Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to embodiment set forth herein.On the contrary, thesing embodiments are provided so that the present invention will
Fully and completely, and by the design of example embodiment comprehensively it is communicated to those skilled in the art.It is identical attached in figure
Icon note indicates same or similar structure, thus will omit repetition thereof.
Fig. 1 is the cross-sectional view of single cylinder compressor of the invention.Fig. 2 is the partial enlarged view in Fig. 1.As illustrated in fig. 1 and 2,
Single cylinder compressor of the invention, comprising: shell 1, piston 2, crankshaft 3, cylinder 4, motor 5 and receiver 6.Motor 5 and cylinder 4
It is placed in the shell 1.Piston 2 is rotatablely arranged in the cylinder 4.Crankshaft 3 has an eccentric part, the crankshaft 3
The rotary force of motor 5 is passed into the piston 2, the eccentric part drives the piston 2 to rotate in the cylinder 4, with pressure
Contraction cryogen.Receiver 6 stores refrigerant, and the receiver 6 is connected to the cylinder 4 by a pipeline.The cylinder 4
The internal diameter D of height H, cylinder bore diameter F and shell 1, three meet: H > 0.490F and H≤0.295D.It include first in the present invention
Bearing assembly 7 and second bearing component 8 limit compression space with the cylinder jointly and support the crankshaft, and the cylinder is high
Degree H is the spacing between the first bearing component 7 and second bearing component 8.It is disc space, institute inside the cylinder 4
State the diameter that cylinder bore diameter F is the disc space.It is cylindrical space inside the shell 1, the housing inner diameter D is institute
State the diameter of cylindrical space.
Single cylinder compressor in the present embodiment is a kind of rotary single cylinder compressor, including seal casinghousing 1, piston 2, crankshaft
3, the components such as cylinder 4, motor 5, crankshaft 3 rotate under the driving of motor 5, and crankshaft eccentric portion band piston 2 rotates, in cylinder 4
It is formed air chamber V (low-pressure gas is compressed into high pressure gas, and high-low pressure chamber is isolated by blade).The discharge capacity of rotary single cylinder compressor
V calculation formula are as follows: V=π × H × E × (F-E), wherein H is single cylinder compressor cylinder height, and E is single cylinder compressor crankshaft eccentric
Amount, F are single cylinder compressor cylinder bore diameter, then it is inclined to depend on cylinder height, cylinder bore diameter, crankshaft for the size of single cylinder compressor discharge capacity
Heart amount.Single cylinder compressor discharge capacity is proportional to cylinder height, cylinder bore diameter, crankshaft eccentric amount, and increasing cylinder height will cause laterally
Leakage loss increases, and increasing cylinder bore diameter will receive the influence of single cylinder compressor housing inner diameter D, and increasing eccentricity will lead to bias
Portion increases mechanical friction loss, and therefore, the object of the invention develops that a kind of to meet the small shell diameter of H/F > 0.490 and H/D≤0.295 big
Discharge capacity rotary extrusion type spinning single cylinder compressor.Such as: the cylinder bore diameter of the single cylinder compressor in the present embodiment is that 53mm housing inner diameter is
123mm, then the range of single cylinder compressor cylinder height H be: 25.97mm < H≤36.285mm.
Fig. 3 is the function curve schematic diagram of the cylinder height H and single cylinder compressor efficiency P of single cylinder compressor of the invention.
As shown in figure 3, in another embodiment, cylinder height H has similar parabolic with single cylinder compressor efficiency P in compressor of the invention
The track of line, segmentation is illustrated below:
When cylinder height H rises to 25.97mm from 16mm, the growth of cylinder height H has directly facilitated single cylinder compressor
The growth of efficiency P, the growth of cylinder height H are approximately proportional to the growth of single cylinder compressor efficiency P, within this range, increase gas
Cylinder height H can effectively improve single cylinder compressor efficiency P.
When cylinder height H rises to 36.285mm from 25.97mm, the growth of cylinder height H is for single cylinder compressor energy
What imitate P to act on without, within this range, single cylinder compressor efficiency P can not almost be improved by increasing cylinder height H.
When cylinder height H rises to 46mm from 36.285mm, the growth of cylinder height H is not only without increasing single cylinder compression
Function imitates P, instead because the reasons such as lateral leakage loss, reduce single cylinder compressor efficiency P.
Although single cylinder compressor discharge capacity is proportional to cylinder height, cylinder bore diameter, crankshaft eccentric amount, compressor displacement is mentioned
It rises, can be realized by increasing cylinder bore diameter, increasing crankshaft eccentric amount or increasing cylinder height, but when shell diameter is certain
When, the above two are limited discharge capacity promotion, and only increase cylinder height can be such that discharge capacity maximizes.But it is high to increase cylinder
Degree will cause clearance volume increase, influence performance, while the increase in crankshaft eccentric portion, influence the reliability of single cylinder compressor, increases
Aerating cylinder height can make pump housing whole height increase, influence the oil yield of single cylinder compressor, while being unfavorable for the small of compressor
Type.
To sum up, in single cylinder compressor of the invention cylinder height H, cylinder bore diameter F and compressor housing internal diameter D, three
Meet: H > 0.490F and H≤0.295D enable to single cylinder compressor to take into account and consider that excellent performance, good reliability, oil yield are low.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
