The TEV Jäger development philosophy
TEV Jäger always develops its rotor nozzles with the aim of achieving the lowest energy loss and the highest cleaning and removal performance, while at the same time ensuring a uniform cleaning result. This philosophy applies both to the use of rotor nozzles in manual cleaning processes and in automated systems.
Through ongoing research and development, TEV Jäger utilises innovative technologies and materials to continuously improve the efficiency and performance of the rotor nozzles. This includes optimising flow dynamics, material selection and design details in order to minimise energy loss while achieving maximum cleaning efficiency.
TEV Jäger's rotor nozzles are designed to deliver a powerful and precise cleaning action, whether they are used manually or integrated into automated cleaning systems. This ensures that customers in various applications can benefit from an efficient and reliable cleaning solution that fulfils the highest standards in terms of performance and quality.
TEV Jäger has state-of-the-art test benches available for development. These test benches are specially designed to determine all relevant parameters and enable rotor nozzles to be developed to a very high level of quality.
The test benches are equipped with advanced measurement technology that enables a wide range of rotor nozzle performance characteristics to be accurately recorded. These include pressure, flow rate, rotation speed, cleaning effect and removal rate. By precisely analysing these parameters, engineers at TEV Jäger can optimise the performance of the rotor nozzles and ensure that they meet the highest quality standards.
By utilising these state-of-the-art test rigs, TEV Jäger can ensure that their rotor nozzles meet customer requirements in terms of efficiency, reliability and durability. This enables them to offer innovative and high-quality cleaning solutions that meet the requirements of a wide range of applications.
The mechanics behind rotor nozzles
A rotor nozzle is made up of various components: a pressure housing, a drive plug, a rotor and a bearing unit. Its purpose is to generate a focused jet of high-pressure water that rotates around an axial centre point. This enables extremely effective cleaning of a wide variety of surfaces.
The way a rotor nozzle works is impressive and can be explained in several steps. Firstly, the high-pressure water is fed into the drive plug through a feed line (high-pressure lance). This water then emerges from the axially drilled holes in the drive plug and fills the pressurised housing. The high speed at which the high-pressure water fills the thrust housing pushes the rotor into the bearing unit and seals it against water leakage. Now the high-pressure water can only escape from the housing via the rotor, creating a pressurised water flow.
As the water enters axially through the holes in the plunger, the water flow creates a rotating field that entrains the rotor. The centrifugal force acting on the rotor in the rotating field presses it against the pressure housing, causing the rotor to complete a guided circular path.
Finally, this circular path is transferred to the spot jet, which is generated by the water outlet via the rotor. This creates the rotating spot jet, which can be used extremely effectively for cleaning.
The pressure range in which our rotor nozzle operates is between 130 and 2500 bar, which gives it a wide range of possible applications.
The variety of rotor nozzles in their design
A rotor nozzle uses a variety of materials that are specially designed for their function and durability. Typically, materials such as ceramic, carbide, brass, stainless steel and high-tech plastics are used.
Ceramic: Due to their excellent wear resistance and chemical resistance, ceramic components are often used in rotor nozzles. They enable a long service life and high performance, even in demanding environments.
Cemented carbide: Carbides, also known as tungsten carbide, are often used for nozzles as they are extremely hard and wear-resistant. They are particularly suitable for contact with abrasive media and help to improve the overall performance of the rotor nozzle.
Brass: Brass is often used for housings and certain parts of the rotor nozzle. It provides good corrosion resistance and mechanical strength and helps to stabilise the structure of the rotor nozzle.
Stainless steel: Stainless steel components are often used in rotor nozzles for their corrosion resistance and ability to withstand extreme pressures and temperatures. They are ideal for use in various environments, including aggressive chemicals and high temperatures.
High-tech plastics: Advanced plastics developed specifically for their durability and chemical resistance are also used in rotor nozzles. These materials offer excellent performance and are often lighter than metallic alternatives, resulting in improved handling and efficiency.
