After the generator set is placed for a long time, the dust will be more and more, which is a common problem of many mechanical equipment, the increase of dust makes the diesel engine add a lot of trouble. During the use of the generator set, the dust will have a bad effect on the insulation performance of the generator set. Ricoda generator set manufacturers tell you the specific frequently asked questions as follows:
1. Dust on the insulation surface combines with oil steam and water for a long time to form a hard shell, which gradually cracks under the action of thermal stress, resulting in cracks in the insulation film layer of the motor, which is easy to cause turns and phases of the motor as well as ground insulation breakdown fault.
2.Because the dust mechanical and chemical action, erosion winding insulation, is the main factor to destroy the insulation layer.
3. The dust immersed in the insulation gap will play an "abrasive" role in the insulation of the conductor of electromagnetic vibration, causing short-circuit fault between turns.
4. Due to the influence of dust, the loss Angle tangent of the generator medium will increase, and the leakage current will increase; Shorten the climbing distance of the insulation meter.
5.The dust falling on the windings, the core and the surface of the housing will make the cooling condition of the generator worse and reduce the effect of ventilation and cooling.
6. When the dust is non-conductive and non-flammable material, it will not have much impact on the motor coil, but on the bearings at both ends of the motor shaft. After the bearing is damaged, it will cause the stator and rotor phase friction and heat, and burn out the coil.
7.The dust and sand in the air is relatively more, easy to cause the rapid loss of some parts of the unit, if not properly handled, will lead to a lot of dust in the machine, making the unit of some pipes appear blocked phenomenon.
