Mason is from a hydraulic equipment company in India. It has been 3 years since he purchased hydraulic cartridge valves from local hydraulic cartridge valve manufacturers in India. At the beginning of this year, their company developed a hydraulic crane and needed hydraulic cartridge counterbalance valves. They chose a local hydraulic counterbalance valve manufacturer who has cooperated for 5 years to make samples. During the equipment debugging, it was found that the crane vibrated during the descending process and the descending speed was abnormal. The after-sales servicer believed that the hydraulic cartridge counterbalance valve was abnormal. After the original manufacturer inspected the hydraulic counterbalance valves, all parameters were in accordance with the drawing parameter requirements. After internal discussion, it was concluded that the hydraulic counterbalance valve must be optimized, but the original manufacturer had no ability to do it. The boss asked Mason to look for overseas suppliers of hydraulic cartridge counterbalance valves. A week has passed, the manufacturer of the hydraulic counterbalance valve has not been determined yet. The boss was not satisfied. Mason began to worry.
Mason found AAK on Google, stayed on AAK website for 23 minutes, and left a message: Can AAK design a hydraulic cartridge counterbalance valve to solve the instability and abnormal speed of the hydraulic crane during the descending process? For those who stay on AAK website for a long time, no matter which country they come from, as long as they are not hydraulic cartridge valve manufacturers, I will do my best to help. After communication, I learned that Mason was embarrassed to purchase hydraulic cartridge counterbalance valves. According to his system schematic diagram, hydraulic cartridge counterbalance valve drawing and crane working video, AAK engineer had a basic idea. 3 days later, AAK began to sample. After 40 days, AAK sent 6 hydraulic cartridge counterbalance valve samples.
A month later, Mason emailed that after the new hydraulic cartridge counterbalance valve designed by AAK was used, the hydraulic crane did not shake during the load lowering process, and the speed was even. Their colleagues were very confident in the promotion of the cranes, and the boss was also happy.
AAK does not use the traditional route to optimize the hydraulic cartridge counterbalance valve. According to the system diagram of the equipment and the abnormality of the crane, the hydraulic cartridge counterbalance valve is composed of valve body, valve seat, main valve spool, pilot valve spool and pilot mechanism. First, connect the valve seat with the valve body to establish a connected first channel. The extended end of the valve seat is connected with the pilot mechanism to establish a second channel. The main valve spool adopts sliding setting, and is equipped with throttling groove and orifice. Then the valve seat cavity is divided into 3 cavities, one end of the valve spool is in the inner cavity, and the other end is connected with the pilot mechanism. The valve spool is flexible, controllable and free from load interference.
Last week, Mason told me privately that his boss decided to increase the purchase of hydraulic cartridge valves from China and give him more authority. He was more confident in his work
AAK hydraulic cartridge counterbalance valve, is not only a surprise, you can also have a small try!
