Diesel generator set is the main standby power supply produced by manufacturing enterprises, it uses the main fuel is diesel, and at present with the continuous rise of oil prices, oil is also rising, in order to reduce the cost of use, it is important to use the generator set in the process as far as possible to reduce oil consumption, do a good job of saving oil. Then as a generator set user. How to do a good job of diesel generator oil use?
First of all, we need to understand the reasons for excessive oil consumption in order to take appropriate measures.
First, the normal wear caused by the long-term use of the engine, or the abnormal wear caused by improper maintenance, will cause the cylinder liner of the diesel engine to form longitudinal tensile marks, the cylinder diameter and the clearance of the piston side exceed the specified value, so that the support force of the piston ring is reduced accordingly, and the phenomenon of oil scraping is not clean. Or because the internal support torsion spring in the oil ring is disconnected in the opening position of the oil ring, resulting in unclean scraping and participating in combustion, resulting in severe oil consumption symptoms, which are manifested as the difficulty of starting the diesel engine, obvious blue smoke coming out of the exhaust pipe, and serious oil injection of the breathing apparatus. In addition, the piston should be upward side, in the assembly due to the direction of the inversion of the combustion chamber to form an inverted state, although it will not affect the starting of the diesel engine, but the loss of oil will be quite serious, the daily fuel consumption of about 0.5 kg.
Second, when it is found that the oil consumption is too much, it should first check whether there is oil leakage at the joints of the body and the gear chamber cover, the large plate on the side of the wheel, the back cover, the cover cover, etc. It should be noted that the sealing pad of each connection part is complete, and the damaged sealing pad should be replaced. If the gasket is complete, check whether the connecting screws in each part are loose. Tighten the loose bolt to the specified torque with a wrench. If the above parts are basically normal, and the oil leakage is in the position of the frame, the oil shell should be checked, the main inspection part is in the front end of the oil shell side on the same side of the wheel, mostly because the screw is loose, the wheel is pulled under the triangle belt and the rack Angle iron to protect the oil shell for a long time, and the oil shell is worn through to form a gap and produce oil leakage.
Third, the valve duct wear will also affect the diesel generator set oil use.
How to make the machine more fuel-efficient?
1. Maintain the oil supply Angle: The oil supply Angle is offset, which will cause the oil supply time to be too late and the oil consumption will be greatly increased.
2. Ensure that the machine does not leak oil: the solution is to paint the gasket on the glass plate and smooth it, and correct the tubing joint. The diesel oil recovery device is added, and the return pipe on the oil nozzle can be connected with the hollow screw with a plastic pipe to make the return oil flow into the oil tank.
3. Increase the temperature of the diesel cooling water: the increase of the water temperature can make the diesel more complete combustion, the oil viscosity will be small, can reduce the movement resistance, and can achieve the fuel saving effect.
4. Increase the diesel pulley properly, increase the speed of the pump when the diesel engine is running at a reduced speed, increase the flow and lift, and achieve the purpose of energy saving.
5. Oil purification before use: more than half of the faults of diesel generator sets come from the oil supply system. The treatment method is to put the bought diesel oil on deposit for 2-4 days and then use it, which can precipitate 98% of the impurities. If you buy and use it now, you can put two layers of silk or toilet paper in the refueling filter of the fuel tank.
6. Adjust the injection pressure of the injector.
It is believed that as long as the above six energy saving schemes are done well, the fuel consumption of the diesel generator set will be greatly reduced, and the working efficiency of the generator set can be fully played to reduce the cost of users.
