The front end of the air inlet pipe 15 is fixedly connected to the air delivery pipe 14. An air outlet pipe 16 is fixedly connected to the lower rear position of the sleeve 7.
[0026] The pump body 1 is a cylindrical pump. A water suction pipe is provided at the middle position of the bottom of the pump body 1. The exhaust pipe 3, the drain pipe 4, the air inlet pipe 15 and the air outlet pipe 16 are all horizontally distributed pipes. The air delivery pipe 14 is a "U"-shaped bent pipe. The air inlet pipe 15 and the air outlet pipe 16 can enable air circulation between the sleeve 7 and the outside. The limiting plate 5 is a horizontally distributed circular ring plate. The limiting plate 5 is provided with a plurality of bolt connection holes. The inner side of the limiting plate 5 is in contact with the pump body 1. The lower opening of the sleeve 7 can be sealed by the limiting plate 5. The first heat dissipation fins 6 are evenly distributed at the bottom of the limiting plate 5. The first heat dissipation fins 6 are all in an "L" shape. The opposite inner sides of the first heat dissipation fins 6 are in contact with the pump body 1, which can improve the heat dissipation effect. The bottom of the sleeve 7 is provided with a plurality of bolt connection holes. Connection holes are provided at the upper front position and the lower rear position of the sleeve 7. A fixing groove is provided at the top of the sleeve 7 to fix the heat conduction plate 8. The bottom of the heat conduction plate 8 is in contact with the pump body 1. The heat conduction plate 8 has high thermal conductivity. The second heat dissipation fins 9 are all vertically distributed. The second heat dissipation fins 9 are evenly distributed at the top of the heat conduction plate 8, which can further improve the heat dissipation effect. The temperature sensor 10 is located below the partition plate 11 and the sealing strip 12. The rear end of the temperature sensor 10 is in contact with the pump body 1. The partition plate 11 is a spiral metal plate. The sealing strip 12 is a spiral rubber strip. The inner side of the sealing strip 12 is in contact with the pump body 1, and the internal space of the sleeve 7 can be divided into a spiral flow track.
[0027] Workflow: The pump body 1 of the device is fixed in place by the support legs 2. The right end of the drain pipe 4 of the device is connected to the reservoir through a pipeline. Before use, the power supply is turned on. The pump body 1, temperature sensor 10, and small air pump 13 of the device are all electrical instruments. The device is equipped with an external controller, and the operating states of the pump body 1, temperature sensor 10, and small air pump 13 can be adjusted by manually operating the external controller. The above are all prior arts. When using the device, first start the pump body 1 and temperature sensor 10 through the external controller. The pump body 1 sucks in the water-gas mixture through the bottom suction pipe, discharges the gas through the exhaust pipe 3, and discharges the liquid into the reservoir through the drain pipe 4. When the pump body 1 is used for a long time, it will generate heat. The temperature of the pump body 1 can be detected by the temperature sensor 10 that fits with the pump body 1, and the temperature measured by the temperature sensor 10 can be displayed by the external controller. The casing 7 of the device is bolted to the limit plate 5. After the casing 7 and the limit plate 5 are connected, the first heat dissipation fins 6 fit with the bottom and the lower half curved surface of the pump body 1. The heat conduction plate 8 fixedly connected to the casing 7 fits with the top of the pump body 1, and the limit plate 5 seals the bottom of the casing 7, so that the casing 7 can only have air flow through the intake pipe 15 and the exhaust pipe 16. Since the partition plate 11 is fixed to the casing 7 and the sealing strip 12 fits with the pump body 1, the internal space of the casing 7 can be divided into a spiral flow track by the partition plate 11 and the sealing strip 12. When the temperature of the pump body 1 is relatively high, manually operate the external controller to start the small air pump 13. The small air pump 13 can suck in external air and discharge it into the casing 7 through the air delivery pipe 14 and the intake pipe 15. The air flows spirally downward along the track formed by the partition plate 11 and the sealing strip 12 inside the casing 7 and finally discharges through the exhaust pipe 16. The temperature sensor 10 does not contact the partition plate 11, and the temperature sensor 10 will not block the air flow. Through the small air pump 13, efficient air exchange can be carried out inside the casing 7, which can effectively reduce the temperature. At the same time, the heat is conducted to the second heat dissipation fins 9 through the heat conduction plate 8, and the second heat dissipation fins 9 and the first heat dissipation fins 6 can be used for auxiliary cooling. The device divides the internal space of the casing 7 through the partition plate 11 and the sealing strip 12, injects air into the casing 7 through the small air pump 13 and the air delivery pipe 14, so that efficient air exchange is carried out inside the casing 7 to achieve the purpose of cooling. The device has a good heat dissipation effect, so that the vortex well self-priming pump will not overheat during long-term operation, which can ensure the service life of the equipment and prevent the equipment from shutting down due to overheating.
