Abstract
The utility model relates to a high efficiency low noise compressor's piston, including piston only (1), piston only (1) waist is provided with annular oil groove (2), and the afterbody is provided with step face (4), be provided with exhaust hole (3) on the annular oil groove (2). The utility model discloses the institute is through setting up annular oil groove (2) at piston afterbody oily step face of design and middle part to design exhaust hole (3) reduces piston and cylinder contact length on the one hand on annular oil groove (2) face, can effectively reduce piston and cylinder area of contact, reduces the compressor noise, can reduce compressor noise 0.5 -1.5dB, the on the other hand reduce friction wasted work reduces compressor input power, and consequently the coefficient of performance (COP) who promotes compressor has wide market prospect more than 4 percent.
Description
Technical field
The utility model relates to refrigeration compressor Component field, particularly a kind of piston of efficient low noise refrigeration compressor.
Background technique
The piston of existing refrigeration compressor, major part piston has oil groove in piston pin hole position and piston waist, small part is processing oil groove not, because reciprocal compressor does straight line motion, directly contact with cylinder at cylinder moving back and forth, make piston friction power consumption large, noise is high, refrigeration compressor performance can not be improved, and noise cannot reduce.
Summary of the invention
The utility model mainly solves the technical problem of reciprocating type refrigeration compressor efficiency, noise, provides a kind of structure simple, effectively can reduce the wasted work that rubs, and improves refrigeration compressor performance coefficient, reduces the piston of compressor noise.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of piston of efficient low noise refrigeration compressor, comprise piston only, it is characterized in that: described piston only waist is provided with annular oil groove, and afterbody is provided with step surface, and described annular oil groove is provided with exhaust port.
The width of described annular oil groove is 3-8mm.
Described exhaust port diameter is 1.5-2.5mm.
Described step surface width is 1-3mm.
The utility model has following technique effect: by piston tail being designed step surface and middle part design annular oil groove, in the middle part of piston, annular oil groove is designed with exhaust port, effectively can reduce piston and cylinder contact length on the one hand, reduce compressor noise, compressor noise 0.5-1.5dB can be reduced; Reduce friction wasted work on the other hand, reduce refrigeration compressor input power, promote the coefficient of performance (COP) more than 4% of refrigeration compressor.
Accompanying drawing explanation
Fig. 1 is the structural representation of compressor piston in prior art;
Fig. 2 is the structural representation of the utility model compressor piston.
Embodiment
As shown in Figure 2, a kind of piston of efficient low noise refrigeration compressor, comprise piston only 1, described piston only 1 waist is provided with annular oil groove 2, afterbody is provided with step surface 4, and described annular oil groove 2 is provided with exhaust port 3, and the width of described annular oil groove 2 is 5mm, described exhaust port 3 diameter is 2mm, and described step surface 4 width is 2mm.This piston only 1 one aspect effectively can reduce piston and cylinder contact length, reduces compressor noise, can reduce compressor noise 1.0dB; Reduce friction wasted work on the other hand, reduce refrigeration compressor input power, promote the coefficient of performance (COP) 5% of refrigeration compressor.
The above; be only the utility model preferably embodiment; but the utility model protection domain is not limited thereto, such as, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection domain of the present utility model.
Claims (4)
1. the piston of an efficient low noise refrigeration compressor, comprise piston only (1), it is characterized in that: described piston only (1) waist is provided with annular oil groove (2), afterbody is provided with step surface (4), described annular oil groove (2) is provided with exhaust port (3).
2. piston according to claim 1, is characterized in that: the width of described annular oil groove (2) is 3-8mm.
