When should you change the screen exchanger?

When should you change the screen exchanger?


After the filter plate is produced for a period of time, the plastic melt enters the flow channel, and when a predetermined pressure difference is formed, the screen should be changed. The screen changing work uses the hydraulic system to push the ram to move accordingly, prompting the filter plate to exit the working position while another filter plate enters the working position, and then open the protective cover when it stops moving. Use tools to quickly clean the melt on the ram and around the filter mesh, remove the old filter and replace it with a new one to complete the work.This machine is equipped with a pressure sensor and a display in front of the screen to monitor the blockage of the filter screen to ensure timely screen replacement. The friction pair of the screen changer is made of high-hard and wear-resistant materials to ensure long-term use.
