Problems solved by technology

[0003] When the magnetic pump in the prior art uses a metal spacer, the spacer is in a sinusoidal alternating magnetic field, and eddy current is induced on the section perpendicular to the direction of the magnetic force line and converted into heat, which will affect the normal operation of the magnetic pump. result in negative effect
When the medium conveyed by the magnetic pump in the prior art contains solid particles, the particles arrive at the isolation sleeve along with the medium, and the high-speed rotation of the inner magnetic rotor will drive the medium and solid particles to rotate at high speed, and the solid particles will be thrown to the The isolation sleeve, causing solid particles to rub against the isolation sleeve at high speed, will be eroded under long-term work and cause damage to the isolation sleeve

Abstract

The invention discloses an all-composite-carbon-fiber magnetic pump, and belongs to the technical field of liquid delivery pumps. The all-composite-carbon-fiber magnetic pump comprises a base body portion, a power portion, a pump body portion and a transmission portion, and is characterized in that a pump spindle (5) and an inner magnetic rotor (8) are wrapped by an isolation sleeve (10) made of all composite carbon fibers. The magnetic pump is made of non-metallic materials instead of metallic materials, magnetic action is not generated on the isolation sleeve in a magnetic field, and further eddy current is not inducted, so that the purpose of reducing the eddy current is achieved.

Description

technical field [0001] The invention belongs to the technical field of liquid conveying pumps, and more specifically, belongs to a fully composite carbon fiber magnetic pump. Background technique [0002] The prior art magnetic pump consists of three parts: a centrifugal pump, a magnetic drive, and an electric motor. The magnetic drive is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic substances, and drive the inner magnetic rotor connected to the impeller to rotate synchronously, realizing the non-contact transmission of power and converting the dynamic seal into a static seal. [0003] When the magnetic pump in the prior art uses a metal spacer, the spacer is in a sinusoidal alternating magnetic field, and eddy current is induced on the section perpendicular to the direction of the magnetic force line an...
