Hydraulic Hammer Effect
Definition - What does Hydraulic Hammer Effect mean?
Hydraulic Hammer Effect is an intense sudden pressure surge experienced by hydraulically working equipment. The hammer effect is also known as water hammer and generally occurs in the pumping system that experiences abrupt change in fluid flow during high pressure conditions. In such situations, pumps start and stop creating back pressure and dangerous shock waves that are transferred back and forth.
Petropedia explains Hydraulic Hammer Effect
Hydraulic hammer effect is one of the common observed phenomenons which take place in pipelines during fluid flow. In order to notice the hammer effect, the banging noise or thumping noise is recognized. The hydraulic hammer effect affects the oil and gas industrial equipment such as flow meters that are installed on the steam network. Hammer effect is one of the safety issues that have to be seriously considered. When there is sudden pressure surge because of sudden stop of moving fluid or direction change (momentum change), the high amount of force is exerted on the equipment walls causing the hydraulic hammer effect.
