Summary:
When operating a mine wet-spraying carriage in low-temperature winter conditions, systematic antifreeze measures must be implemented to prevent freezing and subsequent damage to critical components such as the hydraulic system and water supply system. A scientifically sound and effective antifreeze strategy ensures the equipment can start up and operate normally under severe cold conditions, thereby avoiding equipment failure and construction interruptions.
I. Freeze Protection for Hydraulic Systems
Oil Selection and Treatment
Low-Temperature Hydraulic Oil Management:
1. Select low-temperature hydraulic oil: viscosity grade ISO VG32 or lower, with a pour point below -30 degrees Celsius
2. Oil temperature preheating control: Before startup, use the preheating device to raise the oil temperature to 10 Above ℃
3. Oil line insulation measures: Install thermal insulation blankets or electric heat tracing cables on exposed oil lines.
4. Regular oil testing: Monitor changes in oil viscosity and replace substandard oil promptly.
System Startup Preparation
Low-temperature start-up procedure:
Tiered Startup: Start with Idle Operation 5-10 minutes, then gradually increase the load.
Circulating Preheating: After startup, perform no-load operation first to ensure thorough circulation of the hydraulic fluid.
Pressure Monitoring: Closely Monitor System Pressure Build-Up
Abnormal Noise Monitoring: Pay close attention to the operating sounds of equipment, and shut down immediately upon detecting any abnormalities.
II. Protection of the Waterway System
Pipeline Freeze Protection
Comprehensive protection for the waterway system:
Drainage and Freeze Protection: Thoroughly drain all water from the pump and piping after daily operations.
Thermal Insulation Wrapping: Install insulation material on all water pipes and fittings.
Electric Heat Tracing System: Install self-regulating electric heat tracing cables in areas prone to freezing.
Antifreeze addition: Add an appropriate amount of antifreeze to the cooling water.
Pump Protection Measures
Special protection for the pump system:
1. Drain the water: After shutdown, open the drain valve to completely drain the system.
2. Seal inspection: Ensure the drain valve is tightly closed to prevent leaks.
3. Regular turning of the pump: When the pump is out of service for an extended period, manually turn the pump impeller at regular intervals.
4. Indoor storage: Disassemble the pump and store it indoors when conditions permit.
III. Electrical System Maintenance
Battery Maintenance Management
Power System Freeze Protection:
Battery insulation: Use a battery保温套 or move the battery to a warm environment.
Battery Maintenance: Ensure the battery is fully charged to prevent the electrolyte from freezing.
Wiring inspection: clean the wiring terminals and apply anti-oxidation grease.
Backup Power Supply: Prepare Emergency Startup Power Equipment
Control System Protection
Freeze Protection for Electronic Equipment:
1. Controller insulation: Yes Programmable Logic Controller , installation of thermal insulation for sensors and other equipment
2. Line inspection: Inspect cable insulation to prevent low-temperature embrittlement.
3. Interface Protection: Implement waterproof and moisture-proof measures for electrical interfaces.
4. Regular power supply: When the device is idle for an extended period, periodically power it on to dehumidify.
IV. Fuel System Protection
Diesel Antifreeze Treatment
Fuel System Antifreeze:
Choose winter diesel: use a grade of diesel that is suitable for the local lowest temperature.
Add anti-gelling agent: Add diesel anti-gelling agent in proportion to improve low-temperature flow properties.
Fuel Line Insulation: Implement insulation measures for the fuel lines.
Filter Protection: Regularly Drain Water from the Fuel Filter
Fuel System Maintenance
Special Care for the Fuel System:
1. Fuel Tank Waterproofing: Regularly inspect the fuel tank and promptly drain any water that accumulates at the bottom.
2. Pipeline inspection: Check the fuel line for leaks to prevent air ingress.
3. Preheating Device: Use a fuel preheater to raise the fuel temperature.
4. Spare fuel filter: Prepare a spare fuel filter and replace it promptly.
V. Storage and Shutdown Protection
Long-term Shutdown Protection
Winter Storage Measures:
Thorough Cleaning: Thoroughly clean all systems of the equipment before shutdown.
Complete Drainage: Drain all liquid from all pipelines.
Protective Coating: Apply rust-preventive oil to exposed metal parts.
Regular Inspections: Inspect equipment status and record findings monthly.
Temporary Shutdown Management
Short-term shutdown protection:
1. Choose a sheltered location: Park in a wind-protected, sunny spot.
2. Covered Protection: Use a rain-and-snow-proof tarp to cover the equipment.
3. Regular startup: every 3-5 Start operation today 30 minute
4. Condition Monitoring: Record Ambient Temperature During Equipment Downtime
VI. Operational Precautions
Pre-Startup Inspection
Pre-job preparation:
Comprehensive inspection: Check the status of all systems and confirm that there is no freezing.
Gradual Preheating: Gradually preheat each system in accordance with the procedures.
Trial Operation: First conduct no-load trial operation to confirm normal operation.
Emergency Plan: Prepare an emergency response plan for unexpected failures.
In-Operation Monitoring
Precautions during the assignment process:
1. Temperature Monitoring: Continuous monitoring of temperature changes across all systems.
2. Pressure Monitoring: Pay attention to fluctuations in system pressure.
3. Abnormal Sound Monitoring: Timely Detection of Unusual Sounds
4. Regular inspections: every 2 Conduct a comprehensive inspection of equipment status on an hourly basis.
VII. Emergency Response Plan
Freezing Measures
Handling procedures in case of freezing:
Thaw slowly: Use warm air or lukewarm water to thaw gradually; do not use open flame for heating.
Segmented Handling: Conduct Segmented Inspection and Treatment of Frozen Sections
Professional Repair: Contact a professional technician if severe freezing occurs.
Record Analysis: Record Freeze Status and Handling Process
Prevention and Improvement
Continuous improvement of antifreeze measures:
1. Summarizing Experience: Analyzing the Effectiveness of Antifreeze Measures
2. Refine the plan: Enhance the antifreeze plan based on actual conditions.
3. Training and Enhancement: Strengthen Training on Frost-Prevention Knowledge for Operators
4. Technical Improvements: Adopting New Technologies to Enhance Freeze Protection
Conclusion
Winter freeze protection for mine wet-spray rigs is a systematic undertaking that requires the implementation of effective measures across multiple stages, from equipment preparation and operational management to emergency response. By adopting scientifically sound freeze-protection plans and stringent management protocols, it is possible to ensure the reliable operation of equipment under severe cold conditions, thereby preventing equipment damage and construction delays. It is recommended to develop detailed freeze-protection operating procedures tailored to local climatic conditions and equipment characteristics, strengthen staff training, and maintain robust emergency preparedness, thus providing dependable assurance for winter construction operations.
