Description
Technical field
The present invention relates to examine and determine the special-purpose calibration equipment of temperature element, particularly a kind of automatic constant temperature fluid bath of examining and determine temperature element.
Background technology
The qualification calibrating of temperature element is that each enterprise, metrological supervision department guarantee the effective means that enterprise security is produced all the time.Traditional constant temperature fluid bath generally adopts electrical heating elements liquid towards medium to heat, and the intensification response can be very fast, but temperature-fall period only leans on natural heat dissipation, can't artificially control, and the result makes the transient process that reaches warm of calibrating requirement very long.Thereby the calibrating that makes temperature element becomes poor efficiency, consuming time, power consumption and is out of favour, high-speed, high-quality that can not adapt to especially that modern industry produces and requirement cheaply.
Summary of the invention
The objective of the invention is to design a kind of automatic constant temperature fluid bath that the liquid bath temperature can be controlled in the effective range.
In order to achieve the above object, the present invention adopts following technical solution: a kind of automatic constant temperature fluid bath, comprise liquid bath, conduction oil, the liquid bath heating system, automatic temperature controller and be arranged on temperature sensor in the liquid bath, the temperature sensor data output end is connected with the automatic temperature controller data input pin, it is characterized in that it also contains liquid bath water cooling cooling system and cooling water tank, liquid bath water cooling cooling system is made of hydrocooler and cooling-water pump, hydrocooler is arranged in the liquid bath, the hydrocooler input end is connected with cooling water tank by cooling-water pump, and the hydrocooler output terminal is connected with cooling water tank.
Owing to be provided with liquid bath water cooling cooling system in liquid bath, when conduction oil temperature in the liquid bath surpassed setting value, liquid bath water cooling cooling system carried out the forced fluid cooling to conduction oil, thereby the liquid bath temperature is controlled in the effective range.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a present embodiment structural principle synoptic diagram.
Embodiment
As shown in the figure, present embodiment comprises liquid bath 6, conduction oil 3, liquid bath heating system 4, water tank cooling refrigeration system 9,11, liquid bath water cooling cooling system 8,12, automatic temperature controller 1 and is arranged on the temperature sensor 7 in the liquid bath and is arranged on the interior temperature sensor 10 of cooling water tank.Wherein, described water tank cooling refrigeration system is made of refrigerator 11, cooling water tank 9, and refrigerator 11 is located on the cooling water tank 9; Described liquid bath water cooling cooling system is made of hydrocooler 12 and cooling-water pump 8, and hydrocooler 12 is arranged in the liquid bath 6, and hydrocooler 12 input ends are connected with cooling water tank 9 by cooling-water pump 8, and hydrocooler 12 output terminals are connected with cooling water tank 9; The data output end of temperature sensor 7,10 is connected with automatic temperature controller data input pin A, B respectively, and temperature controller output terminal C, D are connected with cooling-water pump 8, refrigerator 11 control ends respectively.
When liquid bath is set the temperature of heating when higher than current groove temperature, begin to heat up, start liquid bath heating system 4 by automatic temperature controller 1, the temperature of conduction oil 3 is constantly raise, simultaneous temperature sensor 7 is sent to automatic temperature controller 1 with current liquid bath temperature in real time, compare with setting heating-up temperature value, when the groove temperature is higher than setting heating-up temperature value, by automatic temperature controller 1 start signal output liquid bath water cooling cooling system 8,12, under the drive of cooling-water pump 8, liquid coolant 9 circular flows are constantly taken the heat of conduction oil 3 out of through hydrocooler 12, move in circles, the groove temperature is just reduced fast.
Because in temperature-fall period, liquid coolant constantly absorbs the heat of conduction oil 3 in the liquid bath, and the temperature of liquid coolant is constantly raise.When coolant temperature surpasses the temperature value of liquid coolant setting, temperature sensor 10 is issued automatic temperature controller 1 with the coolant temperature data-signal, by automatic temperature controller 1 start signal output refrigerator 11, liquid coolant is freezed, and make the temperature of liquid coolant be lower than the monitoring value that sets.
In sum, the present invention compared with prior art has the following advantages:
1, cooling rate is fast, has improved nearly 20 times than naturally lowering the temperature.
2, improved the calibrating efficient of temperature element.
3, response is fast.
