The service life of the screen pressing machine of the rewinder is long, and the sealing performance is certainly quite good. In addition, the sealing state is quite stable during long-term operation, and the leakage is quite small. According to preliminary data, it is about 1% less than the leakage of the soft packing seal. The mechanical seal face is composed of materials with good self-lubricating and wear resistance, and also has a wear compensation mechanism. Therefore, the wear of the seal face is relatively small under normal working conditions. Generally, it can be used continuously for 1-2 years, and specially for more than 5-10 years.
The screen pressing machine of the second-hand rewinder does not need to be adjusted during operation, because the mechanical seal is made to fit the friction pair by spring force and fluid pressure. Even if the friction pair is worn during operation, the seal end face will always automatically keep fit. Therefore, after correct installation, users do not need to adjust frequently. It is convenient to use and suitable for continuous and automatic production.

The shaft or shaft sleeve surface of the screen pressing machine of the second-hand rewinder is not easy to wear, because there is almost no relative movement between its mechanical seal and the shaft or shaft sleeve, so the wear on the shaft or shaft sleeve is very small. The vibration resistance of the vacuum screen mounter is strong, and the mechanical seal has a buffering function, so when the equipment or shaft vibrates within a certain range, it can still maintain a good sealing performance!
