Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
The present invention discloses a kind of temperature control cooling recirculation system, comprising: high-order liquid case 1, experimental stand, low level liquid case 4 and benefit
Liquid case 5.Experimental stand has rack liquid case 31, is provided with outlet tube road, discharge pipeline and liquid back pipe road in rack liquid case 31.Out
The starting point of liquid pipeline is lower than the starting point of discharge pipeline, and high-order liquid case 1 is connected to rack liquid case 31, provides it coolant liquid,
Coolant liquid flows to the water inlet of engine 0 to be detected from outlet tube road, and when the coolant liquid that high-order liquid case 1 supplies is excessive, it has more
Coolant liquid just flow to low level liquid case 4 from discharge pipeline, and low level liquid case 4 is connected to back high-order liquid case 1, to realize coolant liquid
Circulation.Preferred experimental stand has at least two groups.
Liquid level sensor can also be set in rack liquid case 31.Liquid level is judged by the liquid level sensor, with energy
Liquid level in timely learning rack liquid case 31, can be very few to avoid internal coolant.And when coolant liquid is excessive, then pass through
The discharge of discharge pipeline, can be set discharge valve, the opening and closing of the valve can be by the signal of liquid level sensor on liquid overflow pipe road
Control.Also, the setting that in such an embodiment, the starting point of discharge pipeline can be contour with the starting point on outlet tube road is in rack liquid
On case 31, such as in bottom surface.
Liquid back pipe road is connected to the water outlet and rack liquid case 31 of engine 0 to be detected, is formed with first on liquid back pipe road
Temperature sensor 32 and time liquid valve 33 could be by the coolant liquids after using only in the case where temperature meets requirement
It is recycled back to rack liquid case 31.It is to be understood that returning liquid valve 33 and the indirect temperature signal control obtained by the first temperature sensor 32
Open and-shut mode processed is being kept it turning on into experiment process, returning liquid valve 33, to guarantee the cyclic process of coolant liquid.First temperature passes
Sensor 32 is only used for the monitoring of the leaving water temperature with detection engine 0 during heat examination, is not involved in the water temperature regulation of system, water temperature
Regulation is managed as the second temperature sensor (being illustrated below) built in rack liquid case 31.But pass through first temperature sensing
The monitoring of device can also reach same effect, that is to say, that the first temperature sensor and second temperature sensor are in some implementations
In example, a use can be selected.
In addition to above-mentioned low level liquid case 4, fluid infusion case 5 is also connected to high-order liquid case 1, and the benefit of supplement coolant liquid can be also carried out to it
It fills.Make-up valve 37 is provided between high-order liquid case 1 and rack liquid case 31.
It is noted that the level height highest of high-order liquid case 1 when in use, at least above rack liquid case 31, low level liquid case 4
Height it is minimum, at least below rack liquid case 31.
Liquid feed valve 34 is provided on outlet tube road；On outlet tube road between liquid feed valve 34 and engine to be detected 0,
Form the first bypass, the first bypass to low level liquid case 4.First bypass can recycle the coolant liquid retained in pipeline.
Further, further include blowning installation 6, the water outlet of engine 0 to be detected is connected to, by high pressure gas, by liquid along first
Bypass is blown into low level liquid case 4.Remaining coolant liquid is blown in low level liquid case 4 using blowning installation 6, more effectively utilizes cooling
Liquid.Tapping valve 35 is provided in first bypass.It is opened when carrying out discharging of waste liquid collection, blowning installation 6 and engine to be detected 0
Water outlet between be provided with and blow liquid valve 36, the opening when carrying out blowing operation.
Second temperature sensor and heater 38 are provided in rack liquid case 31.Second temperature sensor monitors platform in real time
The temperature (hereinafter referred to as fluid temperature) of coolant liquid in frame liquid case 31,3 temperature control points are arranged in fluid temperature, respectively low
Warm spot, halt, high temperature dot, when second temperature sensor monitors fluid temperature lower than low temperature point, heater starting starts pair
Coolant liquid in step liquid case 31 is heated, and is heated to halt and is terminated, when second temperature sensor monitors liquid temperature
When degree is higher than high temperature dot, high-order liquid case 1 to its for low temperature coolant liquid with equilibrium temperature, it is extra cold if the amount of injection is excessive
But liquid is immediately discharged to low level liquid case by liquid overflow pipe.
When opening test, coolant liquid carries out cold between the water inlet of rack liquid case 31 and engine to be detected 0, water outlet
But it recycles.Hair after the test, blows liquid valve 36, the opening of tapping valve 35, and liquid feed valve 34 returns the closing of liquid valve 33, and compressed air passes through
It blows liquid valve 36 and is passed through the purging for carrying out starting machine residue in pipeline, the liquid of blowout drains into the first bypass, converges into low level liquid case
4.In general, in heat examination: returning liquid valve 33 and liquid feed valve 34 is opened, tapping valve 35 is closed with liquid valve 36 is blown；When blowing liquid: returning liquid valve
33 and liquid feed valve 34, tapping valve 35 and blow the unlatching of liquid valve 36.
Further include preferably valve positioner 7, above-mentioned multiple groups valve: returns liquid valve 33, liquid feed valve 34, tapping valve 35, blows
The control terminal of liquid valve 36 and make-up valve 37 can be all disposed on the valve positioner 7.
In said structure, also there are the structures such as pressure gauge, such as detect the pressure gauge of pressure after blowing liquid valve 36, and
Pressure gauge etc. on outlet tube road.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
