Although there might be some resemblance between hydraulic motor and hydraulic pump, they are meant for different uses hence cannot be substituted.
A hydraulic motor is aimed at converting hydro energy to mechanical one and creating circular movement. It functions by a rotor being turned by the force of fluid which is connected to a load-driving shaft.
In contrast, a hydraulic pump converts mechanical energy into fluid energy and creates flow. It moves hydraulic fluid from the reservoir into the hydraulics system through application of mechanical forces.
While it could be likely that a hydraulic motor would move fluids in reverse or generate some pressure, but this does not reduce its incapability as compared to any possibility of acting as a hydraulic pump. Hydraulic motors do not have needed internal components or design so as to produce high pressure flow that commonly flows in most industrial systems.
Furthermore, hydraulic engines have lower efficiencies compared to hydraulic pumps; hence they cannot deliver the same fluid flow as a hydraulic pump with the same input power. Some examples of these situations include serving as a low pressure pump or giving accessory hydraulic power where a motor can act as a substitute for the pumps. However, it is not common to encounter such instances and one must be cautious on what the hydraulic system requires and supports.
Hence, it is critical that the appropriate kind of hydraulic element be chosen so that it can match the special requirements of your hydraulic system. The possibility of using hydraulic motor instead of a pump is something out my expectation and could result in failure to function properly in case this is done.
As such, I am wondering whether it is possible to use a hydraulic motor instead of a pump; thus may I kindly ask you if you can briefly explain whether this could happen and what are limitations or considerations?
Can a hydraulic motor substitute a hydraulic pump?
