Maintenance of the hydraulic motor is a hydraulic actuator motor system, the liquid pressure will pump energy into mechanical energy provided by its output shaft (torque and speed). High-speed motor gear motor with a small size, light weight, simple structure, technology is good, is not sensitive to the oil pollution, impact resistance and inertia is small. Disadvantages greater torque ripple, low efficiency, starting torque is small (only 60% of the rated torque of --70%) and poor low-speed stability. Today, the development of the machinery industry is getting ahead, while the hydraulic industry also will be vacated born. Hydraulic system pump motor power units, whose role is the original motivation of the mechanical energy into fluid pressure energy motor service, means the hydraulic system of pumps, which provides power to the entire hydraulic system. The general structure hydraulic gear pumps, vane pumps and piston pumps. By Cipian introduction, makes you a better understanding of the hydraulic pump.
