Energy consumption in the machinery industry has always been an important issue for manufacturers and users. Increasing the energy consumption utilization rate of excavators can not only improve machine efficiency, but also reduce fuel consumption and save expenses. So what are the energy consumption of the excavator hydraulic system?

1: Overflow. The overflow situation of the excavator mainly occurs when the work is overloaded. At this time, the output pressure of the hydraulic pump is greater than the pressure of the safety valve, causing the hydraulic system to overflow.

2: Along the way. This situation is mainly caused by the occurrence of viscous friction, which increases the friction force and causes the loss of bushing power. For this situation, it can be improved by selecting suitable materials or optimizing the pipeline to reduce the loss caused by pressure along the way.

3: Match. During the work of the excavator, due to the rapid load change, especially in the process of small load and high-speed operation, it is not easy to match. Only a quick response loop can be installed to solve this problem. For example, load sensitivity can be added to the excavator system. system.

4: Kinetic energy and potential energy. When the boom and stick of the hydraulic excavator work, due to the larger mass, the kinetic energy and potential energy generated are also larger, resulting in loss of kinetic energy and potential energy.
