CONSTRUCTION TYPE
The vacuum system SIHIdryM100 is based upon the dry running twin screw principle. The screw-shaped displacing bodies counter-rotate without contact. The pump inlet is at the top and the outlet at the geodetically lowest position (top-down pumping).
In contrast to conventional pumps the both screw spindles are not mechanically but electronically synchronized. This innovative drive conception is the basis for a stepwise development of the vacuum pump to an intelligent vacuum system which takes on additional functions as the valve-, and pressure control for example. Furthermore the intelligent system offers the possibility to exactly monitor the important process data in order to ensure a maximum of process safety.
DESIGN
The vacuum system SIHIdryM100 has been developed for the use in areas with and without explosion hazard.
The flexibility of the modular system allows its adaptation to any process according to the attached selection table.
The cooling water circuit which contains a casing shell allows the adjustment of the surface and gas temperatures. The drive control system protects the mechanical components as well as the motors against overload. Under extremely difficult operating conditions as e.g. backwater surge the system automatically reduces its speed so that any damages are avoided.
