Large and special fans are often exposed to the harshest wear attacks. Abrasive media that are carried in the air flow (e. g. clinker dust, quartz and also corundum, wood and plastic shavings) assault the material.
Wear can render high-quality machine parts inoperative in the shortest time. The resulting costs are considerable. Invest in preventive measures is economical.
Venti Oelde uses various measures to prevent abrasion to impellers and inner casing walls through friction and impact wear. Such protective measures are decided on as early as during the design of our fans. Suitable materials, high-precision machining and optimal blade geometry effectively increase service life.
Venti Oelde has verified the specific properties of the various materials and combinations through many series of tests. Precise knowledge of the process conditions allows us to select the most suitable measures for each application and load intensity. Examples of materials used are surface-hardened steels and steel alloys containing manganese and also composite materials that are sintered at high temperature.
The optimized geometry of our impellers guards against caking. The shape of our inlet-boxes, impellers and volute casings are so designed that wear and caking is minimized.
Hardfacing is ideal for fending off extensive wear attacks. Replaceable wear spirals, wear plates and deflecting plates are versatile in their application. With particularly abrasive media, surfaces are protected by hardfacing using tungsten or chromium carbide, whereby the service life of the components is many times increased. Lining by armouring is one of our quality features.
We can naturally hardface or reface impellers when repairs are carried out.
Venti Oelde utilizes water and compressed air injection and acoustic systems to detach sticky, adhering media. In special cases, the targeted addition of coarse, abrasive substances can allow a self-cleaning effect to be obtained.
Finally, our electronic monitoring systems reliably work for preventive maintenance and service at proven profitability. Installed vibration monitors control the oscillation amplitude and give early warning of dreaded material caking in the fan. Our dynamic balancing systems reduce any imbalance and vibrations by mass compensation.
