Four-column hydraulic press action slow solution

In a lot of four-column hydraulic press manufacturers do not know why this machine suddenly slow action is caused by what reasons, then four-column hydraulic opportunity because of what causes its slow action, its solution is what? So let's explain the reasons for it and how to solve it.

The first point is that when the piston movement speed of the four-column hydraulic press is very high, the steel ball of the check valve will move, which will cause the action of the hydraulic cylinder to appear irregular. When we encounter this problem, we need to convert the steel ball to a pop-valve load spool with a guide valve.

The second point is when the hydraulic cylinder in the four-column hydraulic press appears air, at this time you will also find that the four-column hydraulic press has a slow action phenomenon, you can use the exhaust equipment to exhaust, check whether the piston rod reciprocating part of the seal ring is inhaled air. If so, the seal may be faulty and should be replaced.

The third point is that when the hydraulic cylinder of the four-column hydraulic press is not sensitive, when the rubber hose is peeled off inside, it will cause intermittent defects in the oil circuit, which constitutes irregular hydraulic cylinder action. Cleaning method: Timely conversion of rubber hose.

Fourth, check whether the hydraulic pump is operating normally. If the hydraulic pump is not operating properly, the rotation of the pump is blocked or slightly dead, clarify the problem in the hydraulic pump, repair or replace the hydraulic pump.

Fifth 1. Check the running status of the piston. When the hydraulic cylinder of a four-column hydraulic press with a buffer device starts in reverse, the piston often stops temporarily or moves backward. This is because the orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum is present. The problem should be that the orifice of the check valve is enlarged.
