250kVA Soundproof Generator Set Silent Diesel Generator


Characteristics of Cummins silent diesel Engine:
(1) Cummins diesel generator set of basic design features:
Cummins diesel generator set cylinder design rugged, vibration small, noise is small; In-line six-cylinder four-stroke, smooth operation, high efficiency; Replace the wet cylinder sleeves, long life, easy maintenance; A two-cylinder cover, four valves per cylinder, intake full, mandatory water-cooled, thermal radiation is small, performance.
(2) Cummins diesel generator fuel system:
Cummins PT fuel system patented and unique overspeed protection devices; Low-pressure pipelines, pipe a small, failure rate is low, high reliability; High-pressure injection, burning fully. Equipped with a fuel oil supply and oil return one-way valve, the use of safe and reliable.
(3) Cummins diesel generator set Intake:
Cummins diesel generators are installed with dry-type air filter and air resistance indicators, the use of exhaust gas turbochargers, intake adequate performance is guaranteed.
(4) Cummins diesel generator set exhaust system:
Cummins diesel generator set using pulse dry-type exhaust pipes, which can effectively use exhaust gas energy, give full play to the engine performance; Unit has built for the 127mm diameter exhaust pipe and exhaust bellows, easy to connect.
(5) Cummins diesel generator cooling system:
Cummins diesel generator set engines used gear within the mandatory water-cooled centrifugal water pump, large flow channel design, good cooling effect, which can effectively reduce the thermal radiation and noise. A unique spin-mounted water filter, to prevent rust and corrosion, control the acidity and remove impurities.
(6) Cummins diesel generator set Lubrication system:
Variable flow oil pump, with the main oil-Road signal tube, the main oil path according to oil pressure to adjust the fuel pump to optimize access to the engine's oil production; Low oil pressure (241-345kPa), these measures can effectively reduce the pumping power loss to improve power, improve engine fuel economy.
(7) Cummins diesel generator set power output:
In the shock absorber can be installed before the dual-slot power output of the crankshaft pulley, Cummins diesel generator set is equipped with multi-slot front of the annex to drive pulley, can take a variety of front-end power output device.
