Эрүүний crusher холхивчийг хэрхэн тослох вэ: Бүтэлгүйтэхээс урьдчилан сэргийлэх мэргэжилтэн гарын авлага

Зөв зохисгүй тосолсон байдал нь урьдчилан сэргийлэхээс сэргийлдэг 68% -ийнхацарт бутлуур breakdowns in quarry operations. Энэхүү гарын авлага нь мэргэжлийн техникийг ашиглан эрүүний crusher-ийн хольцыг үр дүнтэй тослох, хангах 10,000+ найдвартай үйлчилгээ. We’ll cover grease selection, injection methods, and criticalpreventive maintenance strategies used by industry leaders.

Why Bearing Lubrication Matters

Jaw crusher bearings operate under extreme loads (Шалтгаална, хамаарна 200 tons force) and temperatures exceeding 80°C. Inadequate lubrication causes:

  • Premature wear (reducing lifespan by 75%)
  • Overheating failures (15% of unplanned downtime)
  • Increased energy consumption (18-25% higher)

Step-by-Step Lubrication Process

1. Select the Right Lubricant

ConditionGrease TypeViscosity
NormalLithium ComplexNLGI #2
High TempPolyureaNLGI #1.5
Wet EnvironmentCalcium SulfonateNLGI #3

2. Clean Bearing Surfaces

Use solvent flushing to remove old grease (part of routine maintenance):

  1. Disengage crusher power
  2. Remove grease fittings
  3. Flush with kerosene until runoff clears

3. Calculate Grease Quantity

G = 0.114 × D × B
Where:
G = Grams of grease
D = Bearing bore (мм)
B = Bearing width (мм)

Жишээ: 150mm bore × 75mm width = 1,282g

4. Apply Grease Correctly

Proper Injection Method:

  1. Use high-pressure grease gun (5,000-7,500 psi)
  2. Pump grease slowly until purge port showsfresh grease
  3. Rotate eccentric shaft during application for even distribution

Critical Tip: Avoid overgreasing – excess grease increases internal pressure by 30-40%, damaging seals.

5. Verify Lubrication Effectiveness

TestAcceptable RangeTool
Temperature65-75°CInfrared thermometer
Vibration＜4 mm/s RMSVibration analyzer
Grease ColorNo dark streaksClean cloth test

6. Document Maintenance Records

Track key parameters using digital maintenance logs:

Date: 2024-03-15 | Bearing: Eccentric
Grease Type: Mobilith SHC 220
Quantity: 1200g
Post-lube Temp: 68°C | Vibration: 3.2 мм / с

7. Implement Condition Monitoring

  • Weekly: Check grease consistency withstiffness test
  • Monthly: Send grease samples for lab analysis
  • Annually: Perform full bearing inspection during shutdowns

Common Lubrication Mistakes

  • Overgreasing: Causes seal damage (30% of failures)
  • Mixing Greases: Creates incompatible chemical reactions
  • Ignoring Temperature: Standard grease fails above 90°C

Advanced Monitoring Techniques

Infrared Thermography

Detect under-lubrication through temperature anomalies duringcrusher operation:

  • Normal range: 65-75°C
  • Warning threshold: >85°C

Real-Time IoT Sensors

Install smart sensors to monitor:

  • Grease film thickness (＞25μm required)
  • Bearing load distribution (±15% variance limit)
  • Lubricant oxidation levels (TAN ＜2 mg KOH/g)

Vibration Analysis

Use wireless sensors to monitor bearing condition:

Хэрэгжүүлэх Сандал: Solving Premature Bearing Failure

A granite quarry extended bearing life from 6 руу 18 months by:

  1. Installing automatic grease metering systems
  2. Implementing our 7-step protocol
  3. Training staff on proper crusher startup procedures

Essential Tools for Proper Lubrication

  • Grease compatibility chart (prevent chemical reactions)
  • Digital torque wrench for fitting installation (35-50 N·m)
  • Ultrasonic grease thickness gauge

Lubrication as Performance Strategy

Masteringhow to lubricate jaw crusher bearings reduces maintenance costs by 40% and extends component life. Remember: Effective lubrication combines proper crusher operation, quality greases, and data-driven monitoring. Implement these protocols with yourpreventive maintenance program for maximum equipment availability.
