Hydraulic oil bypass line 300 flows, and hydraulic oil cools down without heat-exchanger rig 102；
Equipment heating device 901 runs a period of time and its internal hydraulic fluid temperature can be caused also to increase, and therefore equipment is sent out
The hydraulic fluid temperature of first fluid chamber that thermal 901 is expelled in fuel reserve tank 902 also raises, fuel reserve tank temperature sensor
908 or hydraulic oil transfer pipeline temperature sensor 103 to detect that the temperature of hydraulic oil reaches certain high temperature (Celsius more than 60
Degree), hydraulic oil bypass valve 301 cuts out, and hydraulic oil cools down through heat-exchanger rig 102, now the cooling on cooling line 200
Pipeline electromagnetic valve 206 starts, and cooling line 200 comes into operation, and cooling line 200 carries with hydraulic oil at heat-exchanger rig 102
High-temperature liquid force feed in pipeline 100 carries out heat exchange, cools down high-temperature liquid force feed so that cooled down by heat-exchanger rig 102
Low temperature hydraulic oil is that second the fluid chamber continuation supply being again back to fuel reserve tank 902 sets through hydraulic oil transfer pipeline 100
Preparation thermal 901.
Wherein the operation principle of cooling line 200 is:
After condenser 203, cryogenic high pressure gas liquid mixture, then warp is become from compressor 202 high temperature and high pressure gas out
Cross reservoir 204 and carry out gas-liquid separation formation cryogenic high pressure liquid, be then passed through device for drying and filtering 205 and carry out except water remove impurity, so
After form Low temperature low pressure liquid through throttling arrangement 207, Low temperature low pressure liquid in heat-exchanger rig 102 through heat exchange formed low temperature
Low-pressure gas-liquid mixture, low-temp low-pressure gas liquid mixture carries out gas-liquid separation through gas-liquid separator 201 and forms low-temp low-pressure gas
Body, then low temperature low pressure gas again through compressor 202 be compressed formed high temperature and high pressure gas, the most above-mentioned circulation, from
And the hydraulic oil of the hydraulic oil transfer pipeline 100 through heat-exchanger rig 102 is cooled down by cooling line 200.Wherein cooling tube
The effect of the cooling line bypass valve 208 in road 200 is that the pressure in cooling line 200 persistently raises when reaching certain value,
Cooling line bypass valve 208 is opened and is carried out pressure release and play a protective role cooling line 200；The work of cooling line electromagnetic valve 206
With being when cooling line 200 is inoperative, the liquid placing cooling line electromagnetic valve 206 front flow in compressor 202 backward,
Compressor 202 is damaged, plays a protective role.
It is arranged in parallel piston type relief valve 6 on the oil circuit at radiator 5 two ends, on oil circuit or on reserving liquid tank 2, temperature has been set
Degree sensor.
Described piston type relief valve 6 includes housing 601, piston 602 and two springs 603, the described horizontal cloth of housing 601
