Water hammer tank is also known as water hammer elimination tank, inner tank water hammer elimination tank, airbag air tank, inner tank air tank, inner tank water hammer safety protection tank, inner gallbladder waterproof hammer tank, etc.
What equipment is an inner tank water hammer tank? What are the functions?
The inner tank water hammer tank can be said to be a water storage vessel, which will be assembled in various pipelines to reduce the pressure caused by the change in total liquid flow rate in the pipeline. When the connecting valve is opened, water enters the tank while reducing the volume of air in the tank until the working pressure in the tank reaches equilibrium with the pipeline pressure. When a pump stop water hammer occurs, the water stored in the butyl tank is quickly introduced into the pipeline under the influence of butyl elasticity to prevent air pressure from being generated inside the pipeline. In the second stage of water hammer, when water flows back in the pipeline, the inner tank water hammer elimination tank absorbs water from the pipeline under the buffer of standard air pressure and the elasticity of the butyl inner tank, and digests and absorbs the energy of the backflow water flow in the pipeline, avoiding the impact of backflow water flow on the pipeline or check valve, which can cause the instantaneous working pressure in the pipeline to jump to an accident working condition.
Automatic defense system for water hammer tank
It is the structure of a column type inner tank water hammer elimination tank, and the more basic structure is to add plastic airbags to the storage tank. Based on customer satisfaction, an automatic water hammer defense system can also be equipped with magnetic level gauges, water level sensors, temperature transmitters, valves, air compressors or nitrogen cylinder groups, control boxes, and distribution boxes, which can provide services such as automatic air filling and discharging, cloud space reporting, and real-time monitoring.
Where is the inner tank water hammer tank used? Where is a better place to assemble?
The inner tank water hammer tank is mainly used in long-distance water pipelines, including domestic water plants, sewage and wastewater treatment plants, seawater desalination plants, power plants, petroleum pipelines, water diversion projects, agricultural irrigation projects, river embankment water replenishment and moisture retention industries. The inner tank type water hammer elimination tank is installed on the outlet side of the centrifugal water pump at the drinking water source.
What material is used for the inner bladder of the inner water hammer tank? What are the advantages of these materials?
The airbag material in the water hammer elimination tank is generally made of butyl chloride. Due to its waterproof hammer performance and longer service life compared to other materials, butyl has certain advantages in the inner liner. It is not recommended to use natural rubber and EPDM rubber. Natural rubber and EPDM rubber have poor sealing performance, and their service life and characteristics are far inferior to butyl rubber.
What are the manufacturing standards for inner tank water hammer tanks?
The inner tank water hammer tank belongs to high-pressure vessels. Different countries or regions have different design schemes, production and production standards. It is mainly divided into the following three standards:
1》 Chinese regulations: Implement the national standard GB150-2011 Pressure Vessel Standard Technical Standard according to TSG-21-2016 Mobile Pressure Vessel Safety Technical Supervision Technical Specification.
2》 EU regulations: Implement the PED2014/68/EU standard for high-pressure vessels, and the standard specifications implement EN13831:2007
3》 Countries such as the United States, Canada, and the Middle East: follow ASME standards for implementation.
