Technical field
The present invention relates to a kind of totally-enclosed internal high pressure structure compresses machine, specifically a kind ofly reduce the structure that oil mass told by compressor.
Background technique
The overwhelming majority machinery component, motor and the refrigeration oil of usual internal high pressure structure compresses machine are deposited in high-pressure chamber, compressor pump assembly is positioned at above motor, refrigeration oil is positioned at below motor, because high-pressure chamber is communicated with outlet pipe, when compressor operation, rotor rotates and forces refrigerant to produce sinuous flow, is discharged, cause compressor to tell oil mass too high together with a large amount of refrigeration oil by outlet pipe.
The following shortcoming of the too high existence of oil mass told by compressor:
1, in compressor start process, the refrigeration oil discharged along with refrigerant returns compressor needs certain hour, if compressor is told, oil mass is too high probably causes that refrigeration oil in compressor is all discharged and refrigeration oil does not return compressor, cause the serious oil starvation of compressor, the wearing and tearing of light then compressor component, heavy then compressor damage;
If it is excessive that oil mass told by 2 compressors, then the oil mass returning compressor is also large, for adopting the compressor of direct air suction structure probably to cause pump assembly liquid hammer, and infringement compressor;
3, for refrigeration system, if to tell oil mass excessive for compressor, then the refrigeration oil be present in heat exchanger will be more, and now refrigeration oil is attached on tube wall, seriously can reduce heat exchanger efficiency, and then reduce the overall efficiency of refrigeration system.
Therefore, for internal high pressure structure compresses machine, oil mass told by reduction compressor is very necessary, the mode generally adopted at present is before outlet pipe, increase by a baffle means, refrigerant is avoided directly to discharge outlet pipe, thus filter out a part of refrigeration oil, what this kind of mode reduced compressor to a certain extent tells oil mass, but effect is not very good.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of structure that oil mass told by compressor that reduces, significantly can reduce the oil mass of telling of compressor, and can use with traditional scheme simultaneously, reduce compressor further and tell oil mass.The technological means that the present invention adopts is as follows:
A kind ofly reduce the structure that oil mass told by compressor, comprise the pump assembly with upper cover being arranged on housing upper end, the bearings parts being fixed on described pump assembly lower end and be arranged on rotor below described bearings parts, the rotation of energy driving crank and motor stator, it is characterized in that: the described bearings parts circumference side relative with outlet pipe is provided with air guide port, and described air guide port is connected with the relief opening of described pump assembly; Described motor stator is circumferentially with guiding gutter; Be provided with the guide plate matched with described air guide port between described bearings parts and described motor stator, described air guide port is connected with described guiding gutter by the passage that described guide plate and described housing are formed; Described motor stator lower end is provided with the guide ring of circumference, and the annular pass that described guide ring and described housing are formed is connected with described guiding gutter.
Preferably, the cross-section area of described air guide port is more than or equal to the cross-section area of the relief opening of described pump assembly.
Preferably, the guiding gutter that described motor stator circumference is arranged is formed after the silicon steel plate arranging more than 2 flow-guiding mouths by multiple circumference is stacked into stator core, and this guiding gutter cross-section area is more than or equal to the cross-section area of the air guide port on described bearings parts.
Preferably, multiple oil drainage hole is provided with bottom described guide ring.
Adopt technological scheme of the present invention namely between main bearing supporting part and motor stator, to arrange a guide plate, the passage that this guide plate and housing are formed communicates with the air guide port of the gas guide groove on motor stator and main bearing supporting part simultaneously.Arrange a guide ring below motor stator, this guide ring and compressor housing can form an annular pass, and this passage communicates with the gas guide groove of motor stator, and guide ring bottom has multiple oil drainage hole simultaneously.
The present invention is achieved in that the gas that compressor pump assembly is discharged, and via the air guide port of main bearing supporting part, along the gas guide groove of guide plate by motor stator, enters the annular pass below motor stator, finally discharges compressor by relief opening.
The present invention has following beneficial effect:
1, when high speed refrigerant passes through the annular pass below motor stator, under the influence of centrifugal force, the refrigeration oil that density is larger then can be attached on the sidewall of the annular pass that guide ring is formed, then the aperture below guide ring, enter the oil sump below compressor, thus incidental oil mass in the refrigerant greatly reduced, and then reduce compressor tell oil mass, and the higher effect of refrigerant flow rate is more obvious;
2, because this device is forced refrigerant by above motor, enter below motor stator comparatively abundant to motor stator cooling, significantly can reduce motor temperature, improve the reliability of motor on the one hand, the efficiency of motor can be improved on the other hand to a certain extent, and then improve the efficiency of compressor;
The following compartition of compressor motor internal stator is two-part by the annular pass 3, formed due to guide ring, refrigerant is made not flow through rotor balance position, the mist of oil taken up when thus rotor counterweight can not be rotated takes away discharge, reduces compressor further and tells oil mass.
