ZYA-9000 piston absorb water hammer Overview ZYA-9000 piston absorb water hammer, the device structure is simple, excellent selection, and long service life. Piston absorb water hammer is used to eliminate the pipeline due to a variety of causes water hammer shock protection device pipelines and equipment from damage. For industrial and mining enterprises, high-rise buildings, power plants and other types of water supply and drainage systems, the use of the upper chamber of the piston in the expansion and contraction of the air, so that the shock wave bursts are buffered and eased efforts to maximize the enormous avoid water hammer Equipment damage caused by momentum. Absorb water hammer piston of the device structure is simple, excellent selection, and long service life.
