Roots blower is a volumetric rotary fan, and its main power source is motor, diesel engine or motor diesel hybrid type. The main parameters for selection include air volume, pressure, speed, motor power, etc.
Roots blower has two impellers (Figure 2, the part in the circle). Driven by the motor, the two impellers will rotate towards each other. When the impellers rotate past the air inlet, a sealed chamber will be formed between the two impellers and the wall plate and the casing. If the impellers continue to rotate, the air in the sealed chamber will be pressed into the exhaust port, and so on, it will repeatedly pass through the air inlet and exhaust port, Deliver the outside air to the destination.
There will be some gaps between impellers, between impellers and wallboards, between impellers and casings. The gaps have fixed standards and errors. Excessive errors will cause other corresponding problems. When the impeller passes through the exhaust port, under the effect of the pressure in front of the pipe, part of the gas will leak to the outside through the gap. Such leakage is called internal leakage.
1. Air volume decreases
The destruction of the impeller will certainly cause the expansion of the gap in the middle of the centrifugal impeller. The expansion of the impeller gap will cause the expansion of the internal leakage of the fan, endanger the effective air volume, cause the reduction of the effective air volume, and endanger all normal use of everyone.
2. Noise expansion
The friction between the impeller and the middle of the impeller will cause a lot of industrial equipment noise. This kind of industrial equipment noise will expand the overall noise of the fan, and the noise pollution will expand. What adverse effects will be caused by Roots blower impeller, Roots blower, fan impeller maintenance, and damaged Roots blower impeller
3. Impeller damaged The impeller is damaged, and the friction between the impellers is serious, which will cause cracks in the impeller. The quality of raw materials for the impeller is not good, and the probability of cracks in the impeller will be greatly increased. 4. Burn the motor
For high-speed rotating Roots blower, if the impeller is damaged suddenly in serious condition during the whole operation process, the motor will be burned, resulting in motor damage.
5. Burn roller bearing
Damaged roller bearings are also aimed at high-speed rotating fans. High speed rotation will endanger the use of roller bearings. The impeller destruction will continue to cause many heating values again. It is also a kind of damage to roller bearings. Damaged roller bearings will prevent the fan from working.
6. The seal is damaged
The temperature resistance performance of the seals of Roots blower is within a certain level, and the accumulation of many calorific values will seriously threaten the use of the seals.
