What is the function of the chiller valve in the low-temperature methanol washing centrifugal pump?
Thread Content
All the centrifugal pumps in the low-temperature methanol washing cooling section are equipped with a chiller valve. What is the function of this chiller valve? I would appreciate it if experts in this field could provide an answer. Thank you.
Cold pump line: This valve is kept at a certain opening level to ensure that the temperature of the standby pump is as close as possible to that of the operating pump. This helps to reduce the damage caused by thermal contraction to the pump itself when the standby pump starts up. Be careful not to open it too much to prevent the standby pump from rotating in the reverse direction.
Cool the standby pump to ensure it can start up quickly while in a cooled state!
Cool the standby pump so that its temperature is close to or equal to the temperature of the medium being transported, thereby preventing cold medium from entering the pump and causing uneven thermal stress
The cooling pump ensures that the pump can be started quickly in case of any problems, thus maintaining stable system operation; it also allows for the temporary use of two pumps to ensure production continues
