1. The hydraulic oil is injected into the hydraulic motor. The injected hydraulic oil is measured by "flow", that is, the volume of hydraulic oil injected into the motor in one minute, and the unit is "L / min".
2. After the hydraulic oil is injected into the motor, it will flow out. Otherwise, all the hydraulic oil will gather in the motor, which will cause an explosion. Theoretically, the flow rate of hydraulic oil injected into the motor is equal to that from the hydraulic motor.
3. The flow rate is related to the speed of the motor output shaft, and they are proportional to each other. At this time, another invisible parameter of the motor is the displacement, that is, the volume of hydraulic oil injected or discharged when the motor rotates for one revolution. The unit is "ml / R".
4. The size of hydraulic motor is measured by displacement, so the size of motor refers to displacement.
5. The flow rate of hydraulic motor can be measured by flowmeter. Almost every hydraulic system will be equipped with a flowmeter to monitor the flow change of hydraulic system at any time.
