Description
Technical field
The utility model belongs to compressor cooling field more particularly to a kind of novel two stage compressor set.
Background technology
Traditional refrigeration system there is a problem in that：1, the appearance and size of Spiral Lobe Refrigeration Compressor is big, occupies larger
Space.2, the intermediate mixing drum of unit is typically mounted at the front of compressor so that the repair of compressor is complicated.3, intermediate mixing
Bucket is easy savings compared with many greases of sauce, to influence its normal work.4, valve is installed in the end of entire unit, it is defeated replaces liquid storage device
When the filter of outlet, the refrigerant of entire unit need to all be recycled, not only wasted time, and the loss of refrigerant is big.It is existing
In some cryogenic freezing cold storage refrigeration systems, usually using single-stage compressor, the model but single-stage compressor freezes when dragging down temperature
It is high and run often in limiting condition to enclose small, compression ratio, greatly reduces the compressor service life in this way, improves maintenance rate, and
And power consumption is big.And existing Two-stage Compression unit does not account for hot stage, and operational efficiency is low, and cooling rate is slow.
Invention content
To solve the shortcomings of the prior art, the utility model provides a kind of novel two stage compressor that efficiency is high
Group.
To achieve the above object, the technical solution adopted in the utility model is：A kind of novel two stage compressor set, including electricity
Control case, low pressure compressor, high pressure compressor, oil eliminator, wind cooling oil cooler, the output end connection of the low pressure compressor
The tail end of the collector being laterally arranged, the collector is fixed with a threeway, and an outlet of threeway connects high pressure compressed by pipeline
The input port of machine, another outlet of threeway connect the input terminal of oil eliminator, the output end of the high pressure compressor by pipeline
Connect the input terminal of oil eliminator, the input terminal of the output end connection wind cooling oil cooler of the oil eliminator；It is described automatically controlled
The controllable a whole set of unit of case.
Further, to be equipped with one on the pipeline that threeway and the high pressure compressor are connect with, oil eliminator automatic
Solenoid valve is controlled, the control cabinet is controllable to automatically control solenoid valve.
Further, pressure sensor is equipped on the pipeline of low pressure compressor output end.
Preferably, the low pressure compressor is two, using being connected in parallel.
Compared with prior art, the beneficial effects of the utility model are：The utility model cools down initial stage in quick freezing repository, tunnel
Only low-pressure machine is run, and can be with full-load run, and when pressure drops to certain value, signal is transmitted to control cabinet by pressure sensor,
Automatically control solenoid valve of the control cabinet on control high pressure compressor pipeline is opened, and is just started to start high pressure compressor, be carried out double
Grade compression, such cooling rate is fast, economical operation, and efficiency is high.
Description of the drawings
Fig. 1 is the front view of the utility model.
Specific implementation mode
Below in conjunction with attached drawing and preferred embodiment, to provided according to the utility model specific implementation mode, structure, feature and its
Effect, detailed description are as follows.
As shown in Figure 1, a kind of novel two stage compressor set, including electric cabinet 1, low pressure compressor 2, high pressure compressor 3（Figure
In do not indicate）, oil eliminator 4, wind cooling oil cooler 5, the output end of the low pressure compressor 2 is connected to the collection being laterally arranged
The tail end of pipe, the collector is fixed with a threeway, and an outlet of threeway connects the input port of high pressure compressor 3 by pipeline,
Another outlet of threeway connects the input terminal of oil eliminator 4, the output end connection oil separation of the high pressure compressor 3 by pipeline
The input terminal of device 4, the input terminal of the output end connection wind cooling oil cooler 5 of the oil eliminator 4；The electric cabinet 1 is controllable
The a whole set of unit of system.
Further, it is automatic that one is equipped on the pipeline that threeway is connect with the high pressure compressor 3, oil eliminator 4
Solenoid valve is controlled, the control cabinet 1 is controllable to automatically control solenoid valve.
Further, pressure sensor is equipped on the pipeline of 2 output end of low pressure compressor, at cooling initial stage（High temperature
Section）, the autocontrol valve in threeway and oil eliminator connecting pipe opens, threeway in high pressure compressor connecting pipe from
Dynamic control valve is closed, and only low pressure compressor is run at this time, and cutting can be with full-load run, when pressure drops to certain value, pressure
Signal is transmitted to control cabinet by sensor, and automatically control solenoid valve of the control cabinet on control high pressure compressor pipeline is opened, just opened
Begin to start high pressure compressor, carries out Two-stage Compression.Cooling rate is fast in this way, economical operation, more comprehensive than common single machine two-stage screw bolt machine
It is high by 8% or so to close efficiency.
Preferably, the low pressure compressor 2 is two, using being connected in parallel.
The embodiment of the utility model is described in detail above, but the content is only the preferred embodiment of the utility model,
It should not be construed as limiting the practical range of the utility model.It is all according to all the changes and improvements etc. made by the utility model application range,
It should all still belong within the patent covering scope of the utility model.
