HSD Marine Piston Electric Horn

HSD marine piston electric horn is based on traditional fog horn technology, absorbs international advanced design concepts and integrates advanced production technology, makes many innovations in structure and principle, scientifically integrates air compressor, air storage tank and pipeline, and combines with modern microcomputer advanced technology. This new series of products well solves the problems of traditional marine horn equipment in terms of installation, use and maintenance, saves more space for ship equipment, and is an ideal modern marine horn.

Overview

Application

Suitable for large and medium ships with a length of more than 75m and offshore work platforms.
Suitable for other factories, mines and special places, replacing traditional whistles.

Main components

Sound system: It is composed of motor, driven gear, eccentric shaft, piston, piston cylinder, sound body (sound diaphragm), resonator, speaker and other parts.
The automatic control system is mainly composed of microcomputer with single chip microcomputer as the core.

Key points of technical innovation

Using the motor as the motive force, through the gear transmission, the eccentric shaft rotates at high speed, driving the piston to reciprocate at high speed in the piston cylinder, compressing the air in the sound cavity to produce the whistle.
Using microcomputer single-chip control technology to realize human-machine dialogue, it can send out fog horn signals with different coded information in accordance with the requirements of international conventions and regulations in a timely and automatic manner according to the actual environmental needs of the ship.
Creative use of spiral sealing grease technology not only ensures the seal, but also ensures that the main components are effectively lubricated, greatly extending the service life of the horn.
The piston cylinder is integrated with a soft heater made of special materials to ensure that the piston cylinder works reliably. It has the characteristics of corrosion resistance, fast heating, and temperature controllable, ensuring that the piston cylinder can work normally in severe cold environments, and the heating source can be obtained in daily production activities, which is both environmentally friendly and energy-saving.
The air compressor, air storage tank and pipeline are integrated to solve the problems of easy leakage and pipeline blockage of traditional marine horn air storage tanks. And no air compression equipment is required, which not only reduces energy consumption, but also eliminates the loss in the storage, transportation and conversion process, making the product more energy-saving and environmentally friendly.
