The compressor and hollow shafts are provided with a motor whose two ends can be disassembled and in a half-closed state, and the pistons and the swing cylinder body are arranged on the same eccentric shaft and rotate simultaneously. The utility model has the advantages of simple structure, high efficiency of gas transmission, good effect of energy saving, and convenient maintenance.

Description

Semi-sealed double rotary refrigeation compressor

The utility model relates to a kind of semiclosed pair of Rotary Refrigerate Compressor that is used on freezing and the air-conditioning equipment.

Raising and improvement along with people's life, food deposit and living environment all requires good condition, refrigerator, refrigerator, air conditioner have been the freezing and air-conditioning equipment that extensively adopts for now, compressor is absolutely necessary on these equipment, and mostly present employed compressor is that employing is external, not only complex structure, and price is more expensive, and this gives production undoubtedly and uses and brought big economic burden.

The purpose of this utility model just provides a kind ofly to be had simple in structurely, and cost is low, and a kind of semiclosed pair of good Rotary Refrigerate Compressor of using effect.

The utility model is realized by following technical measures, on the basis of existing refrigeration compressor, reasonably improves, adopt compressor and the shared eccentric shaft of motor, remove oil pump, replace with getting rid of compression ring, by the centrifugal force in the eccentric shaft high speed rotary, the pressure reduction in two chambeies about causing, eccentric shaft are hollow shaft, and the body two ends are provided with detachable end, form semi-closed state, its body inner carrier is contained on the hollow shaft with the revolution cylinder body, and rotation synchronously forms two rotary types.

The utility model is that the science of existing compressor arrangement is improved, and is novel, unique, use and easy to maintenance, and cost is low, gas transmission efficient height, good energy-conserving effect.

Below in conjunction with accompanying drawing structure of the present utility model and working condition are elaborated.

Fig. 1 is the utility model structure sectional view.

Fig. 2 is the utility model fundamental diagram.

Fig. 3 is the utility model mechanical mechanism schematic diagram.

By shown in Figure 1, the utility model is by oil groove base plate 1, left end cap 2, piston 3, eccentric shaft 4, oil sucting valve 5, revolution cylinder body 6, body 7, outlet valve 8, terminal box 9, motor 10, get rid of compression ring 11, right end cap 12, spill port 13, oil-sucking hole 14, radiating fin (sheet) 15 constitutes, compressor eccentric shaft 4 is a hollow shaft, shared with motor 10, make compact structure so on the one hand, volume is little, and release transmission part, and increased the torsional rigidity of axle, improved transmission efficiency, eccentric shaft 4 right-hand members are equipped with and get rid of compression ring 11, the oil pump that has replaced former compressor, like this by the centrifugal force in the eccentric shaft high speed rotary, make left chamber form vacuum, right motor room pressure raises, cause a left side, the pressure reduction in right two chambeies, spill port 13 by body 7 bottoms, oil two oil-sucking holes in oil groove top 14 above oil groove base plate 1 are sucked lubricating oil, reach the purpose at lubricated relevant position, oil groove base plate 1 is installed in the bottom, be convenient to body 7 casting back sand removals, outlet valve 8 is arranged on the side (as the upper left side) on the upper side of body 7 along warp-wise, make a strength distribution of eccentric shaft 4 more reasonable, improved the resistance to flexure of eccentric shaft, in order to simplify mandatory cooling (as water-cooled, air-cooled) structure, strengthen radiating effect, help improving gas transmission efficient, on body 7 outsides, also be provided with multiple tracks annular radiating fin (sheet) 15, left end cap 2 is equipped with screw in the body two ends, right end cap 12, and sealed with sealing gasket, prevent that refrigeration working medium from leaking, changed the dead situation of former compression two ends weldering, constitute semi-closed structure, this greatly facilitates compressor and installs, maintenance, oil sucting valve 5 is contained in the top of left end cap 2, automatic oiling in can realization work, in actual applications, from looking oily mirror observable oil level, after putting in place with the valve rod half-twist of valve upper end, promptly stop oil-feed, revolution cylinder body 6 and piston 3 are contained on the same eccentric shaft 4, its working condition is by shown in Figure 2, when revolution cylinder body 6 and piston 3 are driven when revolving round the sun around the cylinder body center by eccentric shaft 4, on the other hand again around the eccentric shaft gyration center rotation that departs from the cylinder body center, in this process, relatively cylinder body slippage and cause the variation of cylinder pore volume, thus realize air-breathing, process of refrigerastion is finished in compression and exhaust.In the running, cylinder body and piston rotate synchronously, so claim two revolutions, it significantly is different from the drive manner of former compressor.

Also can ask seeing of Chu on mechanical mechanism principle shown in Figure 3, it is a kind of expansion of oscillating guidebar mechanism for a reality, and driving lever promptly is an eccentric shaft 4, and driven guide rod is revolution cylinder body 6, and slide block is piston 3, and eccentric shaft is with W ₁Rotating speed driven plunger 3, thus drive revolution cylinder body 6 with rotating speed W ₂O is worked as in rotation ₁Be in O ₁O ₂Extension cord top, piston place top dead center position just, otherwise, be in bottom dead center position.As long as satisfy: 1. O ₁O ₂〉=O ₁

O

₂2. slide block is made and is passed through O ₁The long garden cylindricality linking body structure of point as mechanism's conversion part, can realize that then guide rod (promptly turning round cylinder body 6) expands to garden turnover motion by swing, realizes two revolutions; It should be appreciated that especially, have into exhaust port on the body 7, be provided with to want rationally at the port phase angle, and different purposes have different phase angles, for example is used for when freezing, under safe health operating mode, the exhaust phase parallactic angle is 319 °, and there is not clearance volume in compressor, also not having inlet and outlet cuts down, this kind structure, according to theoretical calculation, its gas transmission efficient, to improve 15-20% than piston compressor, energy-saving effect is good.The power supply of motor 10 is introduced by terminal box 9.

The utility model also can be used as other compressors and uses.

Can find out clearly that by above-mentioned situation the utility model is simple in structure, novel unique, use easy to maintenance, all adopt homemade conventional material in the parts of its use, 80% all is to adopt standard piece and general part, and cost is low, be easy to produce, be easy to apply, use widely, market prospects are wide, have distinct economic and social effect, for further popularizing of chiller plant and air-conditioning equipment opened up new road.
