(1) The main basis for selecting the hydraulic motor of the line is the requirements of the host on the hydraulic device, such as rotation, speed ratio, work pressure, displacement, shape and connection size, volume efficiency, total efficiency and its quality, price, first -hand supply supply The convenience of use and maintenance.
(2) There are more types of hydraulic motors. The characteristics are different. For detailed uses and their working conditions, refer to the appropriate oil motor in the table below. The low -speed operation work can be selected at a low speed than the motor, and a high -speed motor deceleration device can be used. The five -star oil Mada in the tank is on the choice of these two solutions. Choose according to the structure and space conditions, equipment costs, and whether the driver rotation is reasonable.
(3) After confirming the type of hydraulic motor adopted, you can also select several specifications that can meet the requirements according to the need speed ratio and rotation. The characteristic curve of various specifications finds relative pressure drops, flow and high efficiency; the technical cost and efficiency analysis of hydraulic motors of the excavator to determine the detailed specification model, if the initial cost fee is important.
