Specific embodiment
As shown in Figure 2,3, compressor proposed by the present invention, comprising: the components such as two cylinders 1, two roller 2, crankshaft 3,
A roller 2 is equipped in each cylinder 1, roller 2 is rolled along the inner headed face of cylinder 1, and crankshaft 3 passes through two cylinders 1, and crankshaft 3 is set
There are two off-centre operations 31 along the setting of its axially spaced-apart, one off-centre operation 31 of corresponding configuration in each roller 3.Two cylinders 1 it
Between separated by partition 4, partition 4 is equipped with the tonifying Qi hole 41 of two cylinders 1 of connection, is close to the position of cylinder on tonifying Qi hole 41
Gas supplementing opening 11.Two cylinders 1 are mounted in shell 5, and the blowdown pipe 7 outside shell 5 is stretched out by the connection of connecting tube 6 in tonifying Qi hole 41,
Tonifying Qi hole 41 and the sealing of 6 tight fit of connecting tube, tonifying Qi hole 41, connecting tube 6 and blowdown pipe 7 together constitute air supply passage.
The present invention uses duplex cylinder compressor, for the single cylinder compressor of same discharge capacity, the discharge capacity of duplex cylinder compressor by
Two cylinders 1 share generation jointly, effectively reduce the eccentricity of off-centre operation 31 in single cylinder 1, increase the wall thickness of roller 2, make
Gas supplementing opening 11 to open up region bigger.
As shown in Figure 4,5, two cylinders 1 are respectively the first cylinder and the second cylinder, and the internal diameter of the first cylinder is R1, first
Roller outer diameter in cylinder is r1, a height of h of the cylinder of the first cylinder1, the internal diameter of the second cylinder is R2, outside the roller in the second cylinder
Diameter is r2, a height of h of the cylinder of the first cylinder2, total displacement V=π × h1×(R12-r1²)+π×h2×(R22-r22), preferred real
It applies in example, the shape and discharge capacity of two cylinders 1 are all identical, and total displacement V is twice of single displacement volume.The following table 1 shows
A kind of relationship under heating condition between compressor displacement and performance works as compressor displacement under specified heating condition (- 12 DEG C)
When V >=16.5cc, compressor horsepower rising has clearly resulted in Energy Efficiency Ratio decline obviously, changes curve shown in Figure 6；Following table
2 show under second of heating condition under specified heating condition (- 20 DEG C), as compressor displacement V≤12.0cc, compressor
Power rise has clearly resulted in Energy Efficiency Ratio decline obviously, changes curve shown in Figure 7.Therefore, the discharge capacity of compressor exists
It is optimal in the range of 12.0cc≤V≤16.5.
Table 1:
Table 2:
The diameter of off-centre operation 31 is designed on the basis of compressor displacement determines, it is therefore intended that it is straight to reduce off-centre operation 31
Diameter, to increase the interior circular diameter of roller 2, so that the region for opening up gas supplementing opening 11 on partition 4 increases, to increase air compensation, increase
Big seal distance achievees the effect that improve compressor efficiency to reduce leakage.The following table 3 shows off-centre operation 31 and compressor performance
Between relationship, when 31 diameter of off-centre operation be greater than 23.5mm when, the region that can open up gas supplementing opening 11 is too small, the gas supplementing opening 11 opened up
Diameter becomes smaller therewith, causes compressor tonifying Qi effect bad, and heating capacity is not high under worst cold case, ultimately causes compressor efficiency
Than very low；When being biased to 31 diameters of circle and being less than 20mm, it is unstable that shafting occur in compressor starts, causes compressor horsepower high,
It is also very low to ultimately cause compressor efficiency, or even is unable to stable operation, changes curve shown in Figure 8.Therefore, by two
The diameter of off-centre operation 31 is limited in the range of 20mm to 23.5mm, has not only guaranteed the operation stability of the compressor, but also guarantee
Compressor has good tonifying Qi effect and efficiency is relatively high, and in a preferred embodiment, the shape of two off-centre operations 31 is identical.

As shown in Figures 2 to 4, one end of crankshaft 3 is cased with first flange 8, and the other end of crankshaft 3 is cased with second flange 9, two cylinders
1 is clamped between first flange 8 and second flange 9, on crankshaft 3 be located at first flange 8 in shaft section diameter be B, 10mm≤B≤
16.6mm, it is C, 10mm≤C≤16.6mm that the shaft section diameter in second flange 9 is located on crankshaft 3, can both guarantee that crankshaft 3 had
There is preferable structural strength, and the efficiency of compressor can be improved.Preferably, the eccentricity of two off-centre operations 31 is limited to
In the range of 3.4mm to 3.8mm, the efficiency of compressor also can effectively improve.Further, by the cylinder Gao Jun of two cylinders 1
It is limited in the range of 14mm to 16mm, also can effectively improve the efficiency of compressor.
Further, as shown in Figure 3,4, two off-centre operations 31 be respectively close to first flange 8 the first off-centre operation and
Close to the second off-centre operation of second flange 9, the first eccentric diameter of a circle is A1, eccentricity e1,≥e1, the second off-centre operation
Diameter be A2, eccentricity e2,≥e2, meeting this condition is to guarantee that roller 2 can be smoothly covered respectively
On one off-centre operation, the second off-centre operation.
