The oil slinger HZB253-640-01-05 is a component installed in the boiler front pump. Through a special structural design, it allows lubricating oil to be effectively "thrown back" into the pump box when the pump shaft rotates, rather than flowing along the side of the pump shaft. This can maintain a stable amount of oil inside the pump box, while reducing the wear of oil seals and other sealing components, and improving the efficiency of the entire lubrication system.
The special feature of the oil slinger HZB253-640-01-05 used on the boiler front pump is that it needs to adapt to the requirements of high temperature, high pressure, and corrosive environments in the boiler system. The boiler front pump is usually used to pump water or other working fluids from the boiler to a high or distant location to maintain the normal operation of the boiler.
When selecting thrust bearings for multi-stage centrifugal feedwater pumps, the following factors need to be considered:
1. Working conditions of the pump: including medium type, temperature, pressure, flow rate, etc.
2. Axial load: Select the appropriate thrust bearing based on the axial load of the pump.
3. Reliability of bearings: Ensure that bearings have high reliability and stability during long-term operation.
4. Maintenance convenience: Choose bearings that are easy to add oil, inspect, and replace to reduce pump maintenance costs.
5. Economy: On the premise of meeting the working requirements of the pump, choose bearings with high cost-effectiveness.
