In global mineral exploration, hydraulic core rigs as core equipment often account for over 30% of total operating costs in maintenance. However, our research shows that more than 65% of mines still use incorrect maintenance methods, resulting in 40% shorter equipment lifespan and 50% higher repair costs. This article reveals the 3 most common fatal mistakes in daily maintenance of hydraulic core rigs and shares Hengwang Group's HW-YDX-800GL wireline core drilling rig's innovative solutions to help you save at least $150,000 annually in maintenance costs.

Mistake 1: Ignoring Hydraulic Oil Change Intervals (Affects 90% of Mines)

Typical Error: A Zambian copper mine insisted on "no alarm, no oil change," resulting in 40% reduction in main pump displacement and requiring $82,000 to replace the entire hydraulic system.

Correct daily maintenance of hydraulic core rig practices:

(1) Mandatory hydraulic oil change every 500 hours (reduced to 300 hours in extreme conditions)

(2) Use three-stage filtration system (standard on Hengwang HW-YDX-800GL)

(3) Set oil temperature alarm threshold at 65°C (typically 75°C on ordinary equipment)

Field tests by Hengwang engineers in Congo mines show strict adherence to these standards can extend hydraulic system lifespan by 3 times.

Mistake 2: Superficial Drill Rod Maintenance (Causes 60% of Downhole Accidents)

Costly Lesson: A Peruvian silver mine simply wiped drill rod threads, leading to a $230,000 downhole fracture accident.

Daily maintenance of hydraulic core rig must include:

(1) Ultrasonic flaw detection (weekly)

(2) Special grease for threaded parts (pressure resistance >8000psi)

(3) Vertical storage (to avoid stress deformation)

Hengwang HW-YDX-800GL's intelligent drill rod management system automatically records each rod's:

(1) Usage count

(2) Stress history

(3) Maintenance status

Mistake 3: Neglecting Environmental Adaptation Maintenance (Immeasurable Losses)

Lesson from Chile's Atacama Desert: Same rig models showed 78% lower failure rates when implementing environmental maintenance.

Daily maintenance of hydraulic core rig should adjust to conditions:

(1) For high humidity areas: Moisture-proof treatment for electrical systems (IP65 protection standard on HW-YDX-800GL)

(2) For extreme cold regions: Fuel heating device (-30°C cold start kit)

(3) For dusty environments: Air filter upgrade (three-stage cyclone filtration system)

(4) Hengwang HW-YDX-800GL: A Maintenance Revolution

This wireline core drilling rig redefines standards for daily maintenance of hydraulic core rig:

(1) 92kW Yuchai turbocharged engine: 50% longer maintenance intervals

(2) Smart warning system: Predicts potential failures 40 hours in advance

(3) Modular design: 70% faster hydraulic seal replacement

"After switching to HW-YDX-800GL, our monthly maintenance hours dropped from 120 to 45." - Feedback from Tanzania gold mine equipment supervisor
