Help needed； Is it necessary to turn on the cooling water when the centrifugal pump is in operation?
Thread Content
Is it necessary to use cooling water to cool the bearing end seals of a centrifugal pump that operates over a long period of time? (The medium transported is liquefied gas.) If no cooling water is used, is there a risk of damage to the end seals or leaks occurring?
Before starting any equipment, it is necessary to check the transmission system, lubrication system, cooling system, interlock system, and so on. Even a small centrifugal pump is still considered an equipment unit; how can it be started without cooling water? Over time, the temperature of the bearings will rise
Our liquefied gas pump doesn’t have cooling water.
Some centrifugal pumps have an organic seal cooling system, while others do not; if a cooling system is present, it must operate simultaneously.
The mechanical seal or bearings are equipped with a cooling system, which is activated in advance when the pump is started.
If there is cooling water, cooling is definitely necessary; otherwise, it’s difficult to dissipate the heat generated during the operation of the bearings. Generally, the operating temperature of rolling bearings should not exceed 75 degrees. To monitor the condition of the bearings, one should listen for noises, feel for vibrations, and check the temperature. Only by keeping an eye on the performance of the bearings and sealings can we ensure better maintenance of the pump
Everything set is reasonable, with nothing redundant; it should be put into use.
Before starting the moving equipment, it is necessary to check the electricity, water, and other related facilities.
Needless to say, it runs if it’s available, and it doesn’t run if it’s not.
If there is one, it needs to be turned on; this is specified in the equipment’s user manual
I would like to ask everyone: do pumps generally have a cooling system? Isn’t heat carried away by the fluid?
