Does A Self-Loading Mixer Experience Speed Reduction After Long-Term Use?

Does A Self-Loading Mixer Experience Speed Reduction After Long-Term Use? Yes, it is. In general, after a long time use of self loading mixer truck, it maybe have the issue of speed reduction. Why is it experience the speed reduction? Check the main reasons.

Reasons of Self Loading Concrete Mixer Speed Reduction

Fuel Supply Issue

After prolonged use, the fuel filter may accumulate impurities, leading to insufficient fuel flow, which affects the engine’s combustion efficiency and power output.

Ignition System Problem

After prolonged operation, the spark plug may wear out or accumulate carbon deposits, and the ignition coil may also fail, resulting in incomplete ignition and affecting combustion efficiency and power output.

Engine mechanical Problem

Over an extended period of use, the piston rings, valves, and cylinder walls of the engine may wear out, leading to a decrease in compression ratio, which in turn affects power output.

Fuel Injection system Issue

After prolonged use, the fuel injectors may accumulate carbon deposits or become clogged, and the fuel pressure regulator may also fail, resulting in inaccurate fuel injection and affecting combustion efficiency and power output.

Air Supply Problem

Following prolonged utilization, the air filter may become clogged, and the intake manifold may accumulate impurities, resulting in insufficient airflow, which affects combustion efficiency and power output.

These problems may occur due to common conditions such as wear, carbon deposits, clogging, etc. caused by long-term use, or they may be related to improper maintenance. Regular maintenance and timely troubleshooting and inspections are important measures to ensure the normal operation of the self-loading mixer truck and avoid speed reduction problems.

Inspection Items of Self Loading Mixer to Avoid The Speed Reduction Problem

Fuel supply:

Check to see if the fuel filter is clogged and needs cleaning or replacement.
Check whether the fuel pump is working properly and ensure sufficient fuel supply.

Ignition system:

Check the spark plug to see if it is damaged or dirty and needs cleaning or replacement.
Check that the ignition coil and ignition wires are functioning properly.

Air supply:

Check if the air filter is clogged and needs to be cleaned or replaced.

Check the air intake pipe for blockage or leaks.

Engine mechanical:

Check whether the crankshaft sensor and camshaft sensor are functioning properly.
Check the engine’s compression, a compression test may be necessary.

Fuel injection system:

Check whether the fuel injector is clogged and needs to be cleaned or replaced.
Check the fuel pressure regulator and fuel pump for proper operation.

Exhaust system:

Check the exhaust pipe for blockage or leaks.
Check the catalytic converter for damage or blockage.

The above listed are only some common causes and inspection items. If the speed reduction problem of self loading concrete mixer still can’t be solved after checking these problems, please seek professional AIMIX technicians for inspection and repair in time.
