Answer: there are two possible reasons for the oil leakage of Roots blower:
1、 The liquid level in the oil tank is too high, and the oil leaks from the oil drain. At this time, the liquid level of the oil tank should be reduced.
2、 Seal wear causes oil leakage at the shaft end, and the seal may need to be replaced at this time.
The air vents of the wall panel and the oil tank are blocked, causing oil to leak into the housing. At this time, the vent should be dredged, and a 2mm hole cock should be installed in the middle chamber to open the cock under the wall panel.
Customers who use roots blowers know that they should refuel in time. If they add more, this will happen. At this time, they only need to draw out a part to reduce the liquid level of the oil tank to ensure that the lubricating oil is not lower than the liquid level line marked on the housing!
Generally, roots blower needs to be maintained every three months. The maintenance content is to completely change the oil. The upper and lower oil plugs of the oil tanks on both sides should be tightened, otherwise oil leakage will also be caused.
The first reason is that the fan has a certain service life, and the seals are not replaced as required. The worn seal causes oil leakage at the shaft end. Don't worry about this. Arrange the corresponding mechanic to remove and replace the seals of Roots blower!
At the same time, it is also necessary to check whether the bearings and gears are worn. After wear, the clearance will increase, resulting in oil leakage. In this case, it is only necessary to return to the factory to replace the parts, which belongs to the normal wear and tear of the equipment
The second main reason is that the processing capacity of the equipment is not up to standard, the processing of the oil tank port is not up to standard, the oil tank material is not up to standard, and the quality problem leads to oil leakage. This kind of situation used to be very common, but now with the progress of domestic manufacturing technology, this kind of situation is very rare!
Another common reason is that due to the high pressure of high-pressure water-cooled roots blower, improper water-cooling measures during operation will lead to oil outlet. In this case, a better exhaust valve can be replaced. The high-quality exhaust valve is spiral, which effectively solves the oil problem!
Oil leakage at the oil filler of Roots blower
Oil leakage is a common minor fault in the operation of Roots blower. There are many reasons for oil leakage, and the corresponding solutions are also different. The following are the reasons and Countermeasures for the oil leakage of Roots blower.
The high lubricating oil level in the tank of Roots blower is an important reason for oil leakage. When the lubricating oil level is high, the oil will penetrate into the wallboard from the oil seal and leak from the air hole under the wallboard. Obviously, the solution is to reduce the oil level to normal level.
Seal failure is another important cause of oil leakage. There are oil tanks on both sides of Roots blower. Since gears and bearings need lubricating oil for lubrication, but oil is not allowed in the housing, oil seals must be provided to prevent lubricating oil from entering the housing from the oil tank. If the oil seal is aged and fails, or the connection between the oil seal and the shaft is worn, resulting in seal failure, even if the lubricating oil level is normal, the oil thrown out by the gear or oil pan may enter the wall panel from the failed seal and leak from the air hole under the wall panel. If the gas seal on the shaft also fails, for example, if the rising ring seal is different from the shaft sleeve, the oil will enter the housing along the shaft and mix with the gas, polluting the user's system. The solution is to restore the sealing effect, such as replacing the invalid oil seal, repairing the connection between the oil seal and the shaft, and correcting the rising ring seal.
If the ventilation hole at the lower part of the wall panel is blocked, or the return air duct is blocked, more and more oil leaks enter the wall panel, and the oil will also penetrate into the shell from the gas seal. Therefore, the solution is to open the vent plug at the lower part of the wall panel and dredge the return air duct.
When the oil tank cracks, the welded joint of the welded oil tank will crack. If the connection between the oil tank and the wall panel is not tight, the lubricating oil will leak along these places. Then repair welding, tighten the connecting bolts between the oil tank and the wallboard, replace the oil tank, and solve the problem of oil leakage.
There is an oil drain under the main oil tank and auxiliary oil tank of Roots blower. If the plug of the oil drain port is not tightened or tightened, oil may leak from the oil drain port. Tighten the plug so that the oil will not leak out.
Therefore, if the roots blower is found to be leaking oil, we can find out from the above reasons and take countermeasures. To sum up, the oil leakage at the oil filler of Roots blower may be due to the problem of seals. Please check the wear of the seal in time and replace it in time!
