Vacuum Container – Container for Impregnation
Several components must be impregnated with special oil before they are used for example in transformers.
To ensure that this oil can penetrate better, it is necessary to exhaust the air from the open pores of the components. These parts are introduced in a corresponding vacuum chamber. After a short hold time a valve opens and Impregnating Oil flows from the storage container to the vacuum container until the batch is completely covered. The oil can now move into the finest pores of the components.
Typically, vacuum tanks are manufactured in cylindrical form to be able to compensate the forces, resulting from the negative pressure. The dimensions of the components, and their use in some cases, however, require different container shapes.
In the case shown, a rectangular container (LXBXH 2.3 x 0.93 x 0.8 m) should be constructed. With the help of modern methods of calculation we have designed an appropriate container, which, with minimal use of materials and meaningful arranged stiffeners, has a maximum of stability. A circular groove at the upper vessel flange with an inserted round cord ring ensures a reliable seal of the cover.
The massive executed cover, supported with 2 gas springs, can be opened and closed manually. In the case shown, the opening is via a small winch.
All connections, for example for the vacuum pump, the inflow and discharge, are already provided or can be made to meet specific customer requirements. The containers are made of stainless steel.
