| Message: | Andrew is the purchasing director of VIS Hydraulics in Italy and an old friend of AAK. He has cooperated with AAK for more than 4 years. One morning in October, I received an email from Andrew with the subject of "a big trouble". It is the first time that I received such an emotional email from Andrew. After reading, it turned out that the pressure of a hydraulic power system of their company was not enough, and the customer complained. The root of the problem is that the hydraulic threaded cartridge valve and hydraulic valve block does not match each other. The owner asked him to solve the problem within a month.
After communication, it was learned that the hydraulic threaded cartridge valve and the hydraulic valve block purchased by Andrew were not produced by the same manufacturer. Now both manufacturers do not admit that it was their own problem. The hydraulic threaded cartridge valve manufacturer said that the pressure of the hydraulic system was slow due to the processing accuracy of the hydraulic valve block, while the hydraulic valve block manufacturer said that the hydraulic threaded cartridge valve had leakage, resulting in insufficient flow. Andrew failed to communicate for several times and thought of AAK. During so many years of cooperation, only AAK hydraulic valve has no complaint. He hopes that AAK can help him find out what the problem is.
Andrew sent us the design drawings of the hydraulic threaded cartridge valve and hydraulic valve block. After analysis, AAK engineers found that the probability is that the design of the hydraulic valve block is unreasonable, the flow area of the through hole designed is not enough, and the direction and position of the oil inlet and outlet are not optimal, resulting in insufficient pressure of the whole hydraulic system. Andrew asked the hydraulic valve block manufacturer to design and produce, but the manufacturer needs 2 months to complete it, while the time given by his owner is only 1 month. |
