Japan Kubota Diesel Generator Set

Japan Kubota Power Rare Earth Permanent Magnet Diesel Generator Set is a new product launched by Beidou. Beidou cooperates with many high-quality diesel engine manufacturers. Japan Kubota Diesel Generator Set is a purely imported diesel engine set, which has a great impact on the world and is subject to many Customers’ favorite.

Beidou launched the silent Kubota diesel generator, which solves the noise problem. The 8KW small generator, electric start single-phase generator, portable generator, diesel generator fuel economy, high thermal efficiency, and fuel consumption rate curve when operating conditions change The change is relatively flat, economical under low load, reliable and durable. The diesel generator set is solid, fuel-efficient and has a long service life. This is a silent diesel generator with a DC output of 12V, a single-phase electric starter generator, and a water-cooled four-stroke three-cylinder engine. Kubota’s products will always give people a refreshing feeling. Kubota’s diesel engine set is fuel-efficient, light-weight, low-noise, and low-displacement. The most notable feature is its small size. Among them, 10KW, 20KW, and 30KW generator sets are particularly small, and are especially suitable for customers who have high requirements for generator sets.

The noise of Kubota diesel generator set is a complex sound source composed of multiple sound sources. According to the noise radiation method, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the causes, the surface radiated noise of diesel generators can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source of diesel engine group noise.

1. Aerodynamic noise is due to the unstable process of the gas, that is, the noise of the diesel generator set caused by the disturbance of the gas and the interaction between the gas and the object. Aerodynamic noise radiated directly to the atmosphere, including intake noise, exhaust noise, and cooling fan noise.

2. Electromagnetic noise is the noise of the diesel engine generated by the generator rotor rotating at high speed in the electromagnetic field.

3. Combustion noise and mechanical noise are difficult to distinguish strictly. Generally, the diesel engine group noise radiated by the pressure fluctuation caused by the combustion in the cylinder of the diesel generator set through the cylinder head, piston, Lianxuan, crankshaft, and body is called combustion noise. The diesel engine block noise generated by the impact of the piston on the cylinder liner and the mechanical impact vibration of the moving parts is called mechanical noise. Generally, the combustion noise of direct injection diesel engines is higher than the mechanical noise, while the mechanical noise of non-direct injection diesel engines is higher than the combustion noise. However, the combustion noise is higher than the mechanical noise at low speed.
