After the aerator is disassembled and installed, the noise becomes abnormally loud!
Solution: This problem has been encountered by many customers in the use of many customers, that is, the fan that has been running for several years, because it is disassembled and re-installed! When working, the noise becomes very loud, and it is accompanied by abnormal noise! The noise is obviously different from before disassembly! So what is the reason for this!

The above problems occur mainly because of the situation caused by the user during the installation! Due to professional technical learning, it is very easy to adjust the gap of the blower inappropriately during installation! At the same time, it also includes the fixation between the gear and the gear! Here, if you need to repair the equipment, it is recommended to find a professional manufacturer to debug it for you! In this way, the above problems can be avoided! Since the gap between the impeller and the impeller inside the blower is very small, about 0.2mm, it is easy to deviate if it is slightly inaccurate during installation. If the deviation is too large, it will easily lead to the collision and damage of the impeller, and even the rotors are broken.


Under what circumstances does the aerator need to be cooled with water?
Conventional Roots fans are generally cooled by air cooling, mainly natural heat dissipation! In the case of the machine temperature is not high, you can choose! It can mainly be seen that the wind pressure is between 9.8-58.8kpa, and it is recommended to choose air-cooled cooling! If the pressure exceeds 68-70kpa, the user needs to use water cooling to cool down. At this time, the temperature of the machine itself is relatively high, and it needs to be cooled by water cooling!



What type of oil is usually filled in the aerator?
Many customers who use Roots blowers do not know what type of oil to add in the fuel tank, and do not know what kind of oil to add, whether it is gear oil, hydraulic oil, or engine oil! Under normal circumstances, the Roots blower is added with N220 load gear oil!

It is correct to add N220 gear oil, each oil has quality, different viscosity and different hot spots! Therefore, it is recommended that users do not add wrong! Regularly check whether the cursor is short of oil, and add it regularly, mainly to cool the gear! When the machine has been running for 8-12 months, the user can change the oil once! The daily maintenance of the fan is done correctly, which effectively ensures the service life of the equipment.


How much PVC pipe does the aerator need to be connected to in aquaculture?
Today, I will tell you about the connection between the Roots aerator and the supervisor in aquaculture, including how big the supervisor should be! In general, most of the PVC pipes are used in aquaculture, mainly because the cost will be lower, and the pressure of the fan is not very high for PVC, because the wind pressure generated by the fan is very low at about 10-58.8kpa. Users can imagine whether the PVC pipe will be damaged when it is placed in a water depth of 5-6 meters. It is such a simple truth! So don't worry about the wind pressure, the PVC pipe is enough!

So how big is the supervisor in general? The general users of conventional breeding mostly use supervisors of DN50 and DN63! This is mainly aimed at breeding users between 4-25 acres. In this area, it is enough to use the supervisors of these two calibers!
