Marine Air Horn

Marine Air Horn

Description：

Marine air horn is a type of whistle device that uses compressed air to produce a loud and powerful sound signal. It is typically made of brass or other durable materials and is designed to withstand the harsh marine environment. The air horn works by releasing compressed air through a reed or diaphragm that vibrates rapidly, producing a loud and distinctive sound. The pitch and tone of the sound can be adjusted by changing the pressure and flow of the compressed air. Marine air horns are commonly used on ships and boats to signal other vessels, to warn of potential hazards or danger, and to communicate with other crew members or personnel on board. They are also used by port authorities and other marine facilities to signal the arrival and departure of ships, as well as to warn of emergencies or other critical situations. In addition to their use on ships and boats, marine air horns are also commonly used in other industries, such as mining, construction, and industrial safety, where a loud and powerful signal is needed to alert workers to potential hazards or dangers.

Application:

The marine whistle is suitable for various vessels, such as ordinary oil tankers, bulk carriers, container ships to large oil tankers (VLCC), large container ships, large ore carriers (VLOC), ocean-going scientific research vessels, chemical and product oil tankers, as well as ultra-deep water semi-submersible drilling platforms, jack-up drilling platforms, and large offshore floating production storage vessels (FPSO) , deep-water engineering survey ships, etc.

Principle of marine air horn:

The marine whistle realizes man-machine dialogue through the "Fog Navigation Automatic Control System" with "Microcontrollers" as the core, the system automatically outputs "signals" according to the set "actual environment", drives the relay, and connects the main power supply to the motor, the drive motor works. The sound generation system takes the motor as the driving force, and drives the eccentric shaft to rotate at a high speed through the teeth. The eccentric shaft drives the piston to reciprocate at a high frequency in the piston cylinder, compresses the air in the compression chamber composed of the piston and the piston cylinder, and drives the sounding body (sounding diaphragm). Sound, through the resonance of the resonator, the sound is strengthened, so that the horn emits a corresponding "fog horn" signal.

Knowledge of marine air horn:

Microcontrollers: an integrated circuit chip, which uses the ultra-large-scale integrated circuit technology to integrate the central processing unit CPU, random access memory RAM, read-only memory ROM, various I/O ports and interrupt systems, timers with data processing capabilities. /Counter and other functions (may also include display drive circuit, pulse width modulation circuit, analog multiplexer, A/D converter and other circuits) are integrated into a small and complete microcomputer system on a silicon chip. It is widely used in the field of control.

Intermediate relay: used in relay protection and automatic control systems to increase the number and capacity of contacts. It is used to pass intermediate signals in the control circuit.

Main material	The main material is HSi80-3 silicon brass. It has high corrosion resistance, good wear resistance and is not easy to crack.	Some vendors use aluminum instead of brass. The proportion of aluminum is less than 1/3 of copper. The price of aluminum is only 1/3 of copper. Its cost is only 1/9 of copper.
piston	The piston is a fragile part. The piston made of high quality brass can be used for at least 20 years.	A piston made of aluminum can corrode in a year or two of salt spray.
Rubber “O” ring, gasket	Made of high quality rubber, with excellent heat resistance, cold resistance, aging resistance.	Use general rubber, rubber O-ring and gasket easy to aging wear.
