What are the characteristics of the piston rod? The manufacturer of the hollow double piston cylinder will explain it to you.

Hollow double-piston cylinder manufacturers believe that when the hydraulic cylinder is working, the piston often extends out of the hydraulic cylinder. In industrial applications, external environmental dust is inevitable. When dust and other impurities stick to the piston rod, the dust seal will completely remove them. When the piston rod retracts into the hydraulic cylinder again, impurities such as dust attached to the piston rod will be mixed into the oil. Over time, more and more impurities are found in the oil. At this time, the oil mixed with impurities is equivalent to abrasive. When the system is working, continuous grinding of seals will cause damage to the seals of other parts in the hydraulic system and the seals of the hydraulic cylinder itself. As the grinding time increases, the seal wear becomes more and more serious, and leakage gradually occurs.

Hollow double-piston cylinder manufacturers believe that if the piston rod is too smooth, or the surface roughness of the piston rod is too low, the hydraulic oil lubricated by the sealed piston rod will be scraped off. Without the lubrication of lubricating oil, the friction coefficient between the piston rod and the sealing ring will become larger. At this time, friction will generate more heat and wear will increase, causing premature seal failure and leakage.

Many users should still pay more attention to quality when choosing piston rods. In fact, in many cases, the quality of a product will directly affect its service life. However, we can properly control the piston rod from the perspective of service life. Let’s learn about this knowledge together!

Hollow double-piston cylinder manufacturers believe that in actual use, the piston rod plays a very important role. If it is at high temperature, it can also effectively protect the hydraulic oil in the hydraulic cylinder, withstand large pulsations and pressure impacts, and effectively directly block pollutants. However, if the piston rod is not effectively maintained during use and the seal of the piston rod is damaged, the leakage of hydraulic oil will cause the company to lose human and financial resources.

The main sealing structure of the piston rod is a dust ring working together with a high-pressure sealing ring or a low-pressure combined sealing ring. Although the imported Y-shaped combination sealing ring is expensive, it basically does not leak. If the angle of the sealing lip is improperly designed, material flow on the lip may easily occur at high temperatures, changing the size and shape of the sealing lip, resulting in sealing performance failure.

Manufacturers of hollow double-piston cylinders believe that the main cause of piston rod seal failure is actually pollution, so the oil film on the surface of the piston rod needs to be resolved in time. However, there are pros and cons to this situation. Although the oil film will absorb dirt and directly adhere to the surface of the piston rod, the oil film also has its own effect, so we should all know that the sealing performance of the piston rod is very important!

The above are some knowledge points about piston rods, I hope they can help everyone.
