How To Distinguish Pros And Cons Of Four Column Hydraulic Die Cutting Machine?

- Dec 27, 2019-

There are many determinants of the quality of a machine. After all, no machine can be said to be perfect, so is the four-column hydraulic cutting machine. The hydraulic system in the four-column hydraulic cutting machine is definitely a new station for the entire machine. Therefore, the hydraulic system determines the pros and cons of a four-column Hydraulic Die Cutting Machine, so which components need to be judged specifically? Let's take a closer look at it.


First point: hydraulic pump


The hydraulic pump is the heart of the hydraulic system, and the hydraulic oil needs to flow into the system through the pump pressure. Standard 40-ton models should use 41 large displacement hydraulic pumps to ensure the high-pressure and stable output of hydraulic oil. Standard manufacturers use 36 second-speed pumps or even lower, and it is difficult to ensure stable pressure.


Second point: hydraulic valve


Domestic hydraulic component brands have risen rapidly in recent years, but there is still a big gap with imported brands in terms of quality and reliability.


Due to the long-term ultra-high pressure and frequent use of hydraulic cutting machine systems, high-standard hydraulic cutting machine enterprises still mainly use imported hydraulic components.


Third point: hydraulic system design


When the hydraulic system in the cutting machine is working, the hydraulic oil passes through the fuel tank-oil pump-oil pipe-hydraulic valve-cylinder-final return to the fuel tank. Hydraulic circuit.


If the hydraulic circuit design is unreasonable and various adapters are disorderly, the inner wall of the oil pipe will cause pothole wear under the long-term action of hydraulic oil air separation pressure and saturated steam pressure, and the wear of the oil pipe will cause a vicious cycle. The pressure is getting larger and smaller, and all kinds of leaks are coming along.
