"Disassembly drawing of Roots blower" and disassembly method of bearing
Roots blower is not only widely used in industry, but also widely used in aquaculture oxygen enrichment. Since it is used, maintenance and disassembly are indispensable in the process of repair and installation. If we do not understand its internal structure, the disassembly process will be very blind. Hongguang Xiaobian attached the disassembly drawing of Roots blower For your reference, you can refer to the following figure to disassemble the fan, which will directly close the point. Below the figure are several disassembly methods of the fan bearing. Please operate according to the figure and the following points. I hope you can help.
A push in method
It has the advantages of reliable operation and less damage to the machine and bearing by using the press to push the bearings of Roots blower. During disassembly, the pressing point of the press should be in the center of the shaft, and the cushion block should be close to the inner ring of the bearing.
2、 Hot disassembly method
When the bearing is disassembled by hot disassembly, the drawing tool should be installed on the bearing to be disassembled, and a certain amount of preload should be provided. Pour high temperature oil (about 100 ° C) onto the bearing repeatedly. After thermal expansion of the bearing ring, the fit clearance with the shaft is changed. If it is necessary to remove the bearing with little or little oil, the spray gun baking method can be used, but it must be noted that the temperature of the bearing should not be too high and the flame should not face the shaft, just in case. After the shaft is heated, the change of data structure will also swell, which makes it more difficult to disassemble.
3、 Pull out method
Use a two or three jaw puller to remove the bearing. The bearing is evenly loaded by pulling out. The direction and direction of the disassembly force are easy to control. It is suitable for large interference between bearing and shaft. This method is unlikely to damage parts.
There are five common disassembly methods for bearing of three blade root blower.
4、 Hydraulic method
Suitable for large size and close fit bearings. When the shaft is disassembled, hydraulic pressure should be used. The items to be disassembled by hydraulic pressure mainly include hydraulic pump, hydraulic pipe, pressure gauge and joint number, and need to cooperate to pull the horse. The pressure should be increased slowly during operation. When you hear the separation of the bearing and the shaft, use the puller and other items to remove. First of all, the pressure should be released to a high level in order to avoid injury to the equipment if the pressure has not been released to a high level.
5、 Percussion method
This is the simplest way to disassemble the bearings of Roots blower. With the help of the force of the hammer, the matched parts move and separate from each other, thus completing the disassembly. When the knock method is used to remove the bearing, the impact force should not be applied to the rolling element and bearing frame of the bearing. In general, it should be applied to the inner rings of bearings. For the purpose of disassembly.
The above is a summary made by Hongguang Xiaobian. I hope it can help you. If you don't understand, you can call us to guide the disassembly, disassembly and installation of Roots blower on site.
