Starlight generator

 After a long time use of diesel generator set, there will be carbon deposit in cylinder head and psiton if not maintain regularlly.  Carbon deposit of generator set is a kind of hard material with strong adhesion and poor heat transfer performance. As the engine is used for a long time, the carbon deposits will accumulate in the combustion chamber, the top of the piston, the intake and exhaust ducts, etc. It not only hinders the heat dissipation of combustion chamber and piston, but also reduces the volume of combustion chamber and makes the engine work more rough. If the carbon deposit adheres to the intake and exhaust valves and their pipes, the exhaust will be blocked and the air intake will be insufficient; if the carbon deposit is formed at the head of the fuel injector, it is easy to block the injection hole and cause poor fuel atomization. Therefore, it must be removed during maintenance.   The more advanced methods are ultrasonic cleaning and nuclear spraying, bu

 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 soun

  Automatic voltage transformer regulator (AVR) is a sealed electronic device, which can control the magnetic field of the exciter and adjust the rectifier output power of the exciter armature, so as to control the magnetic field current of the main machine and stabilize the output voltage of the brushless generator. It has low frequency and no input signal protection device. In addition, parallel compensation function is provided to meet the customer's demand for expanded capacity. Therefore, it is very important to maintain the voltage regulator (AVR).   What Cause Generator AVR Damage? 1.AVR circuit is composed of rectifier main circuit, voltage detection circuit and comparison control circuit. Excluding the possibility of damage caused by the quality of the original electrical components, in the whole AVR circuit, the working frequency of the main circuit and the comparison control circuit changes most frequently; the rectifier bridge of the main circuit and the transistor in t

  Battery is one of the important components of 500kw diesel generator set. Before we choose battery, we should know first its function in diesel generator set. What is function of battery for diesel generator set? 1.The battery is mainly used to start the diesel engine. There are one or more starting motors on the side of the diesel engine. They use DC 24 V (some small diesel generator sets will use DC 12V) to drive the starting motor to start the diesel engine. 2.To monitor the power supply, which is the power frequency alternating current (AC). The frequency of AC power is 50Hz and 60Hz, which is commonly used in various countries in the world. The distribution of civil AC voltage varies from 100 V to 380 V, and the domestic genset room generally use three-phase 380V) and the conditions of diesel oil, engine oil and coolant should meet the starting requirements before starting the diesel engine. 3.It is used for excitation (some types of diesel engines need to be excited after start
