A little fluctuation is allowed when the ball valve is opened and closed, but it can immediately return to the set pressure. After the commissioning of ball valves is completed and they are in the correct opening/closing position, the handles should be removed and placed in a convenient position to prevent unnecessary trouble caused by misoperation of irrelevant personnel. Before all pressure gauges are formally used, please exhaust the air in the pressure measuring pipeline; Matters needing attention in adjustment and detection of each control valve on the test bench: Check whether all valves, valve blocks, pipelines, etc. are installed correctly according to the hydraulic principle and assembly drawing; The butterfly valve at the oil return port must be in the open position; Before the formal test run, flush and exhaust operation should be carried out first; The signal of the proportional valve is 4 ~ 20mA, and the specific adjustment and use need the cooperation of the electrical engineer. The set pressure of each pressure reducing valve shall be adjusted according to the marked value on the hydraulic schematic diagram. And carry out continuous step-up and step-down tests before setting;
