Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, and in particular to a magnetic pump with backwashing function. Background Technology

[0002] A magnetic drive pump is a fluid transport device that achieves contactless transmission through a magnetic coupling. The rotational motion of the electric motor is transmitted to the inner magnetic rotor inside the isolation sleeve through the outer magnetic rotor, which drives the impeller to rotate and complete the medium transport. Because a static sealing isolation sleeve is used between the pump shaft and the pump casing, the shaft seal leakage problem of traditional mechanical pumps is completely solved. It has the characteristics of no leakage, low noise, high efficiency and easy maintenance, and is widely used in chemical, pharmaceutical, environmental protection and other scenarios for transporting corrosive, toxic and harmful media with high sealing requirements.

[0003] Current methods for cleaning the internal components of magnetic pumps require first disconnecting the power supply, depressurizing, and preparing specialized tools and suitable cleaning agents. Then, the pump body, impeller, magnetic rotor, and isolation sleeve components are disassembled. Neutral cleaning agents are used in conjunction with soft tools to remove impurities and crystals from the impeller flow channel, the inner wall of the pump casing, and the surface of the magnetic rotor. The cleaning process is frequent and the disassembly procedure is complex, resulting in reduced maintenance efficiency. Utility Model Content

The end of magnetic device 3 furthest from motor 1 is fixedly connected to pump casing 4, while the end of magnetic device 3 closest to pump casing 4 is fixedly connected to impeller 10. This impeller generates effective centrifugal force on the liquid during rotation, enabling the liquid to acquire sufficient kinetic and pressure energy. An outlet pipe 11 is fixedly connected to the top of pump casing 4 to ensure smooth liquid discharge. An inlet pipe 5 is fixedly connected to the left side of pump casing 4 to ensure… Liquid can stably enter the pump casing 4. A liquid delivery pipe 25 is fixedly connected to the outer wall of the pump casing 4. A bidirectional nozzle 9 is fixedly connected to one end of the liquid delivery pipe 25 inside the pump casing 4. This nozzle thoroughly cleans the impurities attached to the surface of the impeller 10 and the inner wall of the pump casing 4.
