🔍 Key Concepts

• This is a vane-type positive-displacement pump with an eccentric rotor and spring-loaded vanes • Many positive-displacement pumps can operate as hydraulic motors when fluid flow and energy direction are reversed • Pay close attention to the inlet and outlet ports (arrows 6 and 7) and how the rotor would move if fluid entered under pressure

💭 Think About

• If this unit is used as a pump, which port is the discharge (high‑pressure) side, and which is the suction (low‑pressure) side? Now imagine you supply high‑pressure fluid to one of those ports—what will happen to the rotor? • Does converting a pump to a motor usually require changing the basic internal geometry (rotor diameter, vane type), or mainly reversing how the fluid is applied? • Look at the roller/sliding vanes and springs: would they still be able to follow the cam ring and seal the chambers if the direction of torque is reversed?

✅ Before You Answer

• Identify clearly which arrow (6 or 7) shows present discharge flow in pump service, and which is suction • Decide which port must receive pressurized fluid to develop torque on the rotor in motor service • Confirm whether any of the suggested modifications (changing vane type or rotor size) are actually necessary for the device to rotate when pressurized fluid is applied

The device illustrated is considered to be a pump. Which of the following statements is true if it is to be used as a hydraulic motor? See illustration GS-0074.

Pressurized fluid would have to be supplied to the existing indicted casing outlet.

Roller vanes would have to be exchanged for sliding vanes.

The diameter of the rotor would have to be increased.

Nothing could be done to convert this device to a hydraulic motor.
