can be divided into piston hydraulic motors, gear motors and pg电子下载-pg电子游戏 . more types of piston motors, axial piston and radial piston motor. most are high-speed axial piston motor, radial piston motors are mostly low-speed motor. the picture shows the axial piston motor schematic. pressure oil through the oil pan into the cylinder with the body, forcing the plunger out from the cylinder, and slide along the inclined plate, the cylinder together with the shaft rotation for power, oil pan with oil return through the other opening discharge. motors and gear motors are high-speed motor blades, their inertia and output torque is small, easy to start and reverse, but unstable at low speed or efficiency significantly. pump only one-way rotation, while the hydraulic motor is able to inversion, so the gear motor oil inlet symmetry, while the large gear pump export import small. vane motor the rotor blade radial arrangement; vane pump is not a radial arrangement of leaves, and a certain inclination.
because the hydraulic motor has the same basic structural elements - closed but you can cycle with the volume and the corresponding oil sector. however, due to the hydraulic motor and pump have different working conditions, performance requirements on them are not the same, so the same type between the hydraulic motor and pump, there are still many differences. the first hydraulic motor should be able to now, reverse, and therefore requires that its internal structure symmetry; hydraulic motor speed range required is large enough, especially for the minimum steady speed hydraulic motors have certain requirements. therefore, it is usually with rolling bearings or hydrostatic bearings; second hydraulic motor oil as the input conditions to work under pressure, and thus do not have the self-absorption capacity, but needs some initial tightness, can provide the necessary starting torque. because of these differences, making the hydraulic motor and hydraulic pump is quite similar in structure, but not reversible work.
according to their structure type hydraulic motor can be divided into sub-gear, vane, piston, and other types. by hydraulic motor rated speed is divided into two major categories of high-speed and low speed. the rated speed is higher than 500r/min speed hydraulic motor, the rated speed is lower than 500r/min speed hydraulic motors. welcome to purchase!
