Industry Pain Points
Mine conveyors run 24/7 under heavy dust, vibration & extreme temps (-20℃~80℃), with hundreds of scattered lubrication points:
- Manual greasing causes missed lubrication, bearing seizure & unplanned downtime
- Mine sludge clogs pipelines, triggers grease leakage and fast component wear
- Frequent shutdown for manual maintenance cuts production & raises labor costs
- Uncontrolled grease waste, high spare parts replacement expenses
Our Solution Combo
VDZ Dual-Line Electric Lubrication PumpDZ Electric Pump
- Max 45MPa working pressure, 8/14/24 L/h output for long-distance conveyor lines
- 40/60/100L sealed tank with stirring scraper, works with NLGI 0#–2# grease
- IP55 motor, wide temp range -20℃~80℃, dust & mud resistant
- Ultrasonic level sensor + pressure gauge for real-time low oil/blockage alarm
Modular structure, easy cleaning & maintenance
WD-SXFL Dual-Line Reversing Valve
- Automatically switches two main pipelines for full-cycle quantitative lubrication
- All-steel anti-vibration body, anti-clog design for dusty mining sites
- Independent overpressure protection, single-line blockage won't affect the whole system
- Compact size, fits narrow installation space on conveyor racks
Working Principle
- Set lubrication cycle & grease volume via control box
- VDZ pump delivers grease; WD-SXFL valve alternately feeds two pipelines
- Distributors inject fixed grease to all roller bearings, hinges & sliding seats
- Auto stop after full cycle; real-time monitoring with fault alarm
- Fully automatic lubrication while conveyor runs - no production shutdown
On-Site Benefits
- Cut lubrication labor cost by 90%, eliminate high-altitude manual greasing safety risks
- Boost equipment operation rate by 13%, reduce bearing failure downtime by 80%
- Save 32% grease consumption via precise quantitative oil supply
- Extend roller & bearing service life by 50%, lower spare parts stock pressure
- Stable operation under harsh mine dust, low & high temperature conditions
Applicable Equipment
Open-pit & underground mine belt conveyors, processing plant feed/discharge conveyors, stacker-reclaimers, conveyor tensioner assemblies
