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, which 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.

It is needless to say that manufacturers with low standards bully the buyer and do not understand, all kinds of inferior components can blow up.
The 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-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 cluttered, 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.
