How to adjust the press hydraulic system

The hydraulic system is the core component of the press, and its adjustment and optimization have an important impact on the performance and efficiency of the press. The following will introduce and answer questions from three aspects of the adjustment method, adjustment steps and adjustment precautions of the hydraulic system.

First, the adjustment method of hydraulic system

1. Adjust the working pressure of the hydraulic pump: the hydraulic pump is the power source of the hydraulic system, and the adjustment of the working pressure directly affects the working effect of the hydraulic system. Adjusting the working pressure of the hydraulic pump can be achieved by adjusting the opening pressure of the relief valve. Under normal circumstances, the working pressure of the hydraulic pump should be adjusted according to the working requirements of the press to ensure that the hydraulic system can provide sufficient working pressure.

2. Adjust the stroke of the hydraulic cylinder: the hydraulic cylinder is the actuator of the press, and the adjustment of its stroke directly affects the working efficiency and working accuracy of the press. Adjusting the stroke of the hydraulic cylinder can be achieved by adjusting the limit valve of the hydraulic cylinder. Under normal circumstances, the stroke of the hydraulic cylinder should be adjusted according to the working requirements of the press to ensure that the hydraulic cylinder can complete the required working stroke.

3. Adjust the working pressure of the hydraulic valve: the hydraulic valve is the control element of the hydraulic system, and the adjustment of the working pressure directly affects the control effect of the hydraulic system. Adjusting the working pressure of the hydraulic valve can be achieved by adjusting the opening pressure of the pressure regulator. Under normal circumstances, the working pressure of the hydraulic valve should be adjusted according to the working requirements of the press to ensure that the hydraulic valve can work normally.

Second, the hydraulic system adjustment steps

1. Determine the adjustment objective: Before the adjustment of the hydraulic system, it is first necessary to clarify the adjustment objective, that is, the working requirements and effects to be achieved. Only when the adjustment goal is clear, can the adjustment be targeted.

2. Adjust the working pressure of the hydraulic pump: according to the working requirements of the press, gradually adjust the working pressure of the hydraulic pump by adjusting the opening pressure of the relief valve until the required working pressure is reached.

3. Adjust the stroke of the hydraulic cylinder: According to the working requirements of the press, gradually adjust the stroke of the hydraulic cylinder by adjusting the limit valve of the hydraulic cylinder until the required working stroke is reached.

4. Adjust the working pressure of the hydraulic valve: According to the working requirements of the press, gradually adjust the working pressure of the hydraulic valve by adjusting the opening pressure of the pressure regulator until the hydraulic valve can work normally.

5. Inspection and testing: After completing the adjustment of the hydraulic system, it is necessary to check and test the hydraulic system to ensure that the hydraulic system can work normally and meet the working requirements of the press.

Third, the adjustment of the hydraulic system precautions

1. Be careful in the adjustment process to avoid damage or failure of the hydraulic system caused by operational errors.

2. Pay attention to safety when adjusting to ensure the safety of operators and equipment.

3. Before adjustment, the hydraulic system should be comprehensively inspected to ensure that the various components and connections of the hydraulic system are not loose, oil leakage and other problems.

4. Adjust according to the working requirements of the press to avoid excessive adjustment or insufficient adjustment.

5. Check and test after adjustment to ensure that the hydraulic system can work normally and meet the working requirements of the press.
