This utility model discloses a semiconductor liquid testing device, which can be divided into two states. In the liquid supply state, the pneumatic pump works normally in conjunction with the pneumatic valve A to draw liquid from the liquid tank and deliver it to the test supply point. In the liquid supply end state, after the liquid in the liquid tank is emptied, the pneumatic valve B is closed and the manual valve A is opened to release the liquid in the pipeline between the pneumatic pump and the liquid tank. At the same time, the manual valve B is opened to discharge the liquid in the pipeline between the pneumatic pump and the pneumatic valve C, including the pipeline between the pneumatic pump and the pneumatic valve B. After emptying, it avoids the impact on the pneumatic pump caused by the liquid flowing back down when the pneumatic pump is stopped due to the remaining liquid in the pipeline when the liquid is pumped vertically upward. The function of the manual valve D is to depressurize the filter device before operation, and the function of the manual valve E is to drain the liquid in the filter device after operation.
