Volvo Cooling System Design

Summary of System Design The following points must be given extra thorough consideration when designing a cooling system: • The maximum ambient temperature the engine must operate in. • Cooling air flow direction, i.e. if a puller or pusher fan is to be used. A pusher fan is recommended for generator sets to avoid generator overheating. On mobile applications, consideration must be give to any slipstream. • Engine heat radiation causes a rise in cooling air temperature in pusher fan systems. • Generator heat contribution is 7-10 % of net engine power. • Additional coolers in front of the radiator (puller fan) or behind the radiator (pusher fan) will cause a rise in cooling air temperature and a reduction in airflow.  • The radiator may become clogged in dusty environments, which will impair cooling capacity. The radiator must be installed so that it can easily be cleaned. Grilles / filters are availabl...

Oil Transfer Pump of Diesel Generator

Oil pump is an important part of diesel generator. In the process of using the diesel genset, only regularly checking and maintaining the oil transfer pump can guarantee the normal operation of the generating set. Maintenance tips 1. Before installing the oil transfer pump on diesel generating set, check whether the model and specification are correct or not; remove rust preventive oil and choose the appropriate thickness gasket. In order to avoid piston running improperly, the gasket should avoid too thin or thick, and the tightening torque should be uniform to prevent damage to the oil pump. 2. The coarse filter core within the oil pump is easily blocked by cotton and other dirt, you should reguarly check and clean it. If the strainer is damaged, you should repair or change it timely. 3. There is a rubber seal between the hand oil pump piston and the hand oil pump body. Do not remove the rubber. If the rubber ring is damaged, you should replace it timely. 4. Ens...
