The fluid coupling is a power hydraulic transmission device that uses the kinetic energy of the liquid to transmit torque.Since there is no fixed mechanical connection between the main and driven shafts, the torque is transmitted through the working fluid, which allows slip between the two shafts, can isolate the torque vibration and impact between the prime mover and the load, and can also make The prime mover starts without load, thereby protecting the power system from overload damage.Because of its many valuable features, fluid couplings are widely used in metallurgy, mining, electric power, lifting and transportation, engineering and construction, shipbuilding, petroleum, chemical, light industry and building materials industries.
According to the function, the hydraulic coupling can be divided into basic form and derivative form. The basic form is divided into three types: ordinary type, moment limit type and adjustment type. The derivative form is divided into hydraulic coupling transmission device and hydraulic reducer. , According to the structural characteristics, it can be divided into single cavity, double cavity and multi cavity. According to the position of the blade of the working wheel, it can be divided into straight slice and oblique slice.
