Core Advantages & Design Features
Multi-Protection Safety System
Zero-compromise safety standards are essential to your business. The reinforced flameproof enclosures in our explosion-proof vibration motor prevent internal explosions from spreading flames. Extreme pressure is withstood by the thick-walled shell without compromising its structural integrity.
PTC/PT100 sensors that continuously check temperature are part of thermal protection. Prior to key thresholds being achieved, you will receive early alerts. By doing this, catastrophic breakdowns during prolonged operations are avoided.
Continuous 24-hour operation generates significant thermal stress. Our motors feature optimized ventilation channels and specialized cooling fins. This engineering approach maintains surface temperatures well below the T4 rating of 135°C.
The anti-corrosive coating protects against harsh drilling site atmospheres. You won't face premature degradation from chemical exposure or moisture ingress.
The dual-eccentric weight configuration provides unmatched control over excitation patterns. You can fine-tune amplitude and frequency to match your shale shaker's throughput requirements. This precision eliminates common issues like "bridging" in material flow.
Maintenance intervals are shortened by high-strength bearings rated for continuous heavy-duty cycles. Maintaining optimal performance over long deployment times requires proper lubrication every 2,000–4,000 hours.
Your drilling rigs require reliable power sources for mud separation equipment. Our motors integrate seamlessly with ZJ90, ZJ70, ZJ50, and smaller rig configurations. They power shale shakers processing drilling fluid returns in Zone 1 and Zone 2 hazardous areas.
The stable excitation force maintains consistent screening performance despite fluctuating mud weights. You'll achieve superior solids removal efficiency during high-volume circulation phases.
Methane-rich environments demand dI or dIIB certified equipment. Our Explosion-proof Vibration Motor units drive heavy-duty feeders and conveyors where combustible dust concentrations peak. The motors prevent ignition sources while maintaining amplitude under extreme pressure variations.
Volatile hydrocarbon atmospheres require equipment that eliminates sparking risks. You'll deploy our motors on vibrating separators processing catalyst particles and chemical feedstocks. The IP65 rating prevents dust ingress that could compromise internal components.
We understand your project budgets and performance expectations vary significantly. You can select from premium Chinese motor brands or renowned international manufacturers. This flexibility ensures compatibility with existing equipment infrastructure.
Our technical team assists with brand comparisons based on your operational environment. Whether you prioritize cost efficiency or maximum reliability, we configure solutions matching your requirements.
Different drilling sites operate on varied electrical systems. We customize motor voltage from 220V to 480V single or three-phase configurations. Power ratings scale from fractional to multi-kilowatt outputs depending on your screening equipment dimensions.
Variable Frequency Drive (VFD) compatible models allow speed modulation. This feature optimizes energy consumption during low-throughput periods while maintaining full capacity when needed.
Mounting configurations adapt to your existing shaker frames and conveyor structures. We provide custom flange dimensions, shaft extensions, and connection hardware. Installation integrates smoothly without extensive modifications to your current setup.
Your operations across multiple jurisdictions require diverse compliance documentation. We supply motors certified under CE, UL, CSA, ATEX, and IECEx standards. This comprehensive certification portfolio ensures compliant operation in North American, European, and Asian markets.
Each unit undergoes rigorous factory testing including explosion containment verification. Test reports accompany shipments providing traceability for your safety audits.
Strict quality gates are used at every assembly stage in our ISO-certified production plant. Individual inspections are performed for electrical insulation, eccentric weight balancing, and bearing clearances. Equipment that satisfies published standards is delivered to you without any field modifications.
Explosion-proof motor assembly lines are maintained at the 6,300-square-meter production facility in Xingping City. Contamination that can jeopardize safety ratings is avoided in controlled environment production.
Manufacturing flaws and component failures are covered by a one-year comprehensive guarantee. To reduce downtime, replacement components will be sent to you via expedited shipment. Our technical support staff offers both on-site commissioning support and remote troubleshooting.
Component schematics, torque standards, and maintenance schedules are all included in comprehensive documentation packages. Training programs give your maintenance staff the skills they need to properly service flameproof equipment.
Logistics & Delivery ExcellenceRapid Fulfillment Timelines

Reliable delivery to remote drilling areas is ensured by strategic alliances with logistical companies. International shipping are streamlined by easy access to Shanghai and Tianjin ports. Throughout the transit procedure, you will receive detailed tracking information.
For big machinery, protective packaging satisfies international shipping requirements. The motors are delivered undamaged and ready for installation.
Q: What differentiates Ex d IIB T4 from Ex d IIC T4 ratings?
A: The IIC classification covers more volatile gases including hydrogen and acetylene. An IIC-rated motor can substitute for IIB applications, but IIB units cannot replace IIC requirements. Your gas atmosphere analysis determines the appropriate rating.
Q: How do I determine the correct excitation force for my shale shaker?
A: Excitation force correlates with screen surface area and material throughput. Generally, 3-5 times the vibrating mass provides effective screening. Our engineers calculate optimal force based on your equipment specifications and drilling fluid properties.
Q: Can I use these motors with Variable Frequency Drives?
A: Yes, when specified with VFD compatibility. Motors include thermal monitoring sensors (PTC or PT100) essential for operation at reduced speeds. VFD use requires proper cable shielding to maintain explosion-proof integrity.
Q: What causes bearing failure in vibration motors?
A: Insufficient lubrication accounts for 60% of bearing failures. Use high-temperature, anti-wear grease suitable for flameproof seal compatibility. Contamination from inadequate IP rating maintenance causes additional failures. Proper mounting prevents misalignment stress.
Q: Why does the motor housing feel excessively thick compared to standard motors?
A: The reinforced casing must contain internal explosions without structural failure. Wall thickness calculations account for maximum explosion pressure of the rated gas group. This safety feature prevents flame propagation to external atmospheres.
Q: Does vibration force decrease over operational time?
A: Properly secured eccentric blocks maintain consistent force output. Perceived force reduction typically results from loose mounting bolts or structural fatigue in supporting equipment. Regular torque verification prevents these issues.
Q: What maintenance intervals should I follow?
A: Bearing lubrication every 2,000-4,000 operating hours depending on duty cycle intensity. Inspect mounting bolt torque monthly. Annual electrical insulation testing verifies continued explosion-proof integrity. Replace seals every 12,000 hours or per manufacturer specifications.
