Analysis of Oil Leakage Causes and Solutions for Roots Blowers
There are various reasons for oil leakage in Roots blowers, and the following is an analysis of these reasons and corresponding solutions:
1、 Analysis of Oil Leakage Causes
1. Impeller and gear issues:
There are pollutants and impurities in the impeller, which cause the spacing to be too small and may lead to oil leakage.
The gears are severely worn and the side clearance increases, affecting the sealing effect.
The gears are not fixed properly, resulting in the impeller being unable to operate synchronously and increasing the risk of oil leakage.
2. Bearing wear:
After long-term operation, bearings wear out, leading to increased clearance and easy leakage of lubricating oil.
3. Oil tank and oil level issues:
The oil level in the fuel tank is too high, and the oil is prone to overflow.
There are quality issues with the fuel tank, such as cracks or damage, leading to oil leakage.
The structural design of the fuel tank is unreasonable, such as the lack of an oil blocking device, which causes the lubricating oil to splash and leak.
4. Aging or damage of seals:
After long-term use, the sealant or sealing ring will age and lose its sealing effect.
Improper installation or damage of seals can lead to oil leakage.
5. Pressure and temperature issues:
The operating pressure of the fan is too high, exceeding the specified value, resulting in oil leakage at the seal.
The working temperature is too high, causing the lubricating oil to become thin and increasing the risk of leakage.
6. Design and manufacturing issues:
The fan design is unreasonable, such as poor sealing structure of the joint surface.
Insufficient manufacturing accuracy leads to poor coordination between components, resulting in oil leakage.
2、 Solution method
1. Cleaning and adjustment:
Inspect and repair the internal components for contamination and impurities on the impeller.
Adjust the gear clearance. If the gear backlash is too large, the gear should be replaced.
Reinstall the gear to ensure that the taper fitting contact area reaches the specified value.
2. Replace bearings:
Check the wear of bearings and replace severely worn bearings in a timely manner.
3. Adjust the fuel tank and oil level:
Reduce the oil level in the fuel tank to avoid oil spillage.
Check and repair any cracks or damages in the fuel tank.
Improve the structure of the fuel tank, such as adding oil blocking devices to prevent lubricating oil from splashing and leaking.
4. Replace the seal:
Check and replace aged or damaged sealant and sealing rings.
Ensure that the seals are installed correctly and securely fastened.
5. Control pressure and temperature:
Master the reasons for overloading and reduce the pressure to within the specified value.
Check installation accuracy, reduce pipeline tension to lower working temperature.
Open ventilation openings to reduce indoor temperature and prevent excessive inlet temperature.
6. Improve design and manufacturing:
Optimize fan design and improve the sealing structure of the joint surface.
Improve manufacturing accuracy and ensure good fit between components.
In summary, it is necessary to analyze and solve the oil leakage problem of Roots blower from multiple aspects. By cleaning and adjusting, replacing bearings, adjusting oil tanks and levels, replacing seals, controlling pressure and temperature, and improving design and manufacturing, the oil leakage problem of Roots blowers can be effectively solved to ensure their normal operation.
