Roots FansIn the process of use will inevitably meet the failure, then what causes the failure to occur? The following Roots fan editorial take you to understand.
I. The cause of impeller-impeller friction:
1. There are polluting impurities on the impeller, causing the clearance to be too small;
2. The gears are worn, resulting in a large backlash;
3. The gears are not fixed securely and cannot keep the impeller synchronized;
4. Bearing wear.
Second, the cause of the impeller and the wall plate and housing:
1. Incorrect installation clearance;
2. Deformation of the casing or seat;
3. The operating temperature is too high;
4. Bearing axial positioning problem;
5、Operating pressure is too high, exceeding the specified value.
(c) The main reason for the high temperature:
1, environment, poor ventilation in the machine room, high indoor temperature;
2. The pressure is higher than the specified value;
3. Excessive wear and tear of the impeller and large clearance;
4. The oil level in the tank is too high or too dirty;
5. Filter or muffler clogging;
6, running speed is too low, belt slack slip or broken.
IV. Main reasons for insufficient flow:
1, impeller wear, clearance increased;
2. Inlet filtration clogging, high inlet pressure loss;
3. Broken pipes and ventilation leaks.
4. Belt slippage;
