Summarize some methods to extend the life of diesel generator sets
When the diesel generator set is damaged, one of the failures is accidentally damaged. This may be because of unqualified selections or because of improper use of operating equipment and inadequate maintenance. Strictly follow the fuel precipitation filtration system. Diesel should be deposited at least 48 hours before use. The diesel used should conform to the standard mode of the season. Fueling tools should be clean and special. Refueling and storage should also be cleaned to avoid mixing into fuel to accelerate accidental wear and reduce the life of occasional debris.
Strict technical specifications include 100 hours of maintenance and fuel filter work and 500 hours of cleaning tank operation. If the filter loss effect is found to change in time, the fuel supply will not be dismantled once. I will disassemble for 500 hours under normal working conditions. Make sure that the site, hands, tools, and cleaning oil are clean during disassembly to avoid contamination.
When disassembling, do not beat randomly, do not pile up when cleaning, and should not be cleaned in the basin with other non-accidental parts, so as to avoid bumps and injuries. It is not necessary to randomly change the assembly position to meet the requirements of the machine. After the oil valve is installed, the oil nozzle is tightened and the required torque is tightened to ensure that the injector and injection pump are in good condition after assembly.
This is undoubtedly to improve the understanding of diesel generator sets and understand the structural characteristics and working principles of diesel generator sets. We must strengthen and improve the dual maintenance, operation, and achieve no adjustment when there is no failure, maintenance and inspection without knocking on the door, no touch, maintenance and cleaning, no messy assembly and adjustment, according to technical requirements. Everything, how to achieve the purpose to extend the service life.
- Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.
- The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
- Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0
- In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
