Anti Vibration Products
AVM Diesel can supply anti vibration products for the marine and industrial applications as well in bridge construction, in road and rail vehicles, in electronics, indeed wherever noise and vibrations are generated. Our products used the latest up-to-date equipment in the manufacturing process from the Laboratory, Test and Experiment and Metrology to the Production equipment.
Throughout the manufacturing process of the products, intermediate inspection and evaluation are carried to ensure that the highest quality is achieved. Therefore we are able to advise the customers on noise and vibration insulation problems and provide the right expertise for an optimum solutions to special and complex problems.
<p style="text-align:justify;">AVM anti-vibration mounts are the preferred choice when it comes to the vibration and sound insulated bedding for engines, blasts, tool machine, printing and textile machinery. They have a favourable thrust-spring-constant/pressure-spring-constant ratio. Because of the higher degree of horizontal stiffness their mechanical movements can be largely compensated. All these products are maintenance-free. The manufacturing of these machine feet is done on the basis of natural rubber.</p> <p></p>
<p style="text-align:justify;">Many engines are equipped with one or two Hasse & Wrede viscous shear type torsional vibration damper attached to the forward or non-flywheel end of the crankshaft. The purpose of this vibration damper is to minimise the influence of the torsional vibrations developing in the crankshaft, so that the material stresses arising from these conditions are kept within permissible limits.</p> <p style="text-align:justify;">A damper which is in poor condition or which is not operating will increase the torsional vibration, resulting in an increase in material stresses and can lead to undue strain on the crankshaft and transmission components.</p> <p style="text-align:justify;">The lifetime of a damper, among others, depends on its thermal load and on the running conditions. From experience we know however that the effective operation of the damper may reduce after some period.</p> <p style="text-align:justify;">When a damper requires overhaul, it must be completely dismantled to enable removal of contaminated fluid, possible machining of any internal mechanical damage and modification to current specification. All dampers are leak/volume check by vacuum filling rigs to ensure correct service volume is achieved. Therefore, dampers cannot be overhauled in-situ and must be removed and returned to our factory.</p> <p></p>
