The efficient operation of the quartz sand production line relies on regular
maintenance and preventive maintenance measures. These measures aim to reduce
equipment failures, extend service life, improve production efficiency, and
ensure the stability of product quality. The following are detailed measures for
regular and preventive maintenance:
1、 Regular maintenance measures
1. Equipment inspection
Inspection content:
Whether the appearance and connecting components of each device are firm.
Are there any abnormalities in the motor, cables, and control panel.
Is the tension of the belt drive system appropriate, and are there any signs
of wear or cracks.
Whether the lubrication points are lacking oil, and whether the oil quantity
and quality of each lubrication system are normal.
Is the wear level of the sieve, crusher, and magnetic separator within the
normal range.
Frequency: Daily or weekly inspections, monthly and quarterly in-depth
inspections.
2. Cleaning equipment
Objective: To remove dust and debris from the surface and operating parts of
the equipment.
Key cleaning areas:
Vibration screen: Clean the blockages on the screen to ensure screening
efficiency.
Crusher: Clean the accumulated material at the feeding and discharging ports
to avoid blockage.
Magnetic separator: Regularly clean the magnetic roller and magnetic
separation tank to prevent the accumulation of iron impurities from affecting
the sorting effect.
3. Replace vulnerable parts
Vulnerable parts: sieve, crusher hammer, mill liner, conveyor belt, bearings,
etc.
Frequency: Replacement is carried out based on the running time and actual
wear and tear of the equipment, usually checked once every quarter.
4. Check the lubrication system
Content:
Regularly replace lubricating oil or grease and check if the lubrication
pipeline is unobstructed.
Key lubrication points: bearings, reducers, and transmission gears.
Frequency: Check the lubrication system monthly and replace the lubricating
oil every six months.
5. Electrical system maintenance
Inspection content:
Whether the cable line is aging or damaged.
Is the wiring loose and is the control panel functioning properly.
Is the operating current and voltage of the motor within the standard
range.
Frequency: Check the electrical system once a month and conduct in-depth
inspections every quarter.
2、 Preventive maintenance measures
1. Develop a maintenance plan
Develop annual, quarterly, and monthly maintenance plans that cover
inspection, maintenance, and replacement items.
Ensure that maintenance plans are coordinated with production schedules and
minimize downtime as much as possible.
2. Vibration analysis and monitoring
Method: Use online monitoring equipment or handheld vibration detectors to
monitor the vibration status of the equipment in real time.
Objective: To identify abnormal vibrations and promptly investigate issues
such as bearing damage, imbalance, and looseness.
3. Regularly calibrate equipment
Calibration equipment: including automation control systems, sensors, and
measuring devices.
Goal: Ensure the accuracy of data collection and control.
Frequency: Calibration should be conducted every six months or once a
year.
4. Temperature and noise monitoring
Content: Monitor the temperature of motors, bearings, lubrication systems,
and equipment operating noise.
Objective: To detect potential faults in advance through temperature rise and
abnormal noise.
Measure: Install online monitoring instruments to achieve real-time
alarm.
5. Reserve key spare parts
Content:
Reserve key components of equipment (screens, bearings, gears, belts,
etc.).
High quality products should be selected as key spare parts to ensure their
availability for emergency replacement.
Objective: To avoid prolonged downtime caused by missing spare parts.
6. Employee skills training
Regularly conduct maintenance skills and operation training to enhance
employees' ability to maintain and upkeep equipment.
Key training content:
Equipment operating principle.
Fault diagnosis methods.
Safety operating procedures.
7. Environmental monitoring and improvement
Content: Ensure that the working environment of the production line is clean,
with appropriate humidity and temperature.
measures:
Equipped with dust-proof equipment to reduce the damage of dust to the
equipment.
Apply rust inhibitors or anti-corrosion coatings to areas prone to
corrosion.
Regularly clean the drainage system to prevent water accumulation from
affecting equipment.
8. Data recording and analysis
Record content: operating parameters (current, voltage, temperature,
vibration, etc.), maintenance records, fault records.
Analysis objective: To discover the trend of equipment performance decline
through data analysis and take measures in advance.
3、 Implementation effect
Through regular maintenance and preventive maintenance measures, the
following goals can be effectively achieved:
Reduce failure rate and improve equipment stability.
Extend the service life of equipment, reduce replacement frequency and
cost.
Improve production efficiency and reduce downtime.
Ensure product quality and meet market demand.
Energy conservation and consumption reduction, lowering production costs.
A comprehensive maintenance system can not only ensure the normal operation
of the quartz sand production line, but also bring long-term economic benefits
and market competitiveness to the enterprise.
