Priority date (The precedence date is an assumption and isn't a authorized conclusion. The invention discloses an clever hydraulic steadiness control system gadget based mostly on a datum level tracking method. The control device contains: the system contains a primary 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 connected with the master station controller to form a DCS pc network control system. The controller of the variable-frequency water pump set tracks the most unfavorable end, particularly the whole load change of the system in real time at the minimal value; while other controllers management the respective gadgets to track the respective finish load modifications in actual time at minimal value; beneath the coordinated control of the master station controller, all of the gadgets of the water circulation system operate in line with the rule of 'real-time load tracking and minimal value', particularly the clever function of self-adaption and minimum energy consumption.



Thus, the system is in an integrally optimized dynamic hydraulic balance state intelligently on a regular basis, and the perfect aim of supplying water on demand on the minimum price is achieved by each water use end. The invention pertains to the sector of hydraulic stability control of a water circulation system. The water circulation system is broadly applied in the production and life of staff and other people, but the problem of hydraulic imbalance affecting the security, the operation effectivity and the standard of the water circulation system is at all times plagued within the trade; the hydraulic imbalance is the phenomenon that every finish of the system doesn't have the perform of supplying water in response to the necessity, in order that the cold and hot of every finish of the system are uneven, the safety is lowered, the power consumption is increased, and the operation high quality is lowered; because the standard reduction idea, linear pondering, stacking and stacking integrated scientific paradigm and the nonlinear complicated water circulation system aren't matched in nature, the formed water circulation system just isn't attributable to an inherent wholesome construction.



The normal methodology for solving the hydraulic imbalance is to put in a balance valve on a principal pipe and a department pipe of a water circulation system. There are two sorts of balancing valves: fixed circulate type stability valve and constant strain type balance valve. While the inner structure and iTagPro key finder the intrinsic operation rule of the water circulation system and the roles and functions of the steadiness valves within the system and the adjustments of the general efficiency of the system aren't quite clear for builders of the balance valves, the developed steadiness valves can solve the issue of hydraulic balance, however convey different issues, as proven in fig. 1 and 2, the stability valves are installed on every branch pipe, every essential pipe and each fundamental pipe, the balance valves are vastly difficult, each steadiness valve is manually adjusted to the designed movement by using costly particular devices, the process is difficult, iTagPro key finder the adjusted circulate is barely the designed worth but not the actual worth, and the difference of two values at completely different ends is also totally different, so that the accuracy of the movement adjustment can also be totally different; in the meantime, the fixed present and constant pressure efficiency of the stability valve is modified by consuming 20% -30% of the conveying power of the water pump, and the problems are contrary to the original purposes of hydraulic balance vitality saving and operation quality improvement design, so that popularization and software of the balance valve are restricted.



Therefore, the standard steadiness valve has complicated structure, very complicated construction for forming a hydraulic stability adjusting system, excessive manufacturing price, tough handbook debugging, low energy saving efficiency and the like. The invention aims to supply an clever hydraulic balance control system machine by a datum point monitoring method, which goals to solve the issues of high manufacturing cost, difficult guide debugging, low power-saving efficiency and the like of a conventional hydraulic steadiness adjusting system. The variable-frequency water pump set controller, the cold and scorching supply controllers and the water terminal controllers are area management items and are connected with the grasp station controller by way of a discipline management bus to kind a DCS computer network management system; the grasp station controller is used for receiving the corresponding gear operation information uploaded by each area management unit and sending a coordinated operation control instruction of the DCS laptop community management system to every area management unit, so that the DCS computer network control system, each subject control unit and all tools operate in accordance with the rule of 'real-time load monitoring and minimal cost'.
