YDB Explosion-Proof Oil-Cooled Electric Motorized Pulley Drum 1.5-55kW Belt Conveyor Drive Roller

YDB Explosion-Proof Oil-Cooled Electric Motorized Pulley

Product Overview

The YDB series explosion-proof oil-cooled electric motorized pulley is a specialized drive solution designed for hazardous environments requiring flameproof protection. Integrating a motor, gear reducer, and drum into a single compact unit, it delivers reliable belt conveyor drive performance in coal mines, gas chemical plants, and dust-explosive workshops. Compliant with JB/T7330-2008 and GB3836 explosion-proof standards, the YDB series ensures safe and efficient material handling in the most demanding industrial conditions.

Key Specifications

Product Features

• Fully Enclosed Explosion-Proof Housing – Isolates electric sparks completely, suitable for gas and coal dust explosion hazard environments
• Fixed-Shaft Gear Transmission – Oil-cooled heat dissipation ensures continuous heavy-load operation without overheating
• Integrated Motor + Reducer Design – Compact structure with minimal footprint, easy installation
• Customizable Configurations – Available with lagging, backstop, and braking structures for underground continuous conveying
• Reliable Sealing Structure – Dust-proof and waterproof, extended service life with easy maintenance

Applications

Underground coal mine belt conveyors, roadheader secondary transport, gas chemical plants, dust explosion-proof workshops, metal mine underground conveying, coking plant explosion-proof conveyor lines.

Installation & Operation Notes

• Installation inclination angle ≤5°, primarily horizontal positioning required; custom internal structure needed for angled applications
• Fill with XN46 oil to 1/3 of drum diameter height; replace lubricant regularly
• Wiring must be performed by certified electricians; equipment must be reliably grounded; do not pull cables during hoisting
• Run no-load test for 30 minutes without abnormal noise or temperature rise before full-load operation
• Do not convey materials exceeding 60°C; avoid corrosive liquid direct contact with drum body
• Match corresponding explosion-proof grade for underground use; do not substitute with standard pulleys

Packaging

Standard Single Unit: Solid wood base + stretch film wrapping, explosion-proof junction box with dedicated foam protection.

High-Power Models: Fully enclosed wooden crate with moisture-proof foam filling, integrated lifting lugs at base.

Accessories (backstop, lagging pads) packed in separate cartons and secured within the main crate. All packaging marked with explosion-proof labels, center of gravity, lifting points, and moisture/impact warnings.
