Description
Technical field
The invention belongs to refrigeration compressor accessory technical field, and in particular to a kind of air suction silencer of refrigeration compressor.
Background technology
As is known in the industry, hermetically sealed refrigerating compressor unit would generally be provided with an air suction silencer inside it, refrigeration
Cylinder sucks refrigerant gas by air suction silencer during compressor operating, was both played and weakened inside compressor by air suction silencer
The heat effect of adstante febre refrigerant, and play to reduce and noise caused by pressure fluctuation and shake during refrigerant gas flow
It is dynamic, so as to help to reduce the running noises of compressor, while the work efficiency of compressor can be effectively improved, that is, improve system
The Energy Efficiency Ratio of cold compressor(COP).It follows that air suction silencer is the essential of current reciprocating hermetic refrigeration compressor
And be one of more important accessory.
There is foregoing good effect just because of air suction silencer, therefore paid close attention to all the time be subject to industry, and utilize
The technical information that various technological means use the anti-acoustic capability for improving air suction silencer is no lack of is seen in the literature, can be by this
It is not limited to open source literature confirmation exemplified below:Chinese patent Authorization Notice No. CN2663663Y recommends to have " muffler shell "
For refrigeration compressor, which solves the sealing problem between upper and lower casing, has for the COP values for improving foregoing
Contribute and can be with noise reduction;" muffler " that CN2705629Y is provided is equally to the sealing problem of the muffler in prior art
Improved, there is the effect to play the same tune on different musical instruments with foregoing CN2663663Y;" the sealed refrigeration compression that CN2733037Y is introduced
The characteristics of machine air suction silencer " is that hook-type linker is set in lower anechoic chamber and is separated into lower anechoic chamber by longitudinal baffle
1:The cavity volume of 3 two not co-contents, the patent is helpful for reducing air suction and noise band frequency, but overall noise reduction is still not
Sufficiently achieve it is intended that degree;The structure of " New Energy-saving Deadender Of Closed Refrigerant Motor-compressor " that CN2833127Y is disclosed
Due to similar to foregoing CN2733037Y, technique effect is also similar;CN2886124Y disclose " refrigeration compressor is straight with half
Connect air suction silencer " it is helpful for convenient installation, and probability of failure can be reduced in the transportational process with refrigeration plant;
" air suction sound eliminator for refrigeration compressor " that CN201165957Y is recommended solves the problems, such as to prevent foreign matter from entering compresser cylinder.
Also, invention patent mandate notification number CN101487461B(The shell cover of air suction silencer of refrigeration compressor and housing
Fit structure)、CN101545472B(The air suction silencer of refrigeration compressor)And CN101545473B(The air-breathing of refrigeration compressor
Muffler)This three patents propose that wherein CN101487461B solves the shell of air suction silencer by the preceding title of the applicant
The problems such as covering the uneven and burr between housing, makes both combinations reach ultimate attainment degree;CN101545472B is ingenious
Ground solves the problems, such as the shield of covering to strainer, the objective technique effect for embodying the record of Instructions Page 3 15-18 rows;
CN101545473B isolates lid by being added between housing and shell cover, and is covered in isolation and be designed with cofferdam, and strainer is consolidated
It is scheduled on cofferdam, so that objective embody such as avoids debris from being damaged through strainer by what Instructions Page 3 10-14 rows were concluded
And the technique effect such as compressor, protection compresser cylinder.
In the technology contents for being not limited to air suction silencer of refrigeration compressor exemplified above, it is every be related to be intended to reduce
The technical solution of noise can substantially be summarized as the following aspects:First, the quantity of increase anechoic chamber;Second, lengthen suction line
Length;Third, reduce the effective area of suction line;Fourth, the suction line such as international publication number using complicated shape
" it is used for the air-breathing of refrigeration compressor disclosed in the Chinese invention patent application publication number CN101171424A of W02006/116830
Muffler ";Fifth, by increase anechoic chamber with lengthening suction line and storage and taking(I.e. and storage is used in combination).But these technological means
While muffler anti-acoustic capability is strengthened, the inspiratory resistance of muffler is also increased, so as to reduce the fortune of compressor complete machine
Row performance.
And then as is known in the industry, to drop whether no-float between the shell cover and housing of air suction silencer of refrigeration compressor
The quality for effect of making an uproar can have an impact.The fit form of foregoing shell cover and housing can be summarized as following three species by prior art
Type:First, buckle type;It is second, plastic sealed;Third, welded type.Shell cover and housing coordinated with snap-wise and is difficult to reach both it
Between sealing requirements, have a great influence to noise reduction generation;Although shell cover and housing are coordinated and can embodied in a manner of plastic packaging
Good sealing performance, but original size of muffler is changed, and not only needs to increase raw and auxiliary material in addition, but also need volume
Outer increase one set of die;Although being coordinated shell cover and housing with welding manner equally has excellent sealing effect, and will not
Change original size of housing and shell cover, but the pressure born i.e. bearing capacity is relatively fragile, is used in refrigeration compressor
During easily there is the problem of commissure swelling cracking, in view of this, it is necessary to be further improved, for this reason, the applicant makees
Beneficial design repeatedly, forms technical solution described below finally, and in the case where taking secrecy provision at this
The test center of applicant is tested, and is as a result proved to be practicable.
