Actual situation of remotely controlling electric pumps from the control room
Thread Content
In the design, there is a mechanism for remotely shutting down the electric pumps from the control room; how is this remote shutdown implemented in the control room? Is it a button on the dashboard, or an option on the computer display that can be stopped by clicking with the mouse? Seeking guidance; would be very grateful if there are pictures
Whether to use a soft button on the monitoring terminal or a hard button on the auxiliary control panel depends on the requirements of your process engineering team. Generally, for ordinary remote control, it can be implemented on the monitoring screen ； If it is related to safety, a physical button can be installed to facilitate manual operation in the event of an accident. The principle is the same in all cases; it is through the opening/closing of the DO card contacts and the intermediate relay contacts that the connection to the power supply circuit for the pump is controlled.
Both methods mentioned by the original poster can be used; it depends on which one you prefer.
The poster can also do both: a stop on-site and a stop remotely.
Thank you so much for your guidance! ! !
Generally, a button is created on the HMI, which might save some money; of course, an emergency stop button can be provided on the control panel for important functions. If the pump is to operate, the design of the pump outlet valve must be taken into consideration.
It depends on the importance of this pump; if it isn’t involved in the process interlocks, a DCS soft switch can be used (one that can be activated by clicking with the mouse)； If this pump is important, install a physical button on the auxiliary control panel and connect it to the DCS card
