Description

Technical Field

[0001] The present application relates to the field of electromechanical engineering technology in the injection molding industry, and specifically to a process cooling water energy-saving device. Background Art

[0002] In current industrial production, process cooling water systems, as key equipment, play a vital role in maintaining normal operation and extending equipment life. Traditional process cooling water systems often utilize a water pump combined with a variable frequency control cabinet for constant pressure control to achieve energy savings. This control approach monitors the utilization rate of workshop equipment and dynamically adjusts the water pump's output power, thereby ensuring cooling efficiency while reducing energy consumption.

[0003] As attached Figure 1 As shown, a traditional process cooling water energy-saving device includes a water pump 1', a rubber joint 2' disposed at the output end of the water pump 1', a worm gear butterfly valve 3' disposed at the end of the rubber joint 2' away from the water pump 1', a pipe 4' disposed at the end of the worm gear butterfly valve 3' away from the rubber joint 2', a pressure sensor 5' fixedly mounted on the pipe 4', and a frequency conversion control cabinet 6' connected to the water pump 1' and the pressure sensor 5' for controlling the operating frequency of the water pump 1. The water pump is responsible for delivering process cooling water to the water-using end of the workshop equipment; the rubber joint effectively reduces the impact of the water pump's vibration during operation on the pipe; the pipe is responsible for transporting process cooling water; the pressure sensor is responsible for instantly detecting the pressure value in the pipe and transmitting it back to the frequency conversion control cabinet; the frequency conversion control cabinet is responsible for timely adjusting and controlling the operating frequency of the water pump based on the detected pressure value to achieve energy saving.

[0004] However, due to the lack of a necessary booster device at the water pump's output, the system often fails to consistently boost the water pressure at the pump's outlet to the set standard pressure. In practice, when cooling demand for workshop equipment increases, if the water pressure at the pump's outlet fails to meet the set standard pressure, it can lead to poor cooling performance and even affect the normal operation of the equipment. To compensate for this pressure shortfall, some companies have resorted to increasing the number of water pumps or increasing their speed, but this undoubtedly increases the system's energy consumption and operating costs.

[0005] Therefore, the present application provides a process cooling water energy-saving device to solve the above problems. Utility Model Content

[0006] The present application provides a process cooling water energy-saving device, which aims to solve the problem raised in the background art that the output end of the existing water pump lacks the necessary boosting device, and the system is often unable to stably boost the water pressure at the outlet end of the water pump to the set standard pressure value. In actual applications, when the cooling demand of workshop equipment increases, if the water pressure at the outlet end of the water pump cannot meet the set standard pressure value, it may lead to poor cooling effect and even affect the normal operation of the equipment. In order to make up for this pressure shortage, some companies have to take measures such as increasing the number of water pumps or increasing the speed of the water pumps, but this will undoubtedly increase the energy consumption and operating costs of the system.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a process cooling water energy-saving device, comprising a water pump, a rubber flexible joint provided at the output end of the water pump, a worm gear butterfly valve provided at an end of the rubber flexible joint away from the water pump, a pipe provided at an end of the worm gear butterfly valve away from the rubber flexible joint, a pressure sensor fixedly mounted on the pipe, and a frequency conversion control cabinet connected to the water pump and the pressure sensor for controlling the operating frequency of the water pump;

[0008] To facilitate increasing the water pressure at the water pump's output to the standard pressure value, a booster is installed between the water pump and the rubber joint. The booster consists of a straight pipe and a tapered pipe fixedly connected to each end of the straight pipe, with the larger end of the tapered pipe connected to the straight pipe. The addition of the booster ensures that the water pressure at the water pump's outlet can stably reach the set standard pressure value, meeting the cooling water pressure requirements of the workshop equipment. The combined use of a pressure sensor and a frequency conversion control cabinet allows the operating frequency of the water pump to be dynamically adjusted based on the real-time pressure value, avoiding unnecessary energy waste. The rubber joint and worm gear butterfly valve effectively reduce vibration and flow fluctuations during the water pump's operation, improving the stability and reliability of the cooling water system. The booster uses a physical control method to automatically expel air from the water, preventing the air from affecting the outlet water pressure and further enhancing the pressure value after the water is discharged.

[0009] Preferably, to ensure smooth water flow within the supercharger, the connection between the straight tube and the tapered tube is rounded. This rounded edge reduces resistance to water flow within the supercharger, allowing for smoother water flow and improving the supercharger's boosting efficiency. With reduced water flow resistance, the power required by the water pump to provide the same pressure is reduced, thereby reducing energy consumption.

[0010] Preferably, to increase the pressure increase from the supercharger to the water pump output, the straight pipe has a larger diameter than the water pump output. By increasing the straight pipe diameter and utilizing the "nozzle effect," the pressure increase from the supercharger to the water pump output is significantly increased, enabling the cooling water system to output higher-pressure cooling water, meeting the higher cooling water pressure requirements of workshop equipment. Increasing the straight pipe diameter also helps optimize flow distribution, reducing turbulence and eddy currents within the supercharger, lowering energy losses, and improving boosting efficiency.

[0011] Preferably, for convenient connection, flanges are fixedly connected between the water pump, the booster, the rubber joint, the worm gear butterfly valve, and the pipeline. The use of flanges makes the connection between the components more secure and reliable, avoiding water leakage or pressure loss caused by loose connections.

[0012] Preferably, to facilitate installation, the flange is provided with a through-hole, into which a bolt is inserted, and a nut is threadedly mounted on the bolt. The combination of the through-hole, bolt, and nut makes the flange connection process more intuitive and simple, greatly simplifying the installation process. Enhanced connection stability: The tightening action of the bolt and nut ensures a secure and reliable connection between the flanges, preventing water leakage or pressure loss caused by a loose connection.

[0013] Preferably, to improve the sealing performance of the connections, gaskets are provided between the water pump, the booster, the rubber joint, the worm gear butterfly valve, and the pipeline. The combination of flanges and gaskets ensures good sealing performance at the connections between the components, preventing cooling water leakage.

[0014] The addition of a booster ensures that the water pressure at the water pump outlet consistently reaches the set standard pressure, meeting the cooling water pressure requirements of the workshop equipment. The combined use of a pressure sensor and a frequency converter allows the water pump's operating frequency to be dynamically adjusted based on real-time pressure, avoiding unnecessary energy waste. The use of a rubber joint and worm gear butterfly valve effectively reduces vibration and flow fluctuations during operation, improving the stability and reliability of the cooling water system. The booster utilizes a physical control method to automatically expel air from the water, preventing its impact on outlet pressure and further enhancing the outlet pressure.

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] This embodiment provides a process cooling water energy saving device, such as Figure 2-3 As shown, the energy-saving device includes a water pump 1, a rubber flexible joint 2 provided at the output end of the water pump 1, a worm gear butterfly valve 3 provided at the end of the rubber flexible joint 2 away from the water pump 1, a pipe 4 provided at the end of the worm gear butterfly valve 3 away from the rubber flexible joint 2, a pressure sensor 5 fixedly installed on the pipe 4, and a frequency conversion control cabinet 6 connected to the water pump 1 and the pressure sensor 5 for controlling the operating frequency of the water pump 1;

[0022] To increase the water pressure at the output of water pump 1 to the standard pressure, a booster 7 is installed between water pump 1 and rubber joint 2. This booster 7 consists of a straight pipe 701 and a tapered pipe 702 fixedly connected to each end of the straight pipe 701. The larger end of the tapered pipe 702 is connected to the straight pipe 701. The addition of booster 7 ensures that the water pressure at the outlet of water pump 1 consistently reaches the set standard pressure, meeting the cooling water pressure requirements of the workshop equipment. The combined use of a pressure sensor 5 and a frequency converter control cabinet 6 dynamically adjusts the operating frequency of water pump 1 based on real-time pressure, avoiding unnecessary energy consumption. The rubber joint 2 and worm gear butterfly valve 3 effectively reduce vibration and flow rate fluctuations during operation of water pump 1, improving the stability and reliability of the cooling water system. Booster 7 utilizes a physical control mechanism to automatically expel air from the water, preventing its impact on the outlet pressure and further enhancing the outlet pressure. When the process cooling water system is started, water pump 1 begins to operate, extracting cooling water from the water source and pressurizing it to booster 7. Through its unique structural design (a combination of straight pipe 701 and tapered pipe 702), booster 7 further boosts the water pressure at the outlet of water pump 1 to a set standard pressure value. The pressurized cooling water is then stably delivered to pipeline 4 through the regulation of rubber flexible joint 2 and worm gear butterfly valve 3. During the delivery process, pressure sensor 5 monitors the pressure value in pipeline 4 in real time and transmits the data back to frequency conversion control cabinet 6. Frequency conversion control cabinet 6 dynamically adjusts the operating frequency of water pump 1 based on the received pressure value to ensure stable operation and energy saving of the cooling water system.

[0023] Furthermore, to ensure smooth water flow within the supercharger 7, the connection between the straight tube 701 and the tapered tube 702 is rounded. This rounded edge reduces resistance to water flow within the supercharger 7, making the water flow smoother and improving the supercharging efficiency of the supercharger 7. Due to the reduced water flow resistance, the power required by the water pump 1 to provide the same pressure is also reduced, thereby reducing energy consumption. This improved water flow reduces erosion and wear on the internal components of the supercharger 7, extending the service life of the equipment. Inside the supercharger 7, the rounded edge at the connection between the straight tube 701 and the tapered tube 702 allows water to transition more smoothly from the water pump 1 to the tapered tube 702 as it enters the supercharger 7. The rounded edge prevents sharp turns at the connection, reducing water flow resistance and ensuring smoother water flow. Guided by the tapered tube 702, the water flow gradually accelerates and focuses into the straight tube 701, forming a high-pressure water flow.

[0024] Specifically, to increase the pressure boost from supercharger 7 at the output of water pump 1, the diameter of straight pipe 701 is larger than that of the output of water pump 1. By increasing the diameter of straight pipe 701, the "nozzle effect" principle is utilized to significantly increase the pressure boost from supercharger 7 at the output of water pump 1. This allows the cooling water system to deliver cooling water at a higher pressure, meeting the higher cooling water pressure requirements of workshop equipment. Increasing the diameter of straight pipe 701 also helps optimize the flow distribution, reducing turbulence and eddy currents within supercharger 7, minimizing energy loss and improving supercharging efficiency. When water pump 1 is started, cooling water flows from the output of water pump 1. Because the diameter of straight pipe 701 is larger than that of the output of water pump 1, the flow velocity decreases and the pressure increases upon entering supercharger 7. This pressure increase primarily occurs within straight pipe 701, creating a high static pressure. The pressurized cooling water then continues to be regulated by rubber joint 2 and worm gear butterfly valve 3, and is stably delivered to pipeline 4.

[0025] Specifically, to facilitate connection, flanges 8 are fixedly connected between the water pump 1, booster 7, rubber joint 2, worm gear butterfly valve 3, and pipeline 4. The use of flanges 8 ensures a more secure and reliable connection between components, preventing water leakage or pressure loss caused by loose connections. The flexibility of flanges 8 also allows for easy removal and reinstallation of components in the system when they require repair or replacement, eliminating the need for extensive system modifications.

[0026] More specifically, to facilitate installation, flange 8 is provided with a through-hole 801, into which a bolt 9 is inserted, and a nut 901 is threaded onto the bolt 9. The combination of through-hole 801, bolt 9, and nut 901 makes connecting flanges 8 more intuitive and simple, significantly simplifying the installation process. Enhanced connection stability: The tightening action of bolt 9 and nut 901 ensures a secure and reliable connection between flanges 8, preventing water leakage or pressure loss caused by a loose connection. The through-hole 801 in flange 8 plays a key role in the connection details. First, align the flanges 8 of the components to be connected, ensuring that the through-holes 801 correspond one-to-one. Then, insert the shank of bolt 9 through the corresponding through-hole 801 in the two flanges 8. Next, fit nut 901 over the outer threads of bolt 9 and tighten it using a tool (such as a wrench). As nut 901 is tightened, the gap between the two flanges 8 gradually decreases until they fit snugly.

[0027] Specifically, in order to improve the sealing performance of the connection: a sealing gasket 10 is provided between the adjacent water pump 1, the supercharger 7, the rubber flexible joint 2, the worm gear butterfly valve 3 and the pipe 4. The use of the flange 8 and the sealing gasket 10 can ensure that the connection between the components has good sealing performance and prevent cooling water leakage. The addition of the sealing gasket 10 reduces the wear of the connection caused by long-term water erosion, thereby extending the service life of the equipment. In terms of connection details, in addition to the flange 8, bolts 9 and nuts 901 mentioned above, sealing gaskets 10 are also added to the connection between the components. The sealing gasket 10 is placed between the flanges 8 of two adjacent components. When the bolts 9 and nuts 901 are tightened, the sealing gasket 10 is squeezed and deformed, filling the tiny gap between the flanges 8, thereby achieving a good sealing effect.

[0028] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
