System of the WD305 series diesel engine Starting system Jan 18, 2018

Starting system mainly has battery, starter motor, charging generator and some accessories wire, etc.

In the work, always pay attention to the battery voltage and the proportion of electrolyte, the proportion of electrolyte should be 1.28~1.29 (atmospheric temperature 15℃), usually is not less than 1.27. Under normal circumstances, diesel engine charging generator can guarantee to maintain the state of sufficient electric battery. But in special circumstances, such as diesel engine stopped for a long time, possible battery voltage shortage phenomenon, at this time should be in other power supply to the battery charge.

Always check starting motor fasteners coupling is strong or not, wire contact is close or not, and eliminate accumulated pollutant, coated with a little grease to prevent rust. Always check the wire insulation is damaged or not. Periodically remove dust band. Check the commutator surface is bright and clean. Within the framework of the carbon brush in whether there is stuck phenomenon. Carbon brush spring pressure is normal or not, and remove dust. If discover the carbon brush wear too much, commutator surface singeing serious and other fault, should remove the repair.

Charging generator by triangular rubber belt drive in use, shall regularly check the triangular rubber belt tension force, to ensure the normal charge. Silicon rectifier generator and battery must be used together, the line connection conducted as per requirement, and connection should be correct, reliable anode must not pick the wrong or pick back, or will damage the generator. Silicon rectifier generator and the plate with ball bearing, bearing lubrication with composite calcium base grease, grease in the use of about 1000 h ours need to change, when changing, filling quantity should be appropriate, back cover bearing inner oil unfavorable overmuch, too much easy to overflow splash in the slip ring caused bad contact, affect the performance of the charging generator. Silicon rectifier generator structure is simple, do not need special maintenance, usually just use bellows or compressed air to motor in the dust, keep air way clear, observe the carbon brush and slip ring contact situation, check the carbon brush wear and the fastener tighten situation.

Note: Generator operation, are not allowed to use screwdriver (driver), and other metal items will be positive and terminal and casing or negative sub to see if there is a spark to determine whether charging generator, so easy to damage the components.http://www.wandiengine.com/
