• Down-Thrust Alarm/Fault Detection – Apollo monitors the pump operation for excessive down-thrust.
Limits for both Alarms (creates an Event in the Event Log/can be programmed to signal a digital output)
and Faults (Faults the system) are monitored.
In addition to the protections provided by the pump curve, the pump curve also allows Apollo to calculate the
fluid flow rate through the pump.
11.4
Setting up the Pump Curve
From the Home Screen, navigate as follows to the Pump Curve Setup menu.
Home Screen-> Settings-> MENU-> Other Initial Setup-> Right Arrow-> Pump Curve Setup
When you first navigate to the Pump Curve Setup menu, only the
“Setup Pump Curve” wizard is shown.
Press the Select function button to walk through the pump curve configuration.
Information needed by the Pump Curve Setup wizard:
•
Units for Calculated Flow
: Options are barrels per day (BBL/Day), cubic meters per day (m3/Day),
and gallons per minute (GPM).
•
Units for the Pump Head channel
: Options are Feet and Meters.
•
Units for the Power channel
: Options are Horsepower (HP) and kilowatts (kW).
•
Units for Differential Pressure
: Options are pounds per square inch (PSI), Bar, kiloPascals (kPa),
megaPascals (MPa).
•
Pump Manufacturer and Model
•
Number of pump stages
•
Pump Type
: Options are Floater, Compression, and SPS.
•
Water Specific Gravity:
– If you plan to use Viscosity Compensation, enter the specific gravity of the water in the Oil/Water
mixture being pumped.
– If you do not plan to use Viscosity Compensation, enter the specific gravity of the Oil/Water mixture.
•
If Viscosity Compensation is used, you will also have to enter:
– Water Cut
– Oil Specific Gravity
– Well Fluid Viscosity
– Viscosity Method
◆
Options are Viscosity Compensation Disabled, Pump Curve Interpolation Method, Hydraulic Institute
Method.
– Flow Adjustment Factor
