The disassembly of Roots blower is a complex and meticulous process that requires careful operation. The following are the detailed steps and precautions for disassembling Roots blower:
1、 Disassembly steps
1. Disconnect the power supply:
Before dismantling, the power must be disconnected first to ensure that the fan is in a stopped state to prevent accidental start-up or electric shock hazards.
2. Dismantling of import and export pipelines:
Remove the bolts connecting the inlet and outlet pipes of the fan, and separate the inlet and outlet pipes from the fan. Be careful during this process to prevent damage or detachment of the pipeline.
3. Dismantling the cover and transmission components:
Remove the cover and the bolts of the V-belt (or elastic coupling) to separate the drive belt (or coupling) from the fan.
4. Dismantling the casing:
Remove the upper casing, baffle, and gearbox cover. Next, remove the outer bearing cover of the pulley and the upper covers of the left and right sealing bodies.
5. Lift out the rotor:
Carefully lift the active rotor and passive rotor out using lifting tools.
6. Dismantling bearings and gears:
Remove the thrust bearing box and take out the bearing, then remove the gear back cap and detach the gear from the shaft.
7. Disassemble the sealing device and lower baffle:
Disassemble the left and right sealing device seats and lower baffle to ensure that all components are properly stored for subsequent reassembly.
2、 Precautions
1. Cleaning and protection:
During the disassembly process, it is necessary to keep the operating table clean and avoid losing or confusing small parts. Meanwhile, all parts should be properly stored after disassembly to prevent contamination and impurities.
2. Handle with caution:
When disassembling bearings, seals, and rotor components, care must be taken to avoid damaging these critical components. Internal components with maze plates must be carefully disassembled and stored.
3. Marking and recording:
During the disassembly process, the assembly marks and positions of each component should be carefully checked and recorded to ensure accurate alignment during reassembly. At the same time, all problems and abnormal situations discovered during the disassembly process should be recorded for subsequent maintenance and reference.
4. Double headed bolt processing:
If the Roots blower uses double headed bolts, these bolts may have pointed threads and should be carefully screwed to avoid damaging the threads or causing other damage.
5. Protection:
Throughout the entire disassembly process, it is necessary to always follow the operating procedures and wear necessary protective equipment such as gloves, goggles, etc. to prevent injury.
6. Reassemble:
After disassembly, the Roots blower should be reassembled in the correct order and method. All matching parts, locating pins, and mating keys must be aligned according to their assembly markings to ensure correct assembly. At the same time, the integrity of key components such as gaskets and circular seals should be checked, and any damage should be replaced promptly.
In summary, dismantling a Roots blower is a process that requires meticulous operation and strict adherence to steps. By proper disassembly and maintenance, the service life of Roots blowers can be extended and the normal operation of the equipment can be ensured.
