Regarding the bearing cooler of centrifugal pumps

Thank you! This pump has a shaft sleeve (I’m not entirely sure if that’s what it is), which is used for the methanol cooling pump. How does it cycle? My master said it cools down on its own. I’m not able to explain it very clearly; I hope you can understand!
There are various circulation methods: 1. The pumping mechanism built into the pump itself, located on the shaft sleeve within the sealed chamber； 2. Auxiliary external circulation power belt monitoring system ； 3. Thermodynamic cycle

In the case of PLAN23, the circulating force comes from the pumping ring of the mechanical seal; in the case of PLAN52, the tank is pressure-free, and the first seal, PLAN11, relies on the pressure difference between the outlet and the mechanical seal chamber to enable circulation. I think vertical cartridge pumps are generally equipped with the PLAN13 scheme, which relies on the pressure difference between the pump inlet and the seal chamber for circulation. What I mentioned above refers to the cooling of mechanical seals; the cooling of bearings is generally achieved through the material itself. Vertical bag pumps use sliding bearings that are submerged in the material.
