Concrete mixer truck cleaning and flameout problems

A concrete mixer truck is a special truck used to transport concrete for construction. Because of its shape, it's also frequently called a crawler wain. These exchanges are equipped with spherical mixing cans to carry the mixed concrete. During transportation, the mixing barrel will always be kept rotating to insure that the carried concrete won't solidify. After the concrete is transported, the inside of the mixing barrel is generally washed with water to help the hardened concrete from taking up space, so that the volume of the mixing barrel becomes lower and lower. Next, let's take a look at the cleaning and down issues of the 6x4 concrete mixer truck.

How to clean the exterior of the concrete mixer truck engine?

Step 1: Cover the concrete mixer truck electrical appliance with a plastic film, and also cover the upper side of the film with a semi-wet kerchief to help high-pressure water from rushing into the distributor, making it delicate to start the CNG concrete mixer truck.

Step 2: Use a high-pressure water gun to wash down the attached dirt on the inside of the machine room and the surface of the concrete mixer truck machine from the side of the concrete mixer truck machine in order from top to bottom.

Step 3: Directly spot the concrete mixer truck machine surface drawing agent unevenly on the bathed concrete mixer truck machine and the fringe of the machine room. After three twinkles, use a fiber-bristle encounter to clean all accessible corridors in the machine cube.

Step 4: Use a high-pressure water gun to quickly rinse off the dirt washed off by the brush.

Step 5: Then spray the concrete mixer truck engine exterior cleaning agent on the engine surface, and the operation steps are the same as above. Repeat again and again until the concrete mixer truck engine exterior is cleaned.

Step 6: Then dry the rinsed 8x4 concrete mixer truck engine with a semi-wet towel, and use a vacuum suction and air dryer to dry the places that are not easy to reach, and then air dry.

Step 7: Polish the plastic rubber parts inside the engine room with a plastic rubber protective agent, and then coat the metal parts.

Step 8: Eventually, use a clean-woven polishing kerchief to check the concrete mixer truck machine and the inside of the machine room aftercare.

How to deal with concrete mixer truck flameout problem?

1. Turn on the concrete mixer truck oil painting tank switch, remove the oil painting bay pipe from the oil painting delivery pump, and check the oil painting flow. However, it's normal, If the oil painting inflow is fast. However, check the oil painting circuit, if the oil painting inflow is intermittent.

2. After the low-pressure oil flow is smooth, use the hand pump to remove the air in the oil circuit, open the pump head air release screw, and tighten the air release screw until there are no air bubbles.

3. After confirming that the oil circuit is unblocked and there is no air in the diesel engine supply system, the oil pump cover can be disassembled, the operating handle can be moved, and the oil pump pull rod can be moved to see if the pull rod is flexible and whether the plunger spring is broken. Under the condition that the pull rod is flexible and the plunger spring is not broken, the diesel engine can be started and run at a medium speed for 10 minutes. When there is still a fire failure, you can gently tap the big nut of the fuel pump with a copper hammer, and listen to the sound of the diesel engine while tapping. If the sound is abnormal, it means that the piston and push rod of the oil delivery pump is stuck and need to be repaired or replaced.

4. If not, it should be considered that the fuel nozzle is not atomized, the plunger spring and spring seat of the oil pump are broken, stuck, and not working, or there is water in the diesel oil. Remove the oil nozzle assembly to check the opening pressure and atomization. If the oil nozzle assembly is normal, the user can put clean diesel oil into the pot and use the oil bypass method for testing. If there is still misfiring, it should be considered an engine problem.

5. Remove the fuel injector assembly, turn the crankshaft several times, and then water will be sprayed out, indicating that there are cracks or blisters in the cylinder head and cylinder block. When encountering this situation, explain it to the user or reflect it to the diesel engine company.
