nullSee Fig. 1，A kind of industrial hydraulic oil refrigeration machine that the present invention relates to，It includes a hydraulic oil transfer pipeline 100，Between hydraulic oil oil-in to hydraulic oil oil-out, hydraulic oil transfer pipeline delivery pump 101 and heat-exchanger rig 102 it is disposed with on this hydraulic oil transfer pipeline 100，The coolant outlet of described heat-exchanger rig 102 is disposed with gas-liquid separator 201 to the cooling line 200 cooled down between import、Compressor 202、Condenser 203、Reservoir 204、Device for drying and filtering 205、Cooling line electromagnetic valve 206 and throttling arrangement 207，Wherein condenser 203 can be one，Condenser 203 can also be provided with multiple in parallel or in series，It is provided with a cooling line bypass valve 208 between the cooling line 200 between cooling line 200 and throttling arrangement 207 to heat-exchanger rig 102 between compressor 202 to condenser 203.
Hydraulic oil transfer pipeline sensor 103 it is provided with on described hydraulic oil transfer pipeline 100, it is arranged in parallel a hydraulic oil bypass line 300 on the hydraulic oil transfer pipeline 100 at described heat-exchanger rig 102 two ends, described hydraulic oil bypass line 300 has been provided with hydraulic oil bypass valve 301.Hydraulic oil transfer pipeline sensor 103 detects when temperature is less than setting value or pressure higher than setting value, hydraulic oil bypass valve 301 is opened, hydraulic oil directly flows from hydraulic oil bypass line 300, hydraulic oil transfer pipeline sensor 103 detects when temperature is higher than setting value or pressure less than setting value, hydraulic oil bypass valve 301 cuts out, and hydraulic oil does not flows from hydraulic oil bypass line 300.
nullEquipment thermal source 900 includes equipment heating device 901 and fuel reserve tank 902，One piece of dividing plate being vertically arranged it is provided with in described reserving liquid tank 902，Dividing plate is respectively two fluid chambers by reserving liquid tank 902，First fluid chamber is provided with oil-in and the oil drain out of fuel reserve tank 902 of fuel reserve tank 902，Second fluid chamber is provided with oil-out and the oil return opening of fuel reserve tank 902 of fuel reserve tank 902，It is provided with filter at the oil drain out of fuel reserve tank 902 and the oil-out of fuel reserve tank 902，It is connected between the oil-out of equipment heating device 901 and the oil-in of fuel reserve tank 902 and has fuel reserve tank in-line 903，The oil drain out of fuel reserve tank 902 draws hydraulic oil drain line 904，It is connected between the oil-in of equipment heating device 901 and the oil-out of fuel reserve tank 902 and has fuel reserve tank outlet line 905，It is provided with fuel reserve tank oil-way circulation pump 906 on fuel reserve tank in-line 903 or fuel reserve tank outlet line 905，The oil return opening of fuel reserve tank 902 draws hydraulic oil return line 907，It is provided with a fuel reserve tank temperature sensor 908 in first fluid chamber of fuel reserve tank 902.
The hydraulic oil oil-in of described hydraulic oil transfer pipeline 100 and hydraulic oil oil-out are respectively by hydraulic oil oil-in flexible pipe and the hydraulic oil drain line 904 of hydraulic oil oil-out hose connection equipment thermal source 900 and hydraulic oil return line 907.
A kind of industrial hydraulic oil refrigeration machine is for the cool-down method of equipment thermal source:
Step one, connection equipment thermal source 900 and industrial hydraulic oil refrigeration machine；
The hydraulic oil oil-in of the hydraulic oil transfer pipeline 100 of industrial hydraulic oil refrigeration machine and hydraulic oil oil-out are respectively by hydraulic oil oil-in flexible pipe and the hydraulic oil drain line 904 of hydraulic oil oil-out hose connection equipment thermal source 900 and hydraulic oil return line 907；
After step 2, equipment thermal source 900 bring into operation, the hydraulic oil of 902 second fluid chambers of fuel reserve tank is through fuel reserve tank outlet line 905 supply arrangement electro-heat equipment 901, hydraulic oil in equipment heating device 901 drains into first fluid chamber of fuel reserve tank 902 by fuel reserve tank in-line 903, and the hydraulic oil of first fluid chamber sequentially passes through hydraulic oil drain line 904, hydraulic oil oil-in flexible pipe, hydraulic oil transfer pipeline 100, hydraulic oil oil-out flexible pipe and hydraulic oil return line 907 and is back to second fluid chamber of fuel reserve tank 902；
Equipment thermal source 900 initial operating stage, hydraulic fluid temperature is low, and hydraulic oil directly flows from hydraulic oil bypass line 300 in the flowing of hydraulic oil transfer pipeline 100, and hydraulic oil cools down without heat-exchanger rig 102；
nullEquipment heating device 901 runs a period of time and its internal hydraulic fluid temperature can be caused also to increase，The hydraulic fluid temperature of first fluid chamber in therefore equipment heating device 901 is expelled to fuel reserve tank 902 also raises，Fuel reserve tank temperature sensor 908 or hydraulic oil transfer pipeline sensor 103 detect that the temperature of hydraulic oil reaches certain high temperature (more than 60 degrees Celsius)，Hydraulic oil bypass valve 301 cuts out，Hydraulic oil cools down through heat-exchanger rig 102，Now the cooling line electromagnetic valve 206 on cooling line 200 starts，Cooling line 200 comes into operation，Cooling line 200 carries out heat exchange with the high-temperature liquid force feed in hydraulic oil transfer pipeline 100 at heat-exchanger rig 102，High-temperature liquid force feed is cooled down，Making the low temperature hydraulic oil cooled down by heat-exchanger rig 102 is that second fluid chamber being again back to fuel reserve tank 902 continues supply arrangement electro-heat equipment 901 through hydraulic oil transfer pipeline 100.
Wherein the operation principle of cooling line 200 is:
After condenser 203, cryogenic high pressure gas liquid mixture is become from compressor 202 high temperature and high pressure gas out, it is then passed through reservoir 204 and carries out gas-liquid separation formation cryogenic high pressure liquid, it is then passed through device for drying and filtering 205 and carries out except water remove impurity, it is then passed through throttling arrangement 207 and forms Low temperature low pressure liquid, Low temperature low pressure liquid forms low-temp low-pressure gas liquid mixture through heat exchange in heat-exchanger rig 102, low-temp low-pressure gas liquid mixture carries out gas-liquid separation through gas-liquid separator 201 and forms low temperature low pressure gas, then low temperature low pressure gas is compressed forming high temperature and high pressure gas through compressor 202 again, the most above-mentioned circulation, thus the hydraulic oil of the hydraulic oil transfer pipeline 100 through heat-exchanger rig 102 is cooled down by cooling line 200.Wherein the effect of the cooling line bypass valve 208 in cooling line 200 is that the pressure in cooling line 200 persistently raises when reaching certain value, and cooling line bypass valve 208 is opened and carried out pressure release and play a protective role cooling line 200；The effect of cooling line electromagnetic valve 206 is when cooling line 200 is inoperative, and the liquid placing cooling line electromagnetic valve 206 front flow in compressor 202 backward so that compressor 202 damages, and plays a protective role.
