When the diesel generator set is in use, the problem of the dirty surface of the slip ring or carbon brush is often overlooked. The carbon brush of the normal running generator is sealed in a closed cabinet, and the air outlet is on the slip ring fan under the south pole. Blow away the heat of the graphite carbon powder and carbon brush in time to achieve the cooling effect.

When scratches occur on the surface of the slip ring. It will increase the friction between the carbon brush and the slip ring, aggravate the abnormal wear of the carbon brush and the slip ring, cause the slip ring to generate more heat, and cause the carbon brush to jump; while the compression spring is under alternating stress for a long time Running, causing the compression spring to fracture and collapse due to fatigue. The final result of this incident was the uneven surface of the slip ring, the cracking of the carbon brush, and the breaking of the compression spring.

If the generator seals oil leaks or slings the oil to adhere to the carbon brushes and slip rings, on the one hand it will affect the heat dissipation of the carbon brushes. On the other hand, when the carbon brush sparks, the surface of the slip ring is dirty and the insulation strength between the brush posts It's not easy to ring fire. In addition, the slip ring has a spiral groove on the car, which is to increase the heat dissipation area of the carbon brush, improve the contact with the carbon brush, so that the carbon brush can be cooled more fully, and the carbon powder can be more easily removed. Oil stains are also easily attached to the spiral groove, which will also seriously affect its heat dissipation.

Fujian Quark Motor's dust-proof and silent series is based on the standard cold-rolled sheet for manufacturing trucks. It has the characteristics of high temperature resistance, rain-proof corrosion and no deformation. It is equipped with dust-proof baking paint to ensure the power generation unit in the sandy grassland area outdoor environment It can also work normally; and the built-in sand filter design effectively reduces the maintenance cost of this series of generator sets. At the same time, this series of generator sets can also be customized for moisture, rain, shock and thunderstorm protection according to the actual use environment of the customer.
