Resolving vibration problems in a crude booster pump

摘要

The pumps referred to in this article are 2,600-HP vertical pumps utilized as booster pumps for the shipment of crude oil. Each suction tank has two pumps (pump A and pump B) acting in parallel and receiving flow from a 60-in. pipe header (FIG. 1). The pump suction and discharge pipes are 42 in. The pumps are rated at 45,000 gallons per minute (gpm), with a minimum flow requirement of 12,000 gpm. Each pump has a separate 16-in. recycle line that returns to the 42-in. suction line. The pumps operate at 890 revolutions per minute (rpm) and are driven by electric motors.
