Description

Technical Field

[0001] This invention relates to frequency conversion control technology for pump units, and more specifically, to a digital intelligent operation energy efficiency, health and self-healing two-way dual-link control system for pump units and valve pipeline systems, and a method for controlling their operating characteristics. Background Technology

[0002] Combination Figure 1 As shown, in current pump unit frequency converter control systems, the adjustment range is typically set manually, and then the frequency converter controls and adjusts the motor speed to change the pump unit's operating speed. Additionally, various pressure, temperature, and vibration sensors are installed on the pump unit to monitor its operation. However, this data acquisition and early warning system only simply reflects the pump unit's operating status and improves upon historical data. This approach cannot effectively help solve real-time operational problems or improve the pump unit's operating status, especially in dynamically preventing the escalation and deterioration of existing problems.

[0003] Furthermore, valve adjustments via actuators are merely used to alter the pipeline system resistance to meet its resistance characteristics. This traditional, non-interactive control method, where pump units and valves are separate, fails to integrate the pipeline system resistance characteristics regulated by valves with the pump unit's speed adjustment and operational efficiency and reliability indicators in real time. Consequently, the operational efficiency and reliability of the pump unit and pipeline valve system are relatively low. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a digital and intelligent operation energy efficiency, health and self-healing bidirectional dual-linkage control system for pump units and valve pipeline systems, and its operation characteristic control method. By utilizing the frequency converter unit of the pump unit and the control unit of the valve actuator for interactive control and adjustment, the pump unit and valve system can achieve bidirectional linkage operation with energy efficiency, health and self-healing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The first aspect of this invention provides a digital intelligent operation, energy efficiency, health, and self-healing bidirectional dual-linkage control system for pump units and valve pipeline systems, comprising:

[0007] Pump unit sensors are used to collect the operating energy efficiency and health parameters of the pump unit;

[0008] Motor sensors are used to collect parameters related to the energy efficiency and health of motors.

[0009] Valve actuator sensors are used to collect operating energy efficiency and health parameters of valve actuators;

[0010] Valve sensors are used to collect valve operating energy efficiency and health parameters;

[0011] The pump unit-valve real-time bidirectional dual-link controller is used to acquire data from the pump unit sensors, the motor sensors, the valve actuator sensors, and the valve sensors. When the data changes, it performs data processing and analysis with the goal of optimizing the pump's operating energy efficiency and safety reliability.

[0012] Preferably, the input terminal of the real-time bidirectional dual-connection controller for pump unit-valve operation is connected to the pump unit sensor, the motor sensor, the valve actuator sensor, and the valve sensor signal, and the output terminal of the real-time bidirectional dual-connection controller for pump unit-valve operation is connected to the pump unit frequency converter controller and the valve actuator signal.

[0013] Preferably, the frequency converter of the pump unit is connected to the motor signal.

[0014] The second aspect of the present invention provides a method for regulating the operating characteristics of a digital intelligent operation energy efficiency, health and self-healing bidirectional dual-linkage regulation system for pump units and valve pipeline systems provided in the first aspect of the present invention;

[0015] The data collected by the pump unit sensor, the motor sensor, the valve actuator sensor, and / or the valve sensor is transmitted to the real-time dual-controller for pump unit-valve operation. When the collected data changes, the real-time dual-controller for pump unit-valve operation processes and analyzes the data with the goal of optimizing the pump's operating energy efficiency and safety reliability. If the changed value does not meet the pump's energy efficiency and safety reliability requirements, the real-time dual-controller for pump unit-valve operation sends instructions to the valve actuator and / or the pump unit frequency converter to make corresponding adjustments to the motor and / or the valve.

[0016] Preferably, the method for regulating operating characteristics specifically includes:

[0017] The pump unit sensors collect the pump's operating energy efficiency and health parameters, and the motor sensors collect the motor's operating energy efficiency and health parameters. Both are transmitted to the real-time bidirectional dual-controller for pump unit-valve operation. The system analyzes and compares the energy efficiency and health status of the pump unit composed of the pump and the motor, and provides the pump unit's operating energy efficiency index and health reliability. When the pump unit deviates from the optimal point for energy efficiency and health reliability, the real-time bidirectional dual-controller for pump unit-valve operation sends a command to the pump unit's frequency converter to adjust the motor's speed.

[0018] Preferably, the pump's operating efficiency and health parameters include flow rate, pressure, temperature, torque, and vibration; and / or

[0019] The operating energy efficiency and health parameters of the motor include voltage, current, temperature, and vibration.

[0020] Preferably, the method for regulating the operating characteristics of the intelligent operation energy efficiency and health self-healing bidirectional dual-link system specifically includes:

[0021] The valve actuator sensor collects the operating energy efficiency and health parameters of the valve actuator, and the valve sensor collects the operating energy efficiency and health parameters of the valve. Both are transmitted to the pump unit-valve real-time dual controller to analyze and compare the energy efficiency and health status of the valve actuator and the valve, and to provide the operating energy efficiency index and health reliability of the valve actuator and the valve. When the valve deviates from the optimal point of energy efficiency index and optimal point of health reliability, the pump unit-valve real-time bidirectional dual controller sends a command to the valve actuator to adjust the opening degree of the valve.

[0022] Preferably, the operating energy efficiency and health parameters of the valve actuator include voltage, current, valve opening degree, and vibration; and / or

[0023] The valve's operational efficiency and health parameters include pressure, temperature, displacement, flow rate, and vibration.

[0024] This invention provides a digital intelligent operation energy efficiency, health, and self-healing bidirectional dual-linkage control system for pump units and valve pipeline systems, along with its operation characteristic adjustment method. By utilizing the pump unit's frequency converter and valve actuators for interactive control and adjustment, the system enables the pump unit and valves in the pipeline system to operate in a coordinated manner, achieving energy efficiency, health, and self-healing linkage. This is the first time that pump unit operating energy efficiency indicators and operational health and reliability have been simultaneously controlled as operational optimization parameters and objectives. It is also the first time that bidirectional joint control of the pump unit and valves in the pipeline system has been implemented, achieving dual-objective optimization of energy efficiency and reliability. Interactive and complementary adjustments are achieved through a real-time bidirectional joint controller for pump unit-valve operation. The pump unit's operating energy efficiency indicators and health and reliability are simultaneously optimized in a self-healing manner. Data collected by sensors in the pump unit and valves is interconnected with the pump unit's frequency converter and the valves via communication elements to the shared real-time bidirectional joint controller. When the pump unit inputs dynamic signals to the real-time bidirectional joint controller, and the operating energy efficiency indicators change, the controller performs calculations and comparisons based on the objective function of optimized operation. Based on the optimization requirements of the pump unit's operating energy efficiency and safety reliability indicators, corresponding adjustments are made to the pump unit's speed and valve opening until the signals output by the pump unit's sensors achieve energy efficiency optimization and meet the requirements for operational safety and reliability. This invention transforms traditional discrete control equipment into an intelligent agent network with autonomous decision-making capabilities. Its digital twin interface can also connect to factory equipment energy and reliability management systems, providing an ideal fluid equipment control solution for Industry 4.0 scenarios. Furthermore, AI algorithms can be added to achieve proactive control under unsteady conditions. Attached Figure Description

Detailed Implementation

[0029] To better understand the above-mentioned technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Combination Figure 2 As shown, this invention provides a digital intelligent operation, energy efficiency, health, and self-healing bidirectional dual-linkage control system for pump units and valve pipeline systems, comprising:

[0031] Pump unit sensor 1 is used to collect the operating energy efficiency and health parameters of pump unit 2;

[0032] Motor sensor 3 is used to collect the operating energy efficiency and health parameters of motor 4;

[0033] Valve actuator sensor 5 is used to collect the operating energy efficiency and health parameters of valve actuator 6;

[0034] Valve sensor 7 is used to collect the operating energy efficiency and health parameters of valve 8;

[0035] The real-time bidirectional dual-connection controller 9 for pump unit-valve operation is used to acquire data from pump unit sensor 1, motor sensor 3, valve actuator sensor 5, and valve sensor 7. When the data changes, the controller performs data processing and analysis with the goal of optimizing the operating energy efficiency and safety and reliability of the pump unit composed of pump 2 and motor 4.

[0036] The input terminal of the real-time bidirectional dual-connection controller 9 for pump unit-valve operation is connected to the pump unit sensor 1, motor sensor 3, valve actuator sensor 5, and valve sensor 7. The output terminal of the real-time bidirectional dual-connection controller 9 for pump unit-valve operation is connected to the pump unit frequency converter controller 10 and valve actuator 6.

[0037] The pump unit frequency converter 10 is connected to the motor 4 via signal.

[0038] In this invention, various sensors of the pump unit and pipeline system 100 are connected to the input terminal of the real-time bidirectional dual-controller 9 for pump unit-valve operation. When the output signals of various sensors change, the real-time bidirectional dual-controller 9 for pump unit-valve operation performs data processing and analysis with the goal of optimizing the energy efficiency and safety reliability of the pump unit. If the changed value does not meet the energy efficiency and safety reliability requirements of the pump unit, the real-time bidirectional dual-controller 9 for pump unit-valve operation adjusts the valve 8 accordingly, such as changing the opening degree of valve 8. This alters the pipeline characteristics of the entire operating system.

[0039] See again Figure 2 As shown, the present invention also provides a method for regulating the operating characteristics of energy efficiency, health and self-healing using the intelligent operation energy efficiency, health and self-healing bidirectional dual-linkage regulation system of the present invention.

[0040] Pump unit sensor 1, motor sensor 3, valve actuator sensor 5 and / or valve sensor 6 collect data from the corresponding pump 2, motor 4, valve actuator 6 and / or valve 8 and transmit it to the pump unit-valve real-time dual controller 9. When the collected data changes, the pump unit-valve real-time dual controller 9 processes and analyzes the data with the goal of optimizing the energy efficiency and safety reliability of the pump unit (pump 2 + motor 4). If the changed value cannot meet the energy efficiency and safety reliability of the pump unit, the pump unit-valve real-time dual controller 9 sends a command to the valve actuator 6 and / or pump unit frequency converter 10 to adjust the speed of motor 4 and / or the opening of valve 8 accordingly.

[0041] The present invention's intelligent operation, energy efficiency, health, self-healing, two-way dual-linkage regulation method specifically includes:

[0042] Pump unit sensor 1 collects the operating energy efficiency and health parameters of pump 2 (such as flow rate, pressure, temperature, torque, and vibration), and motor sensor 3 collects the operating energy efficiency and health parameters of motor 4 (such as voltage, current, temperature, and vibration). Both are transmitted to the pump unit-valve real-time bidirectional dual-connection controller 9 to analyze and compare the energy efficiency and health status of the pump unit composed of pump 2 and motor 4, and provide the operating energy efficiency index and health reliability of the pump unit. When the pump unit deviates from the optimal point of energy efficiency index and optimal point of health reliability, the pump unit-valve real-time bidirectional dual-connection controller 9 sends a command to the pump unit frequency converter controller 10 according to the set standard technical requirements to make certain energy efficiency improvement and health reliability improvement related adjustments, such as adjusting the speed of motor 4.

[0043] The greatest advantage of this invention is that by controlling the operating speed of the pump 2 via the motor 4, the system achieves optimal energy efficiency while maintaining safe and reliable operation. In other words, the energy efficiency and safety / reliability of the pump unit and piping system are dynamically optimized.

[0044] The present invention's intelligent operation, energy efficiency, health, self-healing, two-way dual-linkage regulation method specifically includes:

[0045] The valve actuator sensor 5 collects the operating energy efficiency and health parameters (such as voltage, current, valve opening degree, and vibration) of the valve actuator 6, and the valve sensor 7 collects the operating energy efficiency and health parameters (such as pressure, temperature, displacement, flow rate, and vibration) of the valve 8. Both are transmitted to the pump unit-valve real-time bidirectional dual controller 9 to analyze and compare the energy efficiency and health status of the valve actuator 6 and the valve 8, and provide the operating energy efficiency index and health reliability of the valve actuator 6 and the valve 8. When the valve 8 deviates from the optimal point of energy efficiency index and optimal point of health reliability, self-healing adjustment is performed to improve the operating energy efficiency index and improve the operating health reliability. For example, the pump unit-valve real-time dual controller 9 sends a command to the valve actuator 6 to adjust the opening degree of the valve 8.

[0046] The greatest advantage of this invention is that, through the control and adjustment of the valve actuator 6, the system's energy efficiency index is optimized under the condition of ensuring safe and reliable operation. The energy efficiency index and safety and reliability of the pump unit and pipeline system are dynamically optimized to meet the user's operating conditions and achieve the pump unit's energy efficiency self-healing goal.

[0047] In this invention, the real-time dual-controller 9 for pump unit-valve operation, combined with the valve actuator 6 and the pump unit frequency converter 10, enables simultaneous, self-healing, and coordinated control and regulation of the pump unit and valve 8. This integrates the features of the two control units mentioned earlier, which operate independently, fully meeting the operational requirements for improved energy efficiency and safety / reliability of the pump unit system. This ensures that the operation of the pipeline system 100 and the pump unit is based on optimized energy efficiency and safety / reliability. In other words, regardless of whether the pump unit operates under constant pressure output (constant head) or constant flow output (constant flow rate), its energy efficiency and safety / reliability remain in an optimized, self-healing state. The internal linkage regulation of valve 8 within the pump unit and pipeline system 100 exhibits self-learning and self-improvement. The greatest advantage of this invention is that through the interactive self-healing regulation of the pump unit controller and valve actuator, optimal system energy efficiency is achieved while ensuring operational safety and reliability. That is, the operational energy efficiency and safety / reliability of the pump unit and pipeline system 100 achieve a dynamically optimized combination.

[0048] In actual pump unit operation, if the user's production operation requires that the output pressure of pump 2 remain constant, interactive self-healing adjustment can be achieved through the pump unit frequency converter 10 and the pump unit-valve real-time bidirectional dual-connection controller 9. This allows the valve actuator 6 to adjust the operating opening of valve 8, thereby changing the characteristics of the pipeline system. Simultaneously, the pump unit frequency converter 10 also needs to adjust the pump unit's operating speed to maintain a constant output pressure for pump 2. Whether the valve 8 opening is increased or decreased, and whether the pump unit's speed is increased or decreased, depends on the degree of optimization in improving the pump unit system's energy efficiency indicators and safety and reliability. Figure 3 As shown.

[0049] Furthermore, in actual pump unit operation, if the production operation requires a constant pump unit output flow, the pump unit and pipeline system operation can be dynamically adjusted in real time using the pump unit-valve real-time bidirectional dual-link controller 9. This requires the valve actuator 6 to adjust the operating opening of the pump unit's valve 8 to change the pipeline system characteristics. Simultaneously, the pump unit's frequency converter 10 needs to adjust the pump unit's operating speed to maintain a constant output flow of pump 2. The increase or decrease in the valve 8 opening and the increase or decrease in the pump unit speed depend on the degree of optimization in improving the pump unit system's energy efficiency indicators and safety and reliability. Figure 4 As shown.
