3 pressure test standards of hydraulic valve block replaced 1 pressure test standard of , no longer worries about losing customers
is one of our old customers of hydraulic valves in . He purchases hydraulic cartridge valves from all year round. Recently, he suddenly asked me some technical parameters of hydraulic valve blocks. I was a little surprised. After further communication, I learned that he started to purchase hydraulic valve blocks for the first time last year, but failed. purchased a batch of hydraulic valve blocks from a manufacturer who just produced hydraulic valves for him in the past. Maybe this manufacturer didn't know enough about the hydraulic valve blocks. After 100 hydraulic valve blocks arrived, there was a problem after sales. According to the user's feedback, the pressure of the hydraulic valve blocks could not meet the system requirements, and the pressure was also unstable. Most hydraulic valve blocks were required to be returned. The manufacturer also said that these hydraulic valve blocks had been tested before leaving the factory. Now these hydraulic valve blocks are stacked in the warehouse. regretted it so much that he was sad all day long.
According to the hydraulic valve block drawings, sample photos, and videos provided by , I told him that the processing accuracy of the hydraulic valve block should still be flawed. Although the original manufacturer also did the pressure test, he may not understand that there are 3 types of hydraulic valve block pressure tests, or even he just completed the pressure test on the pressure test bench. This is a common problem in pressure test of most hydraulic valve block manufacturers, but never tests pressure like this.
2 weeks later, I sent 10 samples of hydraulic valve blocks according to his drawings. About 2 weeks later, Andy advised that when hydraulic valve block was installed, the pressure parameters were consistent with the system requirements, and it was smoother and had more stable pressure debugging than that of the original manufacturer. Users liked it very much. disposed of the hydraulic valve blocks in the warehouse and asked us to replenish 100 pieces as soon as possible to fill the inventory.
I told that the processing of hydraulic valve blocks will not be falsified in terms of accuracy first and finally in the pressure test stage of hydraulic valve blocks will not be sloppy. The pressure test is carried out directly in the hydraulic system, which is more consistent with the operating conditions than the test on the pressure test bench. At the same time, the test pressure is determined according to the working pressure of the system. However, most manufacturers cannot directly test the hydraulic valve block in the hydraulic system, and directly use the traditional process to test on the pressure test bench.
