| The characteristics of the hydraulic motor |
| Hydraulic motor can be divided into two categories, high speed and low speed hydraulic motor, its features are: 1) hydraulic motor oil discharge port pressure slightly greater than the atmospheric pressure, oil outlet and inlet diameter of the same. 2) hydraulic motor often need to be positive and reverse, so should have symmetry in the internal structure. 3) when determining the bearing form of hydraulic motor, should guarantee in wide speed range can work normally. 4) hydraulic pump must make the pledge that we shall have self-priming ability in the structure, hydraulic motor at startup must ensure good sealing. 5) hydraulic motor generally need leaked oil. 6) in order to improve the hydraulic motor start and work performance, for torque ripple is small, small internal friction. |
