Analyze the reasons why the pressure of the hydraulic press does not come up

Recently, some customers have reported why the hydraulic press sometimes does not come under pressure. Today, Shanghai WORLD Press Machine will explain the reason to you.

(1) Common sense errors. For example, if the oil in the tank is insufficient, replace the hydraulic oil, connect the three-phase voltage, and the pressure regulating valve does not adjust the pressure. This usually occurs when the hydraulic press is first used.

(2) Oil leakage. First check the surface of the machine for obvious signs of oil leakage. If not, then the piston oil seal is damaged. Cylinders can be eliminated to replace oil seals.

(3) The power is not enough. It usually appears on old machines, or the motor is aging, or the pump is lost. It is relatively rare for the motor to age, because if it is an ageing problem, the hydraulic press is very loud because it cannot bring such a lot of power. You can insert the palm of your hand into the oil pipe to see, if the suction is strong when the machine is pressed, the pump will be fine, otherwise there will be problems.

4) The valve is blocked and the hydraulic valve is broken. The spring is stuck on the spring and cannot be reset, which will cause the pressure to not come up. If the valve is manually opened and closed, it must be cleaned.

(5) The pressure gauge of the hydraulic press is broken, which is also possible.
