Abstract
A system for automated testing of a high-pressure pump comprises a choke valve, actuator and actuator drive for operating the choke in response to receiving control signals. A system control unit includes a processor unit, system memory, I/O interface, human-machine interface, and display device. A pressure sensor is connected to the pump outlet line for sensing and reporting outlet pressure to the control unit. The control unit can execute a test phase by causing the pump to run at a test speed and causing the actuator to change the restriction value of the choke until a predetermined pressure is sensed in the outlet line and reported to the control unit. The control unit can cause the actuator to maintain the predetermined pressure for a predetermined period of time. The control unit can cause the display device to show a result or print a report of one or more test phases.
