Technical Field

[0001] The invention relates to the technical field of electromagnetic pumps, in particular to a transmission mechanism for liquid metal. Background Art

[0002] The electromagnetic pump is a chemical process pump that uses modern magnetic mechanics principles and permanent magnets to achieve contactless indirect transmission. When the motor drives the outer rotor assembly to rotate, the magnetic field lines pass through the isolation sleeve to drive the inner rotor assembly and the impeller to rotate synchronously. The medium is completely enclosed in the static isolation sleeve, thereby achieving the purpose of leak-free pumping of the medium, completely solving the shaft seal leakage of mechanical transmission pumps, and is a new type of industrial pump that is fully sealed, leak-free, and pollution-free.

[0003] With the advancement of technology, many are now using coreless electromagnetic pumps as a tool for transferring liquid metal. The existing coreless electromagnetic pumps can transmit very well and are highly efficient. However, when installing the existing coreless electromagnetic pumps, due to the different factory environments, the ground where the coreless electromagnetic pumps are installed may not be level, causing the working state of the coreless electromagnetic pumps to not reach a level state. There is no big problem in short-term use, but for a long time, the impact force of the liquid metal inside the coreless electromagnetic pump may cause damage to the coreless electromagnetic pump.
