The structure of the VTJZ series dry fire star muffler produced by our company is a resistant muffler. The structure of the muffler can ensure good sound damping performance in the middle and high frequency bands. The insertion loss of the muffler is about 25dB (A).

In the entire exhaust system, the muffler is a comprehensive index. In the design of the system, some of the following factors will affect the silence volume of the system. It includes wrapping sound insulation materials on the muffler and exhaust pipe; including the length of the tail pipe before and after the exhaust muffler; also including reducing the high-temperature airflow velocity. And the installed water jacket and so on.

The sound-absorbing material itself is not sound-proof, but a layer of galvanized iron is wrapped around the sound-absorbing and heat-insulating porous material to achieve sound insulation.

After the exhaust pipe extends from the top of the chimney, it should be bent to the edge of the top of the chimney, so that the hot air flow is ejected to the rear of the ship without any block. The change in acoustic impedance green is used to reflect the noise upwards and reduce the impact on the ship.

For systems with an exhaust pipe diameter greater than DN200mm, the noise radiation of the pipeline has the characteristics of a line sound source. More attention should be paid to the sound insulation of sound insulation bandaging and pipeline support points. .

As long as the above points are achieved, the noise reduction of the entire system can achieve the best effect.

The working pressure of the muffler is about 0.1~0.15MPa, and the test pressure in the workshop is 0.2MPa, for air pressure test.

THE FUNCTION OF THE MARINE SPARK EXTINGUISHING SILENCER:

THE MARINE SPARK EXTINGUISHER IS AN AUXILIARY EQUIPMENT OF THE MARINE EXHAUST SYSTEM PIPELINE, WHICH IS MAINLY USED IN THE EXHAUST PIPELINE OF THE MARINE GENERATOR, THE MAIN ENGINE AND THE MARINE BOILER.

MARINE SPARK EXTINGUISHING SILENCER IS AN AUXILIARY EQUIPMENT FOR THE EXHAUST PIPELINE OF GENERATORS, MAIN ENGINES, OIL-FIRED BOILERS, FIRE-FIGHTING DIESEL ENGINES AND OTHER EQUIPMENT IN SHIPS. ITS FUNCTION IS TO ELIMINATE THE NOISE OF THE EXHAUST WHEN THE EQUIPMENT IS WORKING, AND AT THE SAME TIME, IT CAN EXTINGUISH THE REMAINING IN THE EXHAUST PIPELINE SPARKS IN

THE DESIGN AND MANUFACTURE OF THIS PRODUCT IS BASED ON THE SHIPBUILDING INDUSTRY STANDARDS, COMBINED WITH THE REQUIREMENTS OF MODERN SHIPS FOR AN IMPROVED DESIGN. THUS FORMED OUR COMPANY'S DX SERIES OF ENTERPRISE PRODUCTS.

MARINE MUFFLER-MARS EXTINGUISHING MUFFLER FEATURES:

The spark extinguisher is silenced through the small hole on the muffler tube. When the airflow passes through the small holes, the frequency spectrum of the jet noise will shift to high frequency or ultra high frequency, so that the audible sound components in the frequency spectrum are significantly reduced, thereby reducing interference and harm to people.

THE TECHNICAL AGREEMENT OF VTJZ SERIES MARINE DRY SPARK EXTINGUISHING MUFFLER IS USUALLY MARKED AS

VTJZ-125A EMERGENCY GENERATOR SPARK EXTINGUISHING SILENCER / DRY SPARK EXTINGUISHING SILENCER
