Is the pump controlled to start and stop from a control room?
Thread Content
As the title suggests, are there any standards that set requirements in this regard?
It’s completely possible, as long as the interlock protection systems are properly in place. Nowadays, all the moving equipment in power plants requires to be started with a single button press from the control room; it’s likely that this will also be the trend in the chemical industry in the future.
Indeed, pumps and valves used in processes such as desulfurization in power plants are now started and stopped from the control room; the standards should be set by the manufacturers themselves. Of course, it is desired that the equipment require no maintenance, and personnel will conduct inspections in the workshop during each shift.
It also depends on where the pump will be used; it’s necessary to determine whether centralized control for starting and stopping is required based on the actual circumstances
According to the process requirements, the prerequisite is that the pump motor must be capable of starting automatically. The control room can be used to start and stop pumps
Generally, the pump can be stopped in the control room; starting the pump is usually not done, as on-site verification is required before starting it.
Before starting the pump, it should be checked; starting or stopping it from the control room is also possible.
Generally, no start/stop mechanism is provided; it will start when someone goes to the site to close the outlet valve. If DCS control for starting and stopping is necessary, it is best to install a shut-off valve at the outlet, or equip the pump with variable frequency control to enable starting at a low frequency
It is possible to control the start and stop of the control room in all cases, but the specific procedure depends on the size of the motor; low-voltage motors work fine for this purpose, while for medium- and high-voltage motors, it is better to have someone on site to control the start and stop of the pumps, as this ensures greater safety by allowing for proper monitoring of the situation.
Those with high intelligence requirements can be controlled via the central control system; it’s best to also have an operation console on site~~
