Summary:
Oil‑line rupture is a serious malfunction in wet‑spraying rigs, which not only disrupts normal equipment operation but may also lead to safety incidents. By implementing systematic preventive measures, the risk of oil‑line rupture can be effectively mitigated, ensuring the safe and stable operation of the equipment.
I. Oil Pipe Selection and Installation Standards
Selection of tubing material
Select qualified tubing products:
1. High-pressure fuel lines shall bear a pressure‑resistance certification mark.
2. The working pressure rating shall be greater than the system’s maximum pressure. 1.5 times
3. Choose a synthetic rubber material that is wear-resistant and aging-resistant.
4. The number of steel wire braiding layers shall meet the pressure requirements.
Installation Process Control
Standard installation requirements:
Avoid excessive bending of the oil pipe; the minimum bending radius shall comply with the relevant standards.
Keep it naturally relaxed during installation to avoid twisting.
Secure with appropriate pipe clamps, with a spacing not exceeding 500mm
Avoid contact and friction with moving parts.
II. System Pressure Control
Pressure Parameter Settings
Reasonable system pressure control:
The system operating pressure shall not exceed the rated value.
The set pressure of the relief valve must be accurate.
Regular verification of the accuracy of pressure gauge readings.
Install an overpressure protection device.
Pressure Surge Prevention
Measures to reduce hydraulic shock:
1. Optimizing the opening and closing characteristics of the directional control valve
2. Install an accumulator to absorb shocks.
3. Avoid abrupt stops and starts of the actuator.
4. Properly configure the acceleration parameters.
III. Routine Inspection and Maintenance
Regular inspection system
Establish a system inspection mechanism:
Inspect the external condition of the oil lines for each shift.
Inspect the sealing of pipe joints weekly.
Monthly inspection of tubing aging conditions
Conduct stress tests on a quarterly basis.
Key Inspection Items
Special Inspection of YouTube Channel Status:
1. Inspect the surface for cracks and blisters.
2. Inspect the joint for leaks.
3. Test the flexibility of the tubing.
4. Check the reliability of the fixing device.
IV. Environmental Management for Use
Work Environment Control
Improve operating environmental conditions:
Avoid exposing the oil pipe to corrosive substances.
Maintain the working environment temperature within the permissible range.
Prevent mechanical damage to the tubing.
Avoid direct sunlight to prevent accelerated aging.
Enhanced protective measures
Additional protective devices:
Install protective sleeves on wear-prone areas.
Install thermal insulation in high-temperature areas.
Add collision protection devices.
Use flame-retardant protective materials.
V. Implementation of Operational Standards
Standard Operating Requirements
Correct operating procedure:
Avoid operating equipment beyond its rated capacity.
It is strictly prohibited to continue operations with a fault.
Pay attention to abnormal pressure fluctuations.
If any unusual noise is detected, stop the machine immediately and perform an inspection.
Emergency Response Procedure
Exception Handling:
1. Stop the machine immediately upon detecting an oil pipe anomaly.
2. Replace damaged oil hoses promptly.
3. Thoroughly clean up the leaked oil.
4. Identify the root cause of the fault and document it.
VI. Maintenance and Upkeep Management
Preventive replacement
Establish a replacement plan:
Replace regularly according to the duration of use.
Adjust the cycle based on workload intensity.
Record the usage time of each tubing string.
Establish pipeline usage records.
Maintenance Quality Control
Maintenance Process Management:
1. Use genuine or qualified replacement parts.
2. Replacement performed by qualified personnel.
3. Conduct a pressure test after replacement.
4. Maintain thorough maintenance records.
VII. Monitoring and Early Warning System
Online monitoring
Real-time monitoring system:
Install a pressure sensor for real-time monitoring.
Install a pressure anomaly alarm device.
Monitor the surface temperature of the oil tubing.
Establish early warning thresholds
Regular testing
Professional Testing Arrangements:
1. Detect using an ultrasonic flaw detector.
2. Conduct regular pressure pulse tests.
3. Conduct burst pressure testing on a sample basis.
4. Analyze trends in test data
Conclusion
Preventing hydraulic hose ruptures on wet‑spraying rigs requires systematic management across multiple stages, including equipment selection and installation, operation and maintenance, and monitoring and early warning. By establishing a comprehensive management system, strictly adhering to operating procedures, and strengthening routine inspections and upkeep, hose‑rupture incidents can be effectively mitigated. It is recommended to develop a detailed preventive‑measures manual, enhance operator training, and maintain complete equipment records to ensure that all measures are fully implemented. At the same time, emphasis should be placed on technological innovation—adopting new materials and processes—to continuously improve equipment safety and reliability, thereby providing robust assurance for long‑term, stable operation.
