    Direct pulling type speed hydraulic coupling


    The self-developed hydraulic coupling has the features of high speed, high power, sensitive speed regulation and cost efficiency, and has received the national patent (The patent name: Direct pulling type speed regulation device of hydraulic coupling, and the patent number: ZL2008 2 0122800.0).


    ●Product Model and Performance Parameter

    Product Model

    Performance Parameter

    YOCQ-X Series

    P=4400kW-5500kW

    YOT Series

    P=3980kW-4365kW


    ●Advantages

    1. It has reasonable structure, advanced performance and high reliability, and can meet the requirements of long-term continuous operation conditions in metallurgy, building materials and power generation industries;

    2. The motor can be started at no load, and it is not necessary to select a prime mover such as a motor with a large power head capacity, and the fluctuation of the grid load can be reduced;

    3. Speed regulating fluid coupling has overload protection performance;

    4. Isolation of vibration to slow down the impact;

    5. No direct mechanical contact between transmission parts and long service life;

    6. High transmission efficiency at rated load;

    7. With hydraulic control speed control device and two half shafts, it is easy to realize long-distance automatic operation.


    ● Technology Feature

    It adopts the unitary herringbone design, and its pulse-on is steady without impact. It can complete non-grade speed-change (25% to 100%) to satisfy the sliding pressure motion produced by the water pump that adapts to the boiler.


    ●Scope of Application

    It is used for speed regulation motion of water feed pump unit and fan in generator unit and other high-power and high-speed centrifugal machinery, as well as the pulse-on motion of the boiler water feed pump unit of the 1000MW-capacity unit.
