Embodiment
Referring to accompanying drawing, the application is the detailed content that example further specifies invention with the hydraulic oil cooling system of simulator flight 5.
Analog machine 5 runnings require the oily temperature can constant a certain fixed temperature about 40 ℃, and the fluctuation of temperature is more little good more.The hydraulic working oil system of analog machine 5 is as shown in Figure 1, contains hydraulic oil container 1, oil hydraulic pump 2, hydraulic valve bank 3, oil hydraulic cylinder 4, to analog machine operation power is provided by oil hydraulic cylinder.
The present invention proposes a kind of frequency conversion cooling system to analog machine hydraulic oil; This cooling system can be exported a dynamic frequency-conversion cold; This cold size-controlled in the height of hydraulic oil temperature; Just the heat more than needed that can the balanced hydraulic system produces makes hydraulic oil oil temperature maintain 40 ℃ ± 1 ℃, guarantees that analog machine is stable, reliable operation.
As shown in Figures 2 and 3, the present invention mainly is made up of the electronic ratio adjusting valve of Three way type 17, sensor 10, controller 18, oil water heat exchange device 9, water pump valve group 13, swelling water tank 11, handpiece Water Chilling Units 14 etc.Wherein: the electronic ratio adjusting valve 17 of Three way type is used to distribute the ratio of the heat exchange water yield 21 and the backflow water yield 22; Sensor 10 is used to gather oil temperature signal; Controller 18 changes oil temperature signal into control signal, and the electronic ratio adjusting valve 17 of control Three way type is big or small in the aperture of heat exchange direction and backflow direction; Oil water heat exchange device 9 is places that cooling water and hydraulic oil carry out heat exchange; Water pump valve group 13 is power sources of cooling water system; Swelling water tank 11 is used for absorbing the change in volume of water body in process of expansion and contraction; Handpiece Water Chilling Units is used for tap water is processed into cooling water.
Above-mentioned hydraulic oil cooling system preferably is installed on handpiece Water Chilling Units 14 outdoor when implementing; Water pump valve group 13 is installed on handpiece Water Chilling Units 14 front ends, through water pump intrasystem tap water is squeezed into handpiece Water Chilling Units 14, handpiece Water Chilling Units output cooling water; Cooling water arrives Three way type dynamoelectric proportion valve 17 places through water-supply line; By controller 18 control shuntings, a part flows into oil water heat exchange device 9 as the heat exchange water yield 21, in heat exchanger, carries out heat exchange with hydraulic oil; Another part passes back into the chilled water system return pipe as the backflow water yield 22.Oil temperature sensor 10 is installed on the oil water heat exchange device 9 front end in-lines, gathers oily temperature information and sends controller 18 to, the assignment of traffic that controller 18 gets into oil water heat exchange device 9 according to 17 pairs of cooling waters of oil temperature information Control Three way type dynamoelectric proportion valve.Through debugging, on controller, setting oily temperature is 40 ℃, when the oily temperature of sensor 10 detections is higher than 40 ℃; Controller 18 control valve heat exchange direction apertures increase, and backflow direction aperture reduces, and increases the water output of cooling water with this; Promptly increase cold output, make oily temperature get back to 40 ℃ rapidly; Otherwise then heat exchange direction aperture reduces, and backflow direction aperture increases, and with this water output that reduces cooling water, it is constant to keep the oil temperature.Total Water remains unchanged in whole process, and reuses after the backflow water yield 22 entering systems, does not cause waste.
The present invention is through the output of frequency conversion cold, and is effectively that the oil temperature is constant in 40 ℃, and precision reaches ± and 1 ℃.Effectively raise heat exchange efficiency and reliability.Cooling water recycles, and saves resource.Utilize the electric control valve control water yield to realize the control of heat exchange quantity, can adapt to the fluctuation of heat exchange quantity under the different operating modes of analog machine, can remain the output cold and be slightly larger than or equal heat yield, save the energy to greatest extent.
