Customer reversed internal and external leakage of the hydraulic directional control valve, causing vibration, AAK new design solved it all at once Stephen is from Hi-Force hydraulic equipment manufacturing company in the UK. In the second half of last year, he was promoted to the purchasing manager of Kuala Lumpur Branch due to his excellent work. Within a week of taking office, he met with complaints. A batch of their hydraulic cylinders were noisy and vibrated seriously during operation. The after-sales engineer failed to solve the problem within 3 days. The user was not satisfied. Stephen was a little worried. Stephen browsed an article of AAK on Google: "change the design of the hydraulic directional control valve, the vibration disappeared, and AAK eliminated the Canadian factory at zero cost", and left a message: how to solve the noise and vibration of the hydraulic cylinder? After reading this message, I roughly judged that either the hydraulic directional control valve used had problems or the original design had hidden dangers. We asked Stephen to provide the hydraulic system schematic diagram and design drawings, and AAK engineer judges that the working principle of the hydraulic cylinder is reasonable, only by checking on site can we find out the source of the vibration, and then no news from Stephen. 2 weeks later, Stephen emailed that according to the last case that AAK solved the vibration of the hydraulic cylinder, they also added a triangular throttling groove to the hydraulic direction control valve, but after installation, the hydraulic cylinder still vibrated. Their engineers said that AAK solution was a lie. I was speechless and didn't want to explain anything, so I ignored him. 3 days later, Stephen emailed us again, and sent a video of the hydraulic cylinder working and asked our help to check. AAK engineers found that the hydraulic cylinder will emit rhythmic noise and vibration whenever the load drops in the actual work, and preliminarily judged that there is a problem with the hydraulic direction control valve. AAK technical team discussed again according to the drawings, the working principle diagram of the hydraulic cylinder and the working video of the hydraulic cylinder, and confirmed that the problem lies in the hydraulic direction control valve. I told him that AAK could redesign the hydraulic directional control valve and asked him to send us samples of the original hydraulic directional control valve. Stephen may have no choice but promised. 5 days later, we received the sample of the original hydraulic directional control valve, which confirmed the judgment of our engineers that the internal leakage and external leakage of the original hydraulic directional control valve was reversed. 1 week later, AAK sent the newly designed external leakage type hydraulic directional control valve. Stephen informed by email that the noise and vibration problems of the hydraulic cylinder had been
Kayden, from AH Garner company in the UK, has successfully purchased hydraulic valve blocks in Ningbo in recent years, and has cooperated with AAK on some high requirements hydraulic valve blocks for many years. He sent an email at the end of last year: I need AAKâ??s help. After communication, we learned that a new hydraulic equipment of their company was complained by customers about oil leakage in about 3 months. After inspection, their after-sales personnel found that when the equipment is switched with high-speed and high-frequency action under high pressure, the small O-ring of the cover plate of the hydraulic valve block is prone to oil leakage. The engineer asked Kayden to find the original supplier to replace the hydraulic valve blocks or cartridge valves. Unfortunately, Kayden purchased the hydraulic valve blocks and threaded cartridge valves from two factories. The manufacturer of the hydraulic valve blocks replied that the thread size accuracy of the cartridge valves did not meet the standard and caused oil leakage, while the cartridge valve manufacturer said that the accuracy of the hydraulic valve blocks did not meet the standard. The hydraulic valve blocks and cartridge valves have passed the inspection. How can there be a problem as soon as they are assembled on the equipment? Kayden suspected that the design of the hydraulic valve block was flawed, but the engineer thought the design drawing was in line with the principle. The customer didn't receive the solution, and complained to the boss, who asked Kayden to completely solve the oil leakage problem of the hydraulic valve blocks within 30 days. Now Kayden was stumped and didn't have a clue. I asked Kayden to send us the drawings of the hydraulic valve block and cartridge valve, and system principles. AAK engineers found no problems after analysis. Our engineer asked Kayden to provide the video after the equipment was started up. Combined with the system schematic diagram and equipment fault video, our engineer judged that the position of installing O-ring at the interface of hydraulic valve block and cartridge valve was inappropriate. If the position of the O-ring is lowered, and the cover plate O-ring is completely free of oil, install and fasten the cartridge valve cover plate, and produce the hydraulic valve block and cartridge valve in a same factory, the oil leakage problem of the hydraulic valve block may be solved completely. Kayden seems to have seen the dawn and asked AAK to make samples. After 25 days, AAK sent out the integrated hydraulic valve block sample. A few days ago, Kayden emailed us that it has been 3 months since the hydraulic valve block was replaced with AAK samples, the equipment works normally without oil leakage. Kayden told me that AH Garner engineer admired AAKâ??s strictness in details. It is so obvious, why didn't he find such an obvious problem?
When I opened the mailbox this morning, I saw a reorder for 500 pilot hydraulic relief valves from Jimmy. He mentioned that the pilot hydraulic relief valve designed by AAK had been used for 2 years and without any complaints. Jimmy is a purchaser of American company Vickers, responsible for the purchasing of hydraulic parts. 2 years ago, his company encountered a complaint from customer for a hydraulic pump. The customer complained that it screamed after being used for a period of time. After dissecting, their engineer found that there was a problem with the hydraulic relief valve in the hydraulic pump. The owner asked Jimmy to solve the problem as soon as possible. Jimmy sent the hydraulic relief valve back to the original supplier, but the supplier replied that the inspection result was good. Maybe the problem happened during installation. Jimmyâ??s engineers tested the samples by themselves and found that there was no problem with the hydraulic relief valve, but there was also no problem with the installation method and operation. Now Jimmy is depressed. The owner is pushing for status, but he has no clue. He contacted with several local hydraulic valve manufacturers in the United States, and they all replied that there was no problem on the hydraulic relief valve. One day, after browsing AAK website (www.aakindustry.com) in Google, Jimmy sent an email asking if AAK could help analyze the reason. We replied that it would be better for engineers to have video communication on site Jimmy decided to ask Vickers engineers to make a video with AAK engineers the next morning. After more than half an hour of observation, AAK engineers found that once the pressure oil at the inlet, outlet and control port of the hydraulic relief valve fluctuated, it would produce a scream. We got their original samples and drawings, as well as the working parameters of the hydraulic pump. After 15 days, AAK sent a sample of the pilot hydraulic relief valve. A week later, Jimmy e-mailed us that AAK hydraulic relief valve was installed and tested on site for 24 hours, and there was no scream. Jimmy wondered why there was no scream when AAK hydraulic relief valve was used. AAK engineers analyze the cause from the hydraulic impact. After the hydraulic pressure impacts the main valve spool in the hydraulic relief valve, the pressure oil converges through the check valve, resulting in fluid impact and fluctuation, causing the hydraulic relief valve to oscillate, resulting in the instability of the pressure oil at the outlet of the hydraulic pump. Because the pressure oil output by the pump itself has pulsation, the pressure oil output by the pump will fluctuate strongly and arouse the vibration of the hydraulic relief valve. For the natural frequencies of the two hydraulic relief valves are the same, it causes the resonance of the relief valve and the scream occurs.
AAK hydraulic pressure valve has no horn hole. In Ningbo, the hydraulic valve production base, few factories are sure to solve the horn hole. AAK uses automatic programming software to program and upgrade the processing technology of hydraulic valve cavity hole. The geometric tolerance of each hole is within 0.02mm. At the same time, small fillet is used to replace the R angle of our peers to transition, which completely avoids the horn hole. Most hydraulic valve manufacturers use manual programming to design the geometric tolerance of cavity hole, which is prone to human error and can not be corrected. At the same time, due to the limitation of operation methods, the transition angle between small holes in the hydraulic pressure valve generally adopts the R angle for transition, which is easy to artificially leave a small space that is not easy to detect, so the horn hole will probably appear. After the hydraulic pressure valve is used for a period of time, the horn hole is easy to leak. What's more troublesome is that the oil stain outside the hydraulic pressure valve is easy to enter the valve spool and damage the whole hydraulic system. Adair, a hydraulic valve purchaser in Scotland, had many contacts with AAK hydraulic valve before, because he pursues low price, there is no cooperation between us. In July this year, he placed an order for hydraulic pressure valve worth 80,000 US dollars to a hydraulic valve manufacturer in Ningbo. 2 months later, the quality of the hydraulic pressure valve failed to meet the standard every time. Adair realized that even if it took another 2 months, the sample still could not be approved. Adair accidentally saw an article from AAK about "horn hole" on the B2B website, he further sourced until he got to the AAK website: www.aakindustry.com, he realized that it was the hydraulic valve manufacturer he had been contacting. When we received Adair's email, we understood the problems and causes of his hydraulic pressure valve. 3 days later, we received the hydraulic pressure valve samples that he asked the original hydraulic valve manufacturer to send, we found that the processing coaxiality of the cavity hole diameter of the combined holes of these hydraulic pressure valves was between 0.03-0.05mm, and there were tool connecting traces at the transition R angle. After we took the video and sent it to him, he understood why the samples of the original hydraulic valve manufacturer were always not approved. After receiving the video, Adair transferred the order of this hydraulic pressure valve to us AAK hydraulic valve the next day. At the same time, Adair also joked that you found the problem, but not means that you are able to solve the problem. How does you AAK hydraulic valve do and make me believe that you can 100% solve these hidden problems.
