Stainless steel pumps are commonly used in various industrial applications. However, with long-term use, they may experience scale buildup, which can significantly affect performance. To ensure normal operation, it’s essential to take proactive measures to prevent and mitigate scaling.
1. Control the Hardness of Circulating Cooling Water
The operation of circulating water in stainless steel pumps is similar to that in low-pressure hot water boilers.
Managing water quality based on boiler water standards can effectively prevent scaling and corrosion in the pump.
2. Maintain Proper Water Temperature in the Circulating System
The temperature difference between the water inside the pump and the soft water tank is a key factor contributing to scale formation.
Increasing the supply of circulating water improves cooling and slows the rate of scaling.
To manage this:
- Monitor the return temperature and flow rate of each pump.
- Use valves to adjust water supply.
- If the return water temperature is too high, supplement with low-temperature water or apply additional cooling methods to reduce the soft water tank’s temperature.
3. Perform Regular Internal Rinsing
The pump’s drain valve is not only used to discharge residual water but also to periodically flush the pump interior using internal pressure.
This removes dirt and water sediments, preventing them from turning into scale over time.
By understanding the usage conditions of your stainless steel pumps and addressing potential scaling promptly through maintenance and system optimization, you can extend the equipment’s service life and ensure efficient operation.
