Chengdu Roots Blower Factory Talking about the Use of Roots Blower Lubricating Oil


1, detection of lubricating oil is not air mildew, if you have air mildew, can be identified from the appearance. At this time, the color tone of the lubricating oil turns black or becomes deep, and the surface layer produces hard ridges.


2. Test whether lubricating oil is mixed with many hard grain magazines and periodicals. When testing, take a little lubricating oil by hand to carry out twisting and pressing, which can be determined by intuition.


3. Different types of lubricating oil cannot be mixed, and new oil and old oil cannot be mixed. Therefore, when replacing lubricating oil, waste oil should be eliminated first, and then new oil should be replaced.


4. The addition of lubricating oil should be appropriate. Less addition will lead to insufficient lubrication, excessive addition, excessive mixing of lubricating oil, substantial temperature increase, and oil separation, dissolution and leakage.

Here, I want to tell you that if the Roots blower leaks more seriously during operation, the traditional method is to shut down, disassemble and replace the sealing gasket and handle the joint surface for a long time. The traditional way is not possible to complete the machine running control. At present, the lubricating fluid sold on the market is a refined oil additive, which does not destroy the refined oil, makes the oil mildew, and does not shut down to overcome the danger in factory production.


Chengdu Roots Blower Factory: Causes of Hot Rolling Bearing of Roots Blower


Hot 1. rolling bearing


When running, the rolling bearing of Roots blower is hot. It is often caused by the damage of the rolling bearing and the poor lubrication and the large transmission belt. If the bearing fails, the sound will follow and you will know it at a glance.


Abnormal sound in 2. machine cavity


If there is a squeak in the machine cavity, it may be that there is a problem with the precise positioning of the bearing. If there is a collision, the rolling bearing has already been destroyed, the center distance of the centrifugal impeller has changed, and the side of the centrifugal impeller is not equal to the wall surface. There is also a situation, there may be sticky dirt on the centrifugal impeller, but the probability is very small.


3. centrifugal fan with large current and overvoltage operation


The centrifugal fan has large current and overpressure, which is mostly attributed to the blockage of system pipelines. Here, I mainly want to remind you that the valve must be corrected, the overpressure is released, and the overpressure operation of the centrifugal fan is prohibited.


High 4. current


If the sound, ambient temperature and vibration of the mechanical part of Roots blower are normal, but it is also low and the current flow is relatively high, it is generally because the air inlet and outlet are not good, and the imported filter, shell ash collection and exhaust valve are not opened and blocked.


Abnormal sound of 5. reduction gearbox


The abnormal sound of the reduction gearbox is related to tooth surface wear and poor lubrication. If uneven collision occurs, it is the fault characteristic of key or circlip, or the rolling bearing may be damaged or collapsed.


6. timing belt found abnormal


If the timing belt is damaged and slag falls off, it may be that the transmission belt touches the bottom of the groove, the two belts are not equal or the relative groove is not on the same plane, the wheel is not smooth, etc.
