It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The technical solution of the present invention is further explained with reference to fig. 1 and fig. 2 as follows:
as shown in fig. 1, the automatic circulating water regulation and control system comprises: a water replenishing tank 10 for replenishing water to a circulating water pipeline, a cooling device 11 (specifically comprising a cooling tower fan and a spray pump) for cooling the circulating water, a softened water filtering device 12 for supplying softened water to the circulating water and a control cabinet 13; wherein, the cabinet body of the control cabinet 13 is provided with a human-computer interface 131 and an automatic adjustment control circuit (as shown in fig. 2) arranged in the cabinet body, the cooling device 11, the softened water filtering device 12 and the human-computer interface 131 are respectively electrically connected to the automatic adjustment control circuit, and the regulation and control of the water replenishing tank 10, the cooling device 11 and the softened water filtering device 12 are realized based on the human-computer interface 131 and the automatic adjustment circuit. The device without model limitation in this embodiment may be a conventional device.
As shown in fig. 2, the automatic regulation control circuit includes the controller, the soft water pump package of being connected with the controller electricity, level sensor, the water pump package, pressure sensor and temperature sensor, wherein, the soft water pump package is used for controlling the intaking of soft water in the moisturizing case, level sensor sets up the bottom half at the moisturizing case, temperature sensor sets up on circulating water pipeline, a return water temperature for detecting circulating water pipeline, the control of temperature in the entire system support pipeline, the control of soft water pump, the control and the interlock of water supply pressure report to the police, concrete process is as follows:
1. control of water temperature in a pipeline
Through setting up the temperature sensor on circulating water pipeline's wet return, the temperature in the real-time detection pipeline, and give the controller with 4-20mA signal of telecommunication to this temperature and calculate, the controller receives the liquid level signal and through data processing back, the start-up and the stop of control cooling tower fan, when the temperature is higher than the setting value upper limit, and the switch of cooling tower fan is in the automatic control position, the cooling tower fan starts, when the temperature is less than the setting temperature value lower limit, and the switch of cooling tower fan is in the automatic control position, the cooling fan stops.
2. Control of soft water pump
The liquid level of the water tank is detected in real time through a liquid level sensor at the bottom of the water replenishing tank, the liquid level is transmitted to the controller for calculation through a 4-20mA electric signal, and the controller controls the start and stop of the soft water pump after receiving the liquid level signal and performing data processing. Specifically, when the liquid level is lower than the lower limit of the set value and the switch of the soft water pump is in the automatic control position, the soft water pump is started, and when the liquid level is higher than the upper limit of the set value and the switch of the soft water pump is in the automatic control position, the soft water pump is stopped. The soft water pump adopts a one-use-one-standby control mode, when the standby selector switch is in the '1-use' position, the soft water pump 1 automatically operates according to the liquid level, and when the standby selector switch is in the '2-use' position, the soft water pump 2 automatically operates according to the liquid level.
3. Control of water supply pressure
At the beginning of starting the system, the outlet of the water pump has no pressure, the signal transmitted to the controller by the pressure sensor is very small, after PID calculation, the water pump runs at a higher speed, the pressure of the pipeline is rapidly increased, the rotating speed of the water pump is gradually reduced along with the gradual approach of the pressure to a set value, the balanced rotating speed for maintaining the pressure is reached, and then the rotating speed is kept to run. When the water consumption is too large, the rotating speed of the water pump can be gradually increased, and when the rotating speed of the water pump is increased to the rated rotating speed, the set pressure can not be reached, the system automatically starts the second water pump, and the two water pumps work simultaneously to supply water to a workshop. When the water consumption is too low, the rotating speeds of the two water pumps are reduced at the same time, if the two frequency converters run at a lower speed for a long time, the system cuts off one water pump automatically, and a single water pump supplies water to a workshop. If a single long-time water pump can meet the water supply pressure, the system can automatically switch the water pump to another water pump to operate according to the set time, and the operation is circulated.
4. Systematic interlock alarm
When the system detects that the pressure of the circulating pipeline is higher than the set upper pressure limit, the water pump is automatically stopped to work, and when the water pump breaks down in the running process, the other water pump is automatically started and gives out an audible and visual signal for alarming.
The whole system is reasonable in design, intelligent automatic regulation and control of all equipment in the circulating water system are achieved, relevant personnel can regulate and control the equipment in the circulating water system through the human-computer interface on the control cabinet, states of all the equipment can be monitored in time, the whole regulation and control process is mastered, and the intelligent automatic regulation and control system is very convenient.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
