Abstract

The rotor data including a model name, a maximum rotating speed, and a rotor identification number of a rotor that is purchased after installation, for example, is stored through the inputting unit in an EEPROM in addition to the rotor data that was stored in the ROM before shipping. The inputted rotor data is displayed on the display in a list image together with the rotor data of the rotor data in the ROM to provide easily selection of the rotor. The inputted rotor data may be displayed with priority to the rotor data in the ROM. The rotor data may further include check data. It may be judged that the inputted rotor data is correctly inputted. If the rotor data is incorrectly inputted, an error message is displayed and the rotary data is not stored. If the rotor data is correctly inputted, the rotary data is registered in the RAM.

Claims

1. A centrifugal separator comprising:

a motor for rotating one of first rotors and second rotors;

input means for inputting model names of said first rotors;

first memory means, who is writable and readable, for storing said model names of said first rotors; and

second memory means, which is read-only type, for storing model names of said second rotors in advance,

display means for displaying data and for displaying said model names of said first rotors and said second rotors from said first memory means and said second memory means in a list image.

2. A centrifugal separator as claimed in claim 1, wherein each of said model names of said first rotors and said second rotors, which are displayed by said display means, includes maximum rotating speed data corresponding to each of said first rotors and said second rotors, rotation radius data corresponding to said each of said first rotors and said second rotors, and rotor identification number data corresponding to said each of said first rotors and said second rotors.

3. A centrifugal separator as claimed in claim 1, wherein said first memory means comprises an EEPROM.

4. A centrifugal separator as claimed in claim 1, wherein said display means displays said model names of said first rotors with priority to said model names of said second rotors.

5. A centrifugal separator as claimed in claim 1, wherein said display means displays said model names of said first rotors and said model names of said second rotors at different areas on said list image, respectively.

6. A centrifugal separator as claimed in claim 1, wherein

each of said model names of said first rotors and said second rotors includes type data of each of said first rotors and said second rotors,

said centrifugal separator further comprising:

arranging means for classifying each of said model names of said first rotors and said second rotors into classes in accordance with each of said type data and arranging said model names of said first rotors and said second rotors in each class in order of the maximum rotating speed, wherein

said display means display said model names of said first rotors and said second rotors in said each class in order of the maximum rotating speed in said list image.

7. A centrifugal separator comprising:

a motor for rotating one of first rotors and second rotors;

input means for inputting first data of said first rotors;

first memory means, which is writable and readable, for storing said first data; and

second memory means, which is read-only type, for second data of said second rotors in advance,

display means for displaying data and for displaying said first data of said first memory means with priority to said second data from said second memory means.
