What are the common faults typically encountered in stainless steel Roots blowers? If the mechanical parts of a stainless steel Roots blower—such as the sound, ambient temperature, and vibration—are normal, yet the blower produces a low, muffled sound and the current draw is relatively high, the primary causes are usually poor air intake and exhaust, blockages or accumulation of dust in the inlet filter and casing, failure to open the exhaust valve, or obstructions in the exhaust path.
Stainless steel Roots blower What are some of the more common malfunctions?
1. High current rating
If the mechanical parts of the stainless steel Roots blower are operating normally in terms of sound, ambient temperature, and vibration, yet still exhibit a somewhat muffled tone and relatively high current draw, the primary causes are typically poor air intake and exhaust performance—specifically, a clogged or blocked inlet filter, accumulation of dust inside the housing, and failure to open the exhaust valve.
2. Rolling bearing overheating
During operation, overheating of the rolling bearings in stainless steel Roots blowers is commonly caused by bearing damage, inadequate lubrication, or excessively tight drive belts. If a bearing fails, you’ll definitely notice it right away—just listen for the sound.
3. The gearbox is making unusual noises.
An abnormal noise from the gearbox is associated with gear surface wear and inadequate lubrication. If uneven impacts occur, this is typically a sign of a key or retaining ring failure, and it could also indicate damage to the rolling bearings or spalling.
4. Abnormal sounds are detected inside the machine cavity.
If there’s a squeaking sound inside the machine cavity, it could indicate that the bearings are no longer properly aligned. If there’s a collision, it usually means the rolling bearings have already been damaged, the pitch of the centrifugal impeller has changed, and the side of the centrifugal impeller is no longer evenly spaced from the surrounding wall. Another possible scenario is that debris has adhered to the centrifugal impeller—but this is relatively rare.
5. The synchronous belt has been found to have an abnormality.
If a synchronous belt is damaged and starts shedding debris, it could be due to the belt making contact with the bottom of the groove, unequal belt tensions, the belts not being aligned in the same plane relative to the groove, or uneven wheel surfaces.
6. The fan current is high, and it operates under overvoltage conditions.
High current and overpressure in the fan often indicate blockages in the dry system piping. Here, I’d like to emphasize: Be sure to properly calibrate the valves, release excess air to relieve overpressure, and never allow the fan to operate under excessive pressure.
How should a stainless steel Roots blower be maintained when it's raining?
1. Exposing the stainless steel Roots blower to the elements makes its screws highly susceptible to rusting. Therefore, after it rains, you should promptly clean the anchor bolts and apply unsalted butter onto their surfaces to prevent direct contact between the bolts and the external air.
2. Once the paint has been washed away by rainfall and then exposed to intense sunlight, it may start to flake off. If the flaking paint is subsequently cleaned away by rainwater, rusting is likely to occur. Therefore, it’s important to promptly apply a fresh coat of paint once the existing paint has begun to peel, in order to prevent further paint deterioration.
3. Turn on in rainy weather Stainless steel Roots blower It also poses certain risks to silencers—there’s a possibility that rainwater could enter the silencer. For silencers used with stainless steel Roots blowers, it’s important to ensure they’re properly sealed during rainy weather.
4. Precipitation can also affect the electrical wiring of wind turbines. Both prolonged exposure to sunlight and rainfall can cause weathering of the electrical wiring, leading to short circuits and potentially triggering power surges that result in the system shutting down.
