Priority date (The priority date is an assumption and isn't a legal conclusion. The invention discloses an intelligent hydraulic stability management system system based mostly on a datum point tracking technique. The management gadget contains: the system contains a most important station controller, a variable-frequency water pump set controller, a cold and iTagPro technology heat source controller and water terminal controllers. Each controller is related with each corresponding machine. Each controller is a area management unit, and is linked with the master station controller to type a DCS computer community control system. The controller of the variable-frequency water pump set tracks essentially the most unfavorable finish, particularly the overall load change of the system in real time on the minimal price; while different controllers management the respective units to trace the respective finish load modifications in real time at minimal price; under the coordinated control of the master station controller, all the gadgets of the water circulation system operate in response to the rule of 'real-time load tracking and minimal price', namely the intelligent perform 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 perfect intention of supplying water on demand at the minimal price is achieved by each water use finish. The invention pertains to the sector of hydraulic balance control of a water circulation system. The water circulation system is widely applied in the production and life of employees and folks, but the problem of hydraulic imbalance affecting the security, the operation effectivity and the standard of the water circulation system is always plagued in the industry; the hydraulic imbalance is the phenomenon that every finish of the system doesn't have the perform of supplying water based on the necessity, in order that the cold and iTagPro features sizzling of every end of the system are uneven, iTagPro bluetooth tracker the security is diminished, the power consumption is increased, and the operation high quality is reduced; as a result of the conventional discount idea, linear pondering, 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 brought on by an inherent healthy construction.
The traditional technique for fixing the hydraulic imbalance is to put in a steadiness valve on a essential pipe and a branch pipe of a water circulation system. There are two types of balancing valves: fixed movement type balance valve and fixed pressure sort balance valve. While the internal structure and the intrinsic operation rule of the water circulation system and the roles and functions of the steadiness valves in the system and the adjustments of the general performance of the system aren't fairly clear for iTagPro bluetooth tracker builders of the stability valves, the developed stability valves can solve the problem of hydraulic balance, but carry other problems, as proven in fig. 1 and 2, the steadiness valves are installed on each branch pipe, every important pipe and each fundamental pipe, the balance valves are tremendously difficult, each stability valve is manually adjusted to the designed circulate by using costly special devices, the method is difficult, the adjusted movement is only the designed worth but not the actual value, and the difference of two values at completely different ends can also be totally different, in order that the accuracy of the move adjustment can be totally different; meanwhile, the fixed current and fixed pressure efficiency of the balance valve is changed by consuming 20% -30% of the conveying energy of the water pump, and the issues are opposite to the original functions of hydraulic stability vitality saving and operation quality improvement design, in order that popularization and utility of the balance valve are limited.
Therefore, the standard balance valve has complex structure, iTagPro bluetooth tracker very complex structure for forming a hydraulic steadiness adjusting system, high manufacturing value, difficult guide debugging, low power saving effectivity and the like. The invention aims to supply an intelligent hydraulic balance control system system by a datum level tracking technique, which goals to unravel the issues of high manufacturing cost, difficult guide debugging, ItagPro low power-saving effectivity and the like of a traditional hydraulic balance adjusting system. The variable-frequency water pump set controller, the chilly and hot source controllers and the water terminal controllers are subject management units and are linked with the grasp station controller by a field management bus to kind a DCS laptop community management system; the grasp station controller is used for receiving the corresponding equipment operation information uploaded by each discipline management unit and sending a coordinated operation management instruction of the DCS pc network management system to each discipline management unit, so that the DCS pc network management system, each discipline management unit and all equipment function in line with the rule of 'actual-time load tracking and minimum value'.
