and is positioned at the guide ledges 17 of projection on cylinder body 7 close air aspiration cavity one end end faces, and plunger bushing 18 is installed in guide ledges 17.
The inclined angle alpha of described swash plate 2 is 45～85 degree, and its best angle is about 75 degree.
Cylinder body 7 is provided with the cylinder 16 more than three or three.
Described power source 1 is a kind of in motor, petrol engine, diesel engine or the natural gas engine, directly installs on their output shaft in the swash plate 1, also can be installed in the output shaft of the speed change gear that links to each other with them.
The beneficial effects of the utility model:
(this is owing to reduced the unbalanced friction of piston ring in the past) compared and had the long-life to the utility model with existing similar air compressor, noise is low, efficient is high and advantage cheaply.
The utility model adopts the swash plate driving structure, and the power of power source (comprising various motors and gasoline, diesel oil, natural gas engine) output is converted to the straight reciprocating motion of plunger by the rotation of swash plate with circular movement, the quantity N of plunger 〉=1.In the straight reciprocating motion of plunger, piston is too along with plunger carries out straight reciprocating motion together, in the straight reciprocating motion of piston, two intake and exhaust reeds are along with the to-and-fro motion of piston opened and closed according to certain cycle, thereby realize intake and exhaust and air compression.Under the situation that power (comprising various motors and gasoline, diesel oil, natural gas engine) fortune circles, N piston all intactly carried out intake and exhaust, whenever circle, can realize N intake and exhaust, whenever circle with respect to the single cylinder piston type air compressor and only to do intake and exhaust, the efficient of many Piston Air Compressor is greatly improved.And make the suction and discharge acting of each piston obtain a balance, the piston that promptly has other plunger when doing the exhaust merit is being done air-breathing merit, makes the output power of motor obtain maximum performance, has improved exhaust efficiency greatly.Owing to adopt inclined disc type transmission, thoroughly changed the reciprocating form of oilless air compressor beat in the past simultaneously, made piston only do straight reciprocating motion, reduced unbalanced friction, improved efficient and life-span in cylinder interior.Inclined disc type in addition transmission helps reducing noise, reduces the requirement to power source, and safety coefficient is higher, and volume is littler, and exhaust efficiency is than the single cylinder piston type air compressor height with discharge capacity.
The utlity model has wide accommodation, advantage simple in structure, easily manufactured, it both had been applicable to light duty compressor, be applicable to again micro-compressor and in, big capacity compressors.
