Roots blower in the process of using the bearing can not be separated from the lubrication of the work, then the Roots blower bearing lubrication and maintenance aspects need to do those jobs?Roots BlowerI'll take you through it.
Roots blower bearings, its role should be to support, that is, the literal interpretation is used to bear the shaft, but this is only part of its role, support its essence is to be able to bear the radial load. Can also be understood as it is used to fix the shaft. Is to fix the shaft so that it can only realize the rotation, and control its axial and radial movement.
Roots blower bearings will have a direct impact on the impeller is easy to hold, can not pass the rotation, most of this situation has to do with the failure of the bearing damage, through the disassembly and inspection can be seen in the reason. Roots blower if running all year round, bearing wear and tear is also very large, so fan manufacturers to ensure the quality of the fan, choose the brand of bearings is very necessary.
Roots blower bearings, in the process of using the fan, the need for fan users often lubrication and maintenance work: check the Roots blower bearing lubricant oil supply, if the box appears to be leaking oil, you can tighten the bolts of the end cap a little, if not, it is necessary to change the new sealing filler.
Such as Roots blower on both sides of the tank design: add industrial gear oil, through the rotation of the equipment, the oil will be in contact with the bearings, to ensure that the bearing lubrication and cooling; regularly add a certain amount of oil to ensure that the oil level of the oil tank can be used without fear. Fan first use, in the operation of 240 hours or so for oil change; the second oil change time in about 45 days to carry out; after that should be weekly inspection of lubricating oil, such as lubricating oil is too dirty or deterioration, to be completely dirty oil change; such as lubricating oil does not deteriorate, then the oil change work can be extended to 150 days or so to replace; Note: must use the specified grade of lubricating oil.
Such as Roots blower single tank design: gear side of the bearing design has a tank; pulley side design is no tank structure, through the filling of solid lubricant (grease) for lubrication. Advantages of this design: fan price cost is lower, cheaper to buy; shortcomings: grease to refueling frequency is high, according to the use of general 1 week - 2 weeks plus once, easy due to lack of maintenance caused by lack of oil bearing damage.
Roots blower bearings, if replacement is necessary, must be required to be clean and clear of the bearings and bearing box before the new bearings are put in. Place the bearings in oil at a temperature of about 70-80°C to heat them before fitting them to the shaft, and do not force them to be assembled to avoid unnecessary damage to the bearings.
