Joakim, from Greece, got stuck when he purchased the hydraulic cartridge relief valve for the first time from China. One of their hydraulic motors needs a hydraulic cartridge relief valve. Joakim purchased it from a cartridge valve manufacturer in Ningbo. However, during the test run, the motor was damaged due to the abnormal pressure buffering function of the hydraulic cartridge relief valve, which was also blamed by the engineer. The original manufacturer was not confident to improve the pressure buffering function of the hydraulic cartridge relief valve. Joakim contacted me.
I sent two customer cases of how AAK optimized the buffering function of the hydraulic cartridge relief valve to Joakim. On the second day, he asked AAK to make samples. After 30 days, AAK sent 8 samples of hydraulic cartridge relief valve. 2 weeks later, Joakim told me that the customer approved their motor, especially their engineer was very satisfied with the pressure buffer function of AAK hydraulic cartridge relief valve. In contrast, 2 advantages come out: the hydraulic system is stable and the motor performance is improved.
AAK hydraulic cartridge relief valve, no impact trouble. The optimized hydraulic cartridge relief valve pushes the buffer spring at a constant speed, so that the time for the overflow pressure to rise from low pressure to high pressure remains constant. When the opening pressure is low, it gradually rises to the rated pressure, effectively reducing the impact of the moment when the motor rotates and starts.
1. AAK hydraulic cartridge relief valve is equipped with a differential valve spool with an orifice, and the annular bulge on the outer surface is used to connect the spring.
2. The buffer valve sleeve is inserted into the cavity of the differential valve spool. There is a buffer valve spool and an oil pipeline inside. There is a buffer valve spool throttle hole between the oil pipeline and the buffer valve spool. The two oil pipes inside the buffer valve sleeve are connected by two throttle holes.
3. The buffer valve sleeve and the buffer valve spool are sealed by the screw plug, and the two ends of the buffer spring are fixed in the buffer valve spool and the screw plug respectively. At the same time, the spring stiffness coefficient on the differential valve spool is greater than that of the buffer spring.
AAK hydraulic cartridge relief valve, no impact, 2 advantages, you can also try it!
