Technical Principle

The core working principle of gas and dust dual explosion-proof control motors is based on isolated explosion-proof structure design, which completely isolates internal arcs, sparks and high temperatures generated by the motor from external hazardous media, while preventing dust intrusion through sealed structures. The complete implementation logic chain is as follows: 1. Explosion isolation: The high-strength shell withstands internal explosion pressure without rupture, and prevents flame propagation to the external environment.
2. Sealing protection: The sealed structure and explosion-proof cable gland block combustible dust from entering the motor interior, avoiding dust accumulation and ignition risks.
3. Integrated drive control: The integrated motor-controller-driver design reduces external connection points, lowering the risk of wiring failure.

Core architecture and innovative design: 1. Explosion isolation shell: Made of high-strength aluminum alloy or cast iron, with pressure resistance and flame retardant performance, improving overall structural reliability.
2. Integrated drive control module: Integrates motor, controller and driver in the same shell, reducing installation space by 40% and simplifying system maintenance.
3. Sealing and anti-vibration structure: Equipped with standard explosion-proof cable gland, with no displacement or sealing failure under cable tension ≥100N, and can withstand 10g peak acceleration, adapting to drilling impact working conditions.

Compared with traditional split-type explosion-proof control motors, our technology has achieved core breakthroughs: 1. Traditional split-type design requires complex external wiring, large installation space and high on-site debugging cost. Our integrated design reduces wiring complexity, cuts on-site debugging labor cost by 60% and shortens project acceptance cycle.
2. Traditional motors have an anti-vibration limit of 5g, with high cable disconnection rate. Our anti-vibration performance reaches 10g peak acceleration, reducing cable disconnection rate by 90%.
