Recently, leway 100m³ water hammer elimination tank was successfully shipped, the tank is used for the Hebi section of the south-to-north water diversion project!

The water hammer eliminates the effect of the tank

In the pressure water supply pipe, due to some external reasons (such as the valve suddenly closed, the pump unit suddenly stopped) the water flow in the pipeline in the action under the action of inertia on the action of the valve or equipment rapidly large, and produce damage effect, this hydraulic phenomenon is called water shock or water hammer. Water hammer elimination tank by absorbing the water in the water supply pipeline and filling water into the pipeline system, effectively weaken the water in the transmission system water hammer and surge and other irregular water strike wave shock, thus reducing the shock wave damage to valves and equipment,play the purpose of protection.

Operational principle

Step.1 Based on the data analysis to eliminate the pre-filled pressure in the tank. At this point, the water hammer eliminates the sac of the tank. When

Step.2 opens the gate valve, the water will enter the water capsule of the tank under the pipe pressure and begin to compress the air between the tank and the tank. The water from

Step.3 into the capsule gradually presses the prefilled gas until the water hammer removes the balance between the tank pressure and the pipe pressure.

Step.4 Once the pump trip occurs, the pressure in the pipeline will immediately drop, and the water hammer elimination tank will use its own pressure to discharge the water from the bag into the pipeline, thus effectively preventing the negative pressure in the pipeline.

Step.5 Since the pressure may become very low, the current will move in reverse, and several oscillations may occur before entering the water hammer through the bypass valve, etc.

Step.6 When the pump restarted, the water hammer protector will continue to store water until the system pressure balance is reached and prepare for the next pump start and stop again.
