Description
Technical field
The utility model is related to technical field of refrigeration compressors, and in particular to a kind of cylinder body of refrigeration compressor.
Background technology
Refrigeration compressor is the core and heart of refrigeration system, and the ability and feature for compressing power traction determine refrigeration system
Ability and feature.In some sense, the design of refrigeration system is exactly to embody the ability of compressor with matching.Therefore, generation
Various countries of boundary refrigeration industry has put into substantial amounts of energy, new research direction and achievement in research in the research of refrigeration compressor invariably
Continuously emerge, the technology and performance level of compressor are maked rapid progress.
Compressor sucks the refrigerant gas of low-temp low-pressure from air intake duct, and it is pressed by motor rotation band piston
After contracting, to blast pipe discharge HTHP refrigerant gas, provide power for kind of refrigeration cycle, thus realize compression → condensation →
The kind of refrigeration cycle of expansion → evaporation (heat absorption).Compressor is general by housing, motor, cylinder body, piston, control device and cooling system
System composition.Cylinder body is as the main building block of compressor, and the performance to compressor plays the important and pivotal role, and works as piston
When being moved back and forth in cylinder body, larger frictional force can be produced so that easy to wear between cylinder body and piston, influence cylinder body
Service life；Therefore, typically between piston and cylinder can be provided with lubricating oil, but after piston movement its surface lubricating oil
It is whard to control, when lubricating oil crosses the phenomenon for axle center skew at most easily occur, when lubricating oil is less, frictional force occurs again too
Big situation, and then mechanical efficiency is influenceed, while fragile cylinder body.
Utility model content
The utility model in order to solve the above problems there is provided one kind it is simple in construction, low cost and can effectively control live
The cylinder body of the refrigeration compressor of lubricants capacity between plug and cylinder holes.
The utility model is adopted the following technical scheme that：
A kind of cylinder body of refrigeration compressor, including cylinder body body, the cylinder body body include pedestal and are arranged at pedestal top
The cylinder head of side is held, the cylinder head is provided with cylinder holes, and the inwall of the cylinder holes is provided with to be surround in the shape of a spiral along cylinder holes inwall
Groove, oil suction sponge block is provided with the groove, the bottom of groove is fixed in one end of the oil suction sponge block, and the other end prolongs
Stretch out outside groove.
As a kind of optimal technical scheme of the present utility model, the middle part of the pedestal is provided with crankshaft hole.
As a kind of optimal technical scheme of the present utility model, the groove and the cylinder holes inwall intersect what place was formed
Angle is all arc transition.
As a kind of optimal technical scheme of the present utility model, the depth of the groove for cylinder holes diameter length 1/15~
1/20。
As a kind of optimal technical scheme of the present utility model, the width of the oil suction sponge block is the 1/ of the width of groove
2~2/3.
As a kind of optimal technical scheme of the present utility model, the height that the oil suction sponge block extends outside groove is recessed
The 1/8~1/6 of groove depth.
The beneficial effects of the utility model are：
The utility model is simple in construction, and production cost is low, is provided with cylinder holes circular in the shape of a spiral along cylinder holes inwall
Groove, is provided with oil suction sponge block in groove, and the bottom of groove is fixed in one end of oil suction sponge block, and the other end extends groove
Outside, when piston moves reciprocatingly in cylinder holes, the oil suction sponge block end outside groove is extended due to being extruded by piston, sponge
Interior lubricating oil will flow out, the motion with the piston and then surface to piston is lubricated, so as to reduce piston movement
Frictional force；When the lubricating oil on cylinder holes wall or on piston is excessive, unnecessary lubricating oil can be flowed into groove again, due to recessed
The width of groove is more than the width of oil suction sponge block, therefore can reduce the speed of lubricating oil in oil suction sponge block oil suction groove, no
As for causing piston in motion because lubricating oil is excessive and causes axle center to offset.
Brief description of the drawings

Fig. 2 is the mplifying structure schematic diagram at A in Fig. 1；
Symbol description in figure：
Cylinder body body 1, pedestal 2, cylinder head 3, cylinder holes 4, groove 5, oil suction sponge block 6, crankshaft hole 7.
Embodiment
The utility model row is further described presently in connection with accompanying drawing.
As shown in figure 1, a kind of cylinder body of refrigeration compressor, including cylinder body body 1, the cylinder body body 1 includes the He of pedestal 2
It is arranged at the cylinder head 3 of the top side of pedestal 2, the cylinder head 3 and pedestal 2 are formed in one structure, the middle part of the pedestal 3
Provided with crankshaft hole 7, the middle part of the cylinder head 3 is provided with cylinder holes 4, and the inwall of the cylinder holes 4 is provided with along the inwall of cylinder holes 4 in the shape of a spiral
Circular groove 5, is provided with oil suction sponge block 6 in the groove 5, the side that one end of the oil suction sponge block 6 is bonded by glue
Formula is fixed on the bottom of groove 5, and the other end extends outside groove 5, and the inwall of the groove 5 and cylinder holes 4 intersects what place was formed
Angle is all arc transition.
The depth of the groove 5 is the 1/15 of the diameter length of cylinder holes 4, and the width of the oil suction sponge block 6 is the width of groove 5
The 1/2 of degree, during so that the lubricating oil on the inwall of proper cylinder holes 4 or on piston is excessive, unnecessary lubricating oil can flow into recessed
In groove 4, simultaneously because the width of groove 5 is more than the width of oil suction sponge block 6, absorb recessed therefore, it is possible to reduce oil suction sponge block 6
The speed of lubricating oil in groove 5, is unlikely to so that piston causes axle center to offset in motion because lubricating oil is excessive.
The height that the oil suction sponge block 6 extends outside groove 5 is the 1/8 of the depth of groove 5 so that oil suction sponge block 6 exists
It can be all squeezed into groove 5 when being extruded by piston, unnecessary part not had and is extruded between cylinder holes 4 and piston
And have influence on the motion of piston.
When the lubricants capacity in the oil suction sponge block 6 and groove 5 is very few, it can be stretched into by dropper in cylinder holes to inhaling
Oily sponge block 6 is refueled.
Finally it should be noted that：These embodiments are merely to illustrate the utility model without limiting model of the present utility model
Enclose.In addition, to those of ordinary skill in the art, can also make on the basis of the above description other various forms of
Change changes.There is no necessity and possibility to exhaust all the enbodiments.And thus amplify out it is obvious
Among change or variation are still in protection domain of the present utility model.
