Product Description

 Gerui Power Water Cooling 24V DC Electric Start 40kW Diesel Genset 50kVA Silent Power Generator Set

What is a diesel generator set?
A genset is a combination of a prime mover, typically an engine, and an alternator. An engine converts the chemical energy of a fuel to mechanical energy. That mechanical energy is used to spin the alternator rotor, converting mechanical energy to electrical energy. As the engine turns, it moves the belt, which turns the rotor shaft. The rotor is essentially a magnet, and the area around the magnet is a conductor, which is called a stator. These components work together to create electricity in the form of an alternating (A/C) current.

How does a diesel generator work?
A diesel generator works by converting diesel fuel into electricity through a process involving an engine and an alternator. Here is a simplified explanation of how it works:
1. Diesel Engine. The generator is powered by a diesel engine that burns diesel fuel in a controlled combustion process to generate mechanical energy.
2. Generator Alternator. The mechanical energy produced by the diesel engine is used to rotate the alternator within the generator. The alternator consists of a rotor (the rotating part) and a stator (the stationary part) wrapped in wire coils.
3. Electrical Generation. As the rotor spins within the stator, it creates a changing magnetic field. This induces an electric current in the wire coils of the stator according to Faraday's law of electromagnetic induction.
4. Voltage Regulation. The generated electricity is in the form of alternating current (AC). The generator has voltage regulation mechanisms to maintain a constant output voltage during varying loads and conditions.
5. Output. The AC electricity generated by the alternator is then routed through a circuit breaker and various control systems to provide power to electrical loads.

Production Processing

Our diesel generator set production workshop is a specialized facility where we manufacture a wide range of diesel generator sets. With advanced equipment and skilled workers, we ensure high quality production and efficient work procedure.

In this workshop, we produce diesel generator sets with various power outputs, from 7KW to 3000KW. Our products are mainly powered by well-known brands such as YUCHAI, WEICHAI, SHANGCHAI, MTU, SHANGYAN diesel engine company. These generator sets applications in industries such as telecommunications, construction, mining, and emergency power supply.

With years of experience in the industry, we have gained a reputation for reliable and high-quality diesel generator sets. Our production workshop is committed to providing customers with excellent products and services, and we strive to become a leading manufacturer in the global diesel generator set market.

The world's top brand engines and the most advanced fuel high pressure common rail technology (for some models) are used to got the best fuel consumption rate. The combustion temperature and air-fuel ratio in the cylinder are more accurately controlled, and the compression ratio is higher to ensure more efficient power output and lower emissions.

Generator excitation system with the most advanced solid-state automatic voltage regulator (AVR) or digital voltage regulator (DVR). The windings are made of high quality, high temperature and high voltage resistant enameled wire, insulating materials and insulating coating to ensure electrical reliability and insulation safety. The generator also has the characteristics of short transient voltage recovery time, with strong non-linear load capacity and electromagnetic compatibility.

The digital system uses a microprocessor as the core, with multiple languages available for selection, and it can be automatic control. Connected to the power supply through ATS, can be perform automatic switching between the mains power supply and the backup power supply, and also to parallel connection of multiple generator sets to meet the power supply needs of the generator sets.

Through the noise analysis software calculations and a variety of combinations of noise reduction solutions, reduce the fan rotation noise, eddy noise and engine exhaust noise effectively. The unit adopts a high performance impedance integrated silencer that can be reduce the noise by 15 to 35dB(A), greatly reducing the unit's operating noise and the impact on the surrounding environment, this makes our generator sets are more suitable for use in the night, residential, office and other noise-sensitive environments.

We use well-known brand radiator assemblies to provide the most suitable radiator for different brands and models of engines to perform the best heat dissipation effect, and equip the radiator with a protective cover to ensure the safe operation of the user.

Projects Gallery

Diesel generators are widely used in animal husbandry, shipping transportation, steamship, garbage disposal, water conservancy and hydropower, factory backup, outdoor welding, metallurgy mining, cold storage, municipal engineering, civil air defense projects, flood control and drought relief, highways, railway, hotels and guesthouses, real estate, data, communications industry, fire backup and other industries.

Certifications

To ensure the quality of our diesel generator sets, we requiring strictly and carefully testing at each stage of production. All products have passed ISO9001:2015, ISO14001:2015, ISO45001:2018 certification. We also have a professional research and development team that continuously improves our product design and develops new models to meet market demands.
