Water Tank Swirl Preventer, also known as water tank swirl eliminator, hydraulic vortex preventer, high-efficiency cyclone preventer, fire water tank cyclone preventer, stainless steel structure cyclone preventer, is a special pipe fitting used to prevent water tanks (pools) from generating vortices during liquid transportation and to prevent air from entering the pipeline. Its function is to be installed on the suction pipe port of the water pump in the water tank (pool), to eliminate the vortex inside the water tank (pool), to ensure that the water pump can start and work normally with full force, to avoid air entering the water pump and causing cavitation, and to lower the liquid level of the liquid transported in the water tank (pool) to a lower level, to ensure maximum flow delivery.
In the fire water system, the application of swirl preventers is particularly important because swirl can cause a pressure drop in the fire pipe network, affecting the normal use of fire protection facilities. When the fire water pump draws water from the fire water tank, if there is no suction well at the suction port, a swirl preventer should be installed at the suction port to increase the effective water storage capacity of the fire water tank.Cyclone preventer is suitable for fields such as chemical, energy, and water engineering, especially for use in fire water intake tanks (boxes). It can ensure that the effective volume is fully utilized, improve the effective utilization rate of fire water tanks, reduce stagnant water areas, and achieve land saving requirements. During rescue operations, fire water can be used to the maximum extent possible.
Supporting valves: In fire water supply systems, swirl arresters are often used in conjunction with check valve, gate valve, or butterfly valve to ensure the safe and efficient operation of the system. For example, check valves can prevent water backflow, while gate valves or butterfly valves are used to control the water flow in the system
Installation requirements: The installation of the swirl preventer should consider the distance from the pool wall, and it is usually recommended to leave a gap of not less than 0.3 times the nominal size of the suction pipe to ensure the effectiveness of the swirl preventer
