50KW Yuchai Diesel Power Generating Set with CE ISO certificate

Introduction of difference between alternator and generator

Today Starlight Power generator manufacturer shares the difference among alternator and generator with you. Alternator vs Generator Alternators and generators are two devices which generate electricity. An alternator can be called a type of generator. Although both these devices serve the same function, they are quite different in every other aspect. An alternator is a charging system for cars that produces electricity. Generators are used in the production of large-scale electricity. Both alternators and generators convert mechanical energy into electrical energy. The main difference between them is in regard to what spins and what is fixed. In an alternator, electricity is produced when a magnetic field spins inside the stator (windings of wire). In a generator, on the other hand, the armature or windings of wire spin inside a fixed magnetic field to generate electricity. Alternators are considered more efficient than generators. Alternators conserve energy by using on...

375kva 500kva water-cooled generator set China

Recently, a engineering project company purchased 4 sets Yuchai diesel generating set(300KW 2 sets, 400KW 2 sets) with Starlight Power company. The 4 sets generator sets are used for the construction site in front of new railway station.   300KW and 400KW open type diesel generators are equipped with Yuchai diesel engine YC6T series. It is a product independently developed by combining the advanced technology of large engines at home and abroad. It adopts four valves, turbocharged and intercooling, electronically controlled high-pressure common rail, and electronic unit pump. After optimization and verification of Yuchai's advanced combustion development technology, it has the characteristics of energy-saving and environmental protection, high reliability, strong loading capacity and good maintainability.     As authorized OEM supplier of Yuchai diesel engine, we have cooperated with Yuchai for many years and have good partnership, we can get a competitive price of diesel...

The Reason of generator faults alarms

Diesel generator set is a power generation equipment, it uses diesel oil, driven by a diesel engine to generate electricity. The whole set of diesel generator is generally composed of diesel engine, generator, control cabinet, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components. The alarm function of the diesel generator set will automatically start and sound when the diesel generator has the following conditions: 1.Over speed. 2.High water temperature in water tank. 3.Low oil pressure. 4.Over current display on the control panel. 5.Over voltage. 6.When other abnormal phenomena occur, the alarm function of diesel generator set starts or the self-protection function of diesel generator plays a role.   What is the reason of faults for low voltage shutdown? 1.Mechanical speed regulation of diesel engine Diesel engine speed regulation includes electronic speed regulation and mechanical speed regula...

The reasons of Deutz diesel generator set overexcitation

When Deutz diesel generator or transformer has overexcitation fault, it does not always cause obvious damage to the equipment, which is easy to be neglected. However, repeated over excitation will cause insulation aging and reduce the service life of the equipment due to overheating. The control of generator stator voltage is realized by adjusting the magnitude of rotor excitation current. The excitation corresponding to the amount of electricity generated is normal excitation. When the stator operating voltage is higher than the rated voltage, it is called overexcitation. Conversely, the stator operating voltage below the rated voltage is called underexcitation. In practice, there is a definite positive and negative value above or below the rated voltage. Different generators have different   excitation control system   and different excitation values.   Generators and transformers are composed of iron core windings. If the applied voltage of windings is U, ...

The Difference: Water-cooled Generator VS Air-cooled Generator

The cooling way of diesel generator has water-cooled and air-cooled, what is the difference between water-cooled generator and air-cooled generator? Here is something you should know. Water-cooled Diesel Generator: Its cooling system uses water as the cooling medium, and then dissipates heat through cooling water tank and fan to ensure the normal working temperature of the diesel engine. The water cooling system consists of water pump, radiator, fan, thermostat, water jacket and water pipe. The coolant of the   water cooling system   is located in the water jacket of the engine. The temperature of the high temperature machine is absorbed and the temperature rises, the radiator is cooled by fans and upwind airflow, and then the coolant is pumped into the water jacket for cyclic cooling.  There are two ways of circulating coolant: the thermostat closes when the engine water temperature is below 70 °C, coolant flows through pump, water jacket, heater bypass pi...

What are the requirements of the Cummins diesel generator set as an emergency (standby) power station

Cummins Diesel Generator Set is mainly used as Emergency (Standby) Power Station . The power supply system of emergency power station is generally not allowed to operate in parallel with the municipal power grid. Therefore, electrical and mechanical interlocking devices should be installed between the main circuit breaker of emergency generator set and the circuit breaker of municipal power supply to prevent misparallel connection between emergency power station and municipal power grid.Emergency units only automatically supply power to emergency loads (i.e. first-class engineering loads) when power failure occurs in the city. When the city's power grid fails and the emergency diesel generator starts up and runs, the emergency load should not be greater than the rated output capacity of the diesel generator set.The emergency load of the first batch of automatic operators should not exceed 70% of the rated capacity of generators, which is the secondary load originally...
