(4) description of drawings
Fig. 1 is the main structural representation of looking of the present invention;
Fig. 2 is the plan view of Fig. 1.
(5) embodiment
See Fig. 1, Fig. 2, the present invention includes fuel tank 10, fuel tank 10 is installed in the cabinet 1, it also comprises hydraulic oil temperature control instrument 5, heater 6 and cooling system, hydraulic oil temperature control instrument 5 and heater 6 are installed on fuel tank 10 cover plates bottom respectively, and hydraulic pressure temperature controlling instrument 5, heater 6 and cooling system electricly connect with the testing machine controller respectively.Cooling system comprises air cooling system and constituent; Air cooling system comprises fan 2, fan pipeline and fan electromotor 3; Fan 2 is installed on 1 of the cabinet; Fan electromotor 3 is installed on fuel tank 10 and covers; The import of fan pipeline links to each other with the auxiliary tank 8 of testing machine, and its oil outlet links to each other with fuel tank 10; Auxiliary tank 8 is connected with safety valve 4; Safety valve 4 is installed on fuel tank 10 cover plates; Constituent comprises external water tank, water pump 9 and water composite cooling pipe 7; Water composite cooling pipe 7 is installed in the fuel tank 10, and it is connected with water pump 9, and water pump 9 connects into external water tank.Among the figure, external water tank and fan pipeline do not mark.
Below in conjunction with accompanying drawing, working procedure of the present invention is described: connect power supply once, set temperature-control range, suppose that temperature-control range is 20 ℃～30 ℃, when the hydraulic fluid temperature in temperature controlling instrument 5 detects fuel tank 10 was lower than 20 ℃, temperature controlling instrument 5 electrical signal testing machine controllers were by 6 work of controller drives heater, when hydraulic fluid temperature in the fuel tank 10 reaches more than 20 ℃, controller control heater 6 quits work; Detecting when temperature controlling instrument 5 that hydraulic fluid temperature surpasses is that temperature controlling instrument 5 electrical signal testing machine controllers are worked by the controller drives cooling system more than 30 ℃; When adopting air cooling system, the safety valve 4 that fuel tank 10 covers is in open mode, and the hydraulic oil in the auxiliary tank 8 enters the fan pipeline; When adopting constituent, testing machine controller control of pump 9 starts, cooling water in the external water tank circulates by the water composite cooling pipe 7 that water pump 9 enters in the fuel tank 10, the heat of hydraulic oil in the fuel tank 10 is taken out of, reach refrigeration, when temperature controlling instrument 5 detects after hydraulic fluid temperature is lower than 30 ℃ in the fuel tank 10, electrical signal testing machine controller is closed by controller control constituent.The selection of cooling system is in testing machine system initialisation phase chosen in advance; The application of cooling system can be used air cooling system or constituent separately, also can use air cooling system and constituent simultaneously.
