[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] This ethylene glycol precise metering and conveying pump can precisely control the flow rate and conveying volume of the liquid, ensuring that the amount of ethylene glycol conveyed each time is very consistent. This is particularly important for industrial processes that require strict control of chemical reactions or formulations.

[0020] Embodiment

[0021] Please refer to Figures 1 - 4 As shown, this embodiment provides an ethylene glycol precise metering delivery pump, including a pump body assembly 1. The pump body assembly 1 includes a pump housing 10. There is a cavity 12 inside the pump housing 10. A first baffle 15 is rotatably connected to the lower part of the cavity 12. The first baffle 15 rotates unidirectionally into the cavity 12. When the first baffle 15 is opened, ethylene glycol enters it. One end of the pump housing 10 where the first baffle 15 is transferred is rotatably connected to a second baffle 18. The second baffle rotates outward. When the second baffle is opened, ethylene glycol is pumped out of the cavity 12. A fixing ring 19 is fixedly connected inside the cavity 12. The fixing ring 19 is used to prevent the second baffle from rotating in the reverse direction. The upper surface of the pump housing 10 is fixedly connected with a power assembly 2. The power assembly 2 includes a partition 22. One end of the partition 22 is fixedly connected with a servo motor 21. The output shaft of the servo motor 21 is fixedly connected with an eccentric wheel 23. The eccentric wheel 23 is rotatably connected with a connecting rod 24 at a position deviating from the axis. The other end of the connecting rod 24 is rotatably connected with a piston 25. The piston 25 pumps ethylene glycol through its up and down movement.

[0022] The above working principle: The lower part of the cavity 12 is equipped with a first baffle 15. This first baffle 15 can rotate unidirectionally, allowing ethylene glycol to enter the cavity 12 when the first baffle 15 is opened. One end of the pump housing 10 is also equipped with a second baffle 18. This second baffle 18 is used to pump ethylene glycol out of the cavity 12. When the second baffle 18 rotates outward, it will discharge ethylene glycol from the cavity 12. In order to prevent the second baffle 18 from rotating in the reverse direction when not working, a fixing ring 19 is arranged inside the cavity 12 to ensure that the second baffle 18 can only rotate in the correct direction. The power assembly 2 is fixed on the upper surface of the pump housing 10, which includes a servo motor 21. The motor is connected to an eccentric wheel 23 through the output shaft. The eccentric wheel 23 is connected to a connecting rod 24 at a position deviating from the axis. The other end of the connecting rod 24 is connected with a piston 25. The servo motor 21 drives the eccentric wheel 23 to rotate, driving the connecting rod 24 and the piston 25 to move up and down. The up and down movement of the piston 25 realizes the effective pumping of ethylene glycol, enabling the pump to precisely control the liquid flow rate and delivery volume, thus meeting the precise metering requirements in the industrial process.

[0023] In order to facilitate the connection of pipelines, therefore, in this embodiment, a fixing frame 11 is fixedly connected to the lower surface of the pump housing 10. The fixing frame 11 is used to fix the device. A water inlet pipe 13 is fixedly connected to the surface of the pump housing 10. One end of the water inlet pipe 13 is fixedly connected with a first connection seat 14. A water outlet pipe 16 is also fixedly connected to the surface of the pump housing 10. One end of the water outlet pipe 16 is fixedly connected with a second connection seat 17. Bolts are passed through the fixing frame 11 to fix the pump body. When connecting the pipeline to the pump body, by connecting the first connection seat 14 and the second connection seat 17 on the water inlet pipe 13 and the water outlet pipe 16, the device can be connected to the pipeline to pump ethylene glycol.

[0024] To facilitate the heat dissipation of the motor, in this embodiment, a protective shell 20 is fixedly connected to the upper surface of the pump housing 10. A number of ventilation holes are provided on the upper surface of the protective shell 20 to dissipate heat from the servo motor 21. The heat generated during the operation of the motor is discharged through the ventilation holes, increasing the service life of the pump body.

[0025] To enhance the service life of the transfer pump, in this embodiment, a sealing ring 26 is sleeved on the surface of the piston 25. The sealing ring 26 is made of alloy material. Since ethylene glycol is a corrosive chemical, corrosion-resistant materials and sealing technologies are adopted to ensure the long-term stability and safety of the pump.

[0026] When the ethylene glycol precise metering transfer pump in this embodiment is specifically used, first, bolts are passed through the fixing frame 11 to fix the pump body. When connecting the pipeline to the pump body, the device can be connected to the pipeline to pump ethylene glycol by connecting the first connecting seat 14 and the second connecting seat 17 on the water inlet pipe 13 and the water outlet pipe 16. A first baffle 15 is provided at the lower part of the cavity 12. This first baffle 15 can rotate unidirectionally, allowing ethylene glycol to enter the interior of the cavity 12 when the first baffle 15 is opened. A second baffle 18 is also installed at one end of the pump housing 10. This second baffle 18 is used to pump ethylene glycol out of the cavity 12. When the second baffle 18 rotates outwards, it will discharge ethylene glycol from the cavity 12. To prevent the second baffle 18 from rotating in the reverse direction when not working, a fixing ring 19 is provided in the cavity 12 to ensure that the second baffle 18 can only rotate in the correct direction. The power assembly 2 is fixed on the upper surface of the pump housing 10, including a servo motor 21. The heat generated during the operation of the motor is discharged through the ventilation holes, increasing the service life of the pump body. The motor is connected to an eccentric wheel 23 through an output shaft. One end of the eccentric wheel 23 deviating from the axis is connected to a connecting rod 24, and the other end of the connecting rod 24 is connected to a piston 25. The servo motor 21 drives the eccentric wheel 23 to rotate, driving the connecting rod 24 and the piston 25 to move up and down. The up and down movement of the piston 25 realizes the effective pumping of ethylene glycol. Since ethylene glycol is a corrosive chemical, corrosion-resistant materials and sealing technologies are adopted to ensure the long-term stability and safety of the pump, enabling the pump to accurately control the flow rate and delivery volume of the liquid, thus meeting the precise metering requirements in industrial processes.
