Why did the small mixer suddenly shut down? If there is a problem, there will be a reason. Only by finding the corresponding reason, can we better solve it and prevent it.
After confirming that the oil circuit is unblocked and there is no air in the diesel engine supply system, the cover plate of the oil pump can be removed, the operating handle can be moved, and the pull rod of the oil pump can be pulled to see whether the pull rod is flexible and whether the plunger spring is broken.
Under the condition that the pull rod of the small mixer is flexible and the plunger spring is not broken, the diesel engine can be started to run at a moderate speed for 10 minutes. If the fire is still broken, a copper hammer can be used to gently tap the large nut of the fuel transfer pump to listen to the sound of the diesel engine. If the sound is abnormal, it means that the piston and push rod of the fuel transfer pump are jammed for repair or replacement.
Remove the fuel injector assembly and rotate the crankshaft for several cycles, which means that water is ejected, indicating that the cylinder head and cylinder block have cracks or sand holes. In this case, you can explain to the user or report to the small mixer company.
After the low pressure oil flow is unblocked, the air in the oil circuit can be removed by the hand pump, and the air release screw of the pump head can be opened until there is no bubble, then the air release screw can be tightened.
The nozzle does not atomize, the plunger spring and spring seat of the oil pump are broken, stuck and do not work, or there is water in the diesel. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the user can use clean diesel oil to load it into a pot and use the oil circuit side connection method to test.
Open the oil tank switch of the small agitator, remove the oil inlet pipe of the oil transfer pump, and check the oil flow. If the oil flow is fast, it indicates that it is normal. If the oil flow is intermittent, check the oil circuit.
That's all for the correct solution to the sudden flameout of the small mixer. If you have any questions, please come to us https://www.zishangliaojiaobanji.cn Here to understand!
