Sometimes known as water hammer, excessive surges in pumped liquid systems are undesirable. If uncontrolled, it can lead to catastrophic system failures, such as pipe breakage, and valve and pump damage, resulting in downtime and high consequential loss.
Surge conditions may occur for various reasons, typically - but not limited to - normal pump start/stop sequences, pump failure, power supply failure and general control and valve failure within the liquid conduits.
The result of a major liquid flow valve being opened or closed, or a rapidly changing demand, may also have serious effects on the pipeline integrity.
At the early stages of a pumping system design, a hydraulic study/analysis should be carried out. This will highlight any potential surge condition that may occur in the proposed pumping regime.
Once the system characteristics are finalised and surge control methods have been highlighted as being required, Quantum Engineering Developments expertise may be sought to detail, manufacture, install and commission surge control equipment to alleviate any potential pumping system failure.
All surge control systems are tailored to suit the pumping system characteristics and are therefore unique to each scenario.
The company has various methods of control to damp surges in all major liquid systems, whether potable water, raw water or sewage. The control method is also selected to suit each particular pumping regime, which may have fixed or variable flow rates.
