Application of the New Vacuum Roll Internal Cleaning System
The stability and cleanliness of vacuum rolls on paper machines directly affect the operating efficiency of the paper machine. The dewatering performance and cleaning condition of vacuum rolls have a direct impact on paper sheet quality and roll maintenance cycle. For many paper machines, the holes of vacuum rolls get severely clogged after 3 to 4 months of operation.
To ensure normal operation of the paper machine and paper sheet quality, vacuum rolls have to be removed from the paper machine for manual cleaning by workers. This manual cleaning method consumes substantial manpower, resulting in high labor costs. It also greatly increases workers’ labor intensity, requiring them to work in tedious and harsh working conditions.
More importantly, frequent manual cleaning severely disrupts production schedules and reduces operational efficiency. Therefore, it is particularly urgent and critical to cut labor costs, reduce labor intensity and improve the overall efficiency of papermaking.
The FM New Vacuum Roll Internal Cleaning System effectively solves the above problems. It drastically reduces manpower input and labor costs. Meanwhile, it completely liberates workers from heavy and arduous manual cleaning work, effectively lowering labor intensity, greatly saving time costs, ensuring production continuity and improving operational efficiency.
Product Features
1.Outstanding Cleaning Performance The system penetrates deep into the vacuum roll to efficiently dredge and clean severely clogged holes, thoroughly removing contaminants to keep the vacuum roll in an optimal clean condition. It significantly improves the dewatering performance and cleanliness of vacuum rolls.
2.Scientific Cleaning Method It adopts a cleaning mode combining linear movement and rotation. While the trolley travels forward at a preset speed, the nozzles rotate simultaneously, realizing full-coverage, dead-angle-free cleaning for internal holes of the roll.
3.High Level of Automation Once started, the system runs automatically according to pre-set programs with minimal manual intervention. It reduces manual operational errors and guarantees stable and consistent cleaning results.
4.Simple Operation Procedures After the roll shell is disassembled from the off-mandrel roll body and placed at the designated position, the cleaning trolley can adjust automatically based on the inner diameter of the roll shell. Connect the high-pressure water hose after putting the trolley inside the roll shell. Press the start button, and the trolley will move forward at the preset speed while rotating nozzles synchronously for cleaning. No complicated operations are required.
5.Reduced Labor Intensity It eliminates the traditional requirement for off-machine manual cleaning every 3–4 months. Workers are freed from heavy manual cleaning work, and labor costs are saved.
6.Extended Service Life of Equipment Timely and effective cleaning keeps vacuum rolls in good operating condition and reduces roll wear caused by clogging and contaminant accumulation. This extends both the maintenance interval and service life of vacuum rolls.
