Hydraulic Manifolds Higher Efficiency

With hydraulic manifolds, the energy consumption of the original unsalable equipment not only decreased by 20%, but also became hot seller
is from a agricultural machinery equipment company, mainly responsible for purchasing hydraulic components. In the second half of last year, the sales of one of their rotary tillers were poor. Users reported that the equipment was insensitive and inefficient, and the fuel consumption was 10% higher than that of the same type of equipment. The boss realized that there were hidden dangers in the hydraulic manifolds and asked the engineers to check the causes. However, more than 1 month had passed and there was no practicable plan. The boss was worried and asked to contact the original hydraulic manifold manufacturer to see if they could provide technical support, but they were only good at producing hydraulic manifolds according to the drawings. Connor also asked all his manufacturers of hydraulic components, but none of them gave a plan. When reported these to his boss, he could only helplessly look at his boss shaking his head.

the display and introduction of hydraulic manifolds, and left a message: what is the relationship between hydraulic equipment with high energy consumption and slow response and hydraulic manifolds I understood that Connor had a problem with hydraulic manifolds, but it was difficult to answer. After several communications, I learned that his boss was worried, and wanted to solve the problem that had plagued his company for nearly 3 months.

According to the hydraulic manifold drawings and the video of rotary tiller work sent by engineers had discussion. The probability was that the hydraulic manifold design had hidden problems. From the analysis of hydraulic manifold and system schematic diagram, there were certain energy conflicts between the design of some oil circuits and the selection of hydraulic valves. could redesign the hydraulic manifold to match their equipment. also readily paid the development cost. 1 month later, sent the hydraulic manifold samples. 2 months later, said that after their rotary tiller was installed with hydraulic manifolds, it was responsive during operation. The operation was more than 20% higher than before, and the fuel consumption was also reduced by 20%. The customer feedback was good, and more and more customers came to try it out.

told me privately that he had seen his boss's long lost smile. The boss paid more and more attention to him. He will be promoted to the management next month.

hydraulic manifold has 3 advantages
1. engineers have experience in hydraulic manifold design, especially in oil circuit design. Ensure flow distribution as required, eliminate bypass throttling loss and reduce energy loss.

Only AAK was able to produce the hydraulic manifold blocks, and its technology is not inferior to American and Japanese counterparts

Scott comes from an equipment company in the United States. In the second half of last year, they developed a hydraulic equipment to be introduced at the exhibition. The chief engineer of the company requires the purchasing department to get all hydraulic manifold blocks arrive at the factory within 3 months. There is a hydraulic manifold block. Due to the slow production, the production time of 45 days is not enough. Scott disassembled the hydraulic manifold blocks, purchased the hydraulic valve blocks from one factory and the hydraulic cartridge valves from another factory. All hydraulic manifold blocks and those parts produced separately arrived at the factory in the United States in 3 months. The technicians in the workshop installed them. After a few days of commissioning, they found that there were oil leakage on one hydraulic manifold block, that is the one disassembled and produced in two different factories. The chief engineer requires getting a new hydraulic manifold block within 1 month, otherwise it will be too late to catch the exhibition.

Scott contacted the original manufacturer. As a result, the two hydraulic valve manufacturers prevaricated each other. Their engineers also tested the hydraulic cartridge valves and hydraulic valve blocks separately, and there was no abnormality. Scott tried to contact new manufacturers of hydraulic manifold blocks, but they all said that they couldn't get samples ready within 30 days. Scott was worried.

Scott saw on AAK website that a hydraulic manifold block was very close to the size he wanted to purchase, so he sent an inquiry. After two rounds of communication, we learned about the problems he encountered in purchasing hydraulic manifold blocks. I told him that if the hydraulic cartridge valves and the hydraulic valve blocks were approved to be no problem, the workshop technician might break the seal ring or shift the seal ring during the installation of the hydraulic manifold blocks. This kind of hydraulic manifold blocks purchased from different manufacturers and then assembled is easy to have problem. A customer of AAK encountered similar problems before. After Scott asked their mechanic to replace the sealing ring, there was no abnormality in the test run, and they could catch up with the exhibition. Scott is glad that the problem of hydraulic manifold block has been solved, and said that for all hydraulic equipment orders after the exhibition, the hydraulic manifold blocks will be purchased from AAK, and also asked us to send hydraulic manifold blocks with similar dimensions to the United States to test stability and service life.

For the Hydraulic Manifold Block with porous system like cranial nerve, after made samples successfully,
They have a special hydraulic manifold block, which includes 13 groups of M32 threaded holes, and all of them are stepped holes. At the same time, there are cross holes, straight holes, and bypass holes. The hole size is required to be more than 8. Compared with the hydraulic manifold blocks with 10 groups of normal threaded straight holes, it is not only complex in structure, but also 20% higher in precision. Arno knew that it was difficult, so he arranged 3 hydraulic manifold block manufacturers for proofing, which lasted 60 days, but all of them failed to meet the standard. This is a test order of hydraulic manifold block from an old customer. Arno wants to struggle again. Due to time constraints, he does not dare to use a new hydraulic manifold block manufacturer. His old hydraulic manifold block supplier is also unreliable. This makes , who has eight years of procurement experience, a little overwhelmed.

I had a hunch that this hydraulic manifold block was not simple. Because the PO of hydraulic manifold blocks given to me by is a challenge every time. engineers pondered over the drawing of hydraulic manifold block sent by , and it is really difficult to process, with very high precision. There are not only many pore systems, but also many deep holes, more than 20 groups of 4 deep holes, with a length diameter ratio greater than 25. For M32 threaded holes of stepped holes, the coaxiality between holes is required to be 0.02mm, and the coaxiality between threads and holes is required to be 0.045mm. This complex pore system structure is like the distribution of the nervous system of the human brain. Doctors without more than 10 years of experience in brain surgery may not be confident to operate on the operating table.

technical team, after 3 days of internal research and discussion, the plan has been worked out, and our chief engineer will handle the knife, starting from the production drawing of the hydraulic manifold block. However, I replied to that was only 90% sure that the sample of this hydraulic manifold block was successful, and the cost was not low. Maybe hesitated and didn't give any reply for 3 days. On the fifth day, received the development fee paid by him.

How does Chinese Hydraulic Manifold Manufacturer AAK ensure the reliability and longevity of the machining quality of hydraulic manifold blocks?

AAK customizes hydraulic manifold blocks for customers in multiple countries, including Germany, the United States, Russia, and Israeli military clients.

We strictly control the selection of materials, processing techniques, surface treatment, cleaning, and inspection to ensure the reliability and longevity of hydraulic manifold blocks like below:

1. Materials and Pretreatment
1) Material Selection
The valve block material should have a dense structure and be free of defects such as sand holes and interlayers. If necessary, non-destructive testing should be carried out.
If forging blanks are used, they need to undergo normalizing treatment to eliminate internal stress and non-destructive testing.
2) Pretreatment
Cast iron or large steel parts require aging treatment or pretreatment.

2. Machining process
1) Surface processing
The surface roughness of the hydraulic valve block must meet the design requirements, and the installation surface (such as the contact surface of hydraulic valves and pipe joints) must not have scratches to prevent leakage
Rough machining requires reserved precision grinding allowance, and the surface roughness Ra value after precision machining should meet the accuracy requirements.
2) Chamfering and deburring
Edge chamfer 2 45 (small valve body chamfer 45 ), keep the oil passage hole sharp and remove burrs.
All flow channels (especially intersections) need to be thoroughly cleaned of burrs to avoid residual effects on system stability.

3. Surface treatment and rust prevention
1) Coating and Marking
The surface can be plated with electroless nickel, with a thickness controlled between 0.008-0.012mm.
Steel seal markings should be placed next to each oil port, with a distance of �¢?�¥ 6mm from the hole opening, to avoid affecting the sealing performance.
2) Rust prevention measures
After processing, rust and dust prevention treatment should be carried out, and sealed and stored in a clean and dry environment.

4. Cleaning and assembly
1) Cleaning
Before assembly, the manifold block should be thoroughly cleaned using rust proof cleaning solution or kerosene/engine oil to ensure that blind holes and flow channels are free of iron filings and impurities.
Maintain pressure during flushing, and switch the solenoid valve to flush all channels.
2) Assembly
Check if the connectivity of the ducts is consistent with the schematic diagram, ensuring that the seals and components are all qualified products.
When using anaerobic adhesive to seal screws, it is necessary to clean the joint surface and let it stand for 24 hours before applying oil.

5. Inspection and Testing
1) Inspection
After processing, it is necessary to check the dimensional accuracy of oil ports, threads, counterholes, etc.
