In addition to the hydraulic motor, the oil estuary, as well as a separate drain port; pump generally only into and out of the oil port (except axial piston pump), hydraulic motor, oil leakage and inlet therein connected. 4) The volumetric efficiency is lower than the hydraulic motor pump; usually relatively high operating speed of the hydraulic pump, hydraulic motor and lower output speed. In addition, the gear pump suction port large and small discharge port, and suction gear hydraulic motors, the discharge port of the same size; the number of teeth of the gear motor more than the number of teeth of the gear pump; vane pump shall be inclined installation, and vane motor The blade radial installation; vane motors rely root camel springs, hydraulic motor repair, it is pressed against the surface of the stator, the hydraulic motor parts, and vane pump is to rely on oil pressure and centrifugal force pressed roots on the stator surface mechanical loss of mechanical loss refers to the loss of torque on the pump. It is equal to pump large theoretical torque Tt and the actual input torque T ratio, set the torque loss of Tl, the mechanical efficiency of the hydraulic pump (2) hydraulic pump power 1) input power input power means acting hydraulic mechanical power on the pump shaft, when the input torque Ti, angular velocity ω = Tiω2) output power P means differential pressure Δp output power and output flow pump during operation of the actual suction pressure of the oil port between q product, namely P = Δpq (3) the overall efficiency of the overall efficiency of the hydraulic pump hydraulic pump is the actual output to its input power of the hydraulic motor _ _ crystal create a hydraulic factory direct hydraulic motor repaired by Jinan Jing Chong Hydraulic Machinery Limited. _ Crystal Chong hydraulic motor hydraulic hydraulic motor repair factory direct _ Jinan Jing Chong Hydraulic Machinery Co., Ltd.
