The generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy and consists of a power system, a control system, a silencer system, a damping system, and an exhaust system. The turbine is driven by a hydraulic turbine, a steam turbine, a diesel engine, or other power machinery to drive water flow. The energy generated by air flow, fuel combustion, or nuclear fission is converted into mechanical energy for transmission to a generator, and then converted by a generator to electrical energy for output to electrical equipment. Generators are used in industrial and agricultural production, national defense, technology and daily life. With a wide range of uses, in recent years, with the advancement of technology, as a high-quality choice for home emergency power sources and field trip power supplies, lightweight portable small generator sets have begun to enter the daily lives of residents. Let us follow Xiaobian together to learn about power generation. Some common problems with the use of the unit.
1. Overload problem.
For example, if a 100 KW machine is required, a 100 kW standby power diesel generator unit is directly purchased. Overloading operation for a long time is quite unfavorable to the operation of the generator set.
2. The problem of poor heat dissipation.
Because the environmental factor is that the engine fan does not blow the heat of the water tank, so that the water temperature rises, causing the lubrication oil temperature to rise, resulting in insufficient oil pressure, poor lubrication, resulting in pull cylinder, piston, bearing and other moving parts damage, damage and affect The normal operation of the engine.
3. Maintenance issues.
Failure to perform maintenance on time leads to over-dirty oil, lower viscosity, and filter clogging, resulting in insufficient lubrication. Damage to moving parts may occur. Damage may result in major machine failures. Diesel fuel quality may also cause diesel filter clogging due to oil quality problems. Poor, the machine has insufficient load, such as the first time the machine is operating for 50 hours to do the first maintenance, after every 200 hours to replace the oil, oil filter, diesel filter, Ito generator regularly check the air filter dust , there is a problem immediately replaced.
4. Staff care issues.
No matter how good the machine, even the best equipment, if the responsible person does not look after, the machine life is not long, all in the machine's boot check, running regularly check, do a good job viewing records is also very important, this part is important importance.
Diesel generator oil generally passes through the gap between the piston ring and the ring groove, and the gap between the valve and the tube enters the combustion chamber. The direct reason for the break-in is that the first piston ring is attached near the top dead center due to a sharp drop in its moving speed. The oil above it is thrown into the combustion chamber. Therefore, the clearance between the piston ring and the piston, the amount of scraping oil and the oil scraping capacity of the piston ring, the pressure in the combustion chamber and the viscosity of the oil are closely related to the oil consumption.
Due to the bending of the connecting rod, the deviation of the piston due to the machine's shaping tolerance cannot be achieved (the marks are the two ends along the axis of the piston pin hole, and the marks of the wear of the cylinder sleeve and the piston appear on the piston ring and the other piston skirt). It is also an important cause of the increase in oil consumption.
The use of twisted rings and combination oil rings has a significant effect on reducing oil consumption. In particular, the combined oil ring is light in weight, and the three-piece structure has no pumping effect. It is compliant and adaptable to the cylinder wall. The side close to the ring groove.
From the operating conditions, the use of oil viscosity is too low, the engine speed and water temperature is too high, the cylinder liner deformation exceeds the limit, the number of frequent start and stop, engine parts wear too much, the oil level is too high, etc. will increase the consumption of oil.
Therefore, if it is found that the fuel consumption of diesel generators is increased compared to usual, the first step is to find out what caused the cause, and then to the right medicine, effectively saving fuel energy, reducing unnecessary costs.
