It is existing apparatus to increase temperature sensor 1 and temp control regulating instrument 2, hydraulic station on pressure station, including：Filter 8, band switch
9th, oil level indicator 10, bleeder plug 11, detection door 12, main pump 13, hydraulic oil cooling filter 14, air cleaner 15, cooling
Blower fan 5；Temperature sensor 1 is stretched into fuel tank, and by setting temp control regulating instrument 2 to realize constant temperature, master control output is adjusted to
30 degrees Celsius, pair control output is adjusted to 50 degrees Celsius, when temperature sensor 1 measures temperature more than 50 degrees Celsius, temperature control
Adjusting apparatus 2 sends high level signal to the PLC3 controllers of hydraulic station, simultaneously turns on warning device 7, and continuing warning reminding makes
User, PLC3 control A.C. contactors 4 turn on cooling blower 5, when temperature sensor 1 measures temperature less than 30 degrees Celsius, temperature
Degree controls to adjust the PLC3 that instrument 2 transmits the signal to hydraulic station, and PLC3 control A.C. contactors 4 turn on heater 6 and give hydraulic pressure
Oil heating so that temperature is maintained between 30 to 50 degrees Celsius.
Temp control regulating instrument 2 in the device selects XMT-122 type temperature digital display adjusting apparatus, temperature controlling range 0-
150 DEG C, control accuracy：1℃.The upper limit, lower limit set continuously adjustabe, band switch 9 can show measurement temperature, upper limit temperature respectively
