Technical field
The utility model relates to a kind of microminiature rolling rotor refrigeration compressor of totally-enclosed running.
Background technique
Existing compressor often has three kinds of defectives: 1. existing rolling rotor type cold compressor exhaust structure is offered outlet valve at down cylinder flange or casing top half flange respectively and directly gas is discharged; 2. the outlet valve offered at following cylinder flange of existing rolling rotor type cold compressor directly drains into baffler with the gas of high speed and high pressure, and the hole by baffler is discharged to the compressor oil oil storage pool.A large amount of lubricant oil is scratched with gas by the gas of high speed and high pressure and is discharged compressor, and the motor winding can only separate and have the seldom mist of oil of lubricant oil.A large amount of lubricant oil are discharged compressor with gas, cause the compressor lubrication oil mass to reduce in a large number, and the running gear of compressor can not get lubricating fully having increased friction power loss, has reduced operating reliability, and reduced the working life of compressor; 3. existing rolling rotor type cold compressor utilizes the casing top half flange to offer outlet valve gas is directly entered in the thin metal air separator that does not seal to discharge the pump housing then, though can separate lubricant oil through the motor winding.But this baffler is owing to too thin the sealing is difficult to the pulsations of gas is eliminated fully.Bring certain noise to compressor.
Summary of the invention
Technical problem to be solved in the utility model is to be compressor air-discharging pulsations in the solution prior art, and lubricant oil is discharged the defective of compressor, and then provides a kind of complete machine performance good, the microminiature rolling rotor refrigeration compressor of the reliable totally-enclosed running of turning round.
The utility model is achieved through the following technical solutions: a kind of microminiature rolling rotor refrigeration compressor of totally-enclosed running, comprise cylinder, upper flange, lower flange, rolling piston, exhaust partition, blade and motor, fixedly connected with cylinder by crankshaft main journal between described upper flange and lower flange, form a complete compressor pump, described motor and compressor pump tightly are enclosed within forms a compressor on the frame, the rotor of described motor stretches out one section with the bent axle of the bearing hole that is installed in upper flange and closely is connected, offer the outlet valve mounting groove on the described lower flange, arc-like rows air drain and circular sympathetic response groove, described exhaust partition sealing is installed on the lower flange plane and with the groove on the lower flange forms an exhaust cavity jointly, the lower end is lubricant oil storage pond, described outlet valve mounting groove has the exhaust port that communicates with the cylinder exhaust side on the plane, compressed gas is discharged from exhaust port in the cylinder, and gas enters circular sympathetic response groove through the arc-like rows air drain and eliminates the air pulsing noise.
As optimized technical scheme, described cylinder is provided with the exhaust passage.
As optimized technical scheme, described circular sympathetic response groove offers exhaust hole, and communicates with described exhaust passage, and gas enters the exhaust hole of cylinder and discharges through the upper flange through hole that communicates.
As optimized technical scheme, described motor internal is provided with a motor winding.
As optimized technical scheme, described exhaust partition is a circular piece, and middle place is provided with a big circular hole, and circular hole periphery place is provided with 4 small sircle holes.
The beneficial effects of the utility model are: two kinds of exhaust structures that the utility model will have compressor now merge, can effectively separate the shortcoming that lubricant oil is discharged with gas, and the shortcoming that the exhaust noise silencing chamber of forming can be eliminated the air pulsing noise is fully installed in the air vent on the lower flange and exhaust partition sealing, has promoted complete machine performance and operating reliability.
