Failures and Repair Measures of Pressure Screen
August 07, 2024
Pressure screens are a new type of recycled pulp screening equipment, which can be widely used in the coarse screening, fine screening and screening of pulp before paper machines for various waste paper pulps. Pressure screens are pulping equipment and belong to the category of equipment accessories. During the application of pressure screens, scaling occurs due to factors such as process water, calcium and magnesium hardness, pH value, conductivity, total alkalinity, temperature, etc., which can easily lead to failures. Therefore, repair measures need to be taken. Let us introduce them to you below.
What are the failures?
1. Increase the number of unplanned shutdowns, causing production interruptions, thereby affecting the production efficiency of the device. Shutdown for cleaning, increase maintenance costs and additional labor load;
2. Cause paper diseases and affect product quality;
3. Increase energy consumption losses;
4. Increase chemical consumption and pollution load;
5. Cause production accidents and reduce equipment life.
What are the repair measures?
Traditional repair measures include shutdown chemical cleaning, shutdown high-pressure water cleaning, adding antiscaling agents, manual mechanical cleaning, shutdown disassembly and replacement, etc., but they are time-consuming and labor-intensive, and the repair effect is not ideal. In response to the above problems, advanced foreign maintenance methods mostly use electronic descaling devices to solve them.
