Low temperature hydraulic oil by hydraulic oil transfer pipeline 100 be to be back to second fluid chamber of fuel reserve tank 902 again to continue to supply
Equipment heating device 901.
The operation principle of wherein cooling line 200 is：
The high temperature and high pressure gas come out from compressor 202 becomes cryogenic high pressure gas liquid mixture after condenser 203, so
Gas-liquid separation is carried out by liquid storage device 204 afterwards and form cryogenic high pressure liquid, then by device for drying and filtering 205 remove
It is miscellaneous, low temperature and low pressure liquid then is formed by throttling set 207, low temperature and low pressure liquid is in heat-exchanger rig 102 by heat exchange shape
Into low-temp low-pressure gas liquid mixture, low-temp low-pressure gas liquid mixture carries out gas-liquid separation by gas-liquid separator 201 and forms low temperature
Low-pressure gas, then low temperature low pressure gas, which using compressor 202 compress, forms high temperature and high pressure gas, back and forth above-mentioned to follow
Ring, so as to which cooling line 200 cools down the hydraulic oil of the hydraulic oil transfer pipeline 100 by heat-exchanger rig 102.It is wherein cold
But the effect of the cooling line by-passing valve 208 in pipeline 200 is that pressure in cooling line 200 persistently increases and reaches certain value
When, cooling line by-passing valve 208 opens progress pressure release and plays a protective role to cooling line 200；Cooling line solenoid valve 206
Effect is when cooling line 200 is inoperative, and the liquid for placing 206 front of cooling line solenoid valve flow to compressor 202 backward
It is interior so that compressor 202 damages, and plays a protective role.
