1. Product Introduction:
WS-C-25 vertical hydraulic impact test system adopts hydraulic lifting, which has the advantages of smooth lifting and low noise. Air spring vibration reduction device reduces the impact on the surrounding environment. The high-pressure hydraulic brake device is used to overcome the additional impact of mechanical brakes on the test sample, ensuring reliable braking and no noise. At the same time, the WS-C-25 vertical hydraulic impact testing system considers multiple safety protection measures in its design, such as power-off protection function, safety interlock protection device, oil source standby unloading, etc., to ensure that the equipment will not endanger personnel, test specimens, and equipment safety due to accidental falls on the workbench during operation
The WS-C-25 vertical hydraulic impact test system can perform conventional and high-energy half sine wave impact tests, meeting standards such as GB/T2423.5-95, GJB150.18A-2009, GJB360.23, GJB548B-2005, IEC68-27-2008, etc

III. Technical Parameters
4. Working principle
The structure of the WS-C-25 vertical hydraulic impact test system is shown in Figure 3. It lifts the worktable to the set height by hydraulic drive and cylinder lifting, with low-pressure oil supply for the lifting part and high-pressure oil supply for the braking part. Its working principle is that the hydraulic system supplies oil to the lifting cylinder. After lifting the table and the test sample to the desired height, the brake oil circuit is opened, instantly locking the table. Then the hydraulic system changes direction, and the lifting cylinder piston rod descends. When the lifting cylinder piston rod descends to the lowest point, the hydraulic system stops supplying oil, the locking oil circuit is released, and the table falls freely. It collides with the waveform generator installed on the base, generating an impact waveform. The sensor installed on the table collects the waveform signal generated by the impact and transmits it to the analysis software, which displays it on the computer monitor. At the same time, the worktable will rebound, and the braking device will instantly activate to lock the worktable, avoiding secondary impact and completing the first impact test
