12. Hydraulic component capacity measure experiment
1. Experiment workbench inlet wire should connect correct, and ensure connect to ground
connection is good.
2. When use it, your hands should keep dry, clean. Don’t use sharp tools to touch
3. When do experiment, connect circuit correct, you should ask teacher, after teacher’s confirm, you can connect power supply. It is forbid use hand or electric conduction touch electrical part. If you unprofessional operation , you should be responsible for your action.
4. When after experiment, you should cut off main power supply, make breaker handle to down direction.
5. When transformer experiment, forbid use hand touch rotary part. When connect to power supply and do experiment, don’t exceed motor rated voltage, and rated power range.
6. There is measurement meter in workbench panel, when use, don’t exceed its range.
7. When met emergency condition, you can press emergency stop button, breaker will automatically cut off power supply. When remove emergency situation, you should press reset button, then you can connect to power supply again, or breaker can’t work normal. It is forbid to connect power supply force.
8. When do transformer disassembly experiment, be careful of sharp steel sheet, steel belt, you should wear glove, or take measures to protect your hands.
