Product Description & Technical Details

Product Introduction

The YBBP series explosion-proof motors are high-performance, low-maintenance three-phase induction motors manufactured with premium electrical and mechanical materials, covering a wide power range and multiple pole/speed configurations to meet diverse industrial drive needs. This full lineup includes 2-pole high-speed models (YBBP801-2 to YBBP450L2-2), 4/6/8-pole medium-speed models, and 10/12/14/16-pole low-speed high-torque models, all featuring standardized frame sizes, interchangeable mounting dimensions, and plug-and-play installation for seamless integration with target equipment. Every motor undergoes strict explosion-proof testing, insulation performance testing, and load testing before shipment, with a 99.2% factory pass rate to ensure reliable operation in harsh hazardous environments.

Key Functional Specifications

• Explosion-Proof Performance: Adopts flameproof enclosure design with reinforced joint surfaces and sealed wiring compartments, suitable for Ex d II BT4 and Ex d II CT4 hazardous areas, effectively preventing internal sparks from igniting external flammable gases and dust.

• Energy Efficiency & Power Output: High-efficiency copper rotor design reduces energy loss by 12% compared to conventional motors; wide power range from 0.75kW to 500kW, with stable torque output across all speed levels to match varying load demands.

• Operational Stability: Low vibration design (vibration intensity ≤2.8mm/s) and low noise operation (noise level ≤75dB), with built-in thermal protection components to prevent overheating and burnout under continuous operation.

• Insulation & Durability: Class F insulation system with H-class temperature rise resistance, strong moisture and corrosion resistance, suitable for long-term operation in humid, dusty, and corrosive industrial environments.

Structural Design Features

• Reinforced Flameproof Enclosure: High-strength cast iron housing with precision-machined flameproof joints, meeting strict explosion-proof pressure resistance and sealing requirements; rugged construction resists impact and deformation.

• High-Precision Rotor & Stator: High-grade silicon steel sheet core and pure copper winding reduce magnetic flux loss and heat generation; dynamically balanced rotor minimizes vibration and extends bearing life.

• Universal Mounting Design: Standard B3 foot mounting and B5 flange mounting options, interchangeable with mainstream industrial explosion-proof motors, simplifying installation and replacement.

• High-Durability Bearings: Imported high-temperature resistant bearings with sealed lubrication, maintenance-free for up to 20,000 operating hours, reducing downtime for bearing replacement.

Applicable Operating Conditions

These YBBP series explosion-proof motors are engineered to operate reliably in the following harsh industrial conditions:

• Ambient temperature range: -20℃ to 40℃ (-4°F to 104°F), suitable for indoor and outdoor hazardous locations

• Altitude: Up to 1000 meters above sea level (customizable for higher altitudes)

• Environment: Hazardous areas with flammable gases, explosive dust, and volatile chemical vapors (petrochemical, coal mining, oil and gas, marine, chemical processing industries)

• Power supply: 380V/660V three-phase AC, 50Hz/60Hz (customizable voltage options available)

Maintenance & Service Recommendations

1. Routine Inspection Schedule: Conduct visual inspections of motor housing, wiring, and cooling fins every 30 operating days; check bearing temperature and vibration levels every 90 operating hours to detect abnormal wear.

2. Lubrication Protocols: Replenish bearing lubricating grease every 6-12 months (depending on operating load) using specified high-temperature grease; avoid over-lubrication to prevent seal damage.

3. Insulation & Sealing Checks: Test motor insulation resistance every 6 months to ensure it meets safety standards; inspect flameproof joint surfaces for damage or dust buildup, and clean regularly to maintain explosion-proof performance.

4. Load & Temperature Monitoring: Avoid overloading the motor beyond rated power; monitor winding temperature during operation, and shut down immediately if overheating occurs to prevent insulation burnout.

5. Storage Guidelines: Store unused motors in a dry, ventilated environment with humidity ≤65%; cover wiring terminals and shaft ends to prevent dust and moisture ingress.

Field Failure Repair Cases (Real-World Industrial Scenarios)

We supply the following spare parts:

Case 1: Petrochemical Pump Motor Overheating & Insulation Failure

A petrochemical plant’s YBBP160M-4 motor driving a feed pump experienced frequent overheating and insulation degradation, leading to automatic shutdowns. Technicians found clogged cooling fins and degraded bearing lubrication. Cleaning the cooling system, replacing the bearings, and refreshing the winding insulation restored normal operation, with temperature rise reduced by 28% under full load.

Case 2: Mining Conveyor Motor Bearing Vibration Failure

A coal mining facility’s YBBP280M-6 motor for a belt conveyor suffered severe vibration and abnormal noise, halting material transport. Inspection revealed worn bearings and an unbalanced rotor due to dust accumulation. Replacing the bearings, dynamically balancing the rotor, and installing a dust cover eliminated vibration, resuming continuous conveyor operation.

Case 3: Chemical Fan Motor Wiring Seal Leakage

A chemical plant’s YBBP132S1-2 motor for an exhaust fan had damaged wiring compartment seals, allowing corrosive vapor ingress and causing short-circuit risks. Replacing the sealing gaskets, rewiring the terminal block, and resealing the enclosure restored explosion-proof and insulation performance, ensuring safe operation in corrosive hazardous conditions.
