Description

TECHNICAL FIELD

[0001] The utility model relates to laboratory equipment centrifuge technical field, specifically, relate to a centrifuge through color identification rotor operating state. BACKGROUND

[0002] Laboratory centrifuge, or experimental centrifuge, is a small centrifuge used for professional experimental analysis. The centrifuge is an object rotating around a fixed rotating shaft, which is subjected to centrifugal force to simulate the action of the earth's gravitational field, so that the object does the sedimentation, thereby separating the different density and different molecular t of the material. The technology of applying centrifugal sedimentation to the analysis and separation of matter is called centrifugal technology. At present, various centrifuges and centrifugal technology have been widely used in scientific research and production departments, and have become one of the important instruments and equipment in modern scientific research. Laboratory centrifuge is the necessary equipment for scientific research and production in biology, medicine, agronomy, bioengineering, biopharmaceutical industry and other industries.

[0003] The current technical field part of the equipment due to lack of technology or cost constraints or because of the use of way or internal structure and other restrictions can not add rotor identification function. The main purpose of identifying the rotor is to ensure the safety of the machine. The rotor identification function can ensure that the centrifuge does not exceed its limit speed when running, so as to avoid serious accidents caused by high speed, such as rotor deformation, cracking and even fragmentation, which may cause great personal injury to the operator.

[0004] Specifically, each centrifuge rotor has its own limit speed. If the operator sets a speed higher than the limit speed, the system will automatically correct the set speed to ensure that it runs within the safe range and remind the operator that the set speed exceeds the safe range. In addition, the rotor identification function can also record the running time of each rotor, and will remind the operator to replace the new rotor when the allowed running time is exceeded, thus replacing the previous manual recording method. Therefore, the application of rotor identification technology not only improves the safety of the equipment, but also simplifies the operation process and reduces the possibility of human error.

[0005] It is known that the rotor identification method of laboratory centrifuge includes Hall induction identification, which mainly works through the magnetic force of magnetic steel and Hall induction. The Hall and magnetic steel sensing method has a large error due to the change of magnetic force, Hall induction distance and other factors. There is often a lot of vibration in the work of centrifuge, which often leads to sensing error and alarm, which greatly affects the work efficiency.

[0006] In view of the above problems, how to improve the work efficiency of laboratory centrifuge has become a technical problem that people need to solve urgently. Utility model content
