Friends who operate concrete mixer trucks know that the machine makes a lot of noise during operation, but they don’t know how to deal with it correctly. Here are some causes of noise and prevention methods:
1. Blockage of the filter element of the concrete mixer truck will also cause high noise. The solution is to clean or replace the filter element.
2. The oil in the concrete mixer truck does not meet the requirements or the oil viscosity is too high, which will also cause noise. It is necessary to replace the hydraulic oil with low viscosity.
3. The oil level in the tank is too low, and the air on the oil surface is sucked into the pump. Add hydraulic oil of the same grade.
4. The oil suction pipeline is inhaled or blocked; check and tighten it to prevent air from being sucked in.
5. The rigidity of the pump mounting bracket is insufficient, which will cause vibration and noise during operation. Strengthen the bracket.
6. There is concrete storage in the concrete mixer tank that is bonded, which will cause noise during driving. It should be cleaned and shoveled.
