Installation instructions of Roots blower for coal washing machine
1. The indoor temperature of the sewage treatment Roots blower should be lower than 40°C. If the temperature exceeds 40°C, the life of the blower and motor will be greatly shortened. Please set a ventilation fan to ensure that the room temperature is below 40°C. When the temperature is lower than 0°C in winter, it should be noted that the gear oil will freeze and the temperature will rise after a period of time.
2. The foundation should be firm, the surface should be flat, and the foundation should be higher than the ground.
3. The space around the fan should meet the requirements for fan disassembly and maintenance.
