MAGNETIC POWER LOSS OF MAGNETIC DRIVING SUBMERSIBLE PUMP

摘要

We designed the magnetic driving submersible pump (MDSP) to substitute ordinary one. Because of the eddy current and stray field, the power loss of the MDSP was increased 11-15% and these problems drop down the pump life same time because of the property of permanent magnets becoming worse by ultra warm. It can decrease the power loss 5-10% and magnetic materials volume 13% to use the optimizing magnetization permanent magnets to obtaining the maximal gradient force. There are 8 or more times longer life of the MDSP than the ordinary one.
