  • Description

    Application of magnetic levitation vacuum pump

    Energy saving efficiency

    Direct drive three-dimensional flow impeller of high-speed permanent magnet motor without transmission loss.
    Compared with water ring vacuum pump, it can save more than 40% of energy.
    Compared with multi-stage centrifugal vacuum pump, it can save more than 20% of energy.
    Compared with single-stage high-speed vacuum pump, it can save more than 15% of energy.

    Stable and reliable

    Equipped with auxiliary bearings and power-off self-generating system to avoid equipment damage caused by accidental power-off.
    It has anti-end vibration function and anti-overload function.
    No friction, avoiding bearing wear and ensuring long service life of equipment.

    Intelligent

    PLC + GPRS/3G/4G is used to monitor the running state of vacuum pump in real time, and realize intelligent regulation and manual control of vacuum degree.
    It can be conveniently connected with the user's central control system, realize the standard IoT for joint control, and control the operation of the vacuum pump anytime and anywhere.

    Oil-free and water-free

    High-speed permanent magnet motor is directly connected with three-dimensional flow impeller, which needs no transmission structure or lubricating oil.
    Magnetic levitation bearings use magnetic levitation and have no mechanical contact with the high-speed rotating three-dimensional flow impeller, which converts kinetic energy into gas pressure potential energy and forms negative pressure vacuum without working fluid.

    Easy to installation and maintenance-free

    Integrated lifting, compact structure, convenient installation, and one-button start-stop.
    No mechanical maintenance is needed in daily operation, and only the filter plate needs to be cleaned.
