Variable Retraction Rate Pump and Method for Operating Same |
| 摘要 |
A pump system includes a pump and a storage volume in fluid communication with a discharge port of the pump. The pump includes a housing defining a pump bore and a pump piston disposed in sliding engagement with the pump bore, the pump piston being in selective fluid communication with the discharge port of the pump. A method for operating the pump system includes determining a time to drain an amount of a first fluid from the storage volume, and retracting the pump piston within the pump bore at a target retraction rate based at least partly on the time to drain the first fluid from the storage volume. |

1. A method for operating a pump system, the pump system including a pump and a storage volume in fluid communication with a discharge port of the pump, the pump including a housing defining a pump bore and a pump piston disposed in sliding engagement with the pump bore, the pump piston being in selective fluid communication with the discharge port of the pump, the method comprising:
determining a time to drain an amount of a first fluid from the storage volume; and retracting the pump piston within the pump bore at a target retraction rate based at least partly on the time to drain the first fluid from the storage volume. |
