Diesel generators that may occur include the following: a diesel generator rotating part of the main rotor unbalance, couplers, couplings, drive wheel (brake wheel) imbalance caused. Better approach is to first find the sub balance. If you have a large drive wheel, brake wheels, couplers, couplings, and the rotor should be separately to find a good balance. Then there is the rotating part of the mechanical loosening caused. Such as: core brackets loose, oblique key, pin failure loose, not tight banding rotor will cause imbalance in the rotating part. Second, the mechanical part of the diesel generator set failure following main points: 1, diesel generator sets linkage section shaft misalignment, centerline do not coincide, centering incorrect. The main reason for this failure is generated during the installation of the poor, caused by improper installation. Another case is that some parts of the centerline of the linkage in the cold state is consistent coincidence, but after running for some time due to the rotor pivot silent generator rental, foundation, etc. deformation, the centerline has been destroyed, resulting in vibration. 2, diesel generator set and diesel generator set associative gears, couplings faulty. This failure is mainly for gear malocclusion, severe tooth wear generator rental prices, poor lubrication wheels, couplings skew, dislocation, gear coupling tooth, pitch right, the gap is too large or badly worn, will cause some vibration. 3, diesel generator sets itself defect structure and installation issues. This failure is mainly for journal oval, curved shaft between the shaft and the bearing clearance is too large or too small, bearing, base plate, a part of the foundation of the whole diesel generator set installed base stiffness enough, diesel generator sets and basic between the plates fixed is not strong, foot loose bolts, loose between the bearing and the base plate. The gap between the shaft and the bearing is too large or too small can not only cause vibration also allows the bearing lubrication and abnormal temperatures. 4, diesel generators drag load conduction vibration. For example: Turbine Vibration turbine made diesel generator sets, diesel generator sets drag fans, pumps imported vibration generator rental, causing vibration of diesel generator sets. Diesel generator sets in extreme environments how to use diesel generators as an emergency backup power, its main feature is easy to move, supply instant, then, we must consider the use of generators under various environmental factors. 1. High altitude (plateau) supporting the use of diesel engine generator set, especially naturally aspirated engine generator rental, when used in the plateau region, due to the thin air at sea level is not as much as the burning of fuel, and the loss of some power, for naturally aspirated engines, general 300m altitude increases the power loss of about 3%, while the work on the plateau and therefore, you should use a lower power to prevent smoking and excessive fuel consumption. 2. In extreme cold conditions and you should start by using the auxiliary equipment (fuel heater, oil heater, water jacket heater, etc.) the use of fuel oil heaters or electric heaters, the cold engine cooling water and fuel lubricating oil heating, so that the whole generator temperature, in order to successfully start. When the generator room temperature no lower than 4 ° C, install coolant heater (water jacket heater) to maintain the temperature of the engine cylinder at 32 ° C or more. For the following work will be reduced to -18 ° ambient temperature of diesel generator sets, also need lubricating oil heater (oil heaters), fuel pipes and fuel filter heater to combat fuel cure. Oil heater installed on the engine oil pan. Heating the oil within the oil pan, to facilitate the diesel engine start at low temperatures. Is recommended to -35 # -10 # light diesel oil. _ Trailer diesel generator generator rental (certified) _ Liwan generator rental is provided by diesel and Electrical Equipment Co., Dongguan ShangXi.
