Centrifugal fluid pump apparatus |
摘要 |
A centrifugal fluid pump apparatus includes a control mechanism; and a body 5 including a pump section having an impeller rotating inside a housing; a rotor having an impeller attraction magnet; a motor for rotating the rotor; an impeller attraction electromagnet for attracting the impeller thereto; an impeller-position detection sensor; and a groove for hydrodynamic bearing provided on an inner surface of the housing. The control mechanism has a position sensor output monitoring function or an electromagnet current monitoring function, a motor current monitoring function; and an emergency impeller rotation function. The impeller rotation function operates when the sensors or the electromagnet has a failure by using the position sensor output monitoring function or the electromagnet current monitoring function to rotate the impeller by utilizing the groove for hydrodynamic bearing. |
