Starlight generator

Working principle of Cummins generator PTG two-pole governor / speed regulator 1. Idling condition At idle, the throttle is in the closed position and fuel flows only through the idle throttle to the injector. If the rotation speed is reduced for some reason and the centrifugal force of the flying block is reduced, the idle speed spring pushes the governor plunger to the left to increase the cross section of the orifice leading to the idle oil passage, and the oil supply amount increases. When the speed increases, the PTG governor plunger moves to the right, the flow cross section decreases, and the oil supply decreases, thereby keeping the idle speed stable. The idle adjustment screw is used to change the steady speed of the idle speed. 2. High speed condition When the speed of the diesel engine increases, the plunger and idle spring of the PTG governor are compressed, which is mainly acted by the high speed spring. The left notch of the plunger groove of the PTG governor h

In our actual operation process, when using diesel generator, the oil level of diesel generator transformer is often too high and too low due. Why? Today Jiangsu Starlight company answers for you. 1. The oil level   is too high. The oil level is higher than the oil level line due to the increase of oil temperature. Sometimes the oil level reaches the top line or the oil level cannot be seen. The reason is as follows: The operation of the transformer cooler is abnormal, which causes the temperature of the transformer oil to rise and the oil to expand, resulting in the oil level to rise. The  oil level  of the transformer is much higher when refueling. Once the ambient temperature rises, the oil level will be too high. If the oil level is too high, which caused by the abnormal operation of the cooler. Check whether the surface of cooler is blocked by ash and whether the upper and lower valves of oil pipe are opened. Check whether the pipeline is blocked and whether the fan and

Today Starlight mainly to share how to store temporarily unused diesel generator. If a   automatic diesel generator   is not used for a period of time, a reasonable and feasible storage plan shall be made according to the required time. The diesel generator set shall be stored according to the steps. It includes cleaning the unit completely, keeping the unit dry and ventilated, and replacing new lubricating oil of proper quality. Completely drain the water in the water tank and conduct rust prevention treatment for the unit. Storage of automatic diesel generator when not in use in a short period of time. 1.Empty diesel oil. 2.Turn the piston of the diesel engine to the top dead center of compression. 3.Store indoors and and cover it with a cloth. 4.Don't put it in a wet place. 5.Do not put together with inflammable, explosive and corrosive articles. 6.Turn the crankshaft regularly. Storage of automatic diesel generator when not in use for a long tim

Diesel generator set is a common emergency power supply in civil buildings, the proper selection of diesel generator set is an important problem in the electrical design of civil buildings. So when we choose self-contained diesel generator set, how to select a suitable capacity according to the load? 1.Setting principle. Class I high-rise buildings shall be supplied power according to class I load requirements. Class II high-rise buildings shall be supplied power according to class II load requirements.  Article 3.1 of code for electrical design of civil buildings (JGJ / t16-92): The primary load shall be supplied by two power sources, when one power supply fails, the other power supply should not be damaged at the same time; When the secondary load conditions permit, two-way power supply should also be used for power supply, especially the secondary load for fire protection, the power supply shall meet the requirements of two return circuits. For the particularly important lo

If we can inspect and maintain 500kw Volvo generator after it runs for a long time, we will reduce more unnecessary troubles. So, how we should inspect and maintain? Please follow us. 1.Primary technical maintenance: 50-80 hours.   (Added to the content of daily maintenance) A. Replace and clean air filter if necessary. The air filter is an unconspicuous but important part of the whole diesel generator set. Once the air filter is too dirty, it may cause serious mechanical accidents, especially in the environment and areas with poor air quality. In order to avoid shortening the service life of diesel generator, after shutdown, check the air filter in time and whether the air filter is blockage and damage. If so, clean and replace it in time. B. Check and replace the fuel filter and water filter; C. Check the tension of the drive belt; D. Add lubricating oil to all oil injection nozzles and lubricating parts; E. Replace cooling water. 2.Secondary technical maintena
