How to formulate a replacement plan for vulnerable parts of mining machinery?

To formulate a replacement plan for vulnerable parts of mining machinery, it is necessary to integrate equipment operation data, working condition characteristics and intelligent monitoring technology to build a closed-loop system of "predictive maintenance + dynamic adjustment". The specific steps are as follows:

I. Core Parameter Monitoring and Threshold Setting

Youdaoplaceholder0 Vibration and temperature monitoring ‌

Gearbox: Maintenance ‌ is triggered when the effective value of vibration velocity (RMS) is greater than 8.5mm/s (with an increase of more than 30% from the baseline)

Bearing temperature: If it continuously exceeds 85℃, the lubrication system should be inspected to avoid sintering risk ‌

Youdaoplaceholder0 oil analysis ‌

Ferrography testing: Replace gears or bearings when the proportion of fatigue abrasive particles is greater than 40% ‌

Pollution control: The cleanliness of the oil should be maintained below NAS grade 8. If it exceeds the standard, change the oil immediately ‌

Iii. Dynamic Adjustment Mechanism

Youdaoplaceholder0 impact load record ‌

Record the peak value of each impact (such as torque >1.5 times the rated value) and the duration ‌

Cumulative impact exceeds 100 times per month, the cycle of the crusher plate hammer is shortened by 20%‌

Youdaoplaceholder0 environmental compensation coefficient ‌

When the dust concentration is greater than 50mg/m³, the inspection frequency of hydraulic seals is increased to twice ‌

For areas with humidity greater than 80%, the anti-corrosion coating of steel structural components should be reapplied every 6 months by ‌

V. Implement safeguard Measures

Youdaoplaceholder0 digital tool application ‌

Deploy the equipment management system: automatically record shock events and generate replacement work orders 

Handheld terminal scan code for repair: Fault response time is compressed to within 30 minutes ‌

Youdaoplaceholder0 personnel collaboration mechanism ‌

Operator: Daily inspection and record of abnormal vibration/noise ‌

Maintenance team: Analyze the oil inspection report weekly to predict the failed components ‌

Youdaoplaceholder0 Case verification ‌ : After a certain iron mine adopted this plan, the downtime rate of cone crushers decreased by 37%, and the inventory cost of spare parts was reduced by 22%‌. The dynamic adjustment mechanism can deal with variables such as hard rock working conditions, avoiding resource waste or sudden failure caused by "one-size-fits-all" replacement ‌
