Detailed steps for dismantling Roots blower
The disassembly steps of Roots blower are usually followed in order to ensure the safety and integrity of the disassembly process. Here is a detailed disassembly procedure guide:
1、 Preparation work
1. Power outage and identification: Firstly, ensure that the Roots blower has been powered off and identify all connecting and fitting parts, especially key components such as gears, for accurate resetting during subsequent assembly.
2. Tool preparation: Prepare necessary disassembly tools such as wrenches, screwdrivers, screwdrivers, copper hammers, lifting devices, etc.
2、 Disassemble external components
1. Disassemble the inlet and outlet air ducts: Loosen the connecting bolts between the inlet and outlet air ducts and the machine body, and remove the inlet and outlet air ducts.
2. Disassemble the cover and transmission part: Remove the cover, then disassemble the bolts of the V-belt (or elastic coupling), and remove the V-belt pulley (or coupling).
3、 Disassemble the casing and gearbox
1. Dismantling the casing: Remove the upper part of the casing and the baffle, and then remove the gearbox cover.
2. Dismantling the gearbox: Remove the lubricating oil from the gearbox, and then disassemble the gearbox and its adjusting screws. Pay attention to protecting the components inside the gearbox to avoid damage.
4、 Disassemble internal components
1. Dismantling bearings and seals: Remove the outer bearing cover of the pulley and the upper covers of the left and right seals, and then take out the bearings.
2. Lifting out the rotor: Use lifting tools to carefully lift out the active and passive rotors. During the lifting process, ensure that the rotor is not damaged.
3. Dismantling gears: Disassemble the thrust bearing housing and remove the bearing, then remove the gear back cap and take out the gear. Pay attention to keeping the gears clean and intact.
4. Disassemble the sealing device and baffle: Disassemble the left and right sealing device seats and the lower baffle.
5、 Precautions
1. Protecting components: During the disassembly process, special attention should be paid to protecting the components, especially the mating surfaces, to avoid scratches or damage.
2. Measurement of gasket thickness: All gaskets should be measured for thickness during disassembly to facilitate accurate resetting during subsequent assembly.
3. Avoid dust pollution: Disassembled components, especially precision components such as bearings, should be careful to avoid dust pollution. Clean cloth or plastic bags can be used for wrapping and protection.
4. Use appropriate tools: Proper disassembly tools should be used to avoid using violence or improper tools that may cause damage to components.
5. Waiting for cooling: If the fan has just been stopped, wait for the body and lubricating oil to cool down before disassembling to avoid.
6、 Subsequent work
1. Record the disassembly process: During the disassembly process, each step of the operation and the status of key components can be recorded for reference during subsequent assembly.
2. Check components: After disassembly, all components should be inspected, especially the mating parts for damage or wear. If necessary, repair or replacement should be carried out.
3. Disassembling according to the above steps can ensure that the dismantling process of the Roots blower is orderly. At the same time, paying attention to the details and precautions during the disassembly process can protect the integrity of the components and lay a good foundation for subsequent assembly and maintenance work.
