The laboratory centrifuge safety protection system consists of main current protection, over temperature protection, over speed protection, unbalance protection and door cover safety protection.
1. Main current protection: When the power supply current exceeds the rated value, the main unit is powered off.
2 , over temperature protection: When the temperature exceeds the preset temperature ± 6 ° C , the motor stops running.
3. Overspeed protection: When the speed is out of control or exceeds the preset speed ±300rpm , the motor stops running.
4. Unbalance protection: When the centrifuge generates vibration due to unbalanced operation and its amplitude exceeds a certain amount, the motor stops running.
5 , door cover safety protection: When the door cover is not covered to start the centrifuge, the motor cannot be started. The door is forcibly opened during the operation of the centrifuge, and the motor stops running.
