Caspar is from a hydraulic transmission equipment company in Canada. He has been in purchasing for 5 years, and it is very smooth. In the first half of this year, a batch of hydraulic transmission units they sold was complained by customers that they often had cavitation. The first judgment should be that the hydraulic cartridge pressure control valve in the hydraulic system is abnormal, but the engineer thought that the valve was from the SUN hydraulics and should not have problem. He subconsciously thought that the hydraulic pump that Caspar purchased from China had a leak. After the test, it was found that the pressure at the outlet of the pump was stable. After checking one by one, only hydraulic cartridge pressure control valves from SUN were not checked, but the valve parameters were... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

AAK hydraulic valve block, from a five axis CNC machining center, is milled with a thread milling cutter, completely replacing the traditional radial drilling machine processed with a formed tap, and the thread surface roughness value is Ra1.6μm. The traditional Ra is at 12.5μm. Ra alone has increased sevenfold. Archie purchased AAK hydraulic valve blocks, which not only stopped losing more than 30,000 dollars, but also made an additional profit of more than 10%.

For the hydraulic valve block with conical pipe thread, the pipe thread cannot completely seal oil, which is an industry problem. The vast majority of hydraulic valve block manufacturers use traditional radial drilling machines and formed taps for processing. The surface roughness of their threads is a "mine",...

AAK HYDRAULIC VALVES

Senon is from a Spanish hydraulic equipment company and has been responsible for the procurement of hydraulic valves for 3 years. At the end of last year, their customer customized two sets of hydraulic power units for ocean ships, and needed to customize the hydraulic cartridge counterbalance valves. Senon chose a hydraulic counterbalance valve manufacturer who has cooperated for 3 years to make samples. During the equipment commissioning, it was found that the pressure supply was unstable and the hydraulic system was tested separately, but there was no abnormality. The boss questioned the team's performance. Senon felt that there was a hidden danger in the original design of the hydraulic cartridge counterbalance valve, but the engineer thought that the function of the purchased...

AAK HYDRAULIC VALVE

Last week, Marc and I talked about a processing detail of hydraulic manifolds. By the way, I asked him why did you choose AAK for your first hydraulic manifold supplier 4 years ago. He just sent me 1 word: trust.

These days, I wonder: What is the core of AAK hydraulic manifolds? Is the manufacturing quality good in China? It must be good. The problem is that your hydraulic manifold is of good quality. How can you make customers think it is really good, and really reliable? I think they finally decided to place order with AAK because they trusted me, so I feel that trust is the key to a deal for the grassroots and our small bosses of hydraulic manifolds.

AAK hydraulic manifold is not a brand. I don't have a brand. It is neither a marketing, I don't study... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVE

Devante is from a hydraulic equipment company in Spain. He has been purchasing for 8 years and cooperating with AAK for 3 years. In June last year, a batch of hydraulic cylinders of their company were complained of telescoping jitter. During after- sales service, it was judged that the hydraulic cartridge relief valve of the hydraulic system was abnormal. After disassembly, it was found that the spring elasticity in the valve body was out of function. The manufacturer of the hydraulic cartridge relief valve thought that the high working frequency of oil cylinder caused spring failure. It could be replaced for free for good cooperation, but the complaints were increasing later. The boss was not satisfied with the hydraulic cartridge relief valves purchased by Devante this time, and Devante... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Sulaiman comes from Brazil, and their hydraulic cylinder business is mainly with the local engineering machinery manufacturers. In the second half of last year, a batch of their hydraulic cylinders used on cranes almost caused an accident. The root cause was the hydraulic cartridge counterbalance valve, which was lack of function. During the construction of the crane, the hydraulic oil pipe burst suddenly, and the crane dropped rapidly to the ground. During on-site inspection, it was found that the oil cylinder operated normally, and the hydraulic system also complied with the principle. The local manufacturer of the hydraulic cartridge counterbalance valves reported that there was no problem with the manufacturing quality. After 1 week, there was no progress in the after-sales plan. The... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Lewis is from a Greek hydraulic equipment company. He has been purchasing hydraulic components for 3 years and has been successful. At the beginning of the year, their customer had a trial order for 3 wheel loaders and needed hydraulic cartridge needle valves. Lewis chose a hydraulic cartridge needle valve manufacturer in Greek. After using the equipment for 3 months, the customer reported that one of the equipment failed to rise, which should be due to the abnormal hydraulic system. After disassembly, it was found that the spool of the hydraulic cartridge needle valve was stuck in the radial direction, which affected the axial movement of the screw. The root cause was that the coaxiality of the spool and the cage of the hydraulic cartridge needle valve was inconsistent. The manufacturer... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Alvis is from Norway and has been in contact with AAK for 1 year. There were some inquiries for hydraulic manifold blocks, but no actual order. It was not until December last year that the trust door was completely opened. It took him 6 months for a special hydraulic manifold block, but it didn't work. AAK solved the problem with the first sample.

A set of hydraulic manifold designed by Alvis will be exhibited in America. He selected a local hydraulic manifold block manufacturer that has cooperated for 3 years to try the sample, but the hydraulic system is unstable. The manufacturer advised that this hydraulic manifold block has many feedback oil circuits and control oil circuits, and the oil circuits is composed of small deep holes. The diameter of the damping hole is less... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Timothy is from a Greek hydraulic equipment company, and has been in the company for 5 years. At the beginning of this year, they launched a new hydraulic injection molding machine, focusing on energy-saving and consumption reduction. The hydraulic manifold for the machine is designed internally by them, and they chose a hydraulic manifold manufacturer who has cooperated for 3 years to try samples. Although the equipment debugging is smooth, the energy consumption has not been significantly improved. Timothy guessed that the hydraulic manifold was not efficient, but he had no idea about optimization. The hydraulic manifold manufacturer has solution neither. Timothy also tried to contact more than 10 hydraulic manifold manufacturers. They either have no reply or have to find out the reason... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Diego, from Spain, has been engaged in the procurement of hydraulic valves for 5 - 6 years, and has been successful. But the hydraulic cartridge needle valves purchased from a local manufacturer stumped him. At the beginning of last year, their company urgently purchased a batch of hydraulic needle valves to be installed on a batch of hydraulic equipment that customers urgently need. Diego purchased the hydraulic needle valves from a local manufacturer. 3 months after the equipment was sold, the customer complained that the equipment was unstable. After testing the hydraulic system, it was found that when the hydraulic needle valve spool was in the fully closed position, it was stuck radially, because the coaxiality deviation between the valve spool and the valve body was 2μm, 3μm, or 4μm....
