Title:
遠心分離機の回転速度を速やかに減速させる方法および装置
Document Type and Number:
Japanese Patent JP3874725
Kind Code:
B2
Abstract:
In a method of rapidly lowering the rotary speed of a rotating rotor body in a centrifugal separator the lowering of the rotary speed is initiated, when a disturbing unbalance or vibrations have occurred. A space between the rotor body and a stationary casing which surrounds the rotor body is supplied with foam or with an aerosol of a liquid in a gas, when unbalance or vibrations over a certain level have occurred. The rotor body is retarded by the friction, which is obtained between the rotor body, the foam or aerosol and the casing. In an arrangement to lower the rotary speed of a rotating rotor body in a centrifugal separator the lowering is initiated when a disturbing unbalance or disturbing vibrations has occurred. At a certain unbalance or certain vibration level, a foam generating device or a device that creates an aerosol for the purpose of filling a space between the rotor body and a casing which surrounds the same with foam or aerosol is activated.
