Diesel generator set is the main backup power supply produced by manufacturing enterprises, and the main fuel it uses is diesel. At present, with the continuous rise of oil price, oil is also rising. In order to reduce the use cost, it is important to reduce the oil consumption as far as possible in the process of using the generator set, and do a good job of saving oil. So as a generator set user. How to do a good job of diesel generator oil use?

First of all, we need to understand the causes of excessive oil consumption, in order to take corresponding measures.

1. Normal wear caused by long-term use of the engine or abnormal wear caused by improper maintenance will make the cylinder liner of the diesel engine form longitudinal tensile marks, the cylinder diameter and the clearance of the piston side exceed the specified value, and the support force of the piston ring decreases correspondingly, resulting in unclean scraping of oil. Or because the inner support torsion spring in the oil ring is disconnected at the opening position of the oil ring, resulting in unclean oil scraping and participating in combustion, resulting in severe oil consumption symptoms, which are manifested as difficulties in starting the diesel engine, obvious blue smoke coming out of the exhaust pipe, and serious oil injection of the breathing apparatus. Moreover, the piston should be upward side, in the assembly of the inverted direction 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 fuel consumption of about 0.5 kg per day.

Two, when it is found that the oil consumption is too much, it should first check whether there is oil leakage at the connection of the body and gear chamber cover, the big plate on one side of the wheel, the back cover and the cover cover. It is necessary to observe whether the sealing gasket at each connection part is complete, and replace the damaged sealing gasket. If the gasket is complete, check whether the connection screws in each part are loose. Loosen the bolt with a wrench to the specified torque. If the above parts are basically normal, and the oil leak is in the frame position, the oil shell should be checked. The main inspection part is at the front end of the oil shell side on the same side as the wheel. Due to the loosening of the screw base, the wheel is pulled by the triangle belt and the Angle iron of the frame protecting the oil shell produces long-term friction, and the oil shell is worn through to form a gap and the oil leak is generated.

Three, valve duct wear serious will also affect the oil consumption of diesel generator set.

How to make the machine more energy saving?

1. Keep the oil supply Angle: the oil supply Angle offset, will cause the oil supply time is too late, the oil consumption increases.

2. Ensure that the machine does not leak oil: the solution is to paint the gasket with valve paint and smooth it on the glass plate, and straighten the oil pipe joint. Add diesel recovery device, can use a plastic pipe to connect the oil return pipe on the nozzle with the hollow screw, so that the return oil into the tank.

3. Improve the temperature of the diesel engine cooling water: the water temperature can make the diesel more complete combustion, oil viscosity will be small, can reduce the movement resistance, can achieve the effect of fuel saving.

4. Increase the diesel belt pulley appropriately, improve the pump speed when the diesel engine runs at a lower speed, so that the flow and head increase, to achieve the purpose of energy saving.

5. Purify oil before use: more than half of the faults of diesel generator sets come from the oil supply system. The treatment method is to use the bought diesel for 2-4 days to precipitate, which can precipitate 98% of impurities. If you buy and use it now, you can put two layers of silk or toilet paper in the filter of the oil 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 diesel generator set will be greatly reduced, and it can also give full play to the working efficiency of the generator set and reduce the cost of users.
