The plunger pump is an important device used to complete the suction of hydraulic oil in the forming hydraulic press. In the long-term operation process, the plunger pump is also more prone to failures. It is more common for the plunger pump to be stuck. So, what is it? Cause the plunger pump of the forming hydraulic press to jam?
Generally speaking, the main reason for the jam of the plunger pump of the hydraulic press is caused by abnormal cylinder bore deformation. Usually, when the hydraulic pump is assembled, the steel ball in the middle falls down. As soon as the pump is started, the end face of the cylinder block is jammed and the cylinder bore deforms and bites the plunger; the middle spring breaks and the cylinder supporting roller bearing stand is broken and destroyed. , It will also jam the modified parts in the pump and cause the plunger to seize or damage the hydraulic pump.
If the plunger pump of the forming hydraulic press is found to be stuck, first check whether the parts can be broken or destroyed. If there is a need to repair the parts, they need to be replaced and repaired in time. Assuming that the cylinder body is not deformed so severely, you can press the film to make it within the allowable error range of the shape and position, and then replace the cylindrical outer diameter to take care of the suitable plunger. How, the application is the same as the effect of new parts.
In addition, it is necessary to check whether the plunger of the forming hydraulic press can be used. If it is severely worn, it needs to be repaired to make it meet the process standards. This can save a part of the cost and save the consumption of replacing new parts.
