Causes of Seal Wear in Biogas Booster Fans and Solutions When the biogas booster fan drives the drive shaft to rotate via a coupling or pulley, the gears mounted on the driving wheel simultaneously rotate in the opposite direction, driving the gears on the driven wheel to rotate in synchronization, thereby causing the meshing rotors to rotate together.
Biogas booster fan Causes of Seal Wear and Solutions
When the fan drives the drive shaft via a coupling or pulley, the gears mounted on the driving wheel synchronously rotate in opposite directions, driving the gears on the driven wheel to turn in tandem. This causes the meshing rotors to rotate together. To create a space between the housing and the rotors, gas enters this space through the gas inlet. In this process, one rotor compresses the gas while pushing it toward the outlet, while the other rotor, at the start of its rotation, compresses against the first rotor, forming a new space on the opposite side of the housing. New gas then enters this newly formed space and is subsequently expelled. Now, let’s take a closer look at the causes of seal failure in methane booster fans and the corresponding solutions! 1. The general principle—whether the intake and exhaust are arranged vertically, or vertically and horizontally—is typical for most methane booster fans. When the motor drives the transmission shaft via a coupling or pulley, the gears mounted on the driving wheel synchronously rotate the gears on the driven wheel, causing the meshing rotors to rotate in unison. As the rotors rotate, they form a space between the housing and themselves, allowing gas to enter this space through the inlet. The gas is compressed by the rotors and forced out through the outlet, while the other rotor, at the onset of compression, faces the first rotor, creating a new space on the opposite side of the housing. New gas then enters this space and is expelled outward.
The imported silencer features a mesh-shaped air inlet equipped with a filter element. When the inlet silencer is opened, you can clearly see the filter element yourself. There are no filter elements or other silencer accessories included. As for the outlet pressure gauge: if the student’s company does not have a Chinese import-export silencer, and you check the location where the pressure gauge is installed, then the product being exported is from our country; otherwise, it’s an import from another country. You can also observe the rotation direction of the protective band—by continuously monitoring its rotation direction, you can determine whether personnel are entering or exiting the area. Biogas booster fan Causes of Seal Wear and Solutions: Addressing Shaft Bending Issues: Straighten the shaft; Resolving Main Issues Caused by Bushing Deformation: Repair and eliminate the impact of such deformation; Teaching Methods for Excessive Bearing Clearance: Adjust the bearing clearance or replace the bearing; Solutions for Sliding Bearing Misalignment: Adjust or replace the sliding bearings; Remove foreign objects from within the sealing ring; If necessary, improve technical procedures; Check whether the rotor’s mass has achieved balance; The coaxiality error between the sealing ring and the shaft sleeve must not exceed a specified standard—research and implement solutions: Replace worn parts and adjust coaxiality; Gas Pressure
Precautions for the Operation and Maintenance of Biogas Booster Fans: Pay attention to sealing to prevent leaks. In case of methane explosion due to open flames, regularly check the sealing condition. Monitor the temperature of the entire unit and the biogas booster fan, and keep detailed records accordingly. Compare the temperatures of the entire unit in stages. Remove internal impurities; the biogas booster fan should be cleaned regularly. Excessive internal impurities can affect the fan’s operation. It is also crucial to regularly clean oil stains inside the fan. Periodically inspect the lubricating oil in the oil tank. If the oil level is insufficient, promptly top up the oil tank. If there are any changes in oil quality, replace the lubricating oil immediately. The above outlines the causes of seal wear and tear in biogas booster fans, as well as solutions to these issues.
