G12V190 Série 2000 ensembles de génération de diesel (300KW-800KW)

2000 series diesel generator set is powered by 2000 series diesel engine, matching with domestic and foreign high-quality generators produced by the diesel generator set, power range 300kw-800kw, and can be composed of two or more units to form a power station.

Structural characteristics of 2000 series diesel engines：

In order to adapt to the requirements of rig transformation and improve the reliability of diesel engines, the 2000 series diesel engines are matched with high efficiency (efficiency increased by 5%) and high pressure ratio (pressure ratio increased by 20%) and high flow rate (flow rate increased by 20%) SJ160 supercharger produced by Sino-Singapore Joint Venture Company, which replaces the original 20GJ supercharger and improves the performance and reliability.

(1) Adopt the round tube type high efficiency intercooler produced according to the technology of West Germany GEA company, instead of the original flat tube type intercooler.

glacière. Heat dissipation efficiency from the original 73% to 92%, to meet the requirements of increased charge air mass flow, so that the diesel engine performance and intercooler reliability is guaranteed

(2) The oil pump is changed from two parallel pumps in the original oil pan to a large oil pump installed in the front of the oil pan.

oil pump, and with automatic regulator. The flow rate of the pump is 14% higher than the total flow rate of the original two oil pumps, which is easy to ensure the oil pressure, easy to maintain, and also can automatically regulate the pressure.

(3) cylinder head with advanced heat-resistant alloy valve seat, to adapt to the valve and valve seat due to heat load and wear large requirements, to extend the life, improve reliability.

requirements, to extend the life and improve the reliability of the role.

(4) Adopt double pressure type oil pressure low automatic stopping device, creating conditions for remote start. (5) The use of the disengaged starting motor, not only saves the air source, easy to start, but also to ensure that the gear ring work reliably.

Fiable.

(6) Adopting new winged high-efficiency fan, the fan air volume is increased by 30% and the efficiency is increased by 15%.

(7) Adopt Japanese technology to manufacture a large heat sink with open window.

The heat dissipation area is increased by 50% and the heat dissipation efficiency is increased by 35% to meet the requirement of increased heat dissipation.
