Machine Foundations
Design, dimensioning and execution supervision of conventional and spring-mounted machine foundations of all kinds. From small devices (PCs) to large machines (turbine generators), both for new installations and for conversions/upgrades.
Engineering
We are proud to offer the whole spectrum of engineering services for machine foundations / elastic supports: consulting, planning, static and dynamic analysis, project and execution drawings, detailed construction manuals, construction supervision and measurements; these apply not only to new constructions but also to extensions, reconstructions, and corrective maintenance, and they are offered in the corresponding country-specific requirements / provisions (language, codes).
Dimensioning, Design Criteria
The requirements of the foundation can be outlined to ensure a smooth operating under normal condition and to retain its structural integrity under various accidental conditions. Dynamic considerations are an absolute must: analysis of natural vibration (must be situated out of the operating speed), of vibration due to unbalance and of transient vibration (i.e. short circuit). Further governing aspects: the rigidity must maintain the shaft alignment, the vibration isolation must be provided in both ways (source and recipient) and the foundation must resist seismic loadings.
Restructuring, Upgrading
A restoration or modernisation of a machine, mainly to extend its life time or to increase output, affects its foundation as well. To achieve an optimal solution, we investigate with the client how to minimise the structural changes regarding time of construction and costs based on coupling our longterm experience, advanced calculations and current knowledge. The best results have been obtained by using / changing to a spring mounted foundation. We provide all the engineering services from one source.
Vibration Isolation
Besides the conventional execution, machine foundations are also often supported by a system of springs to achieve vibration isolation (spring mounted foundation). We are specialists and carefully follow the latest developments in this area. Two different categories have to be separated: source isolation of machines and installations (e.g. elastic support of turbines, condensers, feed pumps, sledge hammer and presses) and receiver isolation as protection for delicate machines and installations, against all kind of vibrations including earthquakes.
Spring Elements
Trombik Engineers Ltd. produces a complete range of high accuracy spring supports for high and highest loads. These height-adjustable TROMBIK Springelements have been enhanced and optimised based on long lasting experience and can be applied to all load areas and purposes. For the main part, built up of disc springs, as well for the casing parts, materials of the highest quality class are used. Special designs for clients and/or for objects, e.g. helical spring layouts or adapted load areas are possible as well.
