Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to an integrated hydraulic control unit. Background technique [0002] In the hydraulic system design of traditional construction machinery, components are usually arranged according to the direction of the frame, resulting in scattered component layout, intricate pipelines in the vehicle, poor assembly and maintainability, and cumbersome component replacement and maintenance. At the same time, the decentralized layout leads to long pipelines, large pressure loss along the way, slow response speed, and high energy consumption. In the prior art, in order to cope with such engineering applications, the centralized arrangement is carried out to the maximum extent according to the specific structural form of the frame, but it is only a small-scale centralized arrangement, and the system design, assembly and debugging have not substantially reduced the complexity. degree.

[0002] In the hydraulic system design of traditional construction machinery, components are usually arranged according to the direction of the frame, resulting in scattered component layout, intricate pipelines in the vehicle, poor assembly and maintainability, and cumbersome component replacement and maintenance.

At the same time, the decentralized layout leads to long pipelines, large pressure loss along the way, slow response speed, and high energy consumption.

In the prior art, in order to cope with such engineering applications, the centralized arrangement is carried out to the greatest extent according to the specific structural form of the vehicle frame, but it is only a small-scale centralized arrangement, and the system design, assembly and debugging have not substantially reduced the complexity. degree
