Manhart How to determine whether the operation status of the rolling machine is normal?

To determine whether the running status of the rolling machine is normal, the following steps and key points can be followed for judgment:
1. * * Noise inspection * *:
-When the rolling machine is idling, the noise pressure level shall not exceed 90dB.
-During the operation of gear transmission, electrical, and hydraulic components, there should be no irregular impact sounds or periodic screams.
2. * * Mechanical transmission system inspection * *:
-The mechanical transmission system should operate normally, smoothly, and without any abnormal sounds.
-The braking should be sensitive and reliable.
3. * * Hydraulic system inspection * *:
-Hydraulic components and pipelines must not have any leakage.
-The oil temperature inside the fuel tank should generally not exceed 50 degrees during the operation of the rolling machine.
-After working continuously at full load for 4 hours, the oil temperature in the tank shall not exceed 60 degrees.
-Hydraulic transmission components should not experience vibration crawling, stagnation, or significant impact within their working range.
-The amplitude of idling should generally not exceed 30 μ m.
4. * * Motor inspection * *:
-Pay attention to whether the running sound of the motor is normal.
-With the help of auxiliary tools such as screwdrivers or listening sticks, stick the two ends of the motor to listen and check for any adverse vibrations or the amount of bearing oil.
5. * * Other precautions * *:
-The reasons for the heating of the plate rolling machine may include: excessive pressure regulation, poor heat dissipation conditions due to the small oil tank of the plate rolling machine, excessive axial clearance, or internal leakage caused by damaged sealing rings.
-For rolling machines that use open bearings, special bearing oil should be used when refueling to avoid affecting the heat dissipation function of the motor.
By examining the above steps and key points, it is possible to comprehensively determine whether the running status of the rolling machine is normal. In daily operations, it is recommended that operators strictly follow safety operating procedures to ensure the safe and stable operation of the equipment.
