in The vibration of concrete The freshly mixed concrete does not compact on its own because the poor fluidity is not able to overcome the internal friction; only vibration can overcome such forces. VIBRATION FAVOURS: • The surfacing of the air trapped in the concrete; • The displacement of aggregates, aligning them to one another, with consequent reduction of cavities, conferring them high density and perfect homogeneity; • The adhesion of the concrete to the bars of the reinforcement armatures or to any internal structural inserts, as well as to the basic anchorages. BENEFITS: • High...

Electric high frequency internal vibrators When constructing industrial floors, walls, columns, sl abs, etc., flexible and easy-to-use vibr ating systems are required. In such cases high-frequency immersion vibrators are generally used, known as “poker” or “spud” or simply “vibrating needles”, which come into direct contact with the concrete; for this reason, we speak of internal direct vibration. The robustness and the constant rotation speed are essential factors in the compaction of the concrete: drops in the centrifugal force heavily reduce the quality of the manufactured article. HOW...

Frequency and voltage converters The internal vibrating needles need to be powered via a three-phase electric line at low voltage, therefore it is necessary to use a voltage and frequency converter. The electromechanical rotary converters consist of a motor and a generator, which are coupled together. The motor converts the electrical energy into mechanical energy; the generator converts the mechanical energy into electrical energy, thus generating the required voltage and frequency (42 Volt - 200 Hz). The converters of the CM range are designed to supply simultaneously and in a continuous...

[n High frequency internal vibrators with built-in converter On construction sites, during the consolidation of the concrete, a light, flexible and easy-to-use tool is often required, which can be connected directly to the common, single-phase power lines (230 or 110 Volt, 50/60 Hz). In order to solve this necessity, the EWO range has been developed: high-frequency immersion vibrators equipped with an integrated electronic frequency converter capable of transforming the single-phase input voltage (230V or 110V, 50/60 Hz) into the three-phase voltage (230 V, 200 Hz) necessary to obtain...

External electric vibrators High frequenc y electric vibr ators are used on construction sites and in precast companies to obtain high-quality products (exposed concrete), with excellent aesthetic results and weather resistance. The vibration is tr ansmit ted to the concrete indirec tly through formworks or mould. High speed vibration (6,000 vmp) is recommended with low-density concretes and in applications where high surface quality is required. Variable frequency allows to find the correct vibration speed in relation to the density of the concrete to be treated. They are obviously more...
