Why does a high-power high head water pump over 3.7kW easily damage the impeller and pipeline upon direct startup, and what is the remedy?
Because a large-capacity motor when started directly will reach maximum speed in just a few seconds, creating a sudden surging water pressure that shocks the impeller and pipe walls. To handle this, the system must use a Star-Delta starter electrical panel to let the machine accelerate gradually, or optimally, install a Soft Starter / Variable Frequency Drive to ensure a smooth water flow, protecting the pipelines and mechanical impellers.
Why must the discharge pipe valve of this high-capacity high head water pump never be completely closed for more than 2 – 3 minutes during operation?
When the discharge valve is tightly closed while the motor is still running strongly, all mechanical energy of the impeller turns into thermal energy since water cannot escape and instead swirls around the volute. The water inside the pump chamber will boil very quickly, deforming the impeller, destroying the mechanical water seal (causing water leakage into the motor), and potentially cracking the cast iron casing of the pump head due to thermal pressure.
When installing a horizontal end-suction centrifugal high head water pump, why must an eccentric reducer be used on the suction pipe connected to the pump inlet?
If a concentric reducer is used, the upper edge of the pipe will create a space that traps air pockets, which cannot escape when priming the pump. When these air pockets enter the impeller chamber, they cause cavitation, making the pump vibrate, roar noisily, and drop its discharge pressure. Using an eccentric reducer with the flat surface on top allows air to completely escape through the discharge port, ensuring the suction pipe remains fully filled with water.
