Abstract
The cooling oil device of more refrigeration compressor set parallel combinations, is related to a kind of refrigeration equipment.Including condenser, evaporator, compressor, pass through closed circulation piping connection between the evaporator, compressor, condenser, liquid storage device, filter are equipped on pipeline between condenser and evaporator successively, condensation fan is correspondingly arranged on outside condenser, is provided with by cooling oilway in evaporator；Compressor is arranged at least two, and respectively by piping connection to same gas and oil equilibration bucket, the import of gas and oil equilibration bucket is connected on the closed circulation pipeline being connect with evaporator outlet each compressor.Present apparatus stability is high, operating cost is low, reduces the waste of the number electric energy of power mismatch and high-power compressor start and stop；It is easy to maintenance, at low cost.
Description
Technical field
The utility model is related to a kind of refrigeration equipments, are mainly used for plates of automobile former, forging machinery equipment, numerical control
The hydraulic system of shearing equipment, the cooling temperature control of lubricating system.
Background technology
Existing tradition Cool oil machine mostly uses greatly single compressor and carries out refrigeration cool-down to fluid, when hydraulic system or lube system
When calorific value of uniting changes, single compressor refrigerating capacity cannot match, corresponding calorific value, and single compressor refrigerating capacity is more than fever
When amount, high frequent can be caused to start, cause the reduction of compressor service life and frequent starting causes waste electric energy；Separate unit compresses
When mechanism cold is less than calorific value, temperature control requirement is not achieved.
Further more, separate unit high-power compressor, once being damaged, replacement cost is extremely expensive.
Utility model content
In order to overcome the shortcomings of the prior art, the utility model provides a kind of more refrigeration compressor set parallel combinations
Cooling oil device.
The utility model includes condenser, evaporator, compressor, by closing between the evaporator, compressor, condenser
Circulation line connection is closed, liquid storage device, filter, condenser are equipped with successively on the pipeline between the condenser and the evaporator
It is correspondingly arranged on condensation fan outside, is provided with by cooling oilway in the evaporator；The compressor is arranged at least two, each pressure
Respectively by piping connection to same gas and oil equilibration bucket, the import of gas and oil equilibration bucket is connected to be connect contracting machine with evaporator outlet
On closed circulation pipeline.
The utility model substitutes high-power compressor using two or multiple compressors parallel connection, is meeting the big liquid of thermal change
Under the premise of pressure system temperature control requires, additionally it is possible to according to heating capacity, start the compressor of corresponding number of units, system is more stablized
Property, operating cost it is low, reduce power mismatch and high-power compressor start and stop number electric energy waste.When compressor damages
Bad only to need replacing the low power compressor of damage, high-power compressor is replaced in comparison, and maintenance cost is low.Gas and oil equilibration is set
Bucket so that each system compressors return-air resistance is impartial, and then ensures that each system oil gas reflux is impartial, ensures each compression captain
Phase reliability service.
The utility model is respectively mounted check valve in the exit of every compressor；Ensure that each compressor is individually being transported
It goes or does not influence other compressors when running simultaneously.
The compressor horsepower of the utility model every is the 1/N of the required high-power compressor of total heating capacity, and N is institute
State the number of units of compressor.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, the cooling oil device of this more refrigeration compressor set parallel combinations, including condenser 1, evaporator
2, compressor 3 are connected between evaporator 2, compressor 3, condenser 1 by closed circulation pipeline 4, condenser 1 and evaporator 2 it
Between pipeline on be equipped with liquid storage device 5, filter 6 successively, be correspondingly arranged on condensation fan 7 outside condenser 4, setting in evaporator 2
Have by cooling oilway 8；Compressor 3 is arranged at least two, each compressor 3 respectively by piping connection to same gas and oil equilibration bucket 9,
The import of gas and oil equilibration bucket 9 is connected on the closed circulation pipeline connected with the outlet of evaporator 2, per the exit of compressor 3
It is respectively mounted check valve 10.
It is the 1/N of the required high-power compressor of total heating capacity per 3 power of compressor, N is the platform of the compressor
Number, N >=2 pass through multiple compressors parallel connection so that the arbitrary control of device compressor power, while super high power may be implemented
Refrigerating capacity.
