Eddy excitation type adjustable type magnetic pump and working method thereof

Abstract

The invention discloses an eddy excitation type adjustable type magnetic pump comprising a motor, a drive shaft, an outer magnetic rotor, an auxiliary magnetic disk, a first casing, a second casing, an inner magnetic rotor, a linkage shaft, an impeller and an end cover. The drive shaft is arranged at one end of the motor, the outer magnetic rotor is connected to the output end of the drive shaft,the first casing is arranged on the outer side of the drive shaft, the second casing is fixedly arranged on one side of the first casing, one side of the second casing is close to the outer magnetic rotor, and the other side of the second casing is provided with the inner magnetic rotor; the linkage shaft is arranged in the center of the inner magnetic rotor, the impeller is arranged at the outputend of the linkage shaft, the end cover is arranged on the outer side of the impeller, and the auxiliary magnetic disk is arranged on the second casing; a sealing mechanism is further included; a working method of the magnetic pump is also disclosed; on one hand, the auxiliary magnetic disk is used for adjusting the output power of the motor, output adjustment of the device is realized, the device output accuracy is high, and the practicality is high; and on the other hand, multiple sealing is adopted, the sealing performance is high, and the safety performance is high.

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-...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the current magnetic pumps have the problem that the output power is not high and cannot be adjusted. The output accuracy is poor. At the same time, they cannot adapt to various output environments and have poor practicability.

[0006] 2. Most of the current magnetic pumps have the problem of poor sealing, the fluid is easy to leak, and the safety performance is poor
