Discussion Overview

The discussion centers around the functioning of hydraulic motors within hydraulic systems, particularly in the context of machinery used in engineering applications. Participants explore how hydraulic motors, pumps, and solenoid valves interact to facilitate mechanical movement.

Discussion Character

  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant describes hydraulic motors as functioning similarly to water wheels, where pressurized fluid pushes against vanes to turn a shaft, with fluid returning to the pump after use.
  • Another participant notes that the pump operates as a reversed version of the motor, emphasizing the role of a drive motor in supplying pressurized oil to the hydraulic motor.
  • A later reply mentions the specific application of the hydraulic motor in a spreader used with cranes, suggesting that the application context may influence the scale of the system.
  • One participant expresses uncertainty about the matching of the motor with a cylinder (referred to as a jack) in this specific instance.
  • Another participant provides a definition of the hydraulic motor, stating it converts hydraulic energy into mechanical rotational energy, and shares links to external resources for further understanding.

Areas of Agreement / Disagreement

Participants present multiple perspectives on the operation of hydraulic motors and their components, with some points of agreement on basic principles but no consensus on specific applications or configurations.

Contextual Notes

There are unresolved questions regarding the specific matching of hydraulic motors with cylinders and the implications of different applications on system design.

Hey Respected seniors,
I want to know that how the hydraulic motor works?
Im working as a trainee engineer in a company..
I watch daily a machine that have hydraulic motor, pump, solenoid valve...
All these things are for the movement of a shaft which is connected to a jack( I see, there are two cables/nozzles for pump pressures attached with that jack..). ..

PLZ simply tell me how the hydraulic motor, pump, solenoid valve work together?

thanx & best regards

Hydraulic motors are basically water wheels. A fluid under pressure pushes against vanes attached to a shaft and makes the shaft turn. After doing a little pushing the fluid is drained from the motor and returned to the pump that pressurized it. The pump itself is just a reversed version of the motor -- something turns a shaft that has vanes which pushes fluid out of a port under pressure.

There should be some good diagrams of these things on wiki or google someplace if you poke around a bit.

Beating the analogy a little further, this is pretty much how an electric motor or generator works as well...see the Hydraulic Analogy.

thanx a lot...
 
Actually the machine that I discussed is a SPREADER which is used with CRANES(ship to shore,sts, and rubber tyre gentry,RTG)..
So If anybody is working at PORT then I request him, please tell me in detail,thanx

The specific application is pretty much irrelevant, except perhaps as regards scale. The pump (vane or lobe type), under the influence of a drive motor, supplies pressurized oil to the motor (which is just a pump fed from the other end). The valve, whether electrical or mechanical, controls the flow of oil into the motor. I don't quite understand the particular matching of a motor with a cylinder (which you called a jack) in this instance.
 
how a hydraulic motor works

The hydraulic motor is the component of a Hydraulic System that convert hydraulic Energy from the hydraulic system into mechanical rotational Energy by rotating the shaft.

This is a good explanation of the subject.

Take a look at this video:

I hope this is what you are looking for.

Bye
