How to distinguish the advantages disadvantages of precision four column hydraulic cutting machine?

One 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. The standard 40 ton model should adopt 41 large displacement hydraulic pump to ensure high pressure stable output of hydraulic oil. The 36 second gear pump even lower is adopted by low standard manufacturers, so it is difficult to ensure stable pressure.

Two points: hydraulic valve

In recent years, the domestic brand of hydraulic components has increased rapidly, but there is still a big gap between domestic imported brands in terms of quality reliability.

Due to the long-term high pressure frequent use of hydraulic cutting machine system, the high standard hydraulic cutting machine enterprises still adopt imported hydraulic components.

Low standard manufacturers do have to say, bully the buyer does understand, all kinds of inferior components can be blown up.

Three points: hydraulic system design

When the hydraulic system in the cutting machine works, the hydraulic oil goes through the oil tank, oil pump, oil pipe, hydraulic valve, oil cylinder then returns to the oil tank. This whole process completes the blanking operation, needs a hydraulic circuit as smooth as possible without leakage.

If the hydraulic circuit design is reasonable, all kinds of connectors are disordered. Under the long-term effect of hydraulic oil air separation pressure saturated steam pressure, the inner wall of oil pipe will have pitted wear, the wear of oil pipe will cause vicious circulation, so the noise of the machine is increasing, the pressure is becoming smaller smaller, all kinds of leakage will appear.
