Network optimization information:

Its main features: high speed, small moment of inertia, convenient starting and braking, high speed regulation and reversing sensitivity High speed hydraulic motor The output torque is not large.

Main parameters of hydraulic motor

nervous.

Conversion unit: 1Mpa=10bar=1 × 10N/m2=1N/mm2 Working pressure: input the actual pressure of motor oil.

Pressure difference under working condition: the difference between the inlet pressure and the outlet pressure of the motor.

Nominal pressure: the pressure at which the engine can continue to operate normally according to the test standard.

Volume and flow.

Volume: Hydraulic motor Without considering leakage, Low speed hydraulic motor A certain volume of liquid needs to be input every revolution.

Unit conversion: 1ml/r=1cm/r=1 × 10mm/r=1 × 103/r=1 × 106m3/r Flow: Hydraulic motor of sweeping car The hydraulic motor is required to input the volume of liquid in unit time.

In case of no leakage calculation, the leakage flow is regarded as the actual flow.

Flow unit: ml/min=1 × 103L/min.

Volumetric efficiency

Volume efficiency nMv: the ratio of actual input quantity to theoretical input quantity.

Mechanical efficiency

Mechanical efficiency: equivalent to the ratio of the actual output torque of the motor to the theoretical output torque.

Speed.

Speed: number of revolutions of hydraulic motor in unit time (r/min)
