Let me introduce to you the problem of abnormal noise of Roots blower.
Roots blower to carry out commissioning work, how to do?
After installing the three-leaf Roots blower, the next work to be done is the trial operation and adjustment of the blower. When buying the Roots blower for the first time, because the operation content is not clear, please look at the content here first.
1. Inspection of bolts
After installing the root fan, check whether the bolts are tightened, whether the base is tilted, and whether the fan is in a horizontal position before the trial operation.
2. The problem of running load
The fan will start without load during trial operation and startup, so it cannot be started under load. Load startup will cause damage to the fan.
3. Check for impurities
Before operating the blower, check whether there is garbage, garbage, such as welding debris, etc. on the piping, and reconfirm whether the piping, valves, etc. are installed correctly.
4. Check the amount of lubricating oil
Confirm the amount of lubricating oil before turning on the power supply. The oil mark of lubricating oil should be at the red line position indicating the oil hole. Do not add too much lubricating oil, which will automatically discharge and cause oil leakage.
5. Check with the disk moving fan
Move the front wheel, drive the pulley, confirm that the blower can rotate normally, and confirm that there is no abnormality before starting the blower.
6. Monitoring of abnormal conditions
When abnormal sound, high heating temperature, increased vibration and increased current occur during the trial operation of the fan, please be sure to stop and check quickly, and then turn on the power supply for operation after troubleshooting.
What is the reason for the abnormal sound of the Roots blower?
1. The impeller rotor of the three-blade Roots fan fails, and there is a lot of friction between the impeller and the impeller. The rough production of the impeller will increase the friction and increase the abnormal noise.
2. Because the box manufacturing does not meet the standard, the use time is long, the three-blade root fan box is deformed, and the impeller and the box friction.
3. The use of the bearing, the bearing accessories do not meet the standards, there are quality problems, the three-leaf Roots blower will make abnormal noise.
4. Sealing problem. Because the blower is the principle of forced air supply, if the air shuttles back and forth due to incorrect sealing, the air will hit the blower wall and produce abnormal noise.
5. Lubricating oil problem Roots blower due to poor import and export, unable to exhaust, the pressure continues to rise, on the contrary will affect the rise of current, the machine will produce abnormal noise, so the correct maintenance must be filled with lubricating oil.
According to the correct use of Roots blower, regular and quantitative detection and maintenance every day have a good effect on the long-term use of Roots blower, which can be used with confidence and prolong the life of Roots blower.
The above are the reasons and countermeasures for the abnormal noise of the Roots blower. In a word, on the basis of using good quality parts, we use the Roots blower in a timely manner, not laissez-faire, but for long-term use, we need to nourish him and let him Keep checking and maintaining.
