Check whether the protective devices of the equipment are intact, including guardrails, protective doors, etc., to ensure that they can normally play a protective role to prevent personnel injuries and equipment damage.
Electrical inspection:
Check the appearance of the electrical lines to see if the wires are broken, aged or the insulation layer is off, especially the lines connecting motors, sensors and controllers, and replace the hidden trouble lines in time.
Check the connection of the electrical equipment, including whether the plug is firm, whether the terminal is loose, to ensure that the electrical connection is reliable, to prevent poor contact triggering electrical failure.
Second, the maintenance of mechanical components
1, into the magnet steel mechanism:
Into the magnet steel tools (such as magnet steel fixture, press fitting head):
Regularly check the wear and tear of the magnet-entering steel tools, and replace the tools with serious wear and tear in a timely manner, so as to ensure the gripping and press-fitting precision of the magnets. Prepare a certain number of spare parts according to the frequency of use and the wear rate of the tools.
Check whether the connecting parts of the magnet entry tool are loose, use the tool to tighten the connecting bolts to ensure that the tool is firmly connected.
Moving parts (guides, slides, cylinders or hydraulic cylinders):
Clean the dust, oil and foreign matter on the surface of the moving parts, add the right amount of lubricant or grease to ensure their smooth operation.
Check the wear and tear of the moving parts, such as guide rail wear, slider fit gap is too large, timely replacement of worn parts to ensure a good fit between the moving parts.
2, transmission parts:
Conveyor belt and chain:
Check the tension and wear of the conveyor belt, adjust the tensioning device when the conveyor belt is slack, and replace the conveyor belt when it is seriously worn.
Check the tension and links of the chain, lubricate the chain to prevent rust and wear; if the links are loose, deformed or badly worn, repair or replace the chain.
Gear drive (if any):
Check the wear of the gears; if the teeth are badly worn or damaged, replace the gears.
Check the installation position and meshing of gears, adjust the center distance to ensure that the gears mesh correctly and the transmission ratio is accurate.
3、Bin:
Silo structure and discharge mechanism:
Clean the residual magnets in the material bin to prevent clogging. Check the structure of the silo for deformation or damage, and adjust the tilt angle of the silo to ensure that the magnets are discharged smoothly.
Check the driving parts of the bin discharging mechanism (e.g. cylinder, electric actuator or mechanical linkage) to ensure its normal operation. Check its power supply and control signal, repair or replace the damaged parts.
4. Mechanical connecting parts:
Check whether the connecting bolts are loose or fall off, tighten the bolts regularly and use anti-loosening nuts or spring washers to prevent loosening.
Check whether the connecting parts (e.g. bracket, frame) are deformed or damaged, repair or replace them according to the degree of deformation or damage to ensure that the overall structure of the equipment is stable.
Third, the maintenance of electrical components
1, motor maintenance:
Regularly check the running status of the motor, use a multimeter, clamp ammeter and other tools to measure the voltage, current and speed of the motor to ensure that it is in the normal range.
If there is any abnormality in the motor (such as excessive current, unstable speed or overheating of the motor), further check the winding, bearing and heat dissipation system of the motor. Check the junction box of the motor to make sure the wiring is firm; clean the dust on the junction box and windings of the motor to ensure the electrical performance of the motor.
2. Sensor maintenance:
For position sensors, proximity sensors, counting sensors and other types of sensors, clean the sensing head and detection surface to avoid dust, oil and dirt affecting the sensing performance.
Regular use of test tools to check the performance of the sensor to ensure that the sensor output signal is normal. If the sensor signal abnormality or failure, according to the type of failure to repair or replace.
3、Control unit maintenance:
PLC maintenance:
Check whether the input and output signals of PLC are normal, and use PLC programming software for online monitoring to check the operation of the program.
Check the input and output modules of PLC to make sure that the modules can receive and send signals normally; if the modules are damaged, they need to be replaced. Regularly backup PLC program and parameters to prevent program loss; check the battery of PLC and replace it in time when the power is insufficient.
Controller maintenance:
Check whether the display interface of the controller displays information normally; check the display module and connecting line when display abnormality occurs.
Check whether the control parameters of the controller are correct, and make backup for the important control parameters to ensure that the parameters will not be lost or modified due to accidents.
Software Maintenance
1、Software update:
Regularly check whether there is an updated version of the software, according to the equipment manufacturer's recommendations or software update tips, update the software in time to get new features and repair known software vulnerabilities.
Before updating the software, backup the important parameters and programs of the device to ensure that the update fails to restore the original state. After updating the software, test all the equipment to ensure that the software update does not affect the normal operation of the equipment.
2、Software checking and debugging:
Regularly check the setting parameters of the software to ensure that the parameters meet the operational requirements of the equipment. For the adjustable parameters, such as into the magnet speed, magnet adsorption force, etc., check whether their settings are correct.
Test the operation of the software and check whether the software can normally receive and process the signals from the sensors and whether it can correctly send control signals to the actuator. If the software runs abnormally, check the error log and debug and modify the software.
V. Lubrication and cooling system maintenance
1, lubrication system:
Check whether the lubrication system of the equipment is working properly. For the centralized lubrication system, check the operation of the lubrication pump to ensure that it can provide lubrication for the key components on time and in quantity.
Replenish or replace the lubricant or grease according to the use of the equipment and operating time; use different lubricants for different parts to ensure that the correct lubricant is used to avoid damage to the equipment.
2. Cooling system (if any):
For the incoming magnet machine equipped with a cooling system, check whether the pipeline of the cooling system is smooth and whether the coolant is sufficient.
Check the working status of the cooling fan and cooling water pump to ensure good heat dissipation and prevent the equipment from being damaged due to overheating; regularly clean the radiator of the cooling system and clear away the scale or impurities in the cooling pipes to improve the cooling efficiency.
Sixth, regular calibration and adjustment
