Two 50kw Cummins Silent Diesel Generators Were Exported to Poland

 On September 3, 2024, Dingbo Power scheduled the production of 2 units of prime power 50kw diesel generators for a client from Poland. The two diesel generator sets have identical configurations. They are powered by DCEC Cummins engines, which deliver reliable power and low emissions, ideal for Stationary, Prime and Standby applications.

 

Technical data of 50kw gensets

 

Manufacturer: Guangxi Dingbo Generator Set Manufacturing Co.,Ltd.

Genset model: DB-50GF

Type: Silent type

Prime power:50kw/80kva

Standby power: 55kw/69kva

Rated voltage: 400/230V

Rated Current: 90A

Speed/frequency: 1500rpm/50Hz

Power factor: 0.8lag

Phase & Wire:3 Phase 4 Wire

Diesel engine: Cummins 4BTA3.9-G2

Alternator: Shanghai Stamford GR225E

Controller: SmartGen HGM7220N

 

These 50kw diesel generating sets are powered by Cummins 4BTA3.9-G2 engines, which have a prime power of 58kw/73kva and standby power of 64kw/80kva at 1500RPM. They are coupled with Shanghai Stamford three-phase brushless alternators, which are known for high efficiency and stable reliability. Regardless of operating conditions, these alternators generate electricity consistently and efficiently, reducing not only energy consumption but also downtime and maintenance time. The genset controller is SmartGen HGM7220N model, which can realize functions of single unit self-start, AMF, synchronization changeover, and cloud monitoring.

The generator sets are housed in sound-attenuated enclosures and their noise levels can be reduced to 75dB at 7 meters. Enclosing a generator set with a sound-attenuated structure can significantly reduce noise levels and comply with local ordinances and provide protection from the elements. Silent diesel generator sets are perfect for areas where noise control is crucial. If you’re planning on installing your generator in residential areas, it's a wise decision to invest in a power generator with a sound-attenuated enclosure.

 

What is the difference between open type and silent type generators?

 

Diesel generators can be categorized as Open Frame type, Silent/Soundproof type and containerized type based on structural design. Open frame diesel gensets and silent diesel gensets are two common types of power generators, and the core differences between them are noise control, structural design and application scenarios. When choosing a diesel generator, you need to choose the type that best fits your needs.

 

Open frame/type diesel generators

 

Open type diesel generators, as the name indicates, are exposed metal frame with no soundproofing. Typically, the noise levels of these generators are 85~110 dB(A). Their advantages include low cost, easy maintenance, and better cooling. Compared to silent diesel generators, they produce higher noise, which makes them unsuitable for urban areas. They are generally used in industrial plants, construction sites, field operations such as mining and oil fields and temporary emergency power supply in non-residential areas.

 

Silent/soundproof diesel generators

 

Silent diesel generators are enclosed in noise-reducing enclosures (sound-absorbing materials, baffles), with noise levels from 60 to 75 dB(A). Compared to open type diesel generators, they have a higher cost and reduced cooling efficiency. This type of generators comply with urban noise regulations and they are ideal for data centers, hospitals, schools, hotels and other sensitive areas.

 

Dingbo Power provides different types of generator sets, which can meet your specific requirements. Feel free to contact us with any questions, concerns, or inquiries to learn more about the products & services we provide.

How to Read Alarm Codes From SmartGen Genset Controller

Auto Module Control Panel is the configuration for nobody on duty controlling generators. This kind of panel adopts auto module control system, with large LCD display to show the menu, such as SmartGen controller. Features:   1. SmartGen 6110 can receive remote output signal from ATS and realize auto start and stop of generators. 2. SmartGen 6310 can realize all functions of 6110, add RS232 interface which can communicate with PC to realize remote operation.  3. SmartGen 6410 Auto Mains Failure controller, can realize all functions of 6310, furthermore can detect  ATS and control directly. The alarm of diesel generator controller is not the amount of stop alarm, which does not affect the normal operation of diesel generator. When the alarm occurs, the unit will not stop, and when the alarm conditions do not exist, the amount of warning will automatically disappear.  Today Starlight manufacturer mainly shares alarm codes for diesel generato...

How to know and solve faults of genset voltage transformer

 Today Starlight Power shares the common faults for voltage transformer of diesel generator set. Hope it is helpful to you. 1) The insulation between iron chips is damaged. Fault phenomenon: temperature rises during operation. The possible causes of the failure are: poor insulation between iron chips, bad use of environmental conditions or long-term operation under high temperature, which promote the insulation aging between iron chips. (2) Poor contact between grounding plate and iron core. Fault phenomenon: there is discharge sound between iron core and oil tank during operation. Cause of failure: the grounding plate is not inserted tightly, and the mounting screw is not tightened. (3) The iron core is loose. Fault phenomenon: abnormal vibration or noise during operation. The cause of failure: the iron core clamp is not clamped, and the iron chip is loose. (4) Turn to turn short circuit of winding. Fault phenomenon: during operation, the temperature rises, there is ...
