Description
Technical field
The invention belongs to the technical field of positive displacement compressor, refer in particular to a kind of radial multi-cylinder synchronous revolving compressor.
Background technique
At present, though general reciprocating piston air compressor is of a great variety, structure is similar, be exactly that motor is by the bent axle outputting power, come the pressurized gas acting by the to-and-fro motion in cylinder of connecting rod driven plunger, to produce pressurized air, still there are many defectives in this compressor: the one, and the mode that cylinder of compressor and frame all adopt mutual positioning instant not move, the compressor of this structure is unfavorable for the heat radiation of compresser cylinder; Two is that the motor of a compressor only drives one or two pistons work by connecting rod, and its power is little, efficient is low; The 3rd, compression stroke is longer, and power consumption is big, and cylinder is subjected to lateral force bigger, and eccentric mass is big, cause vibrating or the amplitude that resonates big, the noise of compressor is big, working life is short; The 4th, because the lateral force that bent axle and piston are subjected to is bigger, piston ring is easy to wear, causes the sealability variation.For above-mentioned reasons, when the compressor design selection, also higher to the requirement of material.
Summary of the invention
The purpose of this invention is to provide a kind of good airproof performance, noise is little, heat radiation is good, mechanical efficiency is high, the radial multi-cylinder synchronous revolving compressor not high to material requirements.
The object of the present invention is achieved like this:
Radial multi-cylinder synchronous revolving compressor, comprise by the bearing of the bent axle of driven by motor, the cylinder of forming cylinder body and cylinder cap, support bent axle, frame, the piston that in cylinder body, moves reciprocatingly, it is characterized in that: be provided with the circumferentially uniform above bidirectional piston and the cylinder body supporting of a cover of rotating center separately that have on the bent axle of driven by motor and perpendicular to the same plane of bent axle with it, bent axle, cylinder body, piston can rotate synchronously along rotating center separately, and cylinder cap and/or piston head are provided with inlet and outlet mouth and inlet and outlet valve.
The inlet and outlet mouth that on above-mentioned cylinder cap, is provided with, by be arranged on passage on cylinder cap and the cylinder introduce behind the center hole on the frame be arranged on frame on air outlet adapter be communicated with.
Be provided with self-compensating seal arrangement in the inboard of above-mentioned air outlet adapter.
Above-mentioned bidirectional piston is the disjunctor piston of a symmetry, and the middle part of piston body is installed on the eccentric journal with rotating center separately on the bent axle, and every cover bidirectional piston has identical throw of eccentric with respect to crankshaft center.
Above-mentioned bidirectional piston and the cylinder body supporting with it have two covers, and two cover bidirectional pistons and the cylinder body supporting with it are installed in respectively on the bent axle mutual vertically, and two eccentric journal centers are with respect to 180 ° of symmetries of crankshaft center.
Around its rotating center rotation separately, the ratio of its rotating speed is 2: 1 respectively for above-mentioned bent axle and cylinder body.
Above-mentioned cylinder body is integrated type or modular structure.
Outer surface at above-mentioned cylinder body is provided with radiating fin.
Above-mentioned frame is provided with the defensive guard shield of rotary cylinder-block.
The outstanding compared to existing technology advantage of the present invention is:
1, volume is little, mechanical efficiency is high: the present invention adopt with compressor crank shaft on same vertical plane in bidirectional piston and cylinder body more than the cover are installed, make motor under same power consumption situation, drive the Piston Compression gas acting more than two or four, make piston and cylinder body concentrated relatively, the overall volume of compressor is little, the mechanical efficiency height;
2, heat radiation is good: the present invention adopt the cylinder body rotation and from crankshaft cavity to piston body in air inlet, derive the mode of gas from cylinder head and cylinder, can be in intake process to bent axle, piston rod and piston body heat radiation, the cylinder body of rotation can dispel the heat to cylinder, cylinder cap again, make the integral heat sink of compressor effective, can reduce selection standard the compressor manufactured materials;
3, noise is low: the present invention is owing to adopt bidirectional piston and cylinder body circumferentially being symmetrical arranged along bent axle, balance because the bump that the straight line motion of piston causes the lateral force of cylinder body, and because compression stroke is shorter, make that the pulsation time of gas in cylinder body is short, the vibrations time is short, low in energy consumption, and then make the noise of compressor lower;
4, good airproof performance: the present invention since bidirectional piston and cylinder body in compression process balance lateral force, make the operating steadily of piston body, light with the friction of cylinder inner wall, wear of piston-rings is few, good airproof performance.
