By increasing the number of the high-pressure muffling cavities, the buffering of high-pressure air flow, and the noise and the vibration are reduced.
Description
Technical field
The utility model relates to a kind of frame of compressor, relates in particular to a kind of frame that can be used for the reciprocating piston type Totally-enclosed-type compressor in family expenses, commercialization and the middle-size and small-size refrigeration system.
Background technique
At present; Compressor has obtained using very widely in common life and engineering, and compressor is the heart of refrigeration system, the source of power; It is one of main path that realizes the national energy consumption of advocating; It back and forth moves through the running drive piston of motor, makes low-pressure gas carry out high pressure compressed, discharges the refrigerant gas of HTHP to exhaust cavity, outlet pipe; For refrigeration cycle provides the power of heat exchange, thereby realize the refrigeration cycle that the discharge → condensation of low-pressure gas suction → acting compression → high pressure-temperature gas is dispelled the heat → dammed → expand → evaporate and absorbs heat.Compressor generally comprises motor motivation, air suction silencer, cylinder head, valve group parts, piston, wrist pin, connecting rod, bent axle, frame, cover, casing, marshall springs, outlet pipe parts, control apparatus component such as (starter and protectors) composition.
Frame plays important effect in compressor, its bearing capacity and the stable working life that affects compressor to a great extent, the stability of compressor, reliability, performance index such as the efficiency of compressor, noise, vibration.Extraordinary stressed buffer function is played in the exhaust resistance of frame hyperbaric chamber (silencing cavity) during to compressor air-discharging, makes the stressed reduction of piston when high speed operation, can let the gas of HTHP obtain balanced exhaust simultaneously; Reducing the compressor complete machine impacts because of exhaust causes turbulence; Produce noise and vibration, yet original frame all adopts single-stage or two-stage silencing cavity, and cavity volume is less than normal; These factors have further strengthened the resistance of fluid, influence the ride quality of compressor.And consider the use field and the scope of design of compressor; Original compressor type is contoured design mostly, and the frame axis hole is short partially to the centre distance of frame cylinder face, and the design of connecting rod is restricted; Centre distance is short partially; Compressor axially loaded in the running is big, and it is enough big that the bearing capacity of bent axle and anti-twisting property will design equally, causes the secondary loss of compressor overall friction to increase.The hyperbaric chamber of former organic frame (silencing cavity) design all is to nestle up the piston hole side, makes on high-tension side temperature direct heat be delivered to piston hole, causes being heated inhomogeneously around the piston hole, and the friction the when refrigeration that has a strong impact on compressor is moved with piston is stressed.Former organic frame all adopts the supporting surface epirelief, and the plane is on same plane on every side, and connects through stiffening rib; Along with the continuous popularization of plane bearing and the utilization of groove, the space of bent axle sector diminishes, reduced thickness; The dynamic balancing of compressor does not reach desirable requirement, and it is big that vibration becomes, increase groove simultaneously after; The frame strength variation influences working life of compressor.Above situation has caused adverse factors to the complete machine performance (energy consumption, vibration, noise, low voltage startup, life-span etc.) of compressor.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the utility model provides a kind of frame of compressor of better performances.
The technological scheme that the utility model solves its technical problem is:
A kind of frame of compressor; Comprise the frame body; The frame body is provided with crankshaft hole, and with the cylinder-bore that the crankshaft hole vertical connection is provided with, described cylinder-bore one side is provided with a buffering and deposits air cavity; The opposite side of cylinder-bore is provided with one-level silencing cavity and secondary silencing cavity, and described one-level silencing cavity and secondary silencing cavity are communicated with through ladder hole.
As improvement, the cylinder face of cylinder is provided with buffering through hole and exhaust hole.
As improvement, the downside neck of frame body is provided with stiffening rib.
The utility model is provided with three hyperbaric chambers, and promptly buffering is deposited air cavity, one-level silencing cavity, secondary silencing cavity; When compressor operation, pressurized gas are discharged from piston hole, because overpressure; Form turbulent flow in the high pressure side and form bump, one-sided buffering is set deposits air cavity and can let the cylinder head internal pressure reduce, make balanced being discharged in the one-level silencing cavity of gas with cylinder head and hyperbaric chamber wall; The gas of high pressure high flow rate expands through the buffering of one-level silencing cavity and secondary silencing cavity, and flow velocity is reduced, and can significantly reduce the noise of compressor; Solve cavity volume problem less than normal, improved the buffering of high pressure draught, reduced turbulent impact noise and vibration that air-flow forms.Stiffening rib can increase mechanical strength, and the vibration of compressor is reduced, and prolongs the working life of compressor.
The beneficial effect of the utility model is: the utility model has increased the number of high pressure silencing cavity, can improve the buffering of high pressure draught, reduces noise and vibration.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 1,2,3, shown in 4; A kind of compressor frame is whole by the foundry goods of casting single forming, and the frame body that forms through fine finishing; The frame body is provided with crankshaft hole 1, four cylinder pin 9 that the cylinder-bore 12 vertical with crankshaft hole 1, stator are fixing and movement limited post 2,8.Cylinder-bore 12 1 sides are provided with a buffering and deposit air cavity 7, and the opposite side of cylinder-bore is provided with one-level silencing cavity 5 and secondary silencing cavity 3, and one-level silencing cavity 5 is communicated with through ladder hole 4 with secondary silencing cavity 3.Be designed with two connecting through holes on the cylinder face 6 of cylinder, one is buffering through hole 10, and another is an exhaust hole 11.When compressor operation, pressurized gas are discharged from piston hole, because overpressure; Form turbulent flow in the high pressure side and form bump with cylinder head and hyperbaric chamber wall; One-sided buffering is set deposits air cavity 7 and can let the cylinder head internal pressure reduce, make balanced being discharged in the one-level silencing cavity 5 of gas, the gas of high pressure high flow rate expands through the buffering of one-level silencing cavity 5 and secondary silencing cavity 3; Flow velocity is reduced, can significantly reduce the noise of compressor.In addition; Increase frame crankshaft hole 1 to cylinder face 6 distances, connecting rod centre distance suitably lengthens, and bent axle torsion angle and stressed arm of force length all reduce in the running to make compressor; The design bearing capacity and the anti-twisting property of bent axle can suitably reduce equally, and the secondary loss of compressor overall friction is further reduced.The hyperbaric chamber design of frame all has certain distance from the piston hole both sides, and on high-tension side temperature area of heat transfer and amount are obviously reduced, and being influenced by heat around the piston hole diminishes, and improved the refrigeration of compressor, and the friction when having reduced the piston operation is stressed.Frame body downside neck adopts stiffening rib 13 to connect, and stiffening rib adopts integrated type to connect on every side, can increase mechanical strength, and the vibration of compressor is reduced, and frame strength strengthens, and prolongs the working life of compressor.
