Description

[Technical Field]

[0001] The present application relates to pressure balance systems, and more particularly to liquid circulation pressure balance systems. [Background technology]

[0002] In mechanical systems, different components (such as robot arms and conveyors) are typically driven by motors to automatically transport or move objects. Because motors generate heat during operation, motors operating for long periods of time in high-temperature environments tend to operate with insufficient heat dissipation, resulting in reduced efficiency. To effectively reduce the motor's temperature, a liquid-cooled motor is proposed. A liquid-cooled motor operates in combination with a circulation system, where the water-cooled liquid in the circulation system dissipates heat from the motor body, thereby reducing the motor's temperature.

[0003] However, in conventional technology, damage to the circulation system could only be detected when the temperature of the liquid-cooled motor was abnormal or the circulation system stopped. As a result, relevant parties were unable to grasp the status of the circulation system in real time and perform maintenance immediately, which caused inconvenience in maintenance.

[0004] Therefore, one of the issues to be resolved in this field is how to propose a circulation system that can grasp the operating status in real time. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to solve the above technical problems, the present application proposes a liquid circulation pressure balancing system, which distributes the output through multiple pumps to extend the service life of the pumps, and detects changes in pipe pressure values ​​at any time, thereby understanding the status of the liquid circulation pressure balancing system in real time and allowing relevant parties to respond immediately when an abnormality occurs, thereby achieving the purpose of improving maintenance convenience. [Means for solving the problem]

[0006] To achieve the above object, this application proposes a liquid circulation pressure balance system including a liquid-cooled motor, a system pump, a balance pump, a pressure sensor, and a control module. The liquid-cooled motor is connected to a pipe through which a water-cooled liquid flows to regulate the temperature of the liquid-cooled motor. The system pump is connected to the liquid-cooled motor via the pipe and delivers the water-cooled liquid to the liquid-cooled motor at a first output pressure. The balance pump is connected to the system pump via the pipe and is used to adjust a second output pressure based on a balance pump control signal and deliver the water-cooled liquid to the system pump at the second output pressure. The pressure sensor is used to detect a pipe pressure value in the pipe. The control module is electrically connected to the pressure sensor and the balance pump and is used to receive the pipe pressure value. During installation, the control module updates the balance pump control signal based on the pipe pressure value and sends the balance pump control signal to the balance pump.

[0007] As described above, the liquid circulation pressure balancing system of the present application distributes the output through multiple pumps, thereby extending the service life of each pump, and by detecting changes in pipe pressure at any time, the status of the liquid circulation pressure balancing system can be grasped in real time, allowing relevant parties to respond immediately when an abnormality occurs, thereby achieving the purpose of improving the convenience of maintenance.

[0009] Please refer to Figures 1 and 2. Figure 1 is a diagram showing an embodiment of a liquid circulation pressure balance system according to an embodiment of the present application. Figure 2 is a diagram showing an embodiment of a control module according to an embodiment of the present application. The liquid circulation pressure balance system 1 includes a system pump 10, a liquid-cooled motor 11, a pressure sensor 12, a balance pump 13, and a control module 14. The system pump 10, the liquid-cooled motor 11, the pressure sensor 12, and the balance pump 13 are connected via a pipe 15. The pipe 15 is, for example, a metal pipe or a plastic pipe. A water-cooled liquid flows through the pipe 15.

[0010] The system pump 10 is connected to the liquid-cooled motor 11 via a pipe 15. The system pump 10 delivers water-cooling liquid to the liquid-cooled motor 11 at a first output pressure. The liquid-cooled motor 11 is connected to the pipe 15. The water-cooling liquid flows through the liquid-cooled motor 11 via the pipe 15. Heat from the liquid-cooled motor 11 is dissipated by the flowing water-cooling liquid, thereby regulating the temperature of the liquid-cooled motor 11 and preventing the liquid-cooled motor 11 from operating in a high-temperature environment. A pressure sensor 12 is provided on the pipe 15 and is located between the liquid-cooled motor 11 and the balance pump 13. The pressure sensor 12 detects the pipe pressure value of the pipe 15 and transmits the pipe pressure value to the control module 14. The balance pump 13 is connected to the system pump 10 via the pipe 15. The balance pump 13 receives a balance pump control signal from the control module 14, adjusts the output second output pressure based on the balance pump control signal, and delivers water-cooling liquid to the system pump 10 at the second output pressure. The balance pump control signal is, for example, a voltage control signal or a current control signal. In one embodiment, the number of balance pumps 13 may be plural, and the present application is not limited thereto.

[0011] Therefore, the liquid circulation pressure balance system 1 of the present application has at least the system pump 10 and the balance pump 13 jointly outputting, that is, the output of the system pump 10 is reduced through the balance pump 13, and the output of the pump in the liquid circulation pressure balance system 1 is reduced, thereby extending the service life of the system pump 10 and the liquid circulation pressure balance system 1.

[0012] The control module 14 includes a network communication interface 141, an input / output interface 142, and a control unit 143. The control unit 143 is electrically connected to the network communication interface 141 and the input / output interface 142. The network communication interface 141 is, for example, a communication interface conforming to a wired network communication standard or a wireless communication standard. The network communication interface 141 is, for example, a communication interface conforming to the Internet Communication Protocol (TCP / IP) specification. The input / output interface 142 is, for example, a contact interface conforming to the NO (Normal Open) / NC (Normal Close) dry contact standard. The control unit 143 is, for example, a microcontroller. The control module 14 is communicatively connected to the pressure sensor 12 and the balance pump 13 via the input / output interface 142. The control unit 143 is used to receive the pipe pressure value via the input / output interface 142 and output a balance pump control signal. An ideal pressure value for the pipe 15 is pre-stored in the control unit 143. The ideal pressure value may be a fixed value or a range of values. For example, the ideal pressure value may be, for example, -30 kPa (kilopascals), or may be, for example, -30 kPa to -25 kPa. During the installation stage of the liquid circulation pressure balance system 1, the control unit 143 receives the pipe pressure value detected by the pressure sensor 12 and determines whether to update the balance pump control signal based on the received pipe pressure value. For example, the control unit 143 compares the pipe pressure value with the ideal pressure value and determines whether the pipe pressure value is the same as the ideal pressure value or whether the pipe pressure value is within the range of the ideal pressure value. If the determination result is "Yes," this means that the current pipe pressure value is the desired pipe pressure value, the second output pressure output by the balance pump 13 is the desired output pressure, and the liquid circulation pressure balance system 1 has completed adjusting the pipe pressure value. If the determination result is "No," this means that the current pipe pressure value is not the desired pipe pressure value.The control unit 143 further updates the balance pump control signal and sends the updated balance pump control signal to the balance pump 13. The balance pump 13 increases or decreases the output second pressure based on the received balance pump control signal, that is, the balance pump 13 increases or decreases the pressure of the water-cooling liquid based on the received balance pump control signal, thereby adjusting the pipe pressure value to a desired pipe pressure value.

[0013] 3 , the control module 14 is electrically connected to the system pump 10 via an input / output interface 142. The control unit 143 of the control module 14 is used to generate and send a system pump control signal to the system pump 10. The system pump control signal is, for example, a voltage control signal or a current control signal. During the installation stage of the liquid circulation pressure balance system 1, a related person (e.g., an installer) can set the system pump control signal via the control unit 143 so that the system pump 10 delivers water-cooling liquid to the liquid-cooled motor 11 at a desired first output pressure based on the system pump control signal. The first output pressure is, for example, 20 kPa.

[0014] After the installation phase of the liquid circulation pressure balance system 1 is completed, the liquid circulation pressure balance system 1 begins to operate in the operation phase. In the operation phase, the system pump 10 continuously delivers water cooling liquid to the liquid-cooled motor 11 at a first output pressure based on the system pump control signal determined in the installation phase, and the balance pump 13 continuously delivers water cooling liquid to the system pump 10 at a second output pressure based on the balance pump control signal determined in the installation phase. In the operation phase, the pressure sensor 12 continuously detects the pipe pressure value of the pipe 15 and transmits the pipe pressure value to the control module 14.

[0015] During operation, the control unit 143 of the control module 14 receives the pipe pressure value detected by the pressure sensor 12 and determines whether to update the balance pump control signal based on the received pipe pressure value. For example, the control unit 143 compares the pipe pressure value with an ideal pressure value to determine whether the pipe pressure value is the same as the ideal pressure value or whether the pipe pressure value is within the range of the ideal pressure value. If the result of the determination is "yes," this means that the current pipe pressure value is the desired pipe pressure value, the second output pressure output by the balance pump 13 is the desired output pressure, and the liquid circulation pressure balance system 1 maintains a normal operating state. If the result of the determination is "no," this means that the current pipe pressure value is not the desired pipe pressure value, i.e., an abnormality (e.g., a pipe break or an abnormal output of the system pump 10) occurs in the pipe 15 of the liquid circulation pressure balance system 1, causing a change in the pipe pressure value. The control unit 143 then updates the balance pump control signal based on the pipe pressure value and sends the updated balance pump control signal to the balance pump 13. The balance pump 13 increases or decreases the second output pressure output based on the received balance pump control signal, that is, the balance pump 13 increases or decreases the pressure of the water cooling liquid based on the received balance pump control signal, thereby adjusting the pipe pressure value to the desired pipe pressure value and avoiding further damage to the system pump 10, liquid cooling motor 11, pressure sensor 12 and balance pump 13 in the liquid circulation pressure balance system 1 due to changes in the pipe pressure value.

[0016] Furthermore, the control module 14 is communicatively connected to an external device via the network communication interface 141 and / or the input / output interface 142. The external device may be, for example, a remote control system or a mechanical system. For example, the control module 14 may be communicatively connected to a remote control system via the network communication interface 141, or to a mechanical system of the liquid-cooled motor 11 via the input / output interface 142. Therefore, the control unit 143 of the control module 14 may generate an alarm signal to be sent to an external device based on the pipe pressure value. For example, during operation, the control unit 143 compares the pipe pressure value with an ideal pressure value and determines that the pipe pressure value is not the same as the ideal pressure value or is not within the range of the ideal pressure value. This indicates that the current pipe pressure value is not the desired pipe pressure value, i.e., an abnormality has occurred in the pipe 15 of the liquid circulation pressure balance system 1, causing the pipe pressure value to change. Therefore, the control unit 143 can generate an alarm signal based on the current pipe pressure value and transmit the alarm signal to an external device via the network communication interface 141 and / or the input / output interface 142. This allows personnel in a remote location or near the machine to know that an abnormality has occurred in the liquid circulation pressure balance system 1 through the alarm signal, grasp the status of the liquid circulation pressure balance system 1 in real time, and perform corresponding maintenance in real time. In one embodiment, the alarm signal may include address information of the control module 14. Therefore, in an embodiment where multiple liquid circulation pressure balance systems 1 exist, personnel can quickly identify the abnormal liquid circulation pressure balance system 1 using the address information. In one embodiment, the alarm signal may further include identification information of the balance pump 13 and / or the system pump 10, allowing personnel to quickly identify the abnormal balance pump 13 and / or the system pump 10 using the identification information.

[0017] Referring to Fig. 4, Fig. 4 is a diagram showing an embodiment of a pressure balancing method at the installation stage according to an embodiment of the present application, which can be realized in the above-mentioned liquid circulation pressure balancing system 1. Fig. 4 includes steps S110, S120, S130, and S140.

[0018] In step S110, a pipe pressure value is acquired. In this step, the pressure sensor 12 detects the pipe pressure value of the pipe 15 and transmits the pipe pressure value to the control module 14, which acquires the pipe pressure value. In step S120, it is determined whether the pipe pressure value is an ideal pressure value. In this step, the control module 14 compares the pipe pressure value with the ideal pressure value to determine whether the pipe pressure value is the same as the ideal pressure value or whether the pipe pressure value is within the range of the ideal pressure value. If the determination result is "yes," step S130 is executed, or conversely, step S140 is executed. In step S130, the balance pump 13 maintains the second output pressure output based on the balance pump control signal. In this step, the control module 14 determines that the pipe pressure value is the same as the ideal pressure value or is within the range of the ideal pressure value, which means that the current pipe pressure value is the desired pipe pressure value, the second output pressure output by the balance pump 13 is the desired output pressure, and the adjustment of the liquid circulation pressure balance system 1 has been completed. In step S140, the control module 14 updates the balance pump control signal based on the pipe pressure value, causing the balance pump 13 to adjust the second output pressure based on the balance pump control signal. In this step, the control module 14 determines that the pipe pressure value is different from the ideal pressure value or is not within the range of the ideal pressure value, meaning that the current pipe pressure value is not the desired pipe pressure value. Therefore, the control module 14 further updates the balance pump control signal and sends the updated balance pump control signal to the balance pump 13, causing the balance pump 13 to adjust the pipe pressure value by increasing or decreasing the output second output pressure based on the received balance pump control signal. After completing step S140, the process returns to step S110.

[0019] Referring to Fig. 5, Fig. 5 is a diagram showing an embodiment of a pressure balancing method in an operating stage according to an embodiment of the present application, which can be realized in the above-mentioned liquid circulation pressure balancing system 1. Fig. 5 includes steps S210, S220, S230, and S240.

[0020] In step S210, a pipe pressure value is acquired. In this step, the pressure sensor 12 detects the pipe pressure value of the pipe 15 and transmits the pipe pressure value to the control module 14, which acquires the pipe pressure value. In step S220, it is determined whether the pipe pressure value is an ideal pressure value. In this step, the control module 14 compares the pipe pressure value with the ideal pressure value to determine whether the pipe pressure value is the same as the ideal pressure value or whether the pipe pressure value is within the range of the ideal pressure value. If the determination result is "yes," step S230 is executed, or conversely, step S240 is executed. In step S230, the balance pump 13 maintains the second output pressure output based on the balance pump control signal. In this step, the control module 14 determines that the pipe pressure value is the same as the ideal pressure value or is within the range of the ideal pressure value, which means that the current pipe pressure value is the desired pipe pressure value and that the second output pressure output by the balance pump 13 is the desired output pressure. After completing step S230, the process returns to step S210, where the control module 14 continuously obtains the pipe pressure value from the pressure sensor 12. In step S240, the control module 14 updates the balance pump control signal based on the pipe pressure value, and the balance pump 13 adjusts the second output pressure based on the balance pump control signal. In this step, the control module 14 determines that the pipe pressure value is different from the ideal pressure value or is not within the range of the ideal pressure value, meaning that the current pipe pressure value is not the desired pipe pressure value. Therefore, the control module 14 further updates the balance pump control signal and sends the updated balance pump control signal to the balance pump 13, so that the balance pump 13 adjusts the pipe pressure value by increasing or decreasing the second output pressure output based on the received balance pump control signal. After completing step S240, the process returns to step S210.

[0021] Referring to FIG. 6, FIG. 6 illustrates another embodiment of a pressure balancing method during operation according to an embodiment of the present application. The pressure balancing method can be implemented in the liquid circulation pressure balance system 1. The difference between FIG. 6 and FIG. 5 is that after determining "No" in step S220, step S250 is executed. In step S250, an alarm signal is generated and transmitted to an external device. In this step, the control module 14 determines that the pipe pressure value is different from the ideal pressure value or is not within the range of the ideal pressure value, which means that the current pipe pressure value is not the desired pipe pressure value. Therefore, the control module 14 further generates a corresponding alarm signal based on the current pipe pressure value and transmits the alarm signal to an external device. This allows relevant personnel at a remote location or near the machine to know that an abnormality has occurred in the liquid circulation pressure balance system 1 through the alarm signal, grasp the status of the liquid circulation pressure balance system 1 in real time, and perform corresponding maintenance in real time.

[0022] In summary, the liquid circulation pressure balancing system of the present application distributes power output through multiple pumps, thereby extending the service life of each pump, and by detecting changes in pipe pressure at any time, the status of the liquid circulation pressure balancing system can be grasped in real time, allowing relevant parties to respond immediately when an abnormality occurs, thereby achieving the purpose of improving maintenance convenience.
