Abstract
The utility model discloses a tap water time sharing partial pressure system. A closed loop is connected with a water pump which is used for supplying pressure to a tap water pipeline. The closed loop comprises a pressure sensor which is arranged at an output end of the water pump, a signal output end of the pressure sensor is connected with a programmable logic controller (PLC), and after the PLC conducts comparing according to actual pressure value which is fed back by the pressure sensor and pressure value which is set in a current time period, the PLC transmits a signal to a frequency conversion controller which is used for adjusting rotating speed of the water pump. The tap water time sharing partial pressure system can automatically change the amount of water supplying of different time periods so as to achieve the aims that electricity is saved, water is saved, and equipment loss is reduced. The tap water time sharing partial pressure system is small in investment and simple in implementation. With the system, on-site operating persons are not needed, the operating persons can just conduct once polling for equipment, and the tap water time sharing partial pressure system has the advantages of being stable in water supplying pressure and water quality.
Description
Technical field
The utility model relates to a kind of waterpower and detects control system, is specifically related to a kind of tap water timesharing voltage divider system that can regulate according to different period water supply volumes variations control.
Background technology
In modern science and technology and field, automatic control technology more and more plays a key effect, and along with the development of science and production technology, the levels of automatic technology is also more and more higher.In traditional tap water variable frequency control field, control system is comprised of PLC module, control module, display module etc. mostly, this control system exists the defectives such as complex circuit, fault rate height, also can't change the control that automatically adjusts according to different period water supply volumes simultaneously, so the purpose that can not effectively reach energy-saving and cost-reducing, reduce network of rivers loss.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of tap water timesharing voltage divider system that can change according to different period water supply volumes the control that automatically adjusts is provided.
A kind of tap water timesharing voltage divider system, closed loop is connected to for the water pump to the tap water pipe line voltage supply, comprise the pressure sensor that is arranged on the water pump output, the signal output part of described pressure sensor is connected on the PLC controller, after the force value that the actual pressure value that the PLC controller feeds back according to pressure sensor and current slot are set compares, signal is passed to for the frequency-variable controller of adjusting pump rotary speed.
Also be connected with liquid level sensor between described water pump output and the PLC controller, after the level value that the actual liquid level value that the PLC controller feeds back according to liquid level sensor and current slot are set compares, signal is passed to for the frequency-variable controller of adjusting pump rotary speed.
Described water pump is provided with the manually hand regulator of its adjusting rotary speed.
Described frequency-variable controller is connected electrically in and calculates on the display unit.
The utility model is according to the difference of different period water supply volumes, and the output of different periods capable of automatic changing is to reach using electricity wisely, the purpose of using water wisely and minimizing equipment loss.And small investment, implement simply, do not need the site operation personnel after adopting native system, equipment is is once patrolled and examined every day get final product, and have pressure of supply water and stablize the advantage of water stabilization.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only for explanation the present invention but not for limiting the scope of the invention.
Embodiment 1
Referring to Fig. 1, a kind of tap water timesharing voltage divider system that the utility model provides, closed loop is connected to for the water pump to the tap water pipe line voltage supply, comprise the pressure sensor that is arranged on the water pump output, the signal output part of described pressure sensor is connected on the PLC controller, after the force value that the actual pressure value that the PLC controller feeds back according to pressure sensor and current slot are set compares, signal is passed to for the frequency-variable controller of adjusting pump rotary speed, when pressure is higher than the target setting value, reduce pump power, reduce pushing quantity; When pressure is lower than the target setting value, increase the source pump power, increase pushing quantity.
Embodiment 2
The difference of present embodiment and embodiment 1 is: also be connected with liquid level sensor between described water pump output and the PLC controller, when the PLC controller detects the liquid level of being fed back by liquid level sensor and is higher than the target setting value, the water pump normal operation, liquid level is lower than the target setting value, and water pump quits work.
Embodiment 3
Present embodiment and embodiment 1,2 difference are: for fear of when native system breaks down, can't realize automatic control, so can increase hand regulator at water pump, can be to the controlling of pump rotary speed by the operation hand regulator, assure feed water is stable.
Embodiment 4
Described frequency-variable controller can be connected electrically in and calculate on the display unit, calculate display unit can with field device communicating, carry out data acquisition, analyze, control the operation of each equipment with optimized scheme, and carry out the data storage, and optimize and fault inquiry in order to carry out the equipment operation in the future, realize full-automatic.
Claims (4)
1. tap water timesharing voltage divider system, it is characterized in that: this system's closed loop is connected to for the water pump to the tap water pipe line voltage supply, comprise the pressure sensor that is arranged on the water pump output, the signal output part of described pressure sensor is connected on the PLC controller, after the force value that the actual pressure value that the PLC controller feeds back according to pressure sensor and current slot are set compares, signal is passed to for the frequency-variable controller of adjusting pump rotary speed.
2. tap water timesharing voltage divider system according to claim 1, it is characterized in that: also be connected with liquid level sensor between described water pump output and the PLC controller, after the level value that the actual liquid level value that the PLC controller feeds back according to liquid level sensor and current slot are set compares, signal is passed to for the frequency-variable controller of adjusting pump rotary speed.
