How to distinguish the advantages and disadvantages of four-post cutting machine?
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 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. 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 high-pressure and stable output of hydraulic oil. Standard manufacturers use 36 second-stage 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 the hydraulic cutting machine system, the current high-standard hydraulic cutting machine enterprises still mainly use imported hydraulic components.
The third point: hydraulic system design
When the hydraulic system in the cutting machine is working, the hydraulic oil passes through the oil tank-oil pump-oil pipe-hydraulic valve-cylinder-and finally returns to the fuel tank. This entire process completes the punching operation, which requires an efficient, smooth and leak-free 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. As the pressure increases, the pressure becomes smaller and smaller, and various leaks also occur.
