1. When the engine speed of medium-sized concrete mixer decreases, first test the output power of the engine itself. If the output power of the concrete mixing plant is lower than the rated power, it may be poor fuel quality, low fuel pressure, defects in the brake and its control lever and carbon deposition in the turbocharger. If the engine output power is normal, you need to check whether the flow of the hydraulic pump does not match the output power of the engine. For such faults, start with the electrical system, then check the hydraulic system and the mechanical transmission system.
2. The Medium-sized concrete mixer slow working speed of the mixing drag pump is mainly due to the decrease of engine power and internal leakage of the hydraulic system caused by the wear of all parts of the whole machine. At this time, it is necessary to overhaul the whole machine and repair and replace the worn out parts. Medium-sized concrete mixer (automatic idle speed) technology of mixing trailer pump effectively controls fuel consumption and engine wear. There is also variable pump control system, which has higher precision and improved efficiency!
3. Daily maintenance of mixing trailer pump of medium-sized concrete mixer in order to prevent the failure of excavator, great attention should be paid to the maintenance of mixing trailer pump during daily use. Moreover, the Medium-sized concrete mixer and repair of the mixing drag pump shall be carried out in strict accordance with the operating instructions. Improper maintenance may lead to seal damage, slurry leakage or other parts damage.
The key point of mechanical engineering equipment such as Medium-sized concrete mixer is maintenance rather than troubleshooting. Don't wait for the failure to be solved. As long as the correct operation and normal maintenance are carried out according to the equipment manual, the probability of failure is still very low.
