The removal method of Roots blower is bearing removal, which generally starts from the removal of bearing pedestal. There are usually 2-4 process thread holes for disassembly on the flange of the bearing block. During disassembly, remove the bolts between the bearing pedestal and the wallboard first, and then screw the screws into the process screw holes, then the bearing pedestal can be jacked off from the wallboard joint surface. Under the dragging of the bearing back seat, the outer ring of the bearing moves outward and is removed together with the bearing seat. Whether the bearing inner ring moves with the outer ring and is disassembled.
Roots blower is composed of five parts: casing, wallboard, impeller, oil tank and muffler. Casing: mainly used for supporting (wallboard, impeller, muffler) and fixing. Wall plate: mainly used to connect the casing and the impeller, support the rotation of the impeller, and play the role of end sealing. Impeller: it is the rotating part of Roots blower, which is divided into two leaves and three leaves. However, due to the advantages of three leaves, such as less air pulsation, less noise, and more stable operation than two leaves, it has gradually replaced the two leaves Roots blower. Oil tank: mainly used to store lubricating oil used to lubricate gears and bearings. Muffler: It is used to reduce the noise caused by air flow pulsation during the inlet and outlet of Roots blower.
1. Before disassembly, the assembly clearance between the disassembled parts shall be measured, and the assembly positions of key components, such as the synchronous gear of Roots blower, shall be recorded to avoid errors during reassembly.
2. The removed joint surface mat and adjusting shim shall be kept properly, their assembly position shall be recorded, and their thickness shall be measured.
3. For some components with high assembly accuracy, such as the wheel and gear ring of the synchronous gear of the blower, if the gear ring is not found damaged, do not easily remove the bolt to drive out the pin, because this assembly accuracy directly affects the clearance of various parts of Roots blower.
4. For different parts, proper tools should be selected to disassemble them so as not to damage the parts, affect the assembly quality, or even cause the Roots blower to fail to operate normally.
The difficulty in removing the gear of Roots blower lies in the synchronous gear, which is meshed by straight teeth. The driving gear is driven out by hydraulic puller, and the driven gear is driven out by its own 6 M20 bolt holes plus ejector rod. The bearing pedestal shall be ejected by the ejector rod. Pay attention to the uniform force of the ejector rod, otherwise the bearing pedestal will be damaged. The bearing pedestal shall be disassembled before installation, and then disassembled before installation. Pay attention to the clearance of each part.
I believe that after reading the above contents, you should also understand the removal and placement method of Roots blower gear. I hope it will be helpful to you.
