OTO Pulley type wire drawing machine
The first Safety precautions for LZ600 wire drawing machine
1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.
1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.
1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.
1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.
1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.
1. 6 Before starting the machine, check whether the safety device is normal.
1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.
1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.
1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.
The second Delivery inspection
2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.
2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.
2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use

The inner and outer rings of the bearing are separated, and the center of the thrust can be well centered after assembly, while the side thrust is very poor in centering effect, which is greatly affected by the technical level of the assembly workers. The larger the axial amount, the worse the centering effect is. The small amount of the string causes the bearing to overheat, and the precision of the domestically produced thrust bearing is poor. There is no regulation on how long it takes to re-adjust the amount of resources. If the axial string is too large, the axis is not well positioned. At the same time, the unit is vibrating in the reciprocating machine. When the amplitude reaches a certain value, it may impact the broken teeth.
The coupling diaphragm is under compression, and the axial thrust of the high-speed shaft of the reduction box happens to be pushed to the coupling, so that the axial thrust is received by the coupling diaphragm, and the thrust bearing is very small, even It does not withstand axial forces, so the centering effect at the high speed shaft coupling is extremely poor. When the coupling is installed, it is allowed to have a different center of 011mm. Here, the vibration source of the gearbox is generated. From the perspective of gear damage for many years, it has also been proved that the gears are dismantled on the side of the large gear compressor. Before the transformation, the couplings are hammered down by hand and the installation clearance is negative.
When the reducer is rebuilt, we consider the stock spare parts, and the size coordination is more on the retaining ring and the bearing gland to ensure that the spare parts can still be used. After the gear is dismantled, it should be analyzed comprehensively. It should not be used to find the cause of the problem. Especially at this stage, the imported equipment spare parts mainly rely on domestic production, which may cause problems due to the quality of other spare parts. Therefore, it is very important and necessary for the on-site maintenance personnel to correctly determine the cause of the failure and take corresponding measures.
