For optimum system air consumption and reduced maintenance
Filter Regulators are recommended for each pump at the wellhead to economize
on system air consumption, allow control of pump flow rate, and reduce
service needs caused by air system debris and contaminants.
These high quality filter regulators are coated on the inside to prevent corrosion from condensed moisture.
All QED well caps and flanges include mounting provisions for these filter regulators, and other mounting options are available.
Compressor Sizing
A compressed air supply is required to power AutoPumps. Estimation
of the fluid flow rates and air consumption of the AutoPumps and sizing
of the fluid lines, air lines, and air compressor involves a number of
factors. Our application specialists are ready to assist you.
The
flow rates and air consumption for the AutoPumps can be compared by
using the charts provided in the specs of each AutoPump model. The flow
rate and air use curves are based on pumping to atmospheric pressure at
the wellhead, and do not take into account any liquid piping system
backpressures due to elevation changes or fluid friction.
Finally,
there are some initial guidelines for air compressors. Most
importantly, follow all application guidelines of the compressor
manufacturer. A piston compressor may be a start/stop type or a
constant run type. The tank (receiver) must be large enough,
particularly for the start/stop type. The motor should not turn on more
times an hour than recommended by the manufacturer. And start/stop
compressors are typically assigned a 50% maximum duty cycle, meaning
that the compressor is sized to provide twice the maximum air demand of
the entire AutoPump system.
Rotary screw compressors
are designed for constant operation, and so are sized to just slightly
exceed the maximum air supply requirement; it is recommended that
rotary screw compressors not be grossly oversized because some types
may be damaged by continued operation at low partial capacity.
