Priority date (The precedence date is an assumption and is not a legal conclusion. The invention discloses an clever hydraulic stability management system device primarily based on a datum level monitoring method. The management system consists of: the system contains a essential station controller, a variable-frequency water pump set controller, a cold and heat supply controller and water terminal controllers. Each controller is connected with each corresponding device. Each controller is a discipline control unit, and is linked with the grasp station controller to form a DCS laptop community control system. The controller of the variable-frequency water pump set tracks probably the most unfavorable end, particularly the full load change of the system in real time at the minimum price; while different controllers management the respective devices to track the respective finish load adjustments in real time at minimal value; under the coordinated control of the grasp station controller, all the units of the water circulation system operate in line with the rule of 'actual-time load tracking and minimal value', particularly the clever operate of self-adaption and minimal energy consumption.
Thus, the system is in an integrally optimized dynamic hydraulic stability state intelligently all the time, and the ideal aim of supplying water on demand at the minimum value is achieved by every water use end. The invention relates to the field of hydraulic stability control of a water circulation system. The water circulation system is widely utilized within the manufacturing and life of workers and itagpro locator folks, however the issue of hydraulic imbalance affecting the safety, the operation efficiency and the standard of the water circulation system is all the time plagued within the industry; the hydraulic imbalance is the phenomenon that each finish of the system doesn't have the function of supplying water in line with the need, in order that the chilly and scorching of each end of the system are uneven, the safety is diminished, the vitality consumption is increased, and the operation high quality is diminished; because the typical discount theory, linear thinking, stacking and stacking built-in scientific paradigm and the nonlinear complex water circulation system are usually not matched in nature, the formed water circulation system is just not caused by an inherent healthy construction.
The normal technique for fixing the hydraulic imbalance is to install a stability valve on a primary pipe and a department pipe of a water circulation system. There are two forms of balancing valves: constant flow type steadiness valve and constant pressure sort stability valve. While the interior construction and the intrinsic operation rule of the water circulation system and the roles and features of the balance valves in the system and the adjustments of the general efficiency of the system usually are not fairly clear for developers of the stability valves, the developed steadiness valves can remedy the issue of hydraulic stability, however bring different issues, as proven in fig. 1 and 2, the balance valves are installed on every branch pipe, each foremost pipe and each most important pipe, the steadiness valves are tremendously sophisticated, each balance valve is manually adjusted to the designed flow by using costly special devices, the process is sophisticated, the adjusted flow is simply the designed worth however not the precise worth, and the distinction of two values at totally different ends can be different, in order that the accuracy of the circulation adjustment can also be different; in the meantime, the fixed current and constant strain efficiency of the steadiness valve is modified by consuming 20% -30% of the conveying power of the water pump, and the issues are contrary to the original purposes of hydraulic steadiness vitality saving and operation high quality enchancment design, in order that popularization and utility of the steadiness valve are restricted.
Therefore, the normal steadiness valve has complex structure, very complicated construction for forming a hydraulic balance adjusting system, excessive manufacturing cost, difficult handbook debugging, low power saving effectivity and the like. The invention goals to provide an clever hydraulic stability management system system by a datum level tracking technique, which aims to solve the problems of excessive manufacturing cost, tough manual debugging, low vitality-saving efficiency and the like of a traditional hydraulic balance adjusting system. The variable-frequency water pump set controller, the chilly and scorching supply controllers and the water terminal controllers are subject control items and are linked with the master station controller by way of a field control bus to type a DCS laptop network management system; the grasp station controller is used for receiving the corresponding gear operation data uploaded by each subject control unit and itagpro locator sending a coordinated operation management instruction of the DCS pc network management system to each subject management unit, so that the DCS laptop network control system, every area control unit and all gear function in response to the rule of 'real-time load monitoring and minimal value'.
