Analysis of structure

An ordinary diesel generator set is mainly composed of three parts: diesel engine, generator and control system. The diesel engine and generator have two connection modes, one is flexible connection, that is, the two parts are joined together by the connecting shaft, the other is rigid connection, and the rigid connecting plate of the generator and the diesel engine flywheel are connected by high-strength bolts. The diesel generator set on the market is more rigid connection, the diesel engine and the generator are connected and installed on the public chassis, and then equipped with a variety of protective sensors, such as water temperature sensors, through these sensors, intuitively display the running state of the diesel engine to the operator, and with these sensors, you can set an upper limit, When the limit value is reached or exceeded, the control system will alarm in advance. At this time, if the operator does not take measures, the control system will automatically stop the unit. The diesel generator set is to protect itself in this way. The sensor plays the role of receiving and feedback various information, the real display of these data and the implementation of the protection function is the control system of the diesel generator set, the control screen is generally installed on the generator, known as the backpack control screen, there are also some independent screen placed in the operating room, known as the split control screen, the control screen through the cable and the generator and sensor connection, Respectively display the electrical parameters and diesel engine operating parameters. In addition, the generator set has a chassis, a coupling, a radiator, a fuel tank, and some are equipped with a muffler and an outer cover.

Operation processing

The generator set should be checked regularly after running for a period of time. The long line unit should be checked every 6-8 hours, and the standby unit should be checked again after stopping. The inspection parts can be carried out in the following aspects: Lubricating oil residue, air filter blocking indicator, coolant level, radiator and external ventilation, engine drive belt group, fuel supply, etc. After the generator set runs for every 50 hours, the water in the oil-water separator should be discharged and the electrolytic level of the starting battery should be checked. After 200-300 hours of operation of the new unit, it is necessary to check the valve clearance and check the fuel injector: after 400 hours of operation of the generator set, it is necessary to check and adjust the transmission belt, replace it if necessary, check and clean the radiator chip and discharge the sludge in the fuel tank; Oil and oil filters need to be changed every 600 hours of operation or at least every 12 months; The frequency of the lubricating oil replacement cycle of the unit is different according to the quality of different lubricating oil and the sulfur content of the fuel and the consumption of lubricating oil of the generator set. Every 800 hours of operation, it is necessary to change the oil-water separator and fuel filter, check whether the turbocharger leaks, check whether the intake pipeline leaks, check and clean the fuel pipeline; Adjust valve clearance after 1200 hours of operation; After every 2000 hours of operation, replace the air filter and coolant, thoroughly clean the tank radiator chip and water channel; Check fuel injectors, thoroughly check clean turbochargers, and thoroughly check engine equipment after 2400 hours of operation.
