Hydraulic press system pressure is not high reason

In the process of using the hydraulic press, some people reflect that their hydraulic press system pressure is not high, then why the hydraulic press system pressure is not high, because of what reasons? So let me explain to you why.

Hydraulic press system pressure is not high reasons:

The first point: the main pump of the hydraulic machine has been worn, resulting in serious brain leakage and low system pressure rise

The second point: the pressure regulating safety valve group is the main component of the control system pressure, such as failure will affect the system pressure rise is not high.

The third point: the hydraulic master cylinder is the actuator of the system, if the internal leakage of the master cylinder is serious or the string cavity, the system pressure is not high, which is not likely for the new hydraulic press, and for the old long-term use of hydraulic press, this factor cannot be ruled out.

Fourth point: the filling valve leaks, and the oil in the upper chamber of the master cylinder flows back to the filling tank.

Fifth: The control oil circuit of the unloading valve of the hydraulic press leaks, causing fault symptoms.

Sixth: oil press steel ball check valve wear, reverse leakage leads to low pressure rise.

Then the above points are the reasons why the pressure of the hydraulic press system is not high, if it is found that the action of the hydraulic press becomes slow, it is necessary to seriously find the reason, the same as the exclusion, do not let the equipment work with disease. Regular inspection of equipment for safety hazards, regular maintenance and maintenance can extend the life of the machine.
