Abstract
The utility model discloses a kind of pulsation silencer for screw refrigerator, the described pulsation silencer for screw refrigerator comprises the noise reduction cylindrical shell of the cylindrical shape of a hollow, the two ends of described noise reduction cylindrical shell are respectively equipped with the Joining clasp of an annular, the outer wall of described noise reduction cylindrical shell is provided with the location snap ring of an annular, and the inwall circumference of described noise reduction cylindrical shell is provided with the Noise reduction tile strip array be made up of the Noise reduction tile bar of " C " font.The advantage of the pulsation silencer for screw refrigerator of the present utility model is: during use, user utilizes Joining clasp to be connected with the relief opening of the compressor of refrigeration agent, when the pulsation exhaust of helical-lobe compressor is through noise reduction cylindrical shell, due to Noise reduction tile bar guide functions, greatly reduce the fluctuation pressure of the exhaust of compressor, thus greatly reduce the exhaust noise of helical-lobe compressor, effectively improve the performance of screw refrigerator.
Description
Technical field
The utility model relates to a kind of chiller plant, or rather, is a kind of pulsation silencer for screw refrigerator.
Background technique
Screw refrigerator is a kind of common industrial refrigeration equipment, extrudes refrigeration agent by cooperatively interacting of negative and positive rotor, and therefore, the pulsation exhaust of this refrigerator easily brings great noise, affects the performance of refrigerator.
Summary of the invention
The utility model mainly solves the technical problem existing for prior art, thus provides a kind of pulsation silencer for screw refrigerator.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of pulsation silencer for screw refrigerator, the described pulsation silencer for screw refrigerator comprises the noise reduction cylindrical shell of the cylindrical shape of a hollow, the two ends of described noise reduction cylindrical shell are respectively equipped with the Joining clasp of an annular, the outer wall of described noise reduction cylindrical shell is provided with the location snap ring of an annular, and the inwall circumference of described noise reduction cylindrical shell is provided with the Noise reduction tile strip array be made up of the Noise reduction tile bar of " C " font.
As the utility model preferred embodiment, the inwall of described Noise reduction tile bar and described noise reduction cylindrical shell is welded to connect.
As the utility model preferred embodiment, described Noise reduction tile bar is that stainless steel thin slice is made.
The advantage of the pulsation silencer for screw refrigerator of the present utility model is: during use, user utilizes Joining clasp to be connected with the relief opening of the compressor of refrigeration agent, when the pulsation exhaust of helical-lobe compressor is through noise reduction cylindrical shell, due to Noise reduction tile bar guide functions, greatly reduce the fluctuation pressure of the exhaust of compressor, thus greatly reduce the exhaust noise of helical-lobe compressor, effectively improve the performance of screw refrigerator.This pulsation silencer 1 structure being used for screw refrigerator is simple, and successful is practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figures 1 to 5, this pulsation silencer 1 being used for screw refrigerator comprises the noise reduction cylindrical shell 2 of the cylindrical shape of a hollow, the two ends of this noise reduction cylindrical shell 2 are respectively equipped with the Joining clasp 3 of an annular, the outer wall of this noise reduction cylindrical shell 2 is provided with the location snap ring 21 of an annular, and the inwall circumference of this noise reduction cylindrical shell 2 is provided with the Noise reduction tile strip array be made up of the Noise reduction tile bar 4 of " C " font.
This Noise reduction tile bar 4 is welded to connect with the inwall of this noise reduction cylindrical shell 2.
This Noise reduction tile bar 4 is made for stainless steel thin slice.
During use, user utilizes Joining clasp 3 to be connected with the relief opening of the compressor of refrigeration agent, when the pulsation exhaust of helical-lobe compressor is through noise reduction cylindrical shell 2, due to Noise reduction tile bar 4 guide functions, greatly reduce the fluctuation pressure of the exhaust of compressor, thus greatly reduce the exhaust noise of helical-lobe compressor, effectively improve the performance of screw refrigerator.
This pulsation silencer 1 structure being used for screw refrigerator is simple, and successful is practical.
Be not limited to this, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
