The important criterion for the quality of the precision four-column hydraulic cutting machine is the quality of its hydraulic system, the quality of the hydraulic system of the hydraulic cutting machine. What components are determined by it?
First, hydraulic pump
The hydraulic pump is the heart of the hydraulic system, and the hydraulic fluid needs to be pumped into the system. The standard 40-ton model should adopt 41 large-displacement hydraulic pumps to ensure high-pressure stable output of hydraulic oil. The standard manufacturer adopts 36 second-speed pumps and even lower, and the pressure is difficult to ensure stability.
Second, hydraulic valve
The domestic hydraulic component brand has risen rapidly in recent years, but there is still a big gap between imported and imported brands in terms of quality and reliability.
Because of the long-term ultra-high pressure and frequent use of hydraulic cutting machine systems, the current high-standard hydraulic cutting machine enterprises still use imported hydraulic components.
The low-standard manufacturers don’t have to say it, the bully buyer doesn’t understand, and all kinds of inferior components can be blown up.
3.Design of hydraulic system
When the hydraulic machine is working, the hydraulic oil passes through the fuel tank-oil pump-oil pipe-hydraulic valve-cylinder-finally back to the fuel tank. This whole process completes the blanking operation and needs A hydraulic circuit that is as efficient, smooth and leak-free as possible. If the design of the hydraulic circuit is unreasonable, the various adapters are disordered. Under the long-term action of the hydraulic oil air separation pressure and the saturated vapor pressure, the inner wall of the oil pipe will have the wear of the pits, and the wear of the oil pipe will cause a vicious cycle, so the machine sounds more and more. Large, the pressure is getting smaller and smaller, and various leaks will follow.
