AAK redesigned the hydraulic check valve, solving the leakage problem
At the beginning of last year, Lawrence sent an email to ask for help. He is a purchaser of a hydraulic equipment company in Italy and has cooperated with AAK for 2 or 3 years. Almost all of the orders are a small number of hydraulic check valves with high requirements. When encountering problems, he always asks for help from AAK, and AAK is also happy to help him. After several rounds of email communication, it turned out that the power unit for controlling the hydraulic lifting column produced by their company had a customer complaint 3 months after sales. Their engineers found a leak on the valve block of the power unit, that is, around the valve hole equipped with the hydraulic pilot operated check valve. It is preliminarily judged that the leakage should be caused by the wear of the seal of the hydraulic pilot operated check valve. However, after dismantling the hydraulic pilot operated check valve, it is found that the sealing ring is intact. After Lawrence communicated with the original manufacturer of hydraulic pilot operated check valve, they both thought that there should be no problem with the hydraulic pilot operated check valve or valve block, because the test data before shipping were qualified. The leakage problem should be caused by the wrong operation of the installation personnel of their company. Lawrence seemed to understand because it is true that the test result of the hydraulic pilot operated check valve originally shipped was OK. Lawrence asked their engineers to reinstall it. As a result, it worked normally and everyone thought the problem had been solved. But 3 months later, the same problem happened again, and the customer could not accept and requested to return goods. The boss was very angry and asked Lawrence and the engineer to completely solve the leakage problem of the hydraulic pilot operated check valve. This is why Lawrence emailed to AAK for help. AAK engineers analyzed according to the valve block integration diagram and the drawing of hydraulic pilot operated check valve provided by Lawrence. There is an assumption that the frequent vibration of the power unit of the hydraulic lifting column affects the stability of the installation of the hydraulic pilot check valve. Following this idea, it is found that the hole depth of the threaded socket integrated with the valve is not enough, which leads to the loosening of the jack position of the hydraulic pilot operated check valve. This problem can only be solved by adjusting the depth of the jack, increasing the thread torque of the hydraulic pilot operated check valve and increasing the bonding area between the valve and the hole. The next day I emailed Lawrence the idea of our engineer's. If we want to verify this idea, we can only make samples. One month later, AAK sent the redesigned hydraulic pilot operated check valve and integrated valve block to Lawrence. Last week, Lawrence sent an email saying that after the hydraulic pilot operated check valve and valve block redesigned by AAK were installed on the equipment, so far, the hydraulic lifting column has been used without abnormality. The customer was very satisfied that they finally solved the leakage problem of the hydraulic pilot operated check valve at one time. His boss also appreciated Lawrence for helping the company solve the after-sales problem. AAK hydraulic pilot operated check valve is cleverly designed to easily solve the leakage problem. Welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pilot-operated-check-valves- aak172 Contact:

AAK Hydraulic Manifold Blocks Same Accuracy of 2 Opposite Sides
Last week, Kedma from Israel left a message on the hydraulic manifold manufacturer AAK website: 1. We need to customize a hydraulic manifold block, for each 2 opposing faces of the 6 faces of the manifold block, its accuracy must be the same. 2. This hydraulic manifold block is intended for military equipment. If it does not meet the requirements, please do not provide a quotation. I saw this message and did not reply directly. But instead, I asked Kedma, ‘You should have checked with many hydraulic manifold manufacturers, right? And most of these hydraulic manifold manufacturers gave no reply or said No.’ Kedma agreed with my guess and asked me how I found out. I told Kedma that most hydraulic manifold manufacturers in China are not confident, especially when it comes to military products, they are a bit scared. Moreover, Kedma has special requirements, and these hydraulic manifold manufacturers do not want to cause trouble, and some hydraulic manifold manufacturers do not have the ability to do so. Kedma seems to be interested in AAK and asked me how much time and cost it would take to customize this hydraulic manifold block, and how can AAK ensure that the accuracy of the 2 opposing faces of the hydraulic manifold block must be consistent? I said, before providing a quotation and development, let's first watch a video of how AAK processes hydraulic manifold blocks. From the video, it can be seen that the key points are the 3 steps: 1. The processed hydraulic manifold block should be properly positioned to ensure centering. 2. The processed hydraulic manifold block should be securely fixed to ensure no displacement 3. The 2 opposing faces of the hydraulic manifold block are processed and milled simultaneously. The double-sided milling machine is a perfect match for Kedma's special requirements for hydraulic manifold blocks. It is driven by the spindle and simultaneously drives 2 symmetrical milling cutters. At the same speed and milling depth, the surface roughness of the 2 opposing faces of the hydraulic manifold block is also synchronously controlled. The 2 symmetrical milling cutters are capable of cutting 360 degrees without dead angles in front and back, up and down, left and right. The processed hydraulic manifold blocks do not need to be flipped, avoiding secondary positioning errors. Most hydraulic manifold manufacturers process the hydraulic manifold blocks by one face to another, which not only has low efficiency and unstable accuracy, but also cannot achieve the same accuracy of hydraulic manifold blocks on 2 opposite sides. AAK hydraulic manifold blocks, processed on 2 opposite sides simultaneously, with no errors, you can also try it out.
