Description

Bipolar semi-hermetic refrigerating compressor unit
Technical field
The utility model relates to a kind of Compressor Technology field, refers more particularly to the economical series of compressor of a kind of bipolar semi-enclosed refrigeration.
Background technique
At present, compressor, is promoted to a kind of driven fluid machinery of pressurized gas by low-pressure gas.It is the heart of refrigeration system; it sucks the refrigerant gas of low-temp low-pressure from sucking pipe; after driving piston to compress it by motor rotation; the refrigerant gas of High Temperature High Pressure is discharged to outlet pipe; for refrigeration cycle provides power; thus realize the refrigeration cycle of compression → condensation (heat release) → expand → evaporate (heat absorption); existing most of Compressor Manufacturing factory possesses production starter and heat protector; but as required from market purchasing; overall structure is not compact in addition, fluctuation of service.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind ofly has the semi-hermetic refrigerating compressor unit that load wasted work is little, delivery temperature is low, volumetric efficiency is high.
In order to solve the problems of the technologies described above, the utility model provides bipolar semi-hermetic refrigerating compressor unit, it is made up of body and motor, described body upper end is provided with crankcase, described crankcase is provided with height, low-pressure connector, described height, low-pressure connector one end is provided with discharge line valve, described body side is provided with bottom, oil pressure high pressure valve is arranged with outside described bottom, described body one end is provided with subcooler, described crankcase is connected with subcooler by pipeline, described subcooler upper end is provided with the refrigerant inlet of subcooler, described subcooler lower end look also has the refrigerant outlet of liquid supercooler, described body upper end is also provided with oil pocket, described oil pocket is provided with suction line valve, body lower end is provided with base, described base is provided with oil strainer, described oily subcooler two ends are provided with fuel outlet and oil return plug screw.
Described body side is provided with pasta mirror, and described motor is low form motor, and described pasta mirror two ends are provided with crimp head in crankcase.
Compared with prior art, the utility model advantage is:
After whole device assembles completes, adopt Two-stage Compression structure, and be aided with interstage cooler structure, its power of motor 7.5HP ~ 40HP, there is the distinguishing features such as load wasted work is little, delivery temperature is low, volumetric efficiency is high, substantially improve the operating condition of compressor under low evaporating temperature operating mode.Can smooth running stably in a long term under the evaporating temperature of-50 degree.This machine is widely used in quick freezing unit, work, agriculture, commercial refrigeration system.
