Hydraulic system transmission technology of oil cutting machine developed rapidly after its birth in the 18th century. Today, hydraulic transmission equipment has been widely used in all walks of life, especially in modern large production lines, engineering machinery. Hydraulic transmission technology has its incomparable advantages. That is the main reason why it has grown so rapidly. At the same time, the hydraulic transmission equipment has its fragile side, including the low anti-pollution ability is a prominent weakness. To keep the hydraulic system running normally and reliably, the whole hydraulic system must be kept clean.
Pollutants mixed with the hydraulic system of the hydraulic automatic cutting machine will accelerate the wear, burn, appreciation damage of the hydraulic components, or cause valve action failure, or cause noise; The pollutant will block the throttle orifice or throttle gap of the hydraulic components, change the working performance of the hydraulic system, cause maladjustment or even complete failure of the action, resulting in misoperation and accidents; Dust particles in the hydraulic cylinder will accelerate the damage of the seal, the surface of the cylinder cylinder tension, so that the leakage increase, insufficient thrust or unstable movement, crawling, speed down. Abnormal sound and vibration can also cause filter screen blockage, hydraulic pump suction difficulty, return oil is not smooth and produce cavitation vibration and noise, when the blockage is serious, the filter screen will be broken because of the excessive resistance, the complete loss of filtering effect, resulting in a vicious cycle of the hydraulic system.
Hydraulic system pollution for many reasons, from the pollution mechanism, divided into two kinds: pollutants, lurking in the production installation process of chip, burr, sand coating, abrasive, welding slag, embroidery and solid particles such as dust, and their harm to the cutting machine hydraulic system is bigger, the stage must be to strengthen management and ensure the safe and reliable operation of the hydraulic system can after installation.
