  • Roots blower belongs to volume rotary blower. The air cavity formed between the rotor and the shell, the air in the intake chamber is formed by the two blades to seal the cavity to the exhaust cavity, so as to realize the transportation and pressurization of the gas. The roots blower made by Kingturbo has many advantages, like high efficiency, better working stability and lower noise. It can be widely used for evaporation crystallization industry and other application.

    Roots blower technical advantages:

    • Casting with resin sand casting process, casting quality is fully guaranteed.
    • In strict accordance with the theory of involute impeller design and computer simulation, to do many times balance test before installation. Fully guarantee the meshing characteristic of involute, effectively reduce leakage, improve efficiency.
    • Shell, wallboard processed by high-precision digital display CNC machine, high precision, stable quality.
    • The inlet and outlet adopt spiral structure and install muffler, which makes the intake and exhaust pulsation gentle, the vibration is small, and the noise is low.
    • The lubrication of the main and auxiliary fuel tank splash lubrication, not only make more reliable, and has solved many shortcomings of grease lubrication, effectively improve the service life of the bearing.
    • The sealing structure is reasonable, oil and gas cannot enter the casing. Therefore, the output air is clean, without grease.
    • Bearings is Japanese brand; V-Belt is US brand;
    • Fan gear adopt 20CrMnTi carburizing treatment, grinding processing, tooth surface is more wear-resistant, can significantly reduce gear noise.
    • 48 hours of trial operation before delivery, to guarantee on the quality at jobsite

    Remark:

    1. The mass flow in the table is only for reference. The specific model should be confirmed per actual evaporation temperature;
    2. The maximum mass flow is calculated based on inlet temperature 100degree C, The specific model should be confirmed according to the actual condition;
    3. The table only list to max 4.5ton/h, for larger capacity requirement, we recommend centrifugal compressor for better performance and more economic choice;
