Description
Изобретение относитс к электро-- технике,в частности к технологии изготовлени погружных электродвигателей .The invention relates to electrical engineering, in particular, to the technology of manufacturing submersible electric motors.
Цель изобретени - повьшение ка- ч ества капсулировани путем обеспечени монолитн.ости и точности размеров заливки статоров, снабженных на торцах средствами дл установки герметизирующих элементов.The purpose of the invention is to increase the quality of encapsulation by ensuring the solidity and dimensional accuracy of the casting of stators, provided at the ends with means for mounting sealing elements.
На чертеже представлен статор с герметизированной полостью в процессе его заливки.The drawing shows the stator with a sealed cavity in the process of filling.

The speed of acceleration is chosen based on the pressure in the liquid compound of at least 0.05 MPa. The nozzle b is opened and the stator cavity is evacuated. The nozzle 5 is opened and the liquid compound is fed to the frontal parts of the windings 2, Under the action of centrifugal force. inside the evacuated stator cavity, the compound spreads along the winding grooves and, in the frontal parts, to fill the voids. Pipe 6 is disconnected from the vacuum system and depressurize the stator cavity, without stopping the stator rotation. The pipe 7 is opened, as a result of which the excess compound is squeezed out of the stator cavity under the action of centrifugal force to the level of the pipe 7 installation. The heaters 9 are turned on and the stator is heat treated in accordance with VNIIPI, Order 3975/53
