Lubricating oil pump of the circulation machine
Thread Content
For the lubrication oil pumps of the circulation machines, one is in operation while the other is in standby mode. I would like to ask whether both the operating and the standby pumps are set to the automatic mode? Is it the manual backup that’s running, or the automatic one?
All operations must be carried out in accordance with the device’s operating instructions, and questions cannot be left unresolved here. Due to the variations in automated control, this is provided for reference only.
After the switch is complete, both units can be set to automatic mode. You actually know the reason why you asked this question.
The standby pump definitely needs to be set to automatic mode
Generally, the standby pump is set to automatic mode, while for the pump that is in operation, our unit usually uses manual mode.
First, it is necessary to examine how the interlock logic for starting the pump is implemented. Generally, electrical and mechanical requirements dictate that the pump should be inspected and rotated manually before it is started; therefore, the pump to be started must be set to manual mode. Once the pump has started and interlock conditions such as outlet pressure and motor operation signals are met, the standby pump can then be set to automatic mode.
It is mainly to address mistakes in operation; the ability to raise such questions on the front line and attempt to solve them is the result of time-honored experience.
