Positive pressure ventilation for motors
Thread Content
The function and principle of positive pressure ventilation in motors
Its function is to use purified air or unpurified air to displace any combustible gases that may be present inside the motor, thereby preventing explosions caused by sparks when the motor is started
Positive pressure ventilation in electrical equipment is used to prevent the entry of flammable gases, thereby achieving explosion protection.
Use clean air to fill the motor compartment and create positive pressure, thereby preventing flammable and explosive gases from entering
There are two ways: 1. Drive-through purging type. After purging and once the conditions are met, the motor can be started. 2. Regular purging type. Loss of pressure = loss of protection. It depends on the method used by the motor.
