The emergence of the hydraulic system is destined to shine, hydraulic technology appeared in the 18th century, then rapid development, a variety of fields have appeared on the hydraulic technology and mechanical products, such as hydraulic cutting machine.
The birth of hydraulic cutting machine is to a great extent improve the efficiency of the cutting machine products, hydraulic system is very powerful, today's hydraulic systems are relatively closed, but nothing is absolute, hydraulic cutting machine hydraulic system may also be because of the problem and a failure, it today to see together about how the hydraulic system of hydraulic cutting machine system for maintenance and maintenance.
First of all, compared with other parts, the hydraulic system of hydraulic cutting machine is relatively fragile, especially in the anti-pollution ability is still relatively obvious disadvantages, the following to understand the specific disadvantages of hydraulic cutting machine in this area are mainly shown in it.
Pollutants mixed with the hydraulic system of hydraulic cutting machine will accelerate the wear and burn of hydraulic components, appreciation damage, or cause valve failure, or cause noise;
Pollutants will block the throttling hole or throttling gap of hydraulic components, change the working performance of the hydraulic system, cause maladjustment or even complete failure, resulting in misoperation and accidents;
Dust particles in the hydraulic cylinder will accelerate the damage of seals, cylinder inner surface of the strain, so that leakage increased, insufficient thrust or unstable action, crawling, speed down.
