Description
Technical field
The utility model relates to a kind of cooling tower technical field, particularly relates to a kind of energy-saving control system of cooling tower.
Background technology
At present, the power source that the blower fan of cooling tower drives has two kinds, and one is that motor drives, and another kind is that the hydraulic turbine drives.Motor drives power consumption large, is unfavorable for energy-conservation; The hydraulic turbine drives this mode to be utilize the power surplus of recirculated water to do work, power consumption is few compared with motor, but still need to water circulating pump uninterrupted power supply, and easily occurring that circulation power surplus is not enough, such hydraulic turbine power output causes the problem of fault with regard to the power requirement that can not meet blower fan.
Utility model content
For above technical problem, the utility model provides a kind of energy-saving control system of cooling tower, can according to the turnover water temperature regulable control circulating pump of cooling tower, more energy-conservation, safety and stability more.
To this, the technical solution of the utility model is:
A kind of energy-saving control system of cooling tower, comprise the hydraulic turbine, master controller, frequency converter, water circulating pump, described frequency converter is connected with water circulating pump, master controller respectively, the described hydraulic turbine is provided with feed pipe and return pipe, described feed pipe is provided with the first temperature inductor be connected with master controller, frequency converter, described return pipe is provided with the second temperature inductor be connected with master controller, frequency converter, be provided with temperature difference protection controller between described first temperature inductor and the second temperature inductor, described temperature difference protection controller is connected with master controller; Described feed pipe is connected with needing the one end of the equipment cooled through water circulating pump, and described return pipe is connected with needing the other end of the equipment cooled.
As further improvement of the utility model, the quantity of described water circulating pump is three, and described three water circulating pumps are connected in parallel.
As further improvement of the utility model, the two ends of described water circulating pump are equipped with valve.
As further improvement of the utility model, in described feed pipe, be provided with filter.
As further improvement of the utility model, described temperature difference protection controller is provided with warning device.Adopt this technical scheme, when the temperature difference in feed pipe and return pipe has exceeded the temperature difference of setting, warning device just can be reported to the police, and like this, better can run by protected host, also more easily find fault when machine is out of order.
As further improvement of the utility model, described master controller is provided with touch display screen.
As further improvement of the utility model; described feed pipe is provided with the first pressure inductor; described return pipe is provided with the second pressure inductor, is provided with differential pressure security controller between described first pressure inductor and the second pressure inductor, and described differential pressure security controller is connected with master controller.
As further improvement of the utility model, described first temperature inductor is located at the arrival end of described feed pipe; Described second temperature inductor is located at the port of export of described outlet pipe.
Compared with prior art, the beneficial effects of the utility model are:
The first, adopt the technical solution of the utility model, instead of motor with the hydraulic turbine, reach energy-conservation; Simultaneously by having installed frequency converter additional to circulating pump, frequency converter carrys out the frequency conversion of controlled circulation water pump according to the difference of the water temperature of feed pipe and return pipe, thus reaches the effect of secondary energy-saving.
The second, by adding fixed filter at feed pipe, make the impurity in water less, the cleaning frequency is longer, decreases maintenance expense.
3rd, by arranging temperature difference protective device, the temperature difference having exceeded setting when the import and export temperature difference just can be reported to the police, and like this, better can run by protected host, also more easily find fault when machine is out of order.
