Product Introduction
weichai 700kw 8M33D890E200 Silent Generator Set is a high-performance power solution designed for critical applications requiring reliable, low-noise operation. It offers a standard power of 700kW, a standby power of 770kW, and voltages of 400V/230V (three-phase, four-wire), customizable to suit different grid requirements. Its rated current is 1260A, meeting the power demands of heavy industrial equipment.
Engine Specifications
Model: 8M33D890E200(V-type 8-cylinder diesel engine jointly developed by Weichai and Baudouin)
Displacement: 26.14L (8-cylinder V-twin, four-stroke, turbocharged and intercooled)
Rated speed: 1500 rpm, balancing fuel efficiency and long-term durability
Fuel consumption: ≤200g/kWh at 75% load, significantly reducing operating costs
Starting system: 24V DC electric starter, capable of starting in low temperatures down to -20°C (optional preheating device for extreme cold conditions)
Noise Reduction Design
Silent Enclosure:
The unit utilizes a three-layer shielded, impedance-mismatched soundproof enclosure with the following features:
Acoustic Sound Isolation: A combination of 50mm thick high-density glass wool and perforated steel effectively absorbs and blocks noise.
Vibration Isolation: Rubber shock-absorbing pads and anti-vibration devices reduce mechanical noise transmission.
Optimized Ventilation: Multi-chamber intake and exhaust ducts with Helmholtz resonators reduce airflow noise. The silent version achieves noise levels of ≤75dB (A) at 7 meters.
Exhaust System:
Industrial-grade two-stage muffler and insulated exhaust pipe further reduce noise by 15-20dB compared to standard designs.
