Remove the outer ring of the interference fit. Set several outer ring extrusion screws on the circumference of the shell in advance, tighten the screws equally while removing fag bearing of vibrating screen. These screw holes are usually covered with blind plugs, separable fag bearings of shale shaker tapered roller fag bearings, etc., set several notches on the shoulder of the shell, use cushion blocks, disassemble with a press, or gently knock to disassemble.
The inner ring of fag bearing of vibrating screen is disassembled by oil pressure method. Oil pressure is applied through the oil hole on the shaft to make it easy to pull. The wide fag bearing is disassembled by the combination of oil pressure method and drawing fixture.
Induction heating method can be used to disassemble the inner ring of fag bearing of Nu and NJ cylindrical roller vibrating screen. It is a method of drawing after heating the part in a short time to expand the inner ring.
Check whether the cooling water pressure, water flow and pipeline system are normal. If the water pressure is low, the filter may be blocked and cannot be handled in time, the machine can be shut down for treatment. When it is confirmed that it can work, it can be put into use.
Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.
Check whether there is abnormal sound in fag bearing and whether the swing of fag bearing is abnormal.
Take an oil sample to observe whether the oil color changes, and conduct laboratory tests to see whether it deteriorates. If the deterioration is confirmed, stop the machine and replace the oil.
Check whether the oil level of the oil pointer is normal. If not, check whether the oil drain valve of the oil tank is tightly closed. If it has been closed tightly, it should be filled with oil. If it is the leakage of sealant gasket, it should be shut down for treatment.
