The causes and solutions of Roots blower overload are as follows:

1. The motor is overloaded. Cause: the selected parameters are unreasonable, and the working pressure is high, exceeding the rated value; The inlet filter is blocked, the pipeline does not match, or the outlet pipeline is blocked or blocked; Excessive vibration; The voltage of power supply system is too low; The resistance of all rotating mating pairs (bearings, shaft sleeves, gears, seals, etc.) is high. Solution: correctly select parameters and adjust the working pressure to the rated value; Clean the filter, arrange the pipe reasonably and block the objects; Check the working vibration of the fan and change the power supply line; Check all rotating mating pairs (bearings, shaft sleeves, gears, seals, etc.).

2. The pipeline causes ventilation leakage. Cause: The pipeline is blocked or broken. Solution: check and pipe.

The above information is for reference. When the Roots blower is overloaded, please stop it immediately to avoid accidents, and find personnel to repair and inspect it.
