The technical scheme in the invention for solving the above technical problem is: this water cooling unit recirculated water control device, it is characterized in that: comprise controller, water circulating pump, pressure transducer and frequency converter, described controller and pressure transducer are electrically connected, this controller and frequency converter are electrically connected, described frequency converter and water circulating pump are electrically connected, and described temperature sensor and controller are electrically connected.
Controller described in the utility model is single-chip microcomputer.
Controller described in the utility model is PLC.
The quantity of water circulating pump described in the utility model can be one, two or three, and all water circulating pumps all are electrically connected with frequency converter.
The utility model compared with prior art, have the following advantages and effect: automaticity is high, energy savings, control accuracy is high, and is easy to use and reliable, equipment volume is little, and is convenient for installation and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Label declaration: controller 1, water circulating pump 2, pressure transducer 3, temperature sensor 4, frequency converter 5, circulating water pipe 6.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1, the water cooling unit recirculated water control device of the present embodiment comprises controller 1, water circulating pump 2, pressure transducer 3, temperature sensor 4 and frequency converter 5.
In the present embodiment, the quantity of water circulating pump 2 is one, and water circulating pump 2 is installed on the circulating water pipe 6.Water circulating pump 2 and frequency converter 5 are electrically connected.In the utility model, the quantity of water circulating pump 2 can be one, two or three, and water circulating pump 2 all is electrically connected with frequency converter 5.
Pressure transducer 3 is installed in the circulating water pipe 6, and pressure transducer 3 can be measured the pressure of circulating water pipe 6, and this pressure is transformed into digital signal transfers to controller 1.Controller 1 and pressure transducer 3 are electrically connected, and controller 1 and frequency converter 5 are electrically connected, and in the present embodiment, controller 1 is single-chip microcomputer; In the utility model, controller 1 can be the opertaing devices such as PLC or CPU.
Temperature sensor 4 is installed in the workshop, the temperature in the monitoring workshop, and temperature sensor 4 and controller 1 are electrically connected, and then the temperature data that temperature sensor 4 gathers in the workshop passes to controller 1.
When the utility model uses, the temperature in the temperature sensor 4 induction workshops, and with workshop temperature and controller 1 interior preset temperature comparison.If the workshop temperature is higher than preset temperature, then 5 actions of controller 1 control frequency converter improve water circulating pump 2 revolutions, increase the flow of recirculated water, reduce the workshop temperature.If the workshop temperature is lower than preset temperature, then 5 actions of controller 1 control frequency converter reduce water circulating pump 2 revolutions, reduce circulating water flow, improve the workshop temperature.
Pressure in the pressure transducer 3 induction circulating water pipes 6; when this pressure surpassed controller 1 interior pre-set force value, controller 1 starting protection program was so that water circulating pump 2 can not improve rotating speed again; guarantee that the pressure in the circulating water pipe 6 is lower than predefined pressure, guarantees safety.
Above content described in this instructions only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
