How to solve the high temperature of Roots blower

1. The oil in the tank is too much, too thick, and dirty; The oil level should be lowered

2. The filter or muffler is blocked; Blockage should be clear in time

3, the pressure is higher than the specified value; The pressure difference through the blower should be reduced

4, impeller excessive wear, large clearance; Clearance should be repaired

5, poor ventilation, high indoor temperature, resulting in high inlet temperature; Air vents should be opened to lower the room temperature
