Abstract

The invention discloses a stepless speed-regulating centrifugal pump utilizing the principle of permanent magnet transmission, which includes a base, a slide rail is arranged on the upper surface of the base, and a motor fixedly connected to the lower surface of the first motor is clamped in the slide rail. A slider, the upper surface of the first motor is fixedly connected with a fixed block, the surface of the fixed block is provided with a threaded hole, the upper surface of the base is fixedly connected with a bracket, and the upper surface of the bracket is fixedly connected with a second The motor, the output end of the second motor is fixedly connected with a threaded rod through a shaft coupling, the threaded rod is threadedly connected with the threaded hole, and the upper surface of the base is fixedly connected with a support. The present invention realizes that through the rotation of the second motor, the linkage threaded rod rotates, and the threaded rod rotates in the threaded hole, so that the fixed block moves axially along the threaded rod, thereby driving the first motor to move, so that the active rotor and the slave The size of the air gap formed between the moving rotors changes, thereby achieving the purpose of stepless speed regulation.

Description

technical field [0001] The invention relates to the technical field of permanent magnet transmission, in particular to a stepless speed-regulating centrifugal pump utilizing the principle of permanent magnet transmission. Background technique [0002] The permanent magnet transmission technology uses magnetic force to drive the load to achieve non-contact torque transmission between the motor and the load. The active rotor driven by the motor rotates at high speed, cutting the magnetic field lines in the magnetic field generated by the driven rotor, thereby generating an induced magnetic field. Through the magnetic field The interaction force between them drives the load to work and realizes the transmission of torque. [0003] Permanent magnet transmission technology is widely used in power transmission. Centrifugal pumps are a kind of machinery that we often use. Applying permanent magnet transmission technology to centrifugal pumps can directly prevent centrifugal pumps f...
