The reasons why small loaders cannot catch fire are as follows:
?? 1. analyze the reason why the loader can't catch fire and determine the failure of the diesel primary filter.
?? 2. remove the fuel injection pump inlet pipe connector and use the hand pump to pump bubbles.
?? 3. check whether the oil volume of the diesel tank is sufficient and whether the oil supply pipeline has no leakage. The connector is flat and loose.
?? 4. analyze the reason why the small loader cannot catch fire between the base of the diesel primary filter and the sedimentation cup. The loader cannot start the fire. Add a sealing gasket of appropriate size before testing the machine.
What is the reason why the small loader cannot be started?
?? 5. According to practice, it is analyzed that the reason why the loader diesel engine cannot catch fire is probably the oil circuit.
?? 6. analyze the diesel engine of the loader. Put the connector into the oil basin and pump oil by hand. The oil output is normal and the bubbles disappear.
?? 7. the small loader cannot catch fire. Disassemble the oil inlet pipe joint of the diesel primary filter, and there is no blockage or air leakage in the direction of the oil tank.
?? 8. check whether the connecting bolts and oil pipe joints between the diesel primary filter base and the sedimentation cup are loose, but it is found that the rubber sealing gasket between the base and the sedimentation cup is thin, and the diameter of the diesel primary filter base is obviously too small, resulting in the above failure because the air enters the low-pressure oil circuit due to poor sealing.
?? 9. check whether the compression force and valve clearance of the cylinder of the small loader work normally.
