continuous hydraulic screen changer with double piston type
two filter screens work in the same time, and the screen changed one after the other.no interrupt the production or melt fluid flow
performance
1,Double-piston screen changer works simultaneously. One net works. Another replaced; without interrupting the flow of material and production. And eventually fulfills the exchange of screen without stopping the machine.
2,Exhaust system device can fully defuse the gas mixed in the materials, then improving product quality. And double channels expand the filtration area to meet more productive, more high-quality production need s from customers.
How to work
How to work
To change the screen, the pistons are ejected from the housing one after the other using hydraulic cylinders. Once replaced, they are returned to their production position in the same way. During the brief screen change process, the melt flows continuously through the other piston, thereby ensuring the system's constant operation
