Analysis of external filtration structure of hydraulic device of hydraulic press

What is the external filtration structure of the hydraulic device of the hydraulic press? Let's break it down:

When the plunger of the hydraulic press is bitten, the more important parts of the hydraulic cylinder are removed and replaced. Moreover, the probability of correction of damaged parts is actually not large, so it is usually necessary to choose a replacement method to complete the removal.

After the pump of the hydraulic press runs for a period of time, the mating interval formed by the friction damage of the plunger is relatively large, so when the pressure is 4 columns, the pump of the hydraulic press cannot increase the pressure. Higher less.

Factors leading to the above situation: in addition to paying attention to the use of oil, the heat treatment hardness of the plunger is low, the raw material is not qualified, and the surface roughness of the cylinder. However, this phenomenon should be characterized by more uniform wear when it occurs. For plunger and cylinder wear, replacement methods are usually used.

This type of correction is as fast and efficient as possible, but at a higher cost. In fact, as long as the small hole deformation of the hydraulic cylinder of the hydraulic press is not large, it is usually possible to use fine or abrasive methods to make the shape and orientation accuracy meet the tolerance requirements. The outer diameter of the cylinder is then changed to enlarge the plunger, and the horizontal hydraulic press is the same as the new one.

The plunger of the hydraulic press damaged the outer surface of the cylinder. In fact, it can't be fixed. External plating, tinning or low temperature ferroelectric preparation processes can also complete the repair with the required hardness, collaborative standard and precision. And it also works for surface roughness.
