Roll dip impregnation machines
The “Roll Dip” impregnation method, known in the US market as “Roll Through”, is suitable for both rotor and stator winding.
In the Roll Dip impregnation station, the system is equipped with one or more thermostatic cups containing resin and/or varnish to be used in the process; the resin is constantly flowing and overflowing to-from the cups through specific pumps. When the component is presents in the Roll Dip impregnation station , the cups automatically rises on the rotating stator/rotor and it can be partially dipped up to the specific level .
The component constantly rotates, during both the Roll Dip and the gelation phase, so the liquid product (resin) applied penetrates evenly and fully in the component windings (slots and heads), getting high levels of solids content after polymerization. Such impregnation method ensures high bond-strength levels on the winding and is particularly suggested and used for all products where thermodynamic stresses are relevant and strong in their service .
Detail of a rotating stator in the Roll Dip impregnation area The TF ROLL DIP series is designed to combine user friendliness, flexibility and environmental friendly. All components were chosen for their reliability and safety.
The technology used in our Roll Dip systems complies with the best quality, reliability and automation standards. These features result in several advantages by the Roll Dip impregnation method : High quality impregnation Maximum resin filling on the winding slots All impregnation parameters are controlled by PLC. If different products undergo the impregnation process (“Random” production mode), you can set the following specific parameters for each single component; Component rotation speed Our TF ROLL DIP systems are designed and realised in order to use Traditional polyester , No-Solvent Polyester , Epoxy and Epoxy-Phenolic Resins, and all other medium-high performance products suitable for this impregnation method. The operator can easily change process data in order to comply with the product manufacturer’s instructions. |
