Introduction: Why Maintenance Is the Key to the Longevity of Breaker Hammers?
For foreign contractors and mining operators, the hydraulic breaker is an important investment. The costs of maintenance and replacement of parts are high, and the procurement process is lengthy. However, many equipment failures are not due to design flaws, but rather result from inadequate daily maintenance. Piston rust, premature wear of seals, loose bolts not being addressed in time – these seemingly minor issues can eventually escalate into thousands of dollars in repair bills and weeks of downtime losses.
This article will systematically introduce the key points of daily maintenance and the periodic maintenance plan for interrupteurs hydrauliques, helping you achieve the most long-lasting and reliable operation of the equipment with the minimum daily investment.
Daily Maintenance: 10 minutes per day, avoiding major problems
Butter Addition – The Most Basic and Crucial Protection
The function of grease is not only to lubricate, but also to form a protective film between the chisel and the inner and outer sleeves, significantly reducing wear.
- Operation timing: It must be refilled once before starting work each day; then, refill every 2 hours of work.
- Operation points: Place the breaker hammer upright, press the chiselvertically into the ground, and then add approximately 50 milliliters through the grease nozzle. The purpose of pressing down the chisel is to make the dust seal contract, ensuring that the grease enters the internal slide groove instead of being squeezed out or entering the piston chamber.
- Common misunderstandings among foreign customers: Some operators try to save time and add grease without pressing down the chisel, resulting in the grease only remaining on the outside of the dust seal, unable to truly lubricate the inner and outer sleeves, causing early wear.
Bolt Tightening Inspection – Preventing Minor Loose Connections from Causing Major Accidents
Le breaker hammer operates under high-frequency vibration, and there is a possibility that the connecting bolts of the housing may become loose.
- Inspection frequency: Before starting work each day, visually inspect all bolts to check for any signs of loosening.
- Handling method: Use the dedicated wrench provided in the toolbox to tighten them according to the specified torque.
- Risk reminder: If the loose bolts are not tightened in time, it may cause the shell to crack or the internal mechanism to shift. The repair cost will be much higher than the small investment for daily inspections.
Inspection of chiesel et pin of chisel – Eliminate the risk of fracture
- Inspection items: Visual inspection of the chiselfor any cracks, abnormal wear or deformation; Inspection of the pin (cross pin) of the chisel for any signs of fracture.
- Handling method: If any fracture or severe wear is found, it should be replaced immediately; do not use it as a makeshift solution.
- Risk reminder: The fractured pin of the chiselmay cause the chisel to come off during operation, resulting in a serious safety accident.
Nitrogen Pressure Measurement – Ensuring the Benchmark for Impact Force
- Check frequency: It is recommended to check the nitrogen pressure in the cylinder body once a week.
- Adjustment method: Use the dedicated nitrogen pressure gauge in the toolbox for testing. If the pressure is higher than the standard value, release the excess nitrogen; if it is lower than the standard value, replenish it to the specified value.
- Key principle: Excessive pressure will cause the piston to have difficulty moving back and the strike to be weak; insufficient pressure will result in insufficient explosive force. Maintaining the standard value is the prerequisite for stable strike force.
Periodic Maintenance: Schedule for Regular Replacement of Seals
Les composants d'étanchéité sont les pièces clés qui empêchent les fuites d'huile hydraulique et maintiennent la pression du système. À mesure que le temps d'utilisation augmente, ces composants d'étanchéité vieilliront naturellement et s'usureront.
Replacement Cycle Based on ciselle Diamètre
| Crusher Specifications | ciselle Diamètre | Suggested Replacement Period for Sealing Parts | Special Notes |
| Small Model | ≤100 mm | Every 6,000 – 8,000 hours | If there is oil leakage in advance, it must be replaced immediately |
| Medium Model | 100 – 165 mm | Every 4,000 – 6,000 hours | The higher the quality of the sealing parts, the longer the period can be |
| Large Model | ≥165 mm | Every 3,000 – 5,000 hours | In high-load working conditions, a shorter period should be adopted |
Oil Leakage – Clear Signal for Early Replacement
Regardless of whether the planned replacement time has been reached or not, once it is discovered that the breaker hammer is leaking hydraulic oil, the sealing parts should be replaced immediately. Delaying the handling not only wastes the hydraulic oil but also may cause the piston and cylinder to be severely scratched due to insufficient lubrication, resulting in even greater repair losses.
The Maintenance Advantages of METDEEM
The lifespan of the sealing piece is not only determined by the rubber material itself, but also by the surface quality of the metal component it is in contact with.
- High-precision polishing technology: During the production process, METDEEMperforms high-precision polishing on all components in contact with the sealing parts,such as pistons, inner walls of the cylinder, ensuring that the surface finish exceeds industry standards.
- Significant reduction in friction: The smooth surface significantly reduces the friction resistance of the sealing parts during reciprocating motion, delaying the rubber wear.
- 20% extension of maintenance cycle: Thanks to this technology, the replacement cycle of the sealing parts of METDEEM crushers can be extended by approximately 20% compared to similar products, directly saving users long-term maintenance costs.
Conclusion
The maintenance of the breaker is not complicated. The key lies in consistency and standardization. Daily tasks such as adding grease, checking bolts, inspecting the chisel and nitrogen gas, along with the planned replacement of seals, these seemingly simple operations are the foundation for ensuring the equipment operates efficiently for a long time. METDEEM further reduces the maintenance frequency and cost for users through precise processing techniques, allowing you to spend more time on value-creating operations.
FAQ (questions fréquentes)s
Q: If you only worked for 1 hour on that day, do you still need to add grease?
A: Yes. The time interval for adding butter should be based on the number of working hours. Even if it’s less than 2 hours, you must add it again before the next day’s work because the grease left over from the previous night will harden or be lost.
Q: When checking the nitrogen pressure, it was found to be too low. Can it be replenished directly?
A: Yes, but it is recommended to first check for any leakage points. If the pressure is consistently low, it may indicate that the sealing parts have been damaged. In such cases, the equipment should be repaired before replenishing the pressure.
Q:The replacement cycle for the seals has arrived, but the equipment is operating well. Can we postpone the replacement?
A: It is not recommended. The aging of the seals is a gradual process. Even if they are functioning normally at present, they may suddenly fail under high-load operations, causing oil leakage and damage to components. Replacing them according to the schedule is a more economical option.
