1: Before starting the pump, check whether all valves are in the correct position.
Make sure that the valves on the designed flow path are open, while other valves, such as the drain valve and the drain valve, should be closed.
2: If you want to start a pump remotely, for example from the control room, make sure that the pump you are about to start is ready to start.
If you are not sure, you should go to the scene to check, or ask others to check.
3: Make sure that: The key steps that are critical to the safe operation of the pump, including the switch position of the valve, must be included in the equipment's operating procedures and checklist.
4: Some pumps are automatically started.
E.g:
(1): When the storage tank is full, the process control computer or liquid level control instrument will automatically empty the storage tank.
(2): Before putting these pumps into automatic control, such as after maintenance, make sure that all valves are in the correct position.
5: In order to prevent starting the pump when the pipeline is disconnected, some pumps are equipped with instrument protection devices-for example, low flow, high temperature, or overpressure interlock. Make sure that these safety systems are properly maintained and tested.
