Four Column hydraulic Press Why does the hydraulic cylinder expand?

First of all, this has something to do with the Four Column hydraulic press hydraulic cylinder itself. The slender cylinder barrel of the hydraulic cylinder is most likely to expand. Since the strength and stiffness are distributed in a parabolic state, the expansion occurs most often in the Four Column hydraulic press. Near the middle point of the working pressure chamber, it is proportional to the distribution pressure of the working oil. The editor recommends that hydraulic press manufacturers pay attention to calibrating the strength and stiffness of the hydraulic cylinder when designing the hydraulic cylinder; secondly, the material and structure of the Four Column hydraulic Press hydraulic cylinder Whether the design is reasonable or not depends on the material. If the material is of inferior quality or has low strength, it is conceivable that the safety performance cannot be guaranteed. Once the Four Column hydraulic Press is used for a long time, the hydraulic cylinder bore will expand, and the cylinder bore will expand. Failure to install a reinforcing hoop in the upper middle will also reduce the hydraulic cylinder's ability to withstand load.
Correct operation of the Four Column hydraulic Press is a safety prerequisite. At high speed or with a large load, the piston of the hydraulic press has a relatively large inertia and stops working instantly. The pressure in the chamber will increase sharply and exceed the maximum working pressure, causing the hydraulic cylinder to expand; and if you do not press The Four Column Hydraulic Press is operated according to the regulations and is often under load. If the buffer device of the hydraulic cylinder fails and is in an open state, the piston cannot decelerate and hits the cylinder head, causing overpressure. These are very dangerous situations and everyone must pay more attention.
