Description

technical field [0001] The invention belongs to the field of intelligent manufacturing, and in particular relates to an eddy current excitation adjustable magnetic pump and a working method thereof. Background technique [0002] The magnetic pump first appeared in the 1930s and 1940s, and has continued to develop since then, and has been in great demand in the market. The magnetic pump is a branch of the water pump field, and it is a new product that applies the working principle of the permanent magnetic coupling to the centrifugal pump. Nowadays, there are more than 600 domestic pump manufacturing enterprises in my country, with an annual output value of nearly 20 billion, and it is continuously rising. Magnetic pumps have a very wide range of applications, the smallest can be as small as building municipalities, and the largest can reach nuclear power and aerospace, and the market applications are extremely extensive. [0003] However, the current market for high value-...
