Starlight generator

In December, Starlight company and Liujiang Huateng Real Estate Development Co., Ltd., a subsidiary of Hejing Taifu Group, successfully signed a 600KW and a 640KW Cummins diesel generator sets. These two units are used as emergency standby power for the first and second phase of the Yunxi Four Seasons Garden. This is the second cooperation between our company and Hejing Taifu Group. Prior to this, our company has signed two sets of 520KW and 640KW   Cummins diesel generators   used in different projects of the Real Estate. In this project cooperation, in addition to the supply of the diesel generator sets, Starlight is also responsible for the installation and supporting environmental protection inspection and acceptance of the project, including: installation of diesel generating set and supporting environmental protection installation project, completion of equipment design and environmental design, manufacturing, testing, transportation, installation and commissioning, oper

Bearing shell seat hole is an important part of generator set crankshaf. If it is damaged, generator set will not work normally. Today Starlight shares the methods to repair b earing shell seat hole. How to repair bearing shell seat hole of   crankshaft   of   generator set ? When repairing the damaged and worn bearing shell seat hole, it is often used to pad another copper sheet behind the upper and lower bearing tile to adjust the expansion. Then the method of adding boring and scraping volume to the bearing tile is adopted. This method has certain effect on the bearing shell seat hole of low speed engine with uniform wear. However, the effect is not good for diesel engine if seat hole is wear and out of round, and the wear amount is more than 0.10 mm. If directly brush plating the worn seat hole, it can not guarantee the uniform coating; if thermal spray repair welding is adopted, the cylinder block will be heated and easily deformed; because of the large hole spacing

If there is air in oil circuit of diesel generator set, what will happen? Air has great compressibility and elasticity. When there is a leak in the oil pipe from the oil tank to the oil delivery pump section of diesel engine, the air will infiltrate, which reduces the vacuum degree in this pipeline. So that the suction of fuel in the tank is weakened, or even cut-off occurs, which causes the engine failure to start. If there is fewer air in the oil circuit, the oil flow can still be maintained and sent to the injection pump by the oil transfer pump, but the engine will be difficult to start or it will shut down automatically soon after starting. If there is more air in the oil circuit, it will cause fuel cut-off or significant reduction of fuel injection volume of the cylinder, and the diesel engine can not be started. At this time, it is necessary to remove the air in the oil circuit. Once air enters oil circuit of   diesel generator set , the diesel engine will be diff

Today Starlight manufacturer shares how to reduce generator loss in operation, hope it is helpful to you. The losses of diesel generators in operation can be divided into the following categories: (1) The stator copper loss is all the losses caused by the stator current flowing through the stator windings. (2) Iron loss is the loss generated by the generator's magnetic flux in the core. It is mainly the hysteresis loss and eddy current loss caused by the main magnetic flux in the stator core, and also includes the additional loss. (3) Excitation loss is the loss caused by the rotor circuit, which is mainly the copper loss caused by the excitation current in the excitation circuit. (4) The electrical additional loss is more complicated, mainly including the loss caused by the end leakage magnetic flux in the iron components near it, the loss caused by various harmonic magnetic flux, the tooth harmonic and higher harmonic on the surface of rotor resulting in iron loss
