The utility model discloses the temperature signal that the cooling water temperature sensor detected, output control cooling tower cooling fan's operation is handled in be used for cooling water set cold operation controlling means's design through temperature controller to reach the purpose of control cooling temperature degree, keep the cooling water at 22 -25 DEG C, supply with the cooling water set and establish normal work oil pressure, ensured that the cooling water set can move reliably.
Description
Technical field
The utility model relates to domain of control temperature, particularly relates to a kind of for handpiece Water Chilling Units cold operation control device.
Background technology
As everyone knows; handpiece Water Chilling Units all can be used to provide cold water in general enterprises; but existing handpiece Water Chilling Units is shut down lower than can produce protectiveness when 22 DEG C because compressor oil pressure does not reach service requirement in environment temperature; thus cause the humiture needed for enterprise's production to be in runaway condition; finally cause enterprise product quality dissatisfaction, cause the economic loss that enterprise is unnecessary.
Utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of reliable, adapt to cold operation for handpiece Water Chilling Units cold operation control device.
One of the present utility model is used for handpiece Water Chilling Units cold operation control device, comprise cooling pond and temperature controller, the input of described cooling pond connects cooling tower, the output of described cooling pond connects condenser, described cooling pond is provided with temperature sensor, described cooling pond is connected by described temperature sensor with temperature controller, and the cooling fan of described cooling tower is controlled by temperature controller.
Further, be provided with change-over switch in winter in summer in the control circuit of described temperature controller, when environment temperature is greater than 25 DEG C, described winter in summer, change-over switch was stopped using.
Further, the water temperature value of described cooling pond is 22-25 DEG C.
Further, described temperature controller is digital display type temperature controller, and the temperature controlling range of described temperature controller is at 0-100 DEG C, and described temperature controller adopts relay contact output type.
By such scheme, the utility model at least has the following advantages: the temperature signal detected by temperature controller process cooling-water temperature sensor, export the operation of controlled cooling model tower cooling fan, thus reach the object of controlled cooling model coolant-temperature gage, keep cooling water at 22-25 DEG C, feeding cold water unit sets up normal operating oil pressure, ensure that handpiece Water Chilling Units can reliably be run.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 1-2, for handpiece Water Chilling Units cold operation control device, comprise cooling pond 1 and temperature controller 5, the input of cooling pond 1 connects cooling tower 2, the output of cooling pond 1 connects condenser 3, cooling pond 1 is provided with temperature sensor 4, cooling pond 1 is connected by temperature sensor 4 with temperature controller 5, and the cooling fan 7 of cooling tower 2 is controlled by temperature controller 5.Be provided with change-over switch 8 in winter in summer in the control circuit 6 of temperature controller 5, when environment temperature is greater than 25 DEG C, winter in summer, change-over switch 8 was stopped using.The water temperature value of cooling pond 1 is 22-25 DEG C.Temperature controller 5 is digital display type temperature controller, and the temperature controlling range of temperature controller 5 is at 0-100 DEG C, and temperature controller 5 adopts relay contact output type.
In real work, temperature sensor 4 is for detecting the water temperature in cooling pond 1, and the cooling water Current Temperatures detected is fed back to temperature controller 5, temperature controller 5 processes the temperature signal sent, the relay of temperature controller 5 inside carries out control by the data after process to the cooling fan 7 in cooling tower 2 and exports, control the unlatching situation of cooling fan 7, thus complete the control to cooling water temperature.Before using, can set temperature controller 5, select the temperature value controlled according to actual conditions, this ensures that there the requirement of handpiece Water Chilling Units cooling water under cold operation.
Add change-over switch 8 in winter in summer in the control circuit 6 of temperature controller 5, according to the autonomous change-over circuit of varying environment situation, practicality can be had more, when environment temperature is higher than 25 DEG C, stop using change-over switch 8 in this in winter in summer.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
The above is only preferred embodiment of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
