Bornemann thread technology on the IFAT trade fair in Munich on the world’s leading trade fair for water, sewage, waste, and waste management has become the strategy of focusing on niche markets again for the Delligser company paid out. Already our customers we include many well-known German and European manufacturers in this area and of course pleased that the special quality of our special thread further prevails in this demanding sector”, says Moritz von Soden, sales manager at Bornemann thread technology. The steel-water construction demands a special threaded spindles for drives and includes areas of steel construction and mechanical engineering from the statics, the hydrostatic, hydrodynamics, the mechanics and material science using calculation methods. Especially moving lock constructions for lockable openings such as basic indulgences of dams, weirs, barrage locks, doors locks and docks are made by the manufacturers in this field. The operation on the waterways depends on the lock structures and their reliable drives as well as the drainage of land lines or the regulation of watercourses. In particular the establishment of flood retention basins and water turbines have gained in importance as a result of climate change and energy transition in recent years. Fortifications and in addition often find themselves in control of flood channels, sea water and irrigation systems they are building essential for the use of water power.
Site specificity and terms decide about their type of construction and hence the drive of moving parts. Enormous water pressures sometimes weigh on the closures, which have to be transported through the threaded spindles. Some of the structures are crucial here long-term reliability, but others like particularly Weirs and basic indulgences, while once in a year or more rarely moved several times a day. The complete or partial contact with water represents another challenge and requires the Use of special steels in the threaded spindles. In particular, formerly practiced use of steel has proved not feasible.
