The rotary lobe pump is used in the paper industry

The rotary lobe pump greatly reduces manpower and improves production efficiency for papermaking enterprises. It is convenient and fast, reduces costs, and is easy to maintain. It is highly recognized and widely used in service enterprises. Familiar with the production process and working conditions of paper-making enterprises, Seiken Pumps has continuously developed and innovated in technology, providing product and technical support for various material transportation requirements, and has widely solved the problems of high viscosity, strong corrosiveness and abrasiveness, solid High volume fluid medium. And widely used in polyacrylamide-polyacrylamide (PAM), starch sizing agent, liquid rosin, rosin size, paper pulp, dry strength agent, wet strength agent, sizing agent, retention aid, defoamer, water treatment Chemicals, latex, coatings, etc.

1. The rotary lobe pump has different functions in papermaking due to the different uses of the materials. It is suitable for the auxiliary agent added by the wet strength agent to increase the wet strength of the paper sheet (fluid media such as urea-formaldehyde resin and phenolic resin). Retention aid is added to reduce the loss of fillers and fine fibers in the papermaking process (polyacrylamine, polyethylene oxide and polyethyleneimine and other materials), and the purpose of defoaming agent is to eliminate foam in the papermaking process ( raw materials such as silicone oil, turpentine, tridecanol, tributyl phosphate, amyl alcohol and octanol). Water repellent is mainly used in paper with high water resistance (paraffin wax, metal soap, glyoxal, melamine formaldehyde resin and dimethylaminoethyl acrylate, etc.).
2. Application of rotary lobe pump in paint preparation system Common medium china clay, CaCO3, TiO2, talc, starch solution, sizing agent, wax agent, casein, protein, formalin, alum, synthetic glue, wet strength agents, defoamers, and bleaching agents.
3. Starch cooking conditions are high temperature and high viscosity conditions for starch cooking and sizing and feeding.
4. Due to the characteristics of various mixed chemical coating materials, it is particularly important to select the overcurrent parts of the pump and the selection of mechanical seals. It is necessary to be familiar with the characteristics of chemicals, auxiliaries, rosin, dry strength agents, warm strength agents, sizing agents, retention and drainage aids, and defoaming agents, select the best formulation scheme, and the pH value of various chemicals And the viscosity is different, the addition metering is different, and the complexity of the working conditions is also different. Comprehensive selection and matching is required, and Hollysys has provided solid technical solutions for this and has been highly recognized by enterprise operators.
5. The cam rubber rotor pump helps papermaking enterprises to solve the treatment of production sewage sludge, and it is also the country’s most emphasis on environmental protection. Everyone is responsible. Papermaking wastewater contains hard impurities such as sand, cinder, pulp fibers, etc., which will cause great wear and tear to conventional pumps. Seiken pump owners recommend users to use rubber rotor pumps to help target sewage sludge conditions and establish a good production environment. And the use is stable, the pump cavity is equipped with a lining plate to increase the wear resistance of the overcurrent parts, and the mechanical seals of different materials are used to reduce the maintenance cost of wearing parts.
