The Variable-frequency Water Pump Set Controller
Legal standing (The authorized status is an assumption and is not a legal conclusion. Current Assignee (The listed assignees could also be inaccurate. Priority date (The precedence date is an assumption and isn't a legal conclusion. The invention discloses an clever hydraulic steadiness control system system primarily based on a datum point monitoring technique. The control gadget includes: the system contains a foremost station controller, a variable-frequency water pump set controller, a chilly and heat source controller and water terminal controllers. Each controller is linked with every 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 essentially the most unfavorable finish, particularly the entire load change of the system in real time on the minimum price; while different controllers management the respective gadgets to track the respective end load modifications in actual time at minimal cost; underneath the coordinated control of the grasp station controller, all of the gadgets of the water circulation system function based on the rule of 'actual-time load tracking and minimal price', particularly the clever function of self-adaption and minimum power consumption.
Thus, iTagPro technology the system is in an integrally optimized dynamic hydraulic stability state intelligently on a regular basis, and the best goal of supplying water on demand at the minimal value is achieved by every water use finish. The invention pertains to the sector of hydraulic stability control of a water circulation system. The water circulation system is extensively applied in the manufacturing and life of staff and folks, but the issue of hydraulic imbalance affecting the security, the operation efficiency and iTagPro geofencing the quality of the water circulation system is all the time plagued in the trade; the hydraulic imbalance is the phenomenon that each finish of the system doesn't have the function of supplying water in accordance with the need, in order that the cold and scorching of each finish of the system are uneven, the security is reduced, the vitality consumption is elevated, and the operation quality is decreased; because the standard reduction idea, iTagPro smart tracker linear considering, stacking and stacking integrated scientific paradigm and the nonlinear complex water circulation system are usually not matched in nature, the formed water circulation system just isn't caused by an inherent wholesome construction.
The normal methodology for fixing the hydraulic imbalance is to install a stability valve on a foremost pipe and a department pipe of a water circulation system. There are two sorts of balancing valves: constant circulation kind balance valve and fixed pressure kind steadiness valve. While the interior structure and the intrinsic operation rule of the water circulation system and the roles and capabilities of the balance valves in the system and the changes of the overall efficiency of the system should not quite clear for builders of the steadiness valves, the developed steadiness valves can resolve the problem of hydraulic steadiness, however deliver different issues, as shown in fig. 1 and 2, the stability valves are put in on every department pipe, each most important pipe and every essential pipe, iTagPro smart device the balance valves are drastically difficult, every balance valve is manually adjusted to the designed move by utilizing expensive particular instruments, wireless tag finder the method is difficult, the adjusted movement is just the designed value however not the actual worth, and the difference of two values at different ends can also be totally different, so that the accuracy of the flow adjustment can also be different; in the meantime, the fixed current and constant pressure performance of the balance valve is changed by consuming 20% -30% of the conveying power of the water pump, and the problems are contrary to the unique functions of hydraulic balance energy saving and operation quality improvement design, in order that popularization and application of the steadiness valve are limited.
Therefore, the traditional steadiness valve has complex structure, very advanced structure for forming a hydraulic stability adjusting system, high manufacturing value, troublesome manual debugging, low energy saving efficiency and the like. The invention goals to provide an clever hydraulic stability control system device by a datum level monitoring methodology, which aims to unravel the issues of excessive manufacturing value, difficult manual debugging, low vitality-saving effectivity and the like of a standard hydraulic stability adjusting system. The variable-frequency water pump set controller, iTagPro technology the chilly and sizzling source controllers and the water terminal controllers are field control units and are related with the grasp station controller by means of a field control bus to type a DCS computer network control system; the grasp station controller is used for receiving the corresponding equipment operation information uploaded by every area control unit and sending a coordinated operation management instruction of the DCS pc network management system to each subject control unit, so that the DCS pc community control system, every field control unit and iTagPro technology all tools function based on the rule of 'real-time load monitoring and minimal value'.
