Protection of Ventilation Pressure for synchronous Motor

通过对球磨机的同步电机电器设备进行通风正压保护，阻止了有害物质的进入，延长了设备的使用寿命，降低电器设备的维修工作量和维修成本，提高工作的安全性和生产效率，具有推广应用价值。

The paper introduces the positive pressure ventilation protection for the electric device of the synchronous motor for a ball mill in order to prevent harmful substances from entering the device, thus increasing the service life of the electric device, reducing maintening work labour and expenditure, and improving work safety and production efficiency. The scheme for Protection of ventilation pressure has the value of popularization and industrial application.
