Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pump equipment, in particular to an anti-blocking magnetic pump. Background Art

[0002] A magnetic pump primarily consists of three parts: the pump, the magnetic transmission, and the motor. The magnetic transmission is the key component, consisting of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. During operation, the motor rotates the outer magnetic rotor. The magnetic field penetrates air gaps and non-magnetic materials, driving the inner magnetic rotor, connected to the impeller, to rotate synchronously, achieving contactless power transmission. This transmission method transforms a leak-prone dynamic seal into a zero-leakage static seal, completely eliminating the problems of "escape, bubbling, dripping, and leakage," making it widely used in various applications requiring leak-free liquid transportation. However, when magnetic pumps transport liquids with high viscosity or high levels of impurities, blockages often occur. This is primarily caused by the liquid agglomerating on the inner wall of the pipe. Traditional electromagnetic pumps lack cleaning and anti-blocking functions, requiring frequent disassembly and maintenance, which is time-consuming and labor-intensive. A new type of magnetic pump is needed to address this problem. Utility Model Content
