1. Fix the fueling rack of the high-pressure diesel pump of the plate bending machine at the maximum fueling level.
2. Reverse the crankshaft for several tens of degrees (to eliminate the empty back gap), then turn the crankshaft, and see the oil surface of the outlet pipe of the high-pressure oil pump move slightly, which is the time to start the oil supply. In order to measure accurately, a piece of soft rubber tube and a piece of Boron tube with an inner diameter of no more than 2 mm can be put on the oil outlet of the high-pressure pump, and the oil level should be raised to the middle of the Boron tube in advance. Can accurately see the oil level fretting.
3. Start the engine for inspection. If the adjustment is wrong, the fuel supply angle is too large in advance and the fuel injection is too early, which will also cause harm to the engine. The phenomenon is that white smoke is exhausted after starting, and the engine vibrates intensely when working at low speed. Second, the consequence is that the engine is working rough. CIF I The crankshaft connecting rod is subjected to excessive force. The wear is increased, the engine life is shortened, and the piston is even burnt due to the excessively high judgment. At the same time, the power drops and the fuel consumption increases. If you find the phenomenon of freshness, you should immediately check the oil supply angle in advance. , Adjust to the correct angle.
4. Check the crankshaft angle, find the error caused by wear, and make adjustments. After adjustment, turn the crankshaft of the plate bending machine according to the above method to verify that it is correct.
