Project Overview
A large integrated steel mill faces heavy equipment lubrication challenges across sintering, continuous casting, hot rolling and material conveying lines. Traditional manual greasing caused uneven lubrication, frequent bearing failures, unexpected production downtime and high labor costs. High temperature, heavy dust and long-distance lubrication pipelines also made old lubrication pumps prone to air intake, grease caking and breakdowns.
Solution
The plant adopted the VDZ series electric lubrication pumps matched with dedicated intelligent control boxes for full-line centralized automatic lubrication:
1. Model Matching
- VDZ08 (8L/h, 40L tank): Auxiliary rollers & small travelling cranes
- VDZ14 (14L/h, 60L tank): Sinter machines & charging trolleys
- VDZ24 (24L/h, 100L tank): Hot rolling mills & continuous casting main drives
2. Core Advantages of VDZ Pump
- Max 45MPa working pressure with built-in 40MPa relief valve for heavy-load steel equipment protection
- Built-in agitator & scraper to homogenize NLGI 0–2 grease, avoid caking and air entrapment under high temperature
- IP55 motor, operating temperature range -20°C ~ +80°C, fits harsh steel plant environments
- 80μm filter and ultrasonic level sensor (switch/analog output) to monitor grease volume and block metal impurities
- Dual-piston pump design delivers bubble-free continuous grease supply for non-stop production
3. Intelligent Control Box Set customized lubrication cycle and operation duration freely. Receives low-grease alarm signals from the level sensor, realizes automatic operation, fault feedback and centralized monitoring for all pumps.
On-site Effect
1. Eliminated manual greasing work, reduced labor and safety hazards in high-temperature dusty zones.
2. Stable continuous grease supply cut bearing and pipeline failure rate by over 70%, greatly reduced unplanned shutdown loss.
3. Precise quantitative lubrication lowered grease consumption and waste.
4. Real-time fault & low-level early warning simplifies daily equipment maintenance.
