I feel like he's a little unclear, it should be"How to measure"It's pretty much the same.

The volumetric efficiency of the motor will change with the change of system pressure, the higher the pressure, the lower the volumetric efficiency. According to the torque and displacement of the motor, the working pressure of the motor can be calculated, which should be 10mpa according to the hydraulic manualThen use the flow rate of the motor 80*1100 1000=88L min

If the working pressure is calculated to be 10MPa, then the volumetric efficiency is 88 94 =

Summary. Hello! Your question has been seen and the answer is being collated. Please wait a moment.

Hello! Your question has been seen and the answer is being collated. Please wait a moment.

Is it a university topic? Yes.

For hydraulic drivetrains, the following description is incorrect ().

a.Hydraulic installation and pin leasing is not easy to achieve overload protection, so the service life is short (correct answer) bSince the depressurizing element lubricates itself, it has a long service life.

c.Hydraulic system failures are easy to check and troubleshoot (correct answer) dThe hydraulic system is not easy to check and troubleshoot.

The power element of the hydraulic transmission is the key to the common sun.

a.Oil pump. b.Oil motors.

c.Cylinders. Correct answer to the case of the Divine Chain: a

1: Power element, control element, actuator, auxiliary element.

2. Dynamic viscosity, kinematic viscosity, relative viscosity.

3. Local pressure loss ,。。

4: Quantitative pump, variable pump.

5. Pressure energy, mechanical energy.

6. Flow control valve, pressure control valve, direction control valve.

7. There are many kinds, such as O-type function, H-type function, P-type function, Y-type function, etc.

8 motors, hydraulic cylinders.

10. One-way variable pump.

Two. 1. The check valve only allows the oil to flow in one direction, and the hydraulic check valve can make the oil flow in both directions by controlling the pressure of the control port.

The others can't give accurate answers for the time being, and you have to check the textbook, I hope these can help you.

Upstairs are all correct, add one.

2. 2. The closed volume and closed volume are transformed, and the suction oil cavity is separated.

1: Power unit, auxiliary device, actuator, working medium, control and adjustment device.

2. Dynamic viscosity, kinematic viscosity, relative viscosity.

3. Pressure loss along the way, local pressure loss.

4: Quantitative pump, variable pump.

5. Pressure energy, mechanical energy.

6-way control valve, pressure control valve, flow control valve.

7O, H, P, Y, K, M, X function codes.

8. Hydraulic cylinder, hydraulic motor.

9 (1) The pressure of the liquid acts on the bearing surface along the direction of the inner normal.

2) The pressure at any point within a still liquid is equal in all directions.

10. One-way variable pump.

Two. 1. The ordinary check valve will be cut off when the liquid flows backwards, and the hydraulic check valve will be the same as the ordinary check valve when the control port does not enter the control pressure oil, and the liquid will not be cut off when the control oil is introduced.

2. Motor drive, working medium, sealing volume, oil pipeline.

Give me a share, thank you, I'm in a hurry.

1.Power Sources, Hydraulic Components, Hydraulic Accessories, Actuators.

###4.Constant Pump: Variable Pump.

5.Fluid pressure Linear motion.

6.Directional valves, pressure valves, flow control valves.

8.Hydraulic cylinders and hydraulic motors.

II.1Check valves include hydraulically controlled and non-hydraulically controlled, the reverse on-off of the hydraulically controlled check valve can be controlled by the external oil circuit, and the ordinary check valve cannot reverse the oil flow.

What is hydraulics and how does it work? Today is a long time to see.
