Briefly introduce: What are the characteristics of magnetic levitation blower used in paper industry?

The magnetic suspension blower is applied to the papermaking industry, and its core feature is to meet the requirements of high humidity, dust and continuous operation of papermaking process. At the same time, it has the advantages of energy saving, oil-free cleanliness, low noise and easy maintenance, which perfectly meets the technological requirements of key links such as pulp treatment and wastewater treatment. The specific features are as follows:

Oil-free lubrication ensures the cleanliness of paper products.

The magnetic suspension blower relies on magnetic suspension bearings to support the rotor, and there is no mechanical contact and no need for lubricating oil during operation, so as to prevent oil stains from mixing into pulp or production water and prevent oil stains and impurities from appearing on paper. This feature is especially suitable for the production of paper products with high hygienic standards, such as food packaging paper and household paper.

Wide range frequency conversion speed regulation, accurately matching the demand of process air volume.

In papermaking process, the air demand of pulp aeration, black liquor treatment and waste paper deinking will change dynamically with raw material ratio and production load. The air volume adjustment range of magnetic suspension blower can reach 30%~100%, and the frequency conversion system can respond to the change of process parameters in real time, avoiding the energy waste of traditional Roots blower "big horse-drawn car", and saving energy by 30%~50% compared with traditional blower.

Resist harsh working conditions and adapt to the high humidity and dusty environment of paper mill.

The paper-making workshop is characterized by high humidity and much paper dust. The core components of the magnetic suspension blower (magnetic bearing and motor) are sealed, dust-proof and moisture-proof, and the impeller can be made of anti-corrosion coating material, which can tolerate the wet water vapor in the pulp aeration tank and the fiber dust in the deinking process of waste paper. The long-term operation failure rate is low, which meets the needs of 24-hour continuous production in paper mills.

Low noise and vibration, simplifying the factory layout.

The operating noise of magnetic suspension blower is ≤80dB, and the vibration amplitude is extremely small. It is not necessary to build a sound insulation room and a vibration reduction foundation separately, and it can be directly installed in the workshop, saving the capital construction space of the factory. This is especially important for paper mills with dense equipment layout, which can reduce the influence of noise on operators and improve the working environment of workshops.

Low maintenance cost, reducing the pressure of production operation and maintenance.

No mechanical wear parts, no need to change wearing parts such as lubricating oil and bearings regularly, only need to clean the filter regularly, and the maintenance period can be extended to 1-2 years, greatly reducing the labor maintenance cost and downtime. Compared with the frequent parts replacement and maintenance of traditional roots blower, it can effectively improve the continuous operation rate of paper production line.

Adapt to a variety of paper-making core processes

In addition to pulp aeration and black liquor treatment, it can also be used for scenes such as aerobic pool aeration in papermaking wastewater treatment and hot air transportation in paper drying. One equipment can flexibly match the requirements of multiple processes and improve the equipment utilization rate.
