The requirements of the paper making and printing industries for vacuum systems combine "continuity" and "stability". Paper machine wire section dewatering and vacuum web transfer require long-term uninterrupted operation, while printing press feeders and folding and binding have higher requirements for pumping response speed. Traditional oil-lubricated vacuum pumps have the maintenance burden of oil mist emissions and regular oil changes. Leynow vacuum pumps are optimized for paper making and printing working conditions, and with stable vacuum output and convenient maintenance, have become a reliable choice for paper machine vacuum systems and printing equipment matching.
Challenges Faced by the Industry
The requirements of paper making and printing production for vacuum systems are not just about "pulling a vacuum", but more importantly, continuity, stability, and low maintenance. In practical applications, customers often encounter the following types of problems:
Long-term Continuous Operation
Paper machines and printing presses often require 24-hour continuous operation. Vacuum pump overheating or vacuum fluctuations will directly affect paper web quality and printing efficiency.
Intrusion of Paper Lint and Dust
Paper making and printing workshops contain paper lint, paper dust, and dust, which easily enter the pump body and affect the lifespan and operating stability of the vacuum pump.
Vacuum Degree Fluctuations Affect Quality
Processes such as wire section dewatering, feeder paper suction, and folding adsorption have high requirements for vacuum stability. Fluctuations will cause paper breakage, inaccurate registration, or adsorption failure.
High Maintenance Costs
Oil-lubricated vacuum pumps require regular oil changes and filter cleaning. Downtime for maintenance and consumable costs add up, affecting overall equipment utilization.
Leynow Paper Making and Printing Industry Solutions
Targeting the actual working conditions of the paper making and printing industries, Leynow provides overall vacuum solutions centered on vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Vacuum Acquisition Method Suitable for Paper Machines and Printing Presses
According to the vacuum degree and pumping volume requirements of paper machine dewatering, web transfer, or printing feeders, provide various configurations such as oil-free vacuum pumps, rotary vane vacuum pumps, and vacuum units, meeting the vacuum acquisition needs of different working conditions.
Selection Solutions Matched to Working Conditions
Based on the vacuum degree range, pumping volume, continuous operation duration, and workshop environment, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For the working conditions of 24-hour continuous operation of paper machines and high-speed operation of printing presses, the heat dissipation and intake filtration structures are optimized to reduce the risks of pump body overheating and paper dust intrusion, maintaining stable vacuum degree output.
