Hydraulic transmission and control technology promotes the rapid development of hydraulic technology. This advancement also results in increasingly complex design and manufacture of hydraulic systems.
Hydraulic systems with integrated valve assemblies reduce piping and joints. They simplify system complexity and enhance circuit flexibility. These assemblies are compact, easy to install, and maintain. They minimize leakage and vibration, promoting system integration and standardization across various applications.
Integrated hydraulic systems center around the hydraulic header manifold, which features one or more specially pre-drilled multiple holes in the valve block body. Various hydraulic components, such as hydraulic valves, pipe fittings, and pressure gauges, are installed on it. The internal orifices connect to the component orifices to form a hydraulic integrated circuit, meeting system control requirements.
Design of hydraulic header manifold
In the design of hydraulic systems using hydraulic header manifold, valve block design is a critical and boring task. The hydraulic header manifold surface accommodates plate valve mounting and pipe fittings. Its internal orifices connect to valves, forming functional blocks. This setup supports complex hydraulic circuits within the local system.
The valve block body distributes hydraulic valves related to mounting holes for the hydraulic header manifold, along with oil holes, connecting screw holes, positioning pin holes, and common oil holes, connection holes, etc. This ensures correct connection of the holes without interference, sometimes establishing multiple holes in the process. Generally a slightly more complex valve block body has hundreds of holes, these holes constitute a crisscrossing hole system network. In the valve block installation layout, a variety of components should be as compact as possible, evenly distributed on all sides of the valve block body, not only to facilitate the installation, commissioning, but also in line with the aesthetic requirements, and the layout of the programme with the requirements of connectivity together with the aperture design of the starting conditions. Components connect through internal apertures, and for those that cannot connect directly, process apertures are necessary. At the same time, the design must also meet the non-connected apertures between the safety wall thickness and connected apertures at the intersection of the flow cross-section and other design quality requirements.
Example of a hydraulic block
Hydraulic header manifold itself can integrate various types of valves and related ancillary components, which plays a key integrated role in the hydraulic system, can simplify the installation circuit, so that the hydraulic system as a whole components of the installation and use more convenient. Simultaneously, designers can configure the internal piping structure of the hydraulic header manifold according to different requirements to meet various types of system control and operational needs.
