BYT1‑25Z/4 Series Explosion‑Protected Electro‑Hydraulic Thruster – Flame‑Proof Safe Brake Pusher

BYT1‑25Z/4 Series Explosion‑Protected Electro‑Hydraulic Thruster 

BYT1‑25Z/4 Series Explosion‑Protected Electro‑Hydraulic Thruster is a flame‑proof hydraulic driving actuator designed for hazardous explosive working environments. When energized, the internal motor drives hydraulic assembly to push out piston rod and generate thrust to release drum brakes. When power supply cuts off, the built‑in return spring pulls the piston rod back rapidly to complete braking action.

The whole unit adopts professional explosion‑protected structural treatment, complying with explosion‑proof requirements for flammable and explosive gas‑mixed environments. It is mainly matched with drum brakes for lifting and conveying equipment in coal mines, chemical plants and petrochemical sites. It keeps stable thrust output under frequent cyclic operation, runs smoothly with low noise. Reliable sealing structure effectively prevents oil leakage and dust intrusion, adapting to complex dusty mine working conditions.

BYT1‑25Z/4 Series Explosion‑Protected Electro‑Hydraulic Thruster is a flame‑proof hydraulic driving actuator specially developed for equipment operating in explosive‑gas hazardous areas. When powered on, the built‑in explosion‑proof motor drives the internal hydraulic assembly to extend the piston rod and produce rated thrust, driving the matched drum brake linkage to release the brake for normal equipment operation. Once power is disconnected, the integrated return spring pulls the piston rod back quickly, enabling the drum brake to achieve fast and reliable parking braking.

Manufactured in strict accordance with explosion‑proof standards, the whole unit adopts professional flame‑proof enclosure structure, which effectively avoids ignition risk caused by internal electric sparks, and can work safely in flammable and explosive gas‑containing environments such as coal mines and chemical sites. It delivers stable thrust output, operates smoothly with low noise, and maintains excellent performance under frequent start‑stop cyclic working conditions. The optimized multi‑layer sealing structure prevents oil leakage and dust ingress, adapting to heavy‑dust and complex on‑site conditions of underground mines and chemical workshops.

All electrical and hydraulic key components are screened and inspected following explosion‑proof specification requirements to ensure high reliability and low failure rate. The compact structure saves installation space and supports direct assembly with matched drum brakes without complicated modification. On‑site installation, commissioning and daily inspection and oil replacement can be completed conveniently, reducing maintenance workload and equipment downtime.

As a core safety driving component for braking systems, BYT1‑25Z/4 series explosion‑protected electro‑hydraulic thruster is widely applied to cranes, electric hoists and belt conveyors in coal mines, chemical plants and other hazardous zones with explosive gas mixtures.
