It plays an important role in controlling the flow rate and flow direction of hydraulic oil, and thus controlling the output pressure of the hydraulic oil. As the name implies, the hydraulic pump swing seat is a component inside the hydraulic pump that can generate a swinging motion. It is usually arranged in the hydraulic pump in cooperation with the swing, and controls the output pressure by changing the flow path and speed of the hydraulic oil; during the production process of the swing seat, rotary processing is required, so a rotary processing fixture will be used.
