Description
Educational Advantages
Designed to demonstrate the following:
- Normal pump inlet restriction
- Abnormally high pump inlet restriction
- Abnormally low pump inlet restriction
- What occurs when oil is discharged above the oil level in a hydraulic reservoir
- What occurs when the pump inlet is too close to the surface of the oil – vortex.
Learning Activities
The MF200-CAV Pump Cavitation Simulator will teach students the following:
- Physics associated with the operation of a hydraulic pump
- How the inlet side of a hydraulic pump works
- How design influences the amount of restriction at the inlet side of a pump
- Common design “oversights” when designing hydraulic pump intakes
- Why it is critical to know what a particular pump’s normal inlet restriction is
- What role altitude plays in the operation at the inlet side of a pump
- What causes pump inlet restriction to increase to a level that can cause cavitation, the most common cause of abnormally high inlet restriction
- What causes pump inlet restriction to decrease to a level that can cause pseudo-cavitation
- The most common cause of abnormally low pump inlet restriction
- What occurs when flow discharges above the oil level in a hydraulic reservoir
- What causes a “vortex” to occur in a hydraulic system
- Why it is critical to “trend” pump inlet restriction
