Product description

Piston water hammer absorber is a device used to eliminate water hammer shock waves caused by various reasons in pipelines and protect pipelines and equipment from damage. It is suitable for various water supply and drainage systems such as industrial and mining, enterprises, high-rise buildings, power stations, etc. The expansion and contraction of the air in the upper chamber of the piston is used to buffer the sudden shock wave and relieve the intensity, and avoid the huge water hammer to the greatest extent. Equipment damage caused by impulse. The device has simple structure, excellent material selection and long service life.

Working principle

The piston-type water hammer eliminator has a closed air chamber inside and a piston at the lower end. When the shock wave is transmitted into the water hammer eliminator, the water hammer wave acts on the piston, and the piston will move in the direction of the air chamber. The stroke of the piston movement is related to the gas pressure in the air chamber and the size of the water hammer wave. Under the dual action of a certain pressure of gas and irregular water hammer, the piston moves up and down to form a dynamic balance, which effectively eliminates Irregular water shock waves oscillate.
