Distinguish The Advantages And Disadvantages Of The Four-column Cutting Machine

- Jan 22, 2021-

A mechanical advantages and disadvantages of its determinants is very much, after all, not a mechanical can be said to be perfect, four-post hydraulic cutting machine, four-post hydraulic cutting machine in the hydraulic system is the whole machine absolutely new stations, so the hydraulic system decides the advantages and disadvantages of a four-column cutting machine, so specific needs judged from what parts? Here is a detailed understanding of it.

First point: hydraulic pump

The hydraulic pump is the heart of the hydraulic system. The hydraulic oil needs to flow into the system through the pump pressure. Standard 40 ton model should use 41 large displacement hydraulic pump, to ensure the stable high pressure of hydraulic oil output low standard manufacturers use 36 second grade pump or even lower, pressure is difficult to ensure stability.

Second point: hydraulic valve

Domestic hydraulic components brand in recent years to rise quickly, but no matter from the quality or reliability and the import brand is still a large gap.

Because the hydraulic cutting machine system for a long time and the use of frequent high standards of hydraulic cutting machine enterprises are still mainly used imported hydraulic components.

The third point: hydraulic system design

When the hydraulic system in the cutting machine works, the hydraulic oil passes through the oil tank - oil pump - oil pipe - hydraulic valve - oil cylinder - and finally returns to the oil tank. This whole process completes the blanking operation, which requires a hydraulic circuit as efficient, smooth and leak-free as possible.

If the hydraulic circuit design is not reasonable, a variety of joints, in the hydraulic oil and air separation pressure and saturated steam pressure under the long-term action of the inner wall of the tubing will produce potholes wear, and the tubing wear and cause a vicious cycle, so the machine voice is more and more, the pressure is less and less, a variety of leakage will also appear.
