During the operation of Roots blower, the bearing must be checked frequently. Lubricating oil temperature in Roots blower equipment. Ammeter indication. When Roots blower needs cooling water, check whether the cooling water volume meets the specified requirements. If the fan has packing seal, check the leakage of the seal. If the leakage is serious, replace the seal immediately to avoid safety accidents caused by dangerous gas leakage, and the leakage of corrosive gas will also damage the bearing.
During the operation of Roots blower, attention must be paid to the indication of the ammeter. In case of any abnormality, stop the blower immediately for inspection. Most of the reasons are caused by the friction of the impeller. Don't think that the Roots blower in operation doesn't need to be looked at. On the contrary, it should be looked at carefully. Otherwise, a little carelessness will cause damage to the blower and affect its normal use.
When people order Roots blower equipment, they are most concerned about the price of this thing. If the price is too high, then they will be very worried about whether their purchasing ability can bear it. If it is urgent, this problem will become more acute.
In fact, according to the current market price, the price range of a normal small Roots blower is about 200 to 350 yuan, which should be regarded as the standard price of this equipment. For large ones, there are thousands. Roots blower will inevitably have various faults after being used for a long time,
The structure of Roots blower is simple. There are only two rotors in the casing. The friction phenomenon in operation can be divided into three types: friction between rotors, friction between two rotors and the casing, friction between two rotor end faces and the wall plate. The friction causes are as follows:
1. The shaft is not rigid enough. When the roots blower rotates, if the rigidity of the main shaft and driven shaft is not enough, it will produce torsional deformation (this deformation is within the elastic limit), which will cause friction between two rotors or between the rotor and the casing. At this time, the shaft shall be reprocessed to improve the rigidity or replace the shaft with strong rigidity.
2. The gear is worn. Especially when the two rotors of the blower are placed horizontally, the position of the two rotors changes after the gear is worn, resulting in friction between the two rotors. At this time, the gear should be overhauled or replaced with a new gear.
3. The gear keyway and key are loose. As the keyway and key become loose, the position of the two rotors will change, which will cause friction between the rotors. At this time, the key should be repaired or replaced to make it not loose.
4. Bearing clearance exceeds the specified technical requirements, and there are hard impurities in the transmission gas, which will cause friction between rotors. At this time, the bearing clearance should be readjusted or impurities in the gas should be removed.
I believe that after reading the above contents, you should also have some understanding of the causes of friction during the operation of Roots blower. I hope it will be helpful to you.
