Description

Technical Field

[0001] This utility model relates to the field of constant pressure water supply technology, specifically to an intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel. Background Technology

[0002] This equipment regulates the water pump speed via a frequency converter, combines this with real-time feedback of pipeline pressure from a pressure sensor, and dynamically adjusts the pump's operating status using a PID control algorithm to achieve constant pressure water supply. When multiple pumps are connected in parallel, the system automatically increases or decreases the number of frequency pumps based on water consumption to ensure that the total flow matches the demand, while avoiding the impact of frequent start-stop cycles on the equipment.

[0003] Existing intelligent variable frequency constant pressure water supply equipment based on multiple pumps in parallel is not convenient for separating the detection and control components from the pump body to avoid mutual interference, and cannot simultaneously reduce the temperature of multiple sets of intelligent variable frequency pumps to achieve a rapid cooling effect. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel. The intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel facilitates the separation of detection and control elements from the pump body, avoiding mutual interference, and simultaneously reduces the temperature of multiple sets of intelligent variable frequency pump bodies, achieving a rapid cooling effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is an intelligent variable frequency constant pressure water supply equipment based on multiple pumps in parallel, including a water supply chamber and a cover plate. The top of the water supply chamber is fitted with a cover plate, and a cooling chamber is connected to the top of the cover plate. A thermostat is installed on the top of the cooling chamber by screws. A cold air fan is installed on the top of the cover plate and at one end of the cooling chamber by a mounting base. A partition is welded inside the water supply chamber. The water supply chamber is equipped with an intelligent variable frequency pump body installed at equal intervals on one side of the partition via mounting base. Rubber tube sleeves are fitted at equal intervals on the partition via mounting holes. The outlet of the intelligent variable frequency pump body is connected to an output pipe, and the output pipe passes through the rubber tube sleeve. A pressure sensor is installed on the output pipe and close to the rubber tube sleeve, with the detection end of the pressure sensor located inside the output pipe. A frequency converter is installed in the water supply chamber directly below the pressure sensor via screws.

[0006] By adopting the above technical solution, the intelligent variable frequency constant pressure water supply equipment based on multiple pumps in parallel can easily separate the detection and control components from the pump body, avoid mutual interference, and simultaneously reduce the temperature of multiple sets of intelligent variable frequency pump bodies, achieving a rapid cooling effect.

[0007] Specifically, the detection end of the thermostat is located inside the cooling chamber, the output end of the thermostat is electrically connected to the input end of the air cooler via a wire, and the output port of the air cooler is connected to the cooling chamber via a pipe.

[0008] By adopting the above technical solution, the operation of the air cooler is automatically controlled by the thermostat. When the temperature in the water supply chamber is high and exceeds the set value of the thermostat, the air cooler will be automatically controlled to work.

[0009] Specifically, the inlet of the intelligent variable frequency pump body is connected to an input pipe, and both the input pipe and the output pipe pass through the reserved hole on the water supply chamber.

[0010] Specifically, connecting blocks are welded to the top of both ends of the water supply chamber, and the connecting blocks are fixed to the cover plate by connecting bolts.

[0011] Specifically, the output and input terminals of the frequency converter are electrically connected to the input terminal of the intelligent frequency converter pump body and the output terminal of the pressure sensor via wires.

[0012] By adopting the above technical solution, the pressure sensor converts the pressure inside the output pipe into an electrical signal, which is then transmitted to the frequency converter. The frequency converter calculates the pressure deviation through a PID algorithm, automatically adjusts the output frequency, and changes the speed of the intelligent variable frequency pump body, so that the actual pressure approaches the set value.

[0013] Specifically, a discharge pipe is provided at one end of the water supply chamber and on the side facing the intelligent variable frequency pump body. A discharge valve is provided on the discharge pipe. Heat dissipation mesh openings are embedded at both ends of the water supply chamber.

[0014] The beneficial effects of this utility model are: The present invention relates to an intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel. The pressure sensor converts the pressure in the output pipe into an electrical signal, which is transmitted to the frequency converter. The frequency converter calculates the pressure deviation through a PID algorithm, automatically adjusts the output frequency, and changes the speed of the intelligent variable frequency pump to make the actual pressure approach the set value. A baffle is used to isolate the intelligent variable frequency pump from the pressure sensor and frequency converter on the output pipe to avoid mutual interference. When water leakage occurs when the intelligent variable frequency pump is connected to the pipe, the liquid accumulates in the chamber where the intelligent variable frequency pump is installed. The drain valve is opened and the accumulated liquid is discharged through the drain pipe.

[0015] The present invention describes an intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel. It uses a thermostat to automatically control the operation of the air cooler. When the temperature in the water supply chamber is high and exceeds the set value of the thermostat, the air cooler will automatically start. The blown cold air enters the cooling chamber and is finally dispersed into the water supply chamber. At the same time, it reduces the temperature of multiple sets of intelligent variable frequency pumps, achieving a rapid cooling effect and preventing heat buildup in the machine body, which could cause damage.

Figure 1-3 As shown, the present invention provides an intelligent variable frequency constant pressure water supply device based on multiple pumps in parallel, including a water supply chamber 3 and a cover plate 6. The top of the water supply chamber 3 is fitted with the cover plate 6.

A cool air fan 8 is installed on the top of the cover plate 6 and at one end of the cooling chamber 7 by a mounting base. A partition plate 13 is welded inside the water supply chamber 3. A smart variable frequency pump body 11 is installed at equal intervals on one side of the partition 13 within the water supply chamber 3 via a mounting base. Rubber tube sleeves 12 are fitted at equal intervals on the partition 13 via mounting holes. The outlet of the smart variable frequency pump body 11 is connected to an output pipe 15, and the output pipe 15 passes through the rubber tube sleeve 12. A pressure sensor 14 is installed on the output pipe 15 and close to the rubber tube sleeve 12, with the detection end of the pressure sensor 14 located inside the output pipe 15. A frequency converter 16 is installed in the water supply chamber 3 directly below the pressure sensor 14 via screws.

[0021] When in use, the intelligent variable frequency constant pressure water supply equipment based on multiple pumps in parallel can easily separate the detection and control elements from the pump body to avoid mutual interference, and at the same time reduce the temperature of multiple sets of intelligent variable frequency pump bodies 11, so as to achieve a rapid cooling effect.

[0022] For example, such as Figure 1As shown, the present invention also includes the following: the detection end of the thermostat 9 is located inside the cooling chamber 7; the output end of the thermostat 9 is electrically connected to the input end of the air cooler 8 via a wire; and the output port of the air cooler 8 is connected to the cooling chamber 7 via a pipe.

[0023] When in use, the temperature controller 9 automatically controls the operation of the air cooler 8. When the temperature in the water supply chamber 3 is high and exceeds the set value of the temperature controller 9, the air cooler 8 will automatically operate.

[0024] For example, such as Figure 1 , 2 As shown, the present invention also includes an input pipe 10 connected to the water inlet of the intelligent variable frequency pump body 11, and the input pipe 10 and the output pipe 15 both pass through the reserved hole on the water supply chamber 3.

[0025] During use, both the inlet pipe 10 and the outlet pipe 15 pass through the pre-drilled holes in the water supply chamber 3, facilitating the use of external connections.

[0026] For example, such as Figure 1 , 2 As shown, the present invention also includes connecting blocks 5 welded to the top of both ends of the water supply chamber 3, and the connecting blocks 5 are fixed to the cover plate 6 by connecting bolts 4.

[0027] When in use, the connecting block 5 and connecting bolt 4 are used to fix the cover plate 6 to the water supply chamber 3, which facilitates installation and disassembly.

[0028] For example, such as Figure 1 , 2 As shown, the present invention also includes that the output terminal and input terminal of the frequency converter 16 are electrically connected to the input terminal of the intelligent frequency converter pump body 11 and the output terminal of the pressure sensor 14 respectively via wires.

[0031] When in use, open the drain valve 2 and use the drain pipe 1 to discharge the accumulated liquid.

[0032] In use, the pressure sensor 14 converts the pressure in the output pipe 15 into an electrical signal and transmits it to the frequency converter 16. The frequency converter 16 calculates the pressure deviation through a PID algorithm, automatically adjusts the output frequency, and changes the speed of the intelligent variable frequency pump body 11 so that the actual pressure approaches the set value. The partition 13 isolates the intelligent variable frequency pump body 11 from the pressure sensor 14 and the frequency converter 16 on the output pipe 15 to avoid mutual interference. When water leaks when the intelligent variable frequency pump body 11 is connected to the pipe, the liquid accumulates in the chamber where the intelligent variable frequency pump body 11 is installed. The drain valve 2 is opened and the accumulated liquid is discharged through the drain pipe 1. The temperature controller 9 automatically controls the operation of the air cooler 8. When the temperature in the water supply chamber 3 is high and exceeds the set value of the temperature controller 9, the air cooler 8 will automatically operate. The blown cold air enters the cooling chamber 7 and is finally dispersed into the water supply chamber 3, thereby reducing the temperature of multiple sets of intelligent variable frequency pump bodies 11, achieving a rapid cooling effect and preventing heat buildup in the machine body, which could cause damage.
