Repair and replacement: the purchase of a new carbon brushes for acceptance. Resistivity measuring carbon brushes, carbon brush wire measuring contact resistance, resistance to meet the manufacturer and the national standards. Strictly control the process to replace the carbon brushes, carbon brush in the same units must be consistent, do not use mixed interpolation. Before replacing the carbon brushes, polishing brushes carefully smooth things to make the brush in the brush holder should be a gap 0.2 0.4 mm, up and down freely within the brush holders. The lower edge of the brush holder and commutator working distance between the surface of 2-3 mm, the distance is too small, it will impact the commutator surface, easy to damage from excessive beating the brush is easy to produce sparks. Brush towards the contact surface is greater than 80% carbon brush section. Handling change, but should not be too many times to replace the carbon brushes, replace the carbon brush once quantity not exceed 10% of the total number of single-pole, below the top of the brush holder Brush top 3mm carbon brushes should be replaced as soon as possible, each time when replacing the carbon brushes you must use the same type of brush, but be careful to save and make full use of brushes. Brush replacement must be measured with calipers table brushless DC shunt, test temperature infrared thermometer, prevent individual carbon brushes due to overcurrent and overheating. For the slip ring or commutator commutator projections and depressions and other significant equipment problems, to take advantage of the opportunity to overhaul the unit fastening, turning and grinding. Strengthen inspection and quality control operation, to avoid due to poor maintenance quality or improper operation adjustment unit operation, the turbine oil leak, flung collecting ring, brush and increase the contact resistance between the collector ring. Brush holder and the brush holder unit in large and small repair to be careful when adjustment, playback and installation brush holder, angles and geometry to ensure that the original state, into the side and out of the edges must be parallel to the carbon brushes and commutator.Volvo TAD530GE diesel generator price Volvo TAD531GE diesel generator price Volvo TAD532GE diesel generator price Volvo TAD731GE diesel generator price Volvo TAD733GE diesel generator price Volvo TAD734GE diesel generator price Volvo TAD1341GE diesel generator price Volvo TAD1342GE diesel generator price Volvo TAD1343GE diesel generator price Volvo TAD1344GE diesel generator price Volvo TAD1345GE diesel generator price Volvo TAD1640GE diesel generator price Volvo TAD1641GE diesel generator price Volvo TAD1642GE diesel generator price Volvo TAD1643GE diesel generator price Volvo TAD520GE diesel generator price Volvo TAD732GE diesel generator price
