Margaret is from a hydraulic equipment company in the United States. At the end of last year, some of their drilling rigs were complained by customers that they were unable to work. The problem was the leakage caused by the wear of the hydraulic flow control valves. The original hydraulic flow control valve manufacturer said that due to long-time high-pressure and high-frequency operation, the wear of the valve body is difficult to avoid, so the hydraulic flow control valves can only be replaced. After half a year, the fault occurs again, and it seems that the hydraulic flow control valves can only be replaced once every half a year. After the boss knew about it, he was not satisfied with this high frequent after-sales service. He asked Margaret to find a new hydraulic flow control valve manufacturer, and added the parameter requirements of high pressure resistance in the inquiry.
In the first round, Margaret contacted with more than 10 hydraulic valve suppliers that she was satisfied with in the past, and only 3 said that they could have a warranty period of half a year to 1 year under high pressure. Margaret should not be satisfied with this reply either. After being introduced by one of our old customers, she contacted me. I suggest that she use durability to measure the service life of hydraulic flow control valves. After communicating with their engineers, she requested that the durability of this hydraulic flow control valve be more than 1.5 million times.
AAK engineers judged that according to their working conditions and pressure requirements, the material selection of this hydraulic flow control valve is very important, especially the valve body material. After 40 days, AAK sent 10 samples of hydraulic flow control valves. More than 2 months later, Margaret emailed that the durability tests of 3 factories and AAK hydraulic flow control valves had failed. Before sending samples, our engineers tested each hydraulic flow control valve, and the durability of 1.5 million times is unlikely to fail. After checking with Margaret, it was learned that their boss specially asked the engineer to increase the durability test from the original 1.5 million times to 2million times.
Margaret said that the other 3 factories have given up re testing, and asked whether we are willing to continue testing?
AAK is most willing to do what its peers are unwilling to do. Three months later, the samples of the hydraulic flow control valves were sent again. Last week, Margaret said in an email that AAK hydraulic flow control valves passed the test and is the only manufacturer that can adhere to the samples for half a year. Their teams are convinced that AAK is obsessed with manufacturing quality. The boss was also very satisfied that she found a professional hydraulic flow control valve supplier like AAK.
Over the past 13 years, AAK technical team has gained an experience that every customer thinks that the problems they encounter are individual and unique. In fact, we have already solved them here. Why do you have personalized questions? That's because none of your peers can help you solve it, let alone promise. During the test sample period, AAK engineers worked for more than 14 hours every day. After repeated defeats, they finally determined 3Cr3Mo3W2V hot work die steel as the valve body material and made special treatment on heat treatment. The mechanical stress is more than 10 times that of other steels. The hardness, strength, wear resistance, stability and thermal conductivity are completely consistent in the whole material section, so as to ensure that the hydraulic flow control valves can pass the test of 2million times under high pressure.
AAK hydraulic flow control valve, 2 million times of service life, you can also have a small try!
