The utility model relates to a rolling rotor type compressor with silencer structure, comprising a closed shell (1), an electric motor (2) in the closed shell (1), a crankshaft connected with the electric motor (2), a rolling rotor (4) in the other end of the crankshaft (3), and an air cylinder (5) in which the rolling rotor (4) is contained. One side of the rolling rotor (4) is a main shaft bearing seat (8), and the other side of the rolling rotor (4) is a cylinder cover (10); a silencer (7) is configured between the cylinder cover (10) and an end cover (11); the cylinder cover (10) and the silencer (7) are oppositely combined (7) to form a first stage expanding chamber, and the silencer (7) is oppositely combined with the end cover (11) to form a second stage expanding chamber, thereby, the effective noise reducing frequency band of the compressor is enlarged, making the noise of the compressor is reduced.
Description
The utility model relates to a kind of full-sealed rolling rotator compressor, particularly a kind of full-sealed rolling rotator compressor that has noise elimination structure.
In existing full-sealed rolling rotator compressor, motor and its compression set that is driven all are contained in the housing of a sealing.The refrigeration working medium that comes from vaporizer enters compression set through suction tude, enters a silencing apparatus after compression, and such silencing apparatus normally has the anti-formula silencing apparatus of simple extension formula.Gas by silencing apparatus enters in the housing thereupon, flows into condenser more thus.The aerodynamic noise that mechanical noise that silencing apparatus produces when mainly being to reduce the outlet valve keying and gas produce when flowing through the outlet valve aperture, it is an important step that reduces the compressor total noise of centrifuge.Fig. 1 is the structural representation of above-mentioned full-sealed rolling rotator compressor.As shown in Figure 1, the motor (2) in the housing (1) rotates, and drives bent axle (3) and rotates, the feasible volume-variation that is made of rolling rotor (4) and cylinder (5), thereby pressurized gas.The expansion chamber (7a) that compressed gas enters silencing apparatus (7) by outlet valve (6), gas advances in the housing (1) through pore (5a) on the cylinder (5) and the row of the pore (8a) on the main bearing seat (8) from the outlet (7b) of silencing apparatus subsequently.Gas in the housing (1) is discharged compressor by outlet pipe (9).The shortcoming of this compressor is: the silencing apparatus on it is a simple extension chamber silencing apparatus, only the noise that reduces some frequency band is had effect on principle, and is then invalid to the noise of other frequency bands.In addition,, lack one section tubule and connect, also make the noise reduction of this simple extension chamber silencing apparatus decrease because the gas access end of silencing apparatus (7) is direct and outlet valve (6) joins.
The purpose of this utility model is by the improvement to the silencing apparatus on the existing rolling rotor type compressor, has strengthened the noise reduction of silencing apparatus, has particularly enlarged effective noise reduction frequency band, makes the noise of this compressor reduce greatly.
The utility model compared with prior art has following characteristics:
1 changes simple extension chamber silencing apparatus in the prior art into two expansion chamber silencing apparatus, makes that effective noise reduction frequency band is enlarged.Simultaneously the tubule that disposes certain-length in the outlet of the import of one-level expansion chamber and secondary expansion chamber connects, and makes the noise reduction of silencing apparatus to strengthen more.
2, the lubricating fitting with silencing apparatus and compressor structurally is integrated, and has saved material, has effectively utilized the space in the compressor housing.
Fig. 1 is the local figure in the longitudinal section of prior art.
Fig. 2 is the local figure in longitudinal section of the present utility model.
Fig. 3 is an end view of cylinder cap.
Fig. 4 is an end view of silencing apparatus.
Fig. 5 is another end view of silencing apparatus.
Fig. 6 is an end view of end cap.
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in detail.
With reference to Fig. 2, enter discharge chamber (10a) on the cylinder cap (10) through the gas after the compression set compression by air bleeding valve (6), the pulsation of gas is decreased, and gas enters one-level expansion chambers (15) along the semi-circular groove (7c) on the silencer (7) and carries out the first time and eliminate the noise then. Here semi-circular groove (7c) has served as the effect (seeing Fig. 4) of the tubule before the one-level expansion chambers. Gas flow is crossed through hole (7d) on the silencer (7) and is entered secondary expansion chambers (16) and carry out the second time and eliminate the noise subsequently. Then gas is by the outlet (7b) of silencer (7), and the through hole (10b), the through hole (5a) on the cylinder (5) and the through hole (8a) on the main bearing seat (8) that pass through on the cylinder cap (10) enter in the housing (1) again. Here through hole (7b), (10b), (5a) and (8a) have consisted of the tubule after the secondary expansion chambers.
The end cap (11) of silencer (7) also consists of the part of the pressure reduction lubricating arrangement of compressor. The oilhole of lubricating arrangement (12) be by the groove (7f) on the silencer (7) and Groove (11a) on the end cap (11) involutes. Through hole (7g) on the silencer (7) also consists of the part of oil circuit. Because the upper space (13) in the housing (1) is full of gases at high pressure, and lower space (14) is full of lubricating oil. In the gases at high pressure of upper space (13) and cylinder (5) under the differential pressure action of gas, lubricating oil upwards flows along oilhole (12) automatically, arrive again then the end of bent axle (3) by hole (7g), be assigned to again each need lubricated surface of compressor by the oil groove on the bent axle (3a), (3b) and (3c).
Fig. 3 is the view of the end face of cylinder cap (10) and silencer (7) applying. Figure can find out the shape of discharge chamber (10a) thus. One-level expansion chambers (15) among Fig. 2 is involutory and form by the recessed portion (7h) on the silencer (7) and the recess (10c) on the cylinder cap (10), and Fig. 3 also demonstrates the shape of recessed portion (10c). Through hole (10b) is the part of the passage behind the gas discharge silencer (7).
Fig. 4 is the view of the end face that fits of silencing apparatus (7) and cylinder cap (10).Semi-circular groove (7c) on the figure is communicated with exhaust cavity (10a) and one-level expansion chamber (15) get up, and has played the effect of the preceding configuration certain-length of one-level expansion chamber (15) tubule.The recessed portion (10c) of recessed portion (7h) and cylinder cap (10) is combined to form one-level expansion chamber (15).Through hole (7d) is communicated with the tow sides of silencing apparatus (7), is equivalent to the middle tubule section of two-stage expansion chamber.Through hole (7b) is the part of secondary expansion chamber (16) outlet pipe section.
Fig. 5 is the view of the end face that fits of silencing apparatus (7) and end cap (11).The recessed portion (11b) of recessed portion on the figure (7i) and end cap (11) is involutory and forms secondary expansion chamber (16).The effect of through hole (7b) and (7d) is identical with the explanation of Fig. 4.Groove (7f) constitutes the part of oilhole (12).
Fig. 6 is the view of the end face that fits of end cap (11) and silencing apparatus (7).The recessed portion (7i) that figure is recessed on part (11b) and silencing apparatus (7) is combined to form secondary expansion chamber (16), the involutory and upper oil hole (12) of formation lubricating fitting of the groove (7f) on groove (11a) and the silencing apparatus (7).
Adopt structure of the present utility model, not only can strengthen noise reduction, and can increase the topped frequency of silencing apparatus.Also reduce materials consumption in addition and effectively utilized the interior space of compressor housing.
