Priority date (The priority date is an assumption and iTagPro website is not a legal conclusion. The invention discloses an clever hydraulic balance management system machine primarily based on a datum level monitoring methodology. The management gadget consists of: the system includes a predominant station controller, a variable-frequency water pump set controller, a cold and heat supply controller and water terminal controllers. Each controller is linked with every corresponding system. Each controller is a subject control unit, and is linked with the grasp station controller to kind a DCS computer network control system. The controller of the variable-frequency water pump set tracks the most unfavorable finish, particularly the whole load change of the system in real time on the minimum value; whereas other controllers management the respective devices to track the respective finish load changes in real time at minimal value; under the coordinated management of the grasp station controller, all the devices of the water circulation system operate based on the rule of 'actual-time load monitoring and minimum cost', ItagPro specifically the intelligent perform of self-adaption and minimum power consumption.
Thus, the system is in an integrally optimized dynamic hydraulic stability state intelligently all the time, and the best goal of supplying water on demand at the minimal cost is achieved by every water use end. The invention relates to the sphere of hydraulic stability management of a water circulation system. The water circulation system is broadly utilized in the production and life of workers and other people, iTagPro features but the problem of hydraulic imbalance affecting the security, the operation efficiency and the quality of the water circulation system is always plagued in the trade; the hydraulic imbalance is the phenomenon that each end of the system doesn't have the perform of supplying water in line with the need, in order that the chilly and hot of every end of the system are uneven, the security is reduced, the vitality consumption is increased, and the operation high quality is lowered; because the typical discount idea, iTagPro features linear considering, stacking and stacking integrated scientific paradigm and the nonlinear complicated water circulation system are not matched in nature, the formed water circulation system is just not caused by an inherent healthy structure.
The traditional technique for fixing the hydraulic imbalance is to put in a steadiness valve on a important pipe and a department pipe of a water circulation system. There are two kinds of balancing valves: constant circulation type stability valve and fixed pressure sort balance valve. While the inner structure and the intrinsic operation rule of the water circulation system and the roles and capabilities of the steadiness valves within the system and the adjustments of the overall performance of the system usually are not quite clear for builders of the stability valves, the developed stability valves can remedy the issue of hydraulic balance, but carry different problems, as shown in fig. 1 and 2, the stability valves are put in on each branch pipe, ItagPro each principal pipe and each fundamental pipe, the steadiness valves are greatly complicated, iTagPro features each steadiness valve is manually adjusted to the designed circulation through the use of expensive special devices, the method is sophisticated, the adjusted circulation is barely the designed worth but not the precise value, and the distinction of two values at completely different ends can also be totally different, so that the accuracy of the stream adjustment can be completely different; meanwhile, the constant current and fixed strain efficiency of the stability valve is changed by consuming 20% -30% of the conveying power of the water pump, and the issues are opposite to the original purposes of hydraulic steadiness vitality saving and operation high quality enchancment design, in order that popularization and utility of the balance valve are restricted.
Therefore, the standard stability valve has advanced construction, very advanced construction for forming a hydraulic steadiness adjusting system, excessive manufacturing price, tough manual debugging, low power saving efficiency and the like. The invention aims to supply an intelligent hydraulic balance management system system by a datum point tracking technique, which aims to solve the issues of excessive manufacturing price, troublesome guide debugging, low vitality-saving effectivity and iTagPro portable the like of a standard hydraulic stability adjusting system. The variable-frequency water pump set controller, the cold and sizzling supply controllers and the water terminal controllers are subject control units and are related with the grasp station controller by means of a field management bus to kind a DCS computer community management system; the grasp station controller is used for receiving the corresponding tools operation information uploaded by each discipline control unit and sending a coordinated operation control instruction of the DCS computer community management system to every area control unit, in order that the DCS computer network management system, every field management unit and all tools operate based on the rule of 'real-time load tracking and minimal cost'.
