BEd Series Certified Flameproof Thruster For All Flammable Gas & Coal Dust Hazardous Workshops

 

 

Core Competitive Advantages

German ED flameproof upgrade, non-immersed F-class motor core advantage (Core Highlight)

Inherit German EMG Eldro mature hydraulic structure, optimize full flameproof isolation design. Non-immersed motor structure separates windings and hydraulic oil completely, fundamentally eliminate oil corrosion motor burnout fault common in immersed BYT1 explosion thrusters; F-class high temperature insulation adapts long-time continuous high-frequency operation in underground high-temperature mine tunnels. Lightweight cast aluminum alloy flameproof housing has better heat dissipation and anti-corrosion performance than traditional cast iron BYT1, reduce overall equipment load and extend service life in humid mine environment.

Dual full-range explosion-proof certification for all hazardous scenarios

Thickened flameproof isolation enclosure completely isolate internal electric sparks, arcs and high-temperature components, prevent igniting external flammable methane, coal dust, chemical vapors and grain dust. Two standard explosion-proof grades optional for one series: ExdⅠMb dedicated for underground coal mine non-excavation working faces; ExdⅡCT4 suitable for IIA/IIB/IIC chemical flammable gas workshops, complete official explosion-proof certification documents for factory safety inspection filingJiaozuo Ci....

Built-in balance air chamber, 0–180° arbitrary multi-angle installation

Independent balance air chamber reserved on cylinder body, internal oil pressure keeps balanced no matter vertical, horizontal or inclined mounting, thoroughly solve air lock thrust attenuation fault of old explosion thrusters. Flexible multi-angle layout adapts narrow reserved installation space of underground mine conveyors and explosion-proof crane undercarriages, simplify old hazardous equipment renovation without bracket modificationZhongyuan ....

IP65 fully sealed all-weather harsh environment adaption

Whole machine adopts IP65 fully sealed flameproof junction box and waterproof cable gland, effectively block underground mine water vapor, coal dust and chemical corrosive gas invading internal electrical components, avoid short-circuit and flameproof performance failure caused by long-term dust accumulation, stable long-term operation in high-dust, high-humidity, corrosive hazardous workshops.

Passive spring fail-safe safety protection

High-strength alloy return spring installed inside cylinder body; in case of power outage, circuit short circuit or hydraulic pipeline rupture, push rod retracts instantly to clamp explosion-proof brake drum, prevent underground mine hoist load falling, conveyor material reverse sliding and explosion-proof crane trolley drifting, fully meet national mandatory safety standards for hazardous lifting machinery. Optional upper/lower travel limit switches feed brake open/closed state signals to PLC to realize full safety interlock control chain.

Ultra-low maintenance double-seal wear-resistant structure

Push rod surface hard chrome plating + double composite sealing ring, dual anti-leakage design reduce oil leakage frequency, cut regular hydraulic oil change and seal replacement maintenance cost;

All internal moving parts self-lubricated by circulating hydraulic oil, cancel manual periodic greasing work for mine maintenance staff;

Modular split cylinder body design, quick disassembly for oil change and component inspection without removing the whole thruster from brake frame;

Complete full range models BEd23/5 ~ BEd450/8 covering small to super large thrust stroke, standard universal spare parts reduce hazardous factory inventory pressure.

Diversified customized configurations

Special mining AC660V high-voltage flameproof motor optional for underground coal mine power grid; customized anti-corrosion salt-fog coating for chemical plant corrosive gas environment; explosion-proof rail clamp & wheel wind brake matching complete hydraulic power set available; vertical standard mounting bracket as default, horizontal/inclined transition brackets customizable for special equipment layout.
