1.Specialized person should responsible for the equipment during the machine running. The operator should be technically trained with full knowledge of the machine, and should also familiar with operation rules.
2.In order to ensure normal work of the machine, the safe operation system of equipment maintenance should be formulated to guarantee the long-term, safe and reliable operation. Meanwhile, the necessary maintenance tools, spare parts and lubricating oil must be provided.
3.The fastener should be checked during each shift, if finding any part loosened, fasten it timely.
4.The equipment should be checked periodically through checking door to inspect every inner worn parts such as rings, liners, guard plate around and wear-resistant parts in the flow passage of throwing wheel. If found any parts worn, should be repaired or changed immediately. If the wear-resistant parts is worn, the whole set of them should be changed to ensure the throw wheel in balance. If the throw wheel found worn, it should be repaired or changed.
5.The fastening parts of throwing wheel should be checked every 7 days, if found any parts worn, replace or repair them at once.
6.The fastening parts and tear-wear parts of vortex cavity should be checked once half a month. If anything abnormal, eliminate immediately.
7.Oil lubrication is 32#(Minimum temperature lower than 15℃) or 46#(Minimum temperature higher than 15℃) antiwear hydraulic oil 150-190L. The first 1000 hour working makes the oil change. Afterwards, 2500-3000 hours change the oil in regular working. The pipes should be disassembled when replacing the oil, the connecting oil pipes should be cleaned and dry, and worn seal pad should be replaced.
8.Adjust the tensile force of transmitting V belt appropriately, so that to guarantee the V belt is under even stress. The unbalanced current of the motors in two sides should not exceed 15A. 9.Check lubrication pressure system frequently, and anything abnormal should be repaired at once.
10.The calcium-based grease should be filled in the seal ring under the bearing cabinet with cover-rotating type oil cup installed under the bearing barrel when stopping the machine.
11.The bearing barrel should be disassembled and cleaned after 1000 hours of normal operation for the first time. Afterwards, 2500-3000 hours change the oil in regular working.
