Cooling flush for shielded pumps
Thread Content
I would like to ask what the red part in the image is and what its function is How does the self-cleaning of the yellow area exchange heat with the circulating water?
The red part should be the exhaust system; as for the cooling system, you can search on Baidu for diagrams of shielded pump structures.
The red part is for exhaust, while the yellow part is used for cooling the pump body and motor
What kind of exhaust is it? Is it for venting?
When starting the pump, exhaust will occur from the red area you marked earlier; once the liquid starts to flow continuously, it can be assumed that there is no gas inside the pump and its operation is normal.
The red section can be considered a type of tee or connector, used to link the heat exchanger (yellow section) with the motor. Filters and exhaust valves can also be installed there; there is an exhaust valve shown in this diagram. Since these pumps are designed for high-temperature applications, they are engineered to include a filling process and an exhaust process, with the purpose of removing gases from the fluid being transported or any air remaining inside the pump. The yellow section is a sleeve – the cooling medium flows on the outside, while the high-temperature medium you want to transport flows inside
Thank you all, I’ve learned a lot! :lol
The red one is used for venting the medium conveyed through the tube inside the sleeve, that is, for venting the pump body； The yellow area is used for cooling the pump body via a sleeve, with cooling water flowing inside the tube.
