If the plunger pump is stuck during the use of the four-column Hydraulic Press, use the following methods to solve it.
The main cause of the jam of the plunger pump of the four-column hydraulic press is the abnormal cylinder bore deformation. Usually, when the hydraulic pump is assembled, the center steel ball falls off. As soon as the pump is started, the end face of the cylinder block is locked and the cylinder bore is deformed to kill the plunger; in addition, the center spring breaks and the cylinder support roller bearing cage is damaged. , It will also jam the rotating parts in the pump and make the plunger bite or destroy the hydraulic pump.
In this case, first check whether the parts of the hydraulic press are damaged. If there is damage, the parts need to be repaired, and if they cannot be repaired, they need to be replaced. If the cylinder body is not deformed so severely, we can press the film to keep it within the allowable error range of the shape and position, and then replace the cylinder with a suitable plunger corresponding to the outer diameter of the cylinder. In this way, the effect of using and replacing new parts Basically the same.
At the same time, check whether the plunger can be used. If it can be used, it will be repaired to make it meet the process standard. This can save a part of the cost and save the consumption of replacing new parts.
