Abstract
The utility model relates to the refrigeration technical field, in particular to a full enclosed motor-compressor. The motor-compressor comprises a shell, a motor, an eccentric shaft and an air cylinder and is characterized in that the bottom of the inner cavity of the shell is provided with a shock-absorbing supporting seat on which a stator of the motor is mounted; the stator is fixedly connected with an air cylinder rack on which the air cylinder is mounted; a suction silencer is arranged on the air cylinder; the upper part of the rotating shaft of the motor is the eccentric shaft, and a piston spherical connecting bar is movably matched with the eccentric shaft. The motor-compressor is characterized by compact structure, reasonable design, high work efficiency and low noise, which is applicable to the refrigerating cycle requirements of refrigeration agents R134a, 600, 404, 406, 410, 415, 501, 502, 507 and 22.
Description
Technical field
The utility model belongs to refrigeration technology field, particularly relates to a kind of fully-enclosed motor compressor.
Background technique
In chiller plants such as refrigerator, refrigerator, compressor is the main device in the chiller plant, its general reciprocating seal type motor compressor that adopts, mainly constitute by housing, stator, rotor, main shaft, connecting rod, piston and cylinder, by the to-and-fro motion of piston in cylinder, carry out the suction and the eliminating of gas refrigerant, to reach the effect of refrigeration.But the refrigeration agent that requires totally-enclosed compressor to use does not in recent years have destruction to environment, and requires efficient, low noise and miniaturization, thereby develops a kind of motor compressor of high-efficient low-noise, has become the problem that refrigeration technology field receives much concern.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, reasonable in design, high working efficiency, twin-tub single-stage fully-enclosed motor compressor that noise is low.
The purpose of this utility model is to adopt such technical solution to realize: it comprises housing, motor, eccentric shaft and cylinder, the bottom that it is characterized in that described housing inner chamber is provided with the shock-absorption support seat, the stator of described motor is installed on the shock-absorption support seat, on stator, be fixedly connected with cylinder frame, cylinder is installed on the cylinder frame, be provided with air suction silencer on cylinder, machine shaft top is eccentric shaft, and the piston spherical connecting bar of described cylinder cooperates with eccentric shaft is movable.
The utility model compared with prior art, because machine shaft cooperates with cylinder, the activity of piston spherical connecting bar, the structure of air-breathing noise reduction is set on cylinder, effectively utilized the space in the housing, improve the efficient of machine operation, and can be suitable for the refrigeration cycle requirement of R134a, 600,404,406,410,415,501,502,507,22 refrigeration agents.
