Abstract
A water level and water pressure control method is provided; firstly a water level and water pressure control system is set up, and comprises a water pump, a pipeline, a valve, and a water tank or a pressure tank; an electric control cabinet controls the water pump to work; the water pump is connected with the pipeline, the valve, the water tank or the pressure tank; the water level and pressure control method is combined with other steps and methods so as to solve the problems that the conventional system is large in primary investment, high in equipment and running cost, and complex in mounting and maintenance.
Description
Technical field
The invention belongs to the control of water level and hydraulic pressure, draining, irrigation and sewerage treatment, the water level of fire-fighting and the technical field of hydraulic pressure, be specifically related to the control method of a kind of water level and hydraulic pressure.
Background technology
Current water level and the control method of hydraulic pressure, generally adopt water pump water tank associating water supply modes: water pump absorbs water from reservoir, after pressurization, send into water tank.Because the controlled quentity controlled variable of water pump water level and hydraulic pressure is greater than system water amount, cistern water level rises, and to termination of pumping during high water level, restarts when low water stage.Such water pump and water tank associated working, water pump, in time to water tank water-filling, can reduce water tank capacity.Meanwhile, under the adjustment of water tank, water pump can be stabilized in high-efficiency point work, saves power consumption.High level cistern adopts level relay control starting mode of pump, be easy to realize management automation.Reservoir and water tank can lay in certain water yield, strengthen the security reliability of the control of water level and hydraulic pressure.
But such system one-time investment is comparatively large, equipment and operating cost higher, install and safeguard cumbersome.
Summary of the invention
Object of the present invention provides the control method of a kind of water level and hydraulic pressure, first the control system of water level and hydraulic pressure is built, the control system ingredient of this water level and hydraulic pressure comprises water pump, pipeline, valve, water tank or air pressure tank, the work of water pump is controlled by electrical control cubicles, water pump connecting pipe, valve, water tank or air pressure tank, and it is comparatively large to avoid the system one-time investment of prior art in conjunction with other step method, equipment and operating cost higher, install and safeguard cumbersome defect.
In order to overcome deficiency of the prior art, the invention provides the solution of the control method of a kind of water level and hydraulic pressure, specific as follows:
A control method for water level and hydraulic pressure, step is as follows:
Step 1: the control system first building water level and hydraulic pressure, the control system ingredient of this water level and hydraulic pressure comprises water pump, pipeline, valve, water tank or air pressure tank, is controlled the work of water pump, water pump connecting pipe, valve, water tank or air pressure tank by electrical control cubicles;
Step 2: SBR, namely priming level detector and hydraulic pressure detector sensed water level signal and hydraulic signal respectively, then drives water pump according to water level signal and hydraulic signal in conjunction with fuzzy PID algorithm;
Step 3: drive water pump according to demand adjustment water level.
Described water level detection gauge includes level sensor.
Present invention incorporates the control system first building water level and hydraulic pressure, the control system ingredient of this water level and hydraulic pressure comprises water pump, pipeline, valve, water tank or air pressure tank, the work of water pump is controlled, water pump connecting pipe, valve, water tank or air pressure tank by electrical control cubicles; SBR, namely priming level detector and hydraulic pressure detector sensed water level signal and hydraulic signal respectively, then drives water pump according to water level signal and hydraulic signal in conjunction with fuzzy PID algorithm; Drive water pump according to demand adjustment water level.The system one-time investment avoiding prior art is comparatively large, equipment and operating cost higher, install and safeguard cumbersome defect.

Fig. 1 is control structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, summary of the invention is described further:
With reference to shown in Fig. 1, the control method of water level and hydraulic pressure, step is as follows:
Step 1: the control system first building water level and hydraulic pressure, the control system ingredient of this water level and hydraulic pressure comprises water pump, pipeline, valve, water tank or air pressure tank, is controlled the work of water pump, water pump connecting pipe, valve, water tank or air pressure tank by electrical control cubicles;
Step 2: SBR, namely priming level detector and hydraulic pressure detector sensed water level signal and hydraulic signal respectively, then drives water pump according to water level signal and hydraulic signal in conjunction with fuzzy PID algorithm;
Step 3: drive water pump according to demand adjustment water level.Described water level detection gauge includes level sensor.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to technical spirit of the present invention, within the spirit and principles in the present invention, to any simple amendment that above embodiment is done, equivalent replacement and improvement etc., within the protection domain all still belonging to technical solution of the present invention.
