The rotoválvulas Torex distinguish by his compact design and a robust construction. The series RV divides in four basic models: RV2, RV5, RV10 and RV20. In them, the numbers indicate the step of litres by revolution of the rotor and his discharges, that arrive to 28 m3/h with a degree of filled of 80%. The steps of entrance and exit oscillate between the model 150 and 300 millimetres.
In some occasions, by the bad use or unsuitable applications, produce immobilisations of the rotor by part of the product. To avoid this phenomenon, the rotoválvulas Torex have together fluidificadas that, by means of the supply of air (interval advised 0,2-0,4 bar), realises a preventive cleaning, deleting of this forms zones of cumulus of material and possible risks for the team.
In relation to the durability of the rotoválvula, exerts a very important paper know the DNA of the product to treat, since in function of his properties and behaviour, will determine the material of the body, as well as the palettes, the presses estopas and the inclusion of bibs or scrapers to avoid the learning of layers of product in the internal walls of the team.
In relation to the control of the rotoválvula can realise through a signpost of control totally centralised or through a variator of frequency installed in the alveolar that allows the control of twist. In the series RVC, unlike the series RV, is the predisposition in the inferior part with tight boards to avoid escapes of air to his time the user realises a canalisation that conexiona with the pipes of the pneumatics installation.
Also in this case are four basic models, that correspond to the different discharges to choose (RVS/C10, RVS/C15, RVS/C35 and RVS/C20). The performance depends of the half where install and of the speed of corresponding rotation.
The main profits that contribute the rotoválvulas Torex summary in:
The efflorescences, so much primary like secondary, are a common problem for the manufacturers of prefabricated of concrete. They produce when the hydroxide of calcium and the hydroxide of present sodium in the concrete go in in contact with water and air... [+]
