Caspar is from a hydraulic transmission equipment company in Canada. He has been in purchasing for 5 years, and it is very smooth. In the first half of this year, a batch of hydraulic transmission units they sold was complained by customers that they often had cavitation. The first judgment should be that the hydraulic cartridge pressure control valve in the hydraulic system is abnormal, but the engineer thought that the valve was from the SUN hydraulics and should not have problem. He subconsciously thought that the hydraulic pump that Caspar purchased from China had a leak. After the test, it was found that the pressure at the outlet of the pump was stable. After checking one by one, only hydraulic cartridge pressure control valves from SUN were not checked, but the valve parameters were normal. The engineer was puzzled. After communicating with each hydraulic component manufacturer of the equipment, Caspar came to the conclusion that this SUN hydraulic cartridge pressure control valve may not be suitable for this hydraulic transmission equipment. However, none of the manufacturers of hydraulic cartridge pressure control valves can solve the hidden danger of cavitation, so they can only turn to SUN for help. But SUN was not interested in customizing small quantities. Caspar was helpless and anxious.
Caspar found AAK while browsing Google. According to our background trace, he stayed on AAK website for more than 30 minutes, and left a message: Is the cavitation of the equipment caused by the hydraulic cartridge pressure control valve in the system? This needs to be specifically analyzed, according to SUN standard part number, hydraulic schematic diagram, equipment technical parameters, and used scenarios, AAK engineer believed that the SUN hydraulic cartridge pressure control valve of this model does not meet the special requirements of the equipment. AAK can sample the hydraulic cartridge pressure control valve, and it is 90% sure to solve the cavitation complaint. After 45 days, 10 samples of hydraulic cartridge pressure control valves were sent out.
Last week, Caspar emailed that there was no cavitation after AAK hydraulic cartridge pressure control valve was used. The customer was very satisfied, but still had to continue to observe for several months. I told Caspar that AAK hydraulic cartridge pressure control valve had eliminated the cavitation hazard of the equipment in terms of function. As long as AAK hydraulic cartridge pressure control valve is within the service life, cavitation will not occur.
How did this hydraulic cartridge pressure control valve replace SUN standard parts in function? In AAK hydraulic cartridge pressure control valve, there are two valve spools, separated by a spring, which is fixed in between 2 valve cages. The set value of overflow pressure can be set by adjusting the valve cage. At the same time, there is a damper between the two valve spools, which can provide positive damping of the hydraulic system. The valve can limit any input pressure in the inlet pipeline, prevent impact or pressure fluctuation when the actuator changes direction or stops suddenly, and also allow oil to enter the low pressure pipeline to supplement the oil drainage or any discharged flow. Its two-way cross type function can deliver the discharged oil to other pipelines to ensure the actuator is refilled with oil and eliminate cavitation.
AAK customized hydraulic cartridge pressure control valve has more functions than SUN, and you can also have a small try!
