Description
Technical field
The utility model belongs to Technology of Compressor Refrigeration field more particularly to a kind of compact screw parallel connection compressor
Group.
Background technology
In existing cryogenic freezing cold storage refrigeration system, usually using single-stage compressor, but single-stage compressor is when dragging down temperature
Range of freezing is small, compression ratio is high and is carried out often in limiting condition, greatly reduces the compressor service life, and maintenance frequency increases,
And power consumption is big, causes unnecessary cost.
Screw cooling-water machine using screw compressor because obtain this name.Its refrigeration work consumption is than vortex cooling-water machine
Power is big, is mainly used in chemical plant, ink printing house, automobile factory or central air conditioner system or other large scale industry systems
Cold aspect.Existing screw compressor has that appearance and size is big, and volume bulky, occupied space is big more, and it is multiple to install connection
It is miscellaneous so that equipment investment expense, land development expense increase considerably.
Invention content
To solve the deficiencies in the prior art, the utility model provides a kind of compact-sized, easy for installation compact spiral shell
Rod-type parallel compressor unit.
To achieve the above object, the technical solution adopted in the utility model is：A kind of compact screw parallel connection compressor
Group, including rack, electric cabinet, and the screw compressor, oil eliminator, the liquid storage device that are connected with valve by pipeline；Institute
The rack stated is divided into first layer and the second layer, and rack first layer is neatly fixed at before and after the oil eliminator and liquid storage device
The right, the electric cabinet is fixed at the left front of rack first layer, and the rack second layer is equipped with behind electric cabinet
Frame, the screw compressor are fixed above the rack second layer；
The screw compressor at least contains two, the output end of the screw compressor and is laterally arranged
Collector is connected, and one end closing of the collector, the other end is connected with the input terminal of oil eliminator, and the collector is located at all
The output end of the homonymy of compressor, oil eliminator is connected with condenser input terminal.
Compared with prior art, the beneficial effects of the utility model are：1）The utility model structure design is compact, and space is set
Meter is reasonable, and good appearance occupies little space, and greatlys save equipment investment expense；2）The utility model uses screw compressor,
By the combination of multiple compressors, multi-level output power is obtained, can most preferably be adjusted according to practical cold, and low noise,
Anti- liquid hammer ability is strong, greatly improves the stability of unit operation.
Description of the drawings
Fig. 1 is the front view of the utility model, reference numeral：1- racks, 2- electric cabinets, 3- screw compressors, 4- oil
Separator, 5- liquid storage devices, 6- collectors.
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 compact screw parallel compressor unit, including rack 1, electric cabinet 2, and pass through pipeline
Screw compressor 3, oil eliminator 4, the liquid storage device 5 being connected with valve；The rack 1 is divided for first layer and the second layer,
The right of 1 first layer of rack is neatly fixed at before and after the oil eliminator 4 and liquid storage device 5, the electric cabinet 2 is fixed
It is arranged in the left front of 1 first layer of rack, the second layer frame of rack 1, the screw pressure is equipped with behind electric cabinet 2
Contracting machine 3 is fixed above the rack second layer；
The screw compressor 3 at least contains two, and the output end of the screw compressor 3 is arranged with lateral
Collector 6 be connected, one end of the collector 6 closing, the other end is connected with the input terminal of oil eliminator 4, the collector 6
In the homonymy of all screw compressors, the output end and condenser of oil eliminator 4（It is not drawn into figure）Input terminal is connected.
The operation principle of the utility model is：High pressure gas by screw compressor compression is converged through collector enters oil
The input terminal of separator isolates the lubricating oil in high pressure gas by oil eliminator, is condensed subsequently into condenser, low temperature cold
The output end of the condensed device of lime set enters liquid storage device, and the cryogenic liquid in liquid storage device enters evaporator, Low Temperature Liquid by expansion valve
Body exchanges heat through heat exchanger with extraneous, cryogenic liquid gasification heat absorption, to reach refrigeration effect, the high-temperature gas generated after gasification into
Enter screw compressor and carries out next round refrigeration cycle.
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.
