It is very normal for the wind knife vortex air pump to malfunction after a period of use. So for daily technical operators, it is necessary to have a certain understanding of the wind knife vortex air pump to ensure the daily operation of the machinery and to have skills to maintain it after faults occur, so as to better reduce the maintenance costs of the enterprise. So companies should strive to cultivate more skilled talents to apply to their positions. Today we will introduce to youWind knife vortex air pumpMaintenance methods for malfunctioning.
Wind knife vortex air pumpMain faults and causes:
1. Severe vibration of the bearing box;
① The vortex air pump shaft is not concentric with the motor shaft, and the coupling is installed incorrectly
② Friction between the casing or air inlet and the impeller
③ The steel degree of the foundation is not firm enough
④ Loose rivets on the impeller or deformation of the impeller
⑤ The impeller shaft and shaft are loose, or the coupling bolts are loose
⑥ Loose connecting bolts between the casing and bracket, bearing box and bracket, bearing box cover and seat, etc
⑦ Poor installation of inlet and outlet pipelines for vortex air pump
⑧ Unbalanced rotor and worn induced draft fan blades
2. The temperature rise of the bearing is too high;
① Severe vibration of the bearing box
② The quality of lubricating grease is not bright, deteriorated, and contains excessive impurities such as dust, sticky sand, and dirt
③ The tightening force of the connecting bolts of the bearing box cover and seat is too high or too low
④ The installation of the shaft and rolling bearings is skewed, and the front and rear bearings are not concentric
⑤ Damage to rolling bearings
3. Excessive electrode current or high temperature rise;
① The intake pipe gate or throttle valve is not tightly closed while driving
② Traffic exceeds the specified value
③ The density of the gas transported by the vortex air pump is too high or there are viscous substances
④ Motor input voltage too low or single-phase power outage
⑤ The coupling connection is not correct, the leather ring is too tight or the gap is uneven
⑥ Affected by severe vibration of the bearing box
Wind knife vortex air pumpMaintenance and upkeep:
1. Maintenance carried out when the noise of the air pump increases
First, check if there are any debris inside the vortex air pump body. If so, open the casing and clean the internal debris; Next, check if the impeller is stuck. At this point, the manufacturer will repair it and reassemble it to eliminate the fault. Check if the bearings are damaged and replace them if necessary.
2. Maintenance performed when the pump temperature rises
First check if the air inlet is blocked, clean the air inlet filter, but do not remove it, otherwise it will suck in debris and damage the mechanical equipment. Please maintain the working time gap of the air pump appropriately. Next, check for any debris inside the body, open the outer shell, and clean up the internal debris.
