Abstract
A coplanar multi-cylinder multi-grade combined compressor is provided with an eccentric spindle, a bearing on an eccentric wheel and a backward spring ensuring the reciprocating movement of pistons, wherein an ejection head with a hooked groove is arranged at the tail end of the piston rod to prevent the axial displacement of the eccentric spindle and ensure that the central lines of the piston bodies are overlapped with the centroid of the eccentric spindle; an external air inlet/outlet valve can be regulated according to different requirements; air cylinders are connected in parallel, embedded and combined with each other, and are in 180-degree symmetric arrangement with the eccentric spindle and the an eccentric wheel, so that the balance can be ensured without a balance disk equipped for the compressor; the backward spring completes a reciprocating cycle via the rotation of the eccentric spindle, coplanar multi-cylinder stage-by-stage compression and opening/closing of air intake/outtake film.
Description
Technical field
The present invention relates to machinery manufacturing technology field, a kind of isoplanar of specific finger multiple cylinder multiple level combination compressor.
Background technique
Compressor is that one is widely used, again the and general machinery equipment that play a significant role closely related with the every field of modern industry and life.Compressor can be used for refrigeration, motor, gas conveying, chemical process, machine-building and almost each need to carry or use the place of pressurized gas.Conventional air compressor is mainly piston type air compressor and screw air compressor at present, although these two kinds of compressors respectively have advantage, also all has certain deficiency.Such as, piston type air compressor is mainly to utilize rotatablely moving of bent axle, drives piston linear reciprocating motion to compress gas gas in the jar, the large and less stable of bearing shell friction noise; The engaging friction of screw compressor cylinder internal rotor, rotational velocity is fast, heating value is large, not only require the wear resistance of material very high, and also need when in use a large amount of cutting oils, so finally also need to carry out Oil-gas Separation, therefore cause that screw compressor energy consumption is high, cost is higher, the difficulty of complicated operation, maintenance and maintenance is larger.
Summary of the invention
The object of the invention is to design and manufacture the isoplanar multiple cylinder multiple level combination compressor of a kind of easy to operate, reliable operation, efficient energy-saving.
The present invention is achieved through the following technical solutions: the bearing on eccentric main axis and eccentric wheel and retracting spring ensure the reciprocatory motion of piston; Piston-rod end has the top of hook groove, prevents eccentric main axis axial displacement, ensures that the center line of each piston body overlaps with eccentric main axis barycenter; The air inlet and exhaust valve of external can regulate according to different demands; Cylinder block is in parallel with cylinder block inlays combination, same to eccentric main axis, and eccentric wheel is 180 ° and is symmetrical arranged that can realize need not be for compressor is equipped with Balance disc, to ensure balance; The rotation of eccentric main axis, isoplanar multi-cylinder compresses step by step, and by the keying of intake and exhaust diaphragm, retracting spring completes a reciprocation cycle.
Adopt this kind of device, in the time that driven by motor eccentric main axis rotates, make piston in cylinder, do reciprocatory motion by the retracting spring between the bearing on eccentric wheel and piston-rod end and top, avoid the use of crankshaft-and-connecting-rod, ensure the work of compressor continous-stable, reduce largely the noise that compressor produces, and can carry out multistage compression at the multiple cylinders of same plane device; Meanwhile, adopt this kind of device not only can improve the efficiency of compressor, and effectively reduce the volume of compressor, compressor weight is alleviated.
Brief description of the drawings
The invention will be further described by reference to the accompanying drawings;
Fig. 1 is the schematic diagram 1 of example of the present invention
Fig. 2 is the schematic diagram 2 of example of the present invention
Fig. 3 is the erection drawing of example of the present invention
Embodiment
See accompanying drawing 1,2,3, this is example of the present invention---isoplanar four cylinder combination compressors.It mainly comprises: the bearing A1 on eccentric wheel, and the bearing on eccentric wheel can avoid eccentric main axis to contact with the rigidity of piston rod top, reduces friction between the two; Compressor housing A2, compressor housing is the main support structure of compressor, for the bearing A1 on cylinder block A3, eccentric main axis A11, eccentric wheel, piston A7 provide installing space; Cylinder block A3, cylinder block can be any specification, is the main movement place of piston A7; Cylinder head A4, has screw to be connected with compression fuselage; Port A5, intake and exhaust diaphragm A6, piston A7, piston rod A8, retracting spring A9, for the reciprocatory motion of piston A7 provides certain driving force; Be with fluted piston-rod end top A10, being with fluted piston-rod end top main purpose is to prevent eccentric main axis axial displacement, ensures that the center line of each piston body overlaps with eccentric main axis barycenter; Eccentric main axis A11, eccentric main axis is connected with external motor, drives piston to do reciprocatory motion by the bearing on eccentric wheel; Piston ring A12, piston ring is to guarantee piston A7 and the seal of cylinder block A3 in the time coordinating; External air inlet and exhaust valve A13, the Main Function of air inlet and exhaust valve is to regulate according to the actual requirements intake and exhaust amount.
In the time that this example is implemented, air inlet diaphragm A61 opens, and exhaust diaphragm A62 closes, and under the ordering about of retracting spring A9, air is inhaled in cylinder block A3 by inlet hole A51; Meanwhile, under the driving of external motor, eccentric main axis A11 setting in motion, by the bearing A1 on eccentric wheel and the drive with fluted piston-rod end top A10, piston A7 setting in motion.In the time that the volume of cylinder block A3 reaches maximum, air inlet diaphragm A61 closes, eccentric main axis A11 is under the driving of external motor, by the bearing A1 on eccentric wheel and the drive with fluted piston-rod end top A10, piston A7 starts the gas in cylinder block A3 to compress, until the volume of cylinder block A3 reaches minimum.Now, exhaust diaphragm A62 opens, gas after compressed is discharged by exhaust port A52, enter next cylinder by external air inlet and exhaust valve A13 and repeat above process, realize isoplanar multi-cylinder combination compression, the gas after the compression of isoplanar multi-cylinder also can external air inlet and exhaust valve A13 enters in next stage compressor and repeats above process, realizes multistage-combination compression, until meet or exceed needed pressure, compressed gas just starts application.
The air compression method uniqueness that the present invention adopts, can solve the shortcoming of existing various compressors, improves the efficiency of compressor.Not only can effectively make the volume of compressor reduce by the present invention, weight saving, realizes miniaturization, the portability of compressor, and easily manufactured saving material, cost-saving simultaneously.
