IPC: B04B13/00
Filed: 1995-03-31
Abstract: PURPOSE: To shorten a centrifugal separation time to enhance work efficiency, in a centrifugal separator equipped with a vacuum pump and a vacuum meter, by calculating a vacuum degree permitting the rotation of a rotary body on the basis of the set number of rotations and performing acceleration control up to the set number of rotations after reaching a predetermined vacuum degree. CONSTITUTION: In a centrifugal separator, the relation between the set number of rotations and a rotatable vacuum degree is inputted to a CPU 7 and an operator sets a rotary body 2 on the drive motor 3 in a rotary body chamber 1 and a temp. sensor 6 measures the temp. of the rotary body 2 on the drive motor 3. When the operator inputs operation conditions such as the number of rotations, temp. or the like through an operation panel 4, the CPU 7 calculates the rotary vacuum degree on the basis of the inputted number of rotations.  When the vacuum drawing in the rotary body chamber 1 is started, the vacuum degree in the rotary body chamber 1 is measured by a vacuum meter 5 and, when the vacuum degree in the rotary body chamber 1 reaches the calculated vacuum degree, a current flows to a drive motor 3 and the rotary body 2 is rotated to be subjected to accelation control up to the set number of rotations.
