The screen changer, as a core component in industrial production, its stable operation is crucial for the continuity of the production line. However, due to long-term use and wear, aging of screen changers has become a common problem, especially for skateboard screen changers. This type of screen changer activates the seal through manual adjustment or pressure, but in actual operation, it is often affected by various factors, such as wear caused by skateboarding, degradation of the sealing pressure ring, and damage to the filter screen.

Regular maintenance is essential to maintain the good operation of the screen changer. The maintenance cycle can range from once a week to once a year, depending on the usage and working environment of the screen changer. During the maintenance process, it is necessary to disassemble and assemble the screen changer, which is not only time-consuming but also costly. Therefore, it is crucial to keep the skateboard clean before maintenance to prevent polymer leakage into circuits and other equipment, causing greater damage.
To reduce the leakage problem of the screen changer, increasing the head pressure is an effective method. Although intuitively we may think that reducing pressure can reduce leakage, in reality, since seals respond to squeezing pressure, they can only work best at higher pressures. At lower pressures, the seal may loosen slightly, making low viscosity materials prone to leakage.
To address this issue, some screen changer manufacturers have launched updated versions of sliding plate sealing designs. These designs adopt a full steel segmented compression ring structure, aiming to solve leakage problems and promise lifelong leak free performance at any temperature and low viscosity. This design performs particularly well in high-temperature coating applications, ensuring the stability and reliability of sealing operations.
