General description of Rotary PD Bolwers
Rotary blowers basically comprise a stator housing two symmetrical pistons with three-tooth gearing, which rotate in opposite directions at a uniform speed.
A helical gearing torque with rectified sides constantly ensures the correct distance between pistons, likewise guaranteeing the strict assembly tolerances that are so important to good mechanical operation and high volumetric performance. The fluid to be conveyed penetrates the chamber formed by the stator and the pistons, the rotation of which set the compression filter in motion. The end pressure of this operation depends upon the friction slip in the fluid pipes and the specific utilization performances.
The volumetric performance of the blowers is constant, allowing for operation with variable pressure regimes. Six unitary sectional volumes suction and compress with every full turn of the drive shaft. Constant pressure and increased blower speed will proportionally increase the exhaust flow rate. Absorbed power automatically adjusts to real working time, thus avoiding unnecessary energy consumption.
The absence of friction between the pistons makes lubrication unnecessary in the compression chambers, meaning that the air in- put is totally OIL-FREE.
This is one of these blowers’ main advantages and is an extremely valuable characteristic with respect to chemical processes and applications requiring a very low level of contamination.
Volume flow up to 22,400 m3/h. Pressure rise up to 1 bar and vacuum limit up to 500 mbar.
Low Noise and Pulsations:
The new generation of blowers with trilobular pistons and a specifically configured housing impulsion filter offers considerable reduction in the initial pulsating effect and hence progressive compression.
The basic concept of this new design moreover generates a frequency increase, thus reducing oscillation and optimizing the efficacy of the exhaust silencer-frame.
Our wide range of blowers means that we can offer an oil-free fluid, which is now virtually obligatory with respect to the increasingly varied applications of industry in general and ecology in particular. Preserving the environment requires the taking of steps to control, conserve and prevent causing harm to nature, and the using of technically reliable and economically viable means in order to do so.
Our blowers form an integral part of the several existing methods of environmental regeneration, and contribute by means of pressurized air to the carrying out of a number of processes.
