Krischnan is from a hydraulic equipment manufacturing company in the United States. He has been engaged in hydraulic manifold procurement for only 1 year. In the second half of last year, they developed a hydraulic oil pump to promote for new. The hydraulic manifold used comes from the design of their engineers. They chose a hydraulic manifold manufacturer who has worked with them for 5 years to try samples. 2 months later, the commissioning was not smooth. After the equipment was started for a period of time, the pressure supply of the oil pump was unstable, resulting in high energy consumption of the equipment, which had no advantage over the peers. The boss asked that the problem be solved within 3 months. The engineer asked Krischnan to contact the original hydraulic manifold manufacturer to solve the problem, but the manufacturer only had production capacity and can not offer solution. Krischnan was worried that the technical department blamed the purchase for the abnormal test run and had to check with many hydraulic manifold manufacturers. 1 week later, only one hydraulic manifold manufacturer replied that the manifold might need to be redesigned, but he was not sure. Krischnan was worried about time being wasted day by day.
When browsing Google, Krischnan found an article of AAK about hydraulic manifolds and asked by email: Can you improve the hydraulic manifold design and make samples according to the working conditions of the equipment? I felt that he may have encountered problems on making samples for hydraulic manifolds. After communication, I learned that there was also a problem with the hydraulic manifold design. According to his hydraulic manifold drawings, as well as the condition of equipment commissioning, I told him that AAK was 80% sure to redesign the hydraulic manifold and sample it. If successful, it can help reduce the energy consumption of the equipment by 20%. Krischnan was happy but also worried when he learned that, but he seemed to have no choice but to bet on AAK's success. After 50 days, 5 redesigned hydraulic manifold samples were delivered.
4 weeks after the hydraulic manifold was sent out, Krischnan told us that the test run was smooth, the pressure supply of the oil pump was stable, and the energy consumption also decreased by more than 20%. The entire technical team was very happy and sure that it would be recognized by the market soon.
The improvement of this hydraulic manifold is the reverse thinking operation, from "why the pressure supply is unstable" to the oil circuit and oil hole. AAK did this way: composed of relief valve, hydraulic time-delay valve and check valve. The sparkle is that there are oil inlet, oil return and oil outlet holes in the valve body. Each oil hole is connected to two cartridge valves, and the control oil holes of the hydraulic time-delay valve and the relief valve are connected to the corresponding oil holes in the valve body. The setting of another cartridge valve can make the pump have the function of one-way oil supply. The whole hydraulic manifold structure is compact, reducing pipes, joints and pipe fittings, simplifying the installation project, and replacing pipes with oil holes, which is also helpful for energy consumption.
A few days ago, Krischnan told me privately that AAK's design idea was admired by their engineers. Now, people in the technical team respect him more when they see him, and what he does is more and more interesting.
AAK hydraulic manifold, reduces energy consumption by 20%, and you can also have a small try!
