Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
As shown in Figures 2 to 4, the compressor pump structure of the embodiment of the present invention includes upper flange 1, lower flange 2, the cylinder 3 being placed between upper flange 1 and lower flange 2 and gas passage 4, gas passage 4 runs through upper flange 1, cylinder 3 and lower flange 2, internal channel 5 it is arranged at intervals with in gas passage 4, internal channel 5 arranges pore 51, pore 51 makes internal channel 5 connect with gas passage 4, and the two ends of internal channel 5 provide import 52 and the outlet 53 of gas respectively.By arranging internal channel 5 in gas passage 4, and pore 51 is set makes gas passage 4 connect with internal channel 5, the import 52 that air-flow is provided by internal channel enters, and entered the region between gas passage 4 and internal channel 5 by pore 51, the outlet 53 provided by internal channel 5 is discharged, and inside and outside passage forms resonant cavity and shows good acoustic attenuation performance, and the pressure loss produced is less, the noise of exhaust airstream can be effectively reduced, produce impact without on overall performance simultaneously.
In the example of the present invention, compressor pump structure also includes deafener 9 and bottom silencer 10, and upper deafener 9 is bolted with upper flange 1, and bottom silencer 10 and lower flange 2 are bolted.Forming upper noise reduction chamber between upper deafener 9 and upper flange 1, form lower noise reduction chamber between bottom silencer 10 and lower flange 2, gas passage 4 is arranged between noise reduction chamber and lower noise reduction chamber.The gas passage 4 of the example of the present invention is be opened in upper flange 1, cylinder 3 and the pore on lower flange 2 respectively to connect the steam vent formed.In other examples of the present invention, gas passage 4 can also for being arranged at trachea on upper flange 1, cylinder 3 and lower flange 2, visible, the present invention is to the version of gas passage 4 and is not limited as, and meets and may be applicable to the present invention for the structure connecting upper noise reduction chamber and lower noise reduction chamber supplied gas circulation.
In the example of the present invention, internal channel 5 is the perforated pipe being arranged in gas passage 4, and is connected with gas passage 4 by being arranged at the fixture at gas passage 4 two ends.In other examples of the present invention, internal channel 5 is one-body molded also by particular manufacturing craft and gas passage 4.
Exemplarily, described fixture includes the first fixture 6, first fixture 6 includes: be adapted for insertion into the insertion section 61 in gas passage 4, for stopping that the first fixture 6 inserts the limiting section 62 of gas passage 4, runs through the first fixing hole of insertion section 61 and limiting section 62, perforated pipe is passed by the first fixing hole, and fixing with the first fixture 6 is connected.
Described fixture includes the second fixture 7, and the second fixture 7 includes the second fixing hole, and perforated pipe is passed by the second fixing hole, and spins with the second fixture 7 screw thread.
Example more specifically, welds the first fixture 6 on perforated pipe, and perforated pipe is passed by the first fixture and forms gas outlet 53, and the other end that perforated pipe is relative with the end of welding the first fixture 6 adopts male-pipe, and the second fixture 7 adopts the nut matched.During installation, the perforated pipe being welded with the first fixture 6 inserts until the limiting section 62 of the first fixture 6 abuts with upper flange 1 from the top of gas passage 4, being screwed in nut by the end of perforated pipe, until nut abuts with lower flange 2, the end of the perforated pipe stretching into nut forms gas feed 52.
The example of the present invention, perforated pipe adopts a diameter less than straight tube more than whole gas passage 4 length of the aperture of gas passage 4 and length.Thus, it is indoor that lower silencing cavity is stretched in the gas feed 52 that internal channel 5 provides, and it is indoor that silencing cavity is stretched in outlet 53.Gas is entered in internal channel 5 (such as, perforated pipe) by import 52, enters the region between gas passage 4 and internal channel 5 by pore 51 and forms resonant cavity, reaches noise elimination purpose.
The pore 51 of the example of the present invention is multiple along axially and/or radially offering respectively of internal channel 5 (such as, perforated pipe), and multiple pores are uniformly arranged, and the aperture of multiple pore is consistent.In other examples of the present invention, multiple pores along the axially or radially non-homogeneous arrangement of internal channel 5, and/or, the aperture of multiple pores is inconsistent.
In the example of the present invention, refer to Fig. 5 and Fig. 6, blocking part 8 is set between internal channel 5 and gas passage 4, be separated for the region between inward passage 5 and gas passage 4.By described design, the region between internal channel 5 and gas passage 4 is effectively separated, two chambers can be formed, import air-flow thereby through pore 51 and form double resonator, play soundproof effect more preferably.
As Typical non-limiting example, on internal channel 5 (such as, perforated pipe), weld toroidal membrane, then internal channel 5 and dividing plate are installed in gas passage 4.In other examples of the present invention, internal channel 5 and dividing plate can also be socketed, or, dividing plate can also be fixed in gas passage 4 in advance, then refills and joins internal channel, or, gas passage 4, internal channel 5 and dividing plate are one-body molded.
Preferably, there is between described dividing plate and gas passage 4 gap, and the difference of the internal diameter of the external diameter of described dividing plate and gas passage 4 is not more than 0.2mm.By this design, on the one hand can so that internal channel 5 and dividing plate be installed in gas passage 4, on the other hand, gap should not excessive be to ensure that can effectively form two chambers, it is prevented that separates and lost efficacy.
It is highly preferred that described dividing plate has multiple, the plurality of dividing plate is set in distance.So, it is possible in gas passage 4, form multiple resonant cavities, further enhance soundproof effect.
The example of the present invention, the first fixture 6 and/or described dividing plate adopt steel matter.
Fig. 7 is the erasure effect figure of the compressor pump structure described in the embodiment of the present invention, as shown in Figure 7, this figure presents single chamber perforated pipe and two-chamber perforated pipe acoustic transmission loss at different frequencies respectively, as seen from the figure, the acoustic transmission loss of two-chamber perforated pipe is more than the acoustic transmission loss of single chamber perforated pipe, namely the erasure effect of two-chamber perforated pipe is than the good muffling effect of single chamber perforated pipe, but relatively conventional steam vent noise-reducing structure, whether single chamber perforated pipe or two-chamber perforated pipe is respectively provided with bigger sound deadening capacity and broader frequency of noise elimination.
Embodiments of the invention additionally provide a kind of compressor, including the compressor pump structure of any of the above-described embodiment, repeat no more herein.
Embodiments of the invention additionally provide a kind of air-conditioner, and it adopts compressor as above.
