Detailed Description

Oleos is from a Spanish hydraulic equipment manufacturing company and has cooperated with AAK for 3 years, mainly focusing on non-standard hydraulic cartridge valves. At the beginning of this year, their customers complained about the high energy consumption of excavators. Their engineer judged that the performance of the original hydraulic manifold parameters had declined and asked the original manufacturer to optimize them. 2 weeks later, there was no result.


Oleos contacted me. According to his hydraulic schematic diagram and original hydraulic manifold design, AAK engineers had a basic idea after discussion, but it would take time. Oleos said that he would be willing to wait even 1 year as long as effective improvements can be made. AAK engineers finally improved the structure after more than 2 months of continuous design adjustment. AAK sent 5 hydraulic manifold samples.


Last week, Oleos placed an order for 100 pcs of hydraulic manifolds. It was reported that with AAK hydraulic manifold installed on the equipment, the energy consumption decreased by 20%. AAK optimized the hydraulic manifold, including pilot control valve group, 4 two-way plug-in wide control components, valve block and its internal and external connections to form a four-way hydraulic manifold control system, which has 3 features: 


1. AAK hydraulic manifold adopts horizontal structure, with 4 main channels and several pilot control channels, multiple internal mounting surfaces and 2 external mounting surfaces.


2. The top of the AAK hydraulic manifold block is equipped with a boss for installation, a boss type step surface consisting of the boss and 2 parallel finishing planes, a mounting surface of the boss's convex part, 2 groups of pilot control valve groups are installed, and a mounting surface of the plane with parallel boss planes is installed. First, 2 two-way cartridge valve control components are installed, and a flange type control cover plate is provided.


3. On the front of AAK hydraulic manifold block, two other two-way cartridge valve control components are installed. The finishing mounting surfaces on the left and right sides are provided with two control oil ports for the main passage and connecting holes for installing bolts. The bottom and back of the valve block are external mounting surfaces, which are used as the orifices and connecting mounting surfaces of the output ports of the main channel, and mounting surfaces for auxiliary installation and connection.


This optimized hydraulic manifold can ensure the maximum part of the control requirements, including the differential circuit and flow regeneration, and is conducive to the layout and direction selection of the input and output pipelines. The most important thing is to greatly reduce the hydraulic resistance and save the energy consumption of the system.


AAK hydraulic manifold has tricks to reduce energy consumption. You can also try a small order!
