Marine Air Compressor Introduction

Ship's compressed air system

The ship's compressed air system is one of the ship's pipeline systems, which mainly provides compressed air for generators, main engine start-up, debris blown off at the seadoor and other places on board where compressed air is needed.

major component

The ship compressed air system is composed of air compressor, pressure switch, air cylinder, pressure reducing valve group, conveying pipeline, terminal equipment and control valve.

Appendage function

1, the air compressor is used to produce and provide compressed air equipment.

2. Pressure switch, a solenoid valve that can open and close air compressor according to pressure.

3. Air bottles are used to store compressed air produced by air compressors and to supply compressed air to system pipes. The general air bottle can withstand the pressure of 5MPa.

4. The ship's compressed air pressure reducing valve group is a functional valve group unit which reduces the intake pressure from the compressed air system to the working pressure required by the mechanical equipment (and place).

5. The function of the conveying pipeline of the ship's compressed air system is to transfer compressed air to mechanical equipment (and premises) to serve the ship.

6. Terminal equipment is the machinery or equipment that needs compressed air to work, is the use of compressed air terminal, that is, the service object of compressed air system.

7, control valve used to cut or open compressed air pipeline.

Air compressor operation

The air compressor opens when the pressure of the air cylinder is insufficient under the control of the automatic pressure switch, and closes automatically when the pressure meets the requirements of the system to ensure that the air cylinder has enough compressed air.

System work

The compressed air in the air cylinder is first reduced through the pressure reducing valve group, and then the control valve is opened to supply compressed air to the equipment that needs to be operated.

Standby facility work

In general, the design of ships must have spare air compressor and auxiliary air cylinder, when the main air compressor needs to be repaired, manual or remote control to open the spare air compressor to ensure the work of the system. Compressed air in the auxiliary air cylinder is usually not used. When the main air cylinder pressure is insufficient and the ship is in blackout or the air compressor can not work properly, open the outlet valve of the auxiliary air cylinder to supply compressed air to the system to ensure the normal operation of the system

Marine Horn

Marine horn is a set of sound signal equipment, general use compressed air or high pressure steam as power, have button and hand cable two type;

Fog horn is a set of ship automatic sound system design in fog navigation, can automatically control the whistle from the specified navigation signal.

Marine fog horn is sailing in fog environment used as signal whistle.Fog horn is a kind of signal. Usually whistle a minute,stop a minute, or whistle 30 seconds, stop 30 seconds cycle.


Marine Horn can be divide into Piston horn and Air Horn

 

Marine Piston Horn

Ship piston horn, automated intelligent control, is a kind of advanced and practical new type of modern ship navigation in fog equipment, is the upgrading product of aerial fog whistle.

major component:
marine piston electric horn consist of horn Sound system and automatic control system two parts.
Sound system mainly consist of motor, driven gear, eccentric shaft, piston, piston cylinder, vocal diaphragm, resonator, speakers and other parts, by mechanical connection, by mechanical connection, the components as assembly with independent functions.

Working principle
Through the MCU, the system automatically according to the actual environment output signal, driving the motor running. The vocal system use motor as the prime mover, through the gear drive high-speed rotating eccentric shaft, the eccentric shaft drives piston in cylinder seat make high-frequency reciprocating movement, compressed the air in chamber consist by piston and piston cylinder, driving sound diaphragm phonation. The voice is strengthened by resonance effect of the horn resonator, a fog signal corresponding.

Marine Air Horn

Ship fog horn is compressed air as power, driving the sounding body make fog signal. Therefore, it is necessary to ship with air compressor, a high volume of storage tank for gas transmission pipeline.

This product is suitable for medium and large vessels;

Manual -- "ship navigation in fog horn CB881-84" power box, electric control box, electromagnetic valve using manual cable control horn sound.

Electric - "ship navigation in fog horn CB881-84"  power box, electromagnetic valve, use manual cable or  power box button to control horn sounds, with waterproof button 2pcs and accessories, spare parts

Electronic control -- "ship navigation in fog horn CB881-84" with electric control box, electromagnetic valve, can be manual control, electric control and navigation automatically send all conform to the national standard of audio signal, with full equipped, spare parts.

 

 WDK type navigation in fog horn automatic controller can control ship whistle at sailing automatically send periodic signals, can also be manual button to issue any rhythm control signal.
