A GUIDE FOR SYSTEM DESIGNERS
The presence of uncontrolled quantities of air in water systems can seriously affect their performance, causing inefficient filling and draining procedures and flow reduction, while increasing energy costs. It also disrupts the operation of some of
the system’s components.
In a recent BERMAD webinar, “How to Design & Implement a Pressure Reducing Station for Extreme Pressure Difference,” Micha Baer, our Waterworks Application Engineer, talked about the challenges in dealing with extreme high pressure in a water supply pipeline.
In a recent BERMAD webinar, “Smart Metering with Electromagnetic Flow Meters,” our Smart Metering Product Manager Elad Orenstein talked about the benefits of using electromagnetic flow meters to collect accurate data and make it available anywhere, at any time.
In a recent BERMAD webinar, “Optimal Air Valve Selection for Water Systems,” our application engineer Tal Levi presented tools to optimize the selection of air valves, parameters affecting performance, and premature kinetic closure.
In a previous blog post, we described how as a result of rising awareness about energy savings and environment protection, water supply and distribution systems need to be more efficient and be able to operate optimally at minimum pressures. While single-chamber control valves were traditionally used in these systems due to their cost-efficiency, their functionality is limited in such low pressure conditions.
Since the turn of the last century, hydraulic control valves that utilize line pressure as the energy source for their operation have been used in water supply systems. These valves are used for specific control functions that include pressure and flow control, water level control in tanks and reservoirs, remote open and close, and more.
Water hammer, or hydraulic shock, is a major concern in bulk water supply systems. It is even more of an issue when dealing with high pressure systems where failure may have a catastrophic impact. It is caused when fluid moving through the system is forced to suddenly stop or change direction, creating a pressure wave that can create vibration and noise, damage pumps and other system components, and even collapse pipes.
What’s the connection between control valves and smooth take-offs and landings at Berlin Brandenburg Airport?
The Berlin Brandenburg Airport is a 14.7 km2 airport that is situated 18 km south of Berlin, Germany, and is currently under construction. The 6.8-billion-euro project began in 2006 and includes two parallel runways, a six-floor passenger terminal, a 32-meter observation tower, and a museum and gift shop. The facility is designed to handle about 65 aircrafts, with a passenger capacity of up to 27 million per year. The airport is expected to open in autumn 2020.
