Abstract
The invention relates to a bipolar semi-closed refrigeration compressor. The bipolar semi-closed refrigeration compressor comprises a machine body, a motor, an airflow pipeline valve plate and a bipolar inter-cooling device. A supporting rod is arranged on the periphery of the machine body. At least two crankcases are arranged on the machine body, and high and low pressure connectors are arranged on the crankcases. An oil level mirror is arranged on the machine body. Crankcase pressure connectors are arranged at the two ends of the oil level mirror. A suction cutoff valve and an exhaust cutoff valve are arranged at one end of each crankcase. An intermediate pressure valve is arranged in the middle of the machine body, a high pressure cover is arranged at the top end of the machine body, and an oil discharge outlet and an oil pressure high pressure connector are formed in the high pressure cover. An oil heater base and an oil filter are arranged on a base of the machine body. The bipolar semi-closed refrigeration compressor has the advantages that the load power consumption is low, the exhaust gas temperature is low, the volume efficiency is high, the operation conditions of the compressor under the working condition of the low evaporating temperature are greatly improved, and the bipolar semi-closed refrigeration compressor can work reliably and stably for a long time at the evaporating temperature of minus 50 DEG C, and is widely applicable to quick-freezing facilities and industrial, agricultural and commercial refrigeration systems.
Description
Technical field
The present invention relates to a kind of Compressor Technology field, refer more particularly to a kind of bipolar economical series of compressor of semi-enclosed refrigeration。
Background technology
At present, compressor, low-pressure gas is promoted to a kind of driven fluid machinery of gases at high pressure。It it is the heart of refrigeration system; it sucks the refrigerant gas of low-temp low-pressure from suction nozzle; after driving piston that it is compressed by motor rotation; the refrigerant gas of High Temperature High Pressure is discharged to exhaustor; power is provided for kind of refrigeration cycle; thus realizing the kind of refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption); existing most of Compressor Manufacturing factory possesses production trigger and thermal protector; but as required from market purchasing; additionally overall structure is not compact, fluctuation of service。
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of 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 above-mentioned technical problem, the invention provides a kind of bipolar semi-hermetic refrigerating compressor unit, it is by body, motor, airflow line valve plate and twin-stage intercooler unit composition, described body periphery is provided with support bar, described body is provided with at least two crankcases, described crankcase is provided with height, low-pressure connector, described body is provided with pasta mirror, described pasta mirror two ends are provided with crankcase crimp head, described crankcase one end is provided with suction line valve and discharge line valve, intermediate pressure valve it is provided with in the middle part of described body, described body top is provided with high gland, described high pressure lid is provided with fuel outlet and oil pressure high voltage interface, described body base is provided with oil heater seat and by filter。
Described twin-stage intercooler unit includes intermediate plate heat exchanger, isothermal liquid injection valve, electromagnetic valve and night vision goggles, and described motor is low form motor。
Compared with prior art, advantage of the present invention is:
After whole equipment is completed, 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 compressor operating condition under low evaporating temperature operating mode。Can even 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。
Accompanying drawing explanation
Fig. 1 is the structural representation of the bipolar semi-hermetic refrigerating compressor unit of the present invention。
Detailed description of the invention
As shown in Figure 1, a kind of bipolar semi-hermetic refrigerating compressor unit, it is by body 1, motor 2, airflow line valve plate and twin-stage intercooler unit composition, described body 1 periphery is provided with support bar 3, described body 1 is provided with two crankcases 4, described crankcase 4 is provided with height, low-pressure connector 5, described body 1 is provided with pasta mirror 6, described pasta mirror 6 two ends are provided with crankcase crimp head 7, described crankcase 4 one end is provided with suction line valve 8 and discharge line valve 9, it is provided with intermediate pressure valve 10 in the middle part of described body 1, described body 1 top is provided with high gland 11, described high gland 11 is provided with fuel outlet 12 and oil pressure high voltage interface 13, described body 1 base is provided with oil heater seat 14 and by filter 15。
Described twin-stage intercooler unit includes intermediate plate heat exchanger, isothermal liquid injection valve, electromagnetic valve and night vision goggles。Described motor 2 is low form motor。
Wherein require maximum allowble pressure Mpa suction side, 2.1, exhaust side 3.0, maximum pressure differential Mpa is low-pressure stage 0.8, hiigh pressure stage is 1.6, and maximal inspiratory pressure power saturation temperature is low-pressure stage 25 DEG C, and most high exhaust temperature is low-pressure stage 115 DEG C, hiigh pressure stage 135 DEG C, using evaporating temperature scope DEG C is-25 DEG C-50 DEG C。
