1. Check oil flow
After the small concrete mixer stops, turn on the oil tank switch first, remove the oil inlet pipe of the oil pump, check the oil flow condition, if the oil flow is intermittent, clarify that there is a problem in the oil circuit. In the future, use the hand pump to exhaust the air between them, and screw off the air release screw of the pump head, and then tighten it after the bubble disappears.
2. Look at the piston and push rod of the fuel transfer pump
After admitting that the oil flow is normal, remove the cover plate of the oil pump and check whether the push rod is sensitive and whether the plunger has cracks. If everything is normal, test the engine and work at medium speed for 10 minutes. When the engine still shows flameout, knock on the big nut of the fuel pump and listen to the noise of the diesel engine. If the sound is abnormal, it is clarified that the piston and push rod of the oil pump are stuck and should be repaired and replaced in time.
The "first aid" method when the mixing truck stalls introduced by the manufacturer of automatic feeding mixer
3. Check the atomization condition of oil nozzle
If the nozzle does not atomize, it may also cause the mixer to stall. The nozzle assembly can be removed to check the opening pressure and atomization. If there is no problem with the nozzle assembly, the test can be carried out by the oil way side connection method. If the small concrete mixer still stops, it should be the engine problem. Remove the fuel injector assembly, roll the crankshaft, water gushes out, clarify that there are cracks in the cylinder head and cylinder block, and claim to report to the diesel engine manufacturer.
We are using the automatic feeding mixer in the driving also has such a common problem, in some working environment, the engine water temperature must be too high. As long as this happens, it will have a special impact on the equipment.
The automatic charging mixer will overheat the engine on normal roads. Slow down as soon as possible, drive the car in the shade of a tree, or park the car in a relatively cool place, but do not put out the fire quickly.
Open the hood, rotate the engine at idle speed and wait until the engine temperature gradually returns to normal. When the engine water temperature returns to normal, the engine will stop. Please wait a moment to cool down the engine water temperature, and then check the engine cooling water quantity.
At this time, the cooling water of the automatic water mixer may be obviously insufficient. After replenishing the specified amount of cooling water, check whether there are other abnormal conditions in the cooling system, start the engine, and then continue to run. In addition, check that the water tank louver is not blocked by foreign matters, whether the fan blade is running, whether the engine belt is not slipping and whether the engine water pump is running. These are some common faults in the operation of automatic feeding mixer, simple emergency plan.
