Compound cone crusher is a commonly used mining crushing equipment, widely used in mining, metallurgy, chemical industry and other industries. Cone crusher has a bad use environment, a lot of dust, and some users do not maintain it properly, so the quality requirements of accessories are high. Copper sleeve is an important part of cone crusher, such as eccentric shaft copper sleeve, moving cone copper sleeve and horizontal shaft copper sleeve, which play a very important role in the operation of the equipment. Now, Xin Gaonai Heavy Industry will explain the replacement method of cone crusher copper sleeve.
First, you need to prepare some tools and materials, such as wrenches, oil extractors, oil dipsticks, disassembly and assembly kits, etc. You need to turn off the power of the machine, remove the parts near the part to be replaced, and expose the copper sleeve. Next, use the appropriate tool to gently take out the copper sleeve.
How to replace the eccentric copper sleeve: Turn the eccentric sleeve upside down to take out the copper sleeve. Before installing the eccentric sleeve copper sleeve, check whether there are any broken marks on the inner hole of the eccentric sleeve, whether the surface is clean, and whether the size is accurate. If there are special circumstances, they should be handled in time. When installing the eccentric shaft copper sleeve, dry ice can be used for cooling. When pouring the locking packing, the eccentric sleeve and the copper sleeve must be placed at a temperature of about 70 degrees, and the oil holes of the eccentric sleeve and the copper sleeve must be aligned.
Replacement method of the copper sleeve of the moving cone: The copper sleeve under the moving cone can be sawed off, but make sure not to damage the inner hole of the moving cone. The copper sleeve on the moving cone can be pulled out directly, and can be cooled with dry ice to speed up the pulling out. During installation, the copper sleeve of the moving cone can be cooled with dry ice for at least 2 hours. When it is fully cooled, the copper sleeve is lifted with its lifting ring. A flat gasket should be used under the lifting ring to ensure that the edge of the copper sleeve is parallel to the bottom edge of the moving cone.
Replacement method of the copper sleeve of the horizontal shaft: The outer copper sleeve can be removed by a homemade pulling device, and the inner copper sleeve can be removed by hammering with a center rod device. After the copper sleeve is removed, it is necessary to check whether the inner hole size of the shaft frame is reasonable. When installing the copper sleeve of the horizontal shaft, dry ice shrinkage should be used for at least 2 hours.
Finally, after the copper sleeve is installed, it must be ensured that it cooperates well with other parts and is stable and firm. The machine can be reassembled and the previously removed parts can be reinstalled. Turn on the power, start the machine, and check whether the copper sleeve is installed normally and whether it runs smoothly.
In short, the replacement of the copper sleeve of the cone machine needs to be operated with caution, and it must be done when the power of the machine is turned off. New Gaonai Heavy Industry introduces the detailed steps for replacing the copper sleeve of the cone machine, hoping to help friends who need to replace the copper sleeve.
