Screw chiller

However, these two oil pumps do not have an interlocking mechanism that allows them to start one another; when one oil pump fails, the machine has to be shut down before the other pump can be started, which has a significant impact on production. I would like to ask the experts: Is it possible to set up an interlocking mechanism between these two oil pumps? Is there such a setting?
Interlocks can be set up; it’s better to have interlocks as they result in fewer failures.
A interlock device should be installed; to ensure the stable operation of production, your company’s electrical control department can handle this task.
Contact the instrumentation and control team to set a pressure signal: the two pumps should operate when the pressure is below the set value, and they should stop operating when the pressure exceeds a certain level. Conduct a test to verify the interconnection between the two pumps before starting up the system.
Contact the instrumentation and control team to set a pressure threshold; if the pressure falls below this value, both pumps will operate. The two pumps can serve as backups for each other, and a test to verify their interconnection should be conducted before starting up the system.
