Hydraulic coupling is a hydraulic transmission device, also known as hydraulic coupling. The structure of the hydraulic coupling is substantially composed of three corridors the shell, the pump wheel, and the turbine. The input shaft of the hydraulic coupler is connected with the motor and rotates with the gyration of the motor, which is the active part of the hydraulic coupler. The turbine and the affair shaft are connected together, which is the driven part of the hydraulic coupling and is connected with the cargo.
When the motor is running, the covering of the hydraulic coupling and the pump wheel is driven to rotate together, and the hydraulic canvas in the pump wheel blades rotates together with the drive of the pump wheel. Under the action of centrifugal force, the hydraulic canvas is thrown out of the pump wheel blades. At the external edge, it rushes to the turbine blade at the external edge, so that the turbine rotates under the impact force of the hydraulic canvas; the hydraulic canvas rushing to the turbine blade flows along the turbine blade to the inner edge, returns to the inner edge of the pump wheel, and is also pushed by the pump wheel again. Toss to the external edge again. In this way, the hydraulic canvas flows from the pump wheel to the turbine, and from the turbine back to the pump wheel to form a circulating liquid inflow. When the circulating hydraulic canvas in the hydraulic coupler flows from the inner edge of the impeller blade to the external edge, the pump impeller does work on it, and its speed and kinetic energy gradationally increase; During the process, the hydraulic canvas workshop on the turbine, and its speed and kinetic energy gradationally drop. The rotation of hydraulic canvas is caused by the speed difference between the pump impeller and the turbine, which causes a pressure difference at the external edges of the blades of the two buses. When the hydraulic coupler is working, the kinetic energy of the motor is transmitted to the hydraulic canvas through the pump wheel, and the hydraulic canvas transmits the kinetic energy to the turbine affair in the process of circulating inflow. During the process of circulating hydraulic canvas, it isn't subordinated to any fresh external force except the force between the pump impeller and the turbine. According to the principle of equal action force and response force, the necklace acting on the turbine by the hydraulic canvas should be equal to the necklace acting on the hydraulic canvas by the pump impeller, which is the working principle of the hydraulic coupling.
