The Electric Piston Horn is a new type of horn with a more reasonable structure, Reliable quality, simple operation, no need for compressed air, saving cost. Electric Piston Horn BZHSD-90 and BZHSD-161 suitable for all kinds of large and medium-sized ships and vessels (longer than 75 meters) with three-phase electricity.

What is an electric piston horn

The electric piston horn is based on traditional fog horn technology. Absorb international advanced design concepts and advanced production technology, carry out many innovations in structure and principle, and scientifically combine air compressors, gas storage tanks, and pipelines. The successfully developed new fog navigation equipment combined with modern microcomputer advanced technology realizes automation and intelligent control, and completely eliminates the defects of traditional fog navigation horns in high-power air compressors, large-capacity gas storage devices and complex pipelines. It solves the problems of equipment installation, use, maintenance, etc., so that the ship has a broader design space, construction space and use space. It is currently the most ideal modern marine fog navigation equipment, and an upgraded product of the “Air horn”.

Main components

The marine electric piston horn consists of a sound system and a direction control system. The sound system is mainly composed of a motor, a driven gear, an eccentric shaft, a piston, a piston cylinder, a sounding diaphragm, a resonator, and a horn. Through mechanical connection, each component becomes a unified whole with independent functions.

Working principle

Through the “Fog Aviation Automatic Control System” with the “Single Chip Microcomputer” as the core, human-machine dialogue is realized. The system automatically outputs a “signal” according to the set “actual environment”, drives the relay, connects the main power supply to the motor, and drives the motor to run. The sound system is powered by a motor, which drives the eccentric shaft to rotate at a high speed through the teeth. The eccentric shaft drives the piston to make high-frequency reciprocating motion in the piston cylinder, compresses the air in the compression chamber composed of the piston and the piston cylinder, and drives the sounding diaphragm to sound. Through the resonance of the resonator, the horn sends out a corresponding “fog” signal.

Innovation and advantages

Motor-Powered Operation

The electric piston horn utilizes a motor-driven eccentric shaft to achieve rapid reciprocation of the piston in the cylinder, generating a signal sound by compressing air in the sound cavity. Our company is proficient in this technology, enabling the in-house production of electric piston horns and various models.

Advanced Control Technology

Employing microcomputer “single-chip” control technology enables intelligent man-machine dialogue. The system automatically emits coded “fog” signals, meeting IMO requirements based on the ship’s environment. The overall implementation of automatic intelligent control is globally recognized as a pioneering achievement.

Spiral-Wound Sealing Grease Technology

Incorporating innovative “spiral-wound sealing grease technology” ensures effective sealing and lubrication of main components, addressing wear issues seen in other accessories and extending the lifespan to match that of the ship.

Specialized Heater for Piston Cylinder

The integration of a soft heater, made of special materials, into the piston cylinder ensures reliable operation, even in severe cold conditions. With features like corrosion resistance, fast heating, and temperature control, it provides an environmentally friendly and energy-saving solution for daily production activities.

Integrated Design for Efficiency

The piston cylinder integrates an air compressor, gas storage tank, and pipeline, eliminating traditional fog horn drawbacks. This integration offers several advantages:

Cost Efficiency

Reduction in raw material and manufacturing costs.

Problem Resolution

Elimination of issues like gas storage tank leakage and pipeline blockage, saving resources.

Energy-Saving Design

The electric piston fog horn reduces energy consumption by operating the motor only when sound is required. It eliminates the need for continuous operation of high-power air compression equipment, making it more energy-efficient and environmentally friendly.

Space Optimization

Saves installation space, contributing to more rational and flexible ship design. This fosters advancements in ship design, manufacturing, and construction, elevating the overall technical standard of ships.
