PumpHouse is a suite of programs for the testing of pumps, publishing of predicted performance data, and the selection of pumps or impeller sizes for an application.
PumpTest does testing and keeps the results in a database. It can be used with a data acquisition system for automatic tests.
PumpPublisher
is used by an engineer to gather and filter test data for a particular
pump, then create a published performance curve and predicted
performance data. It has advanced features to easily create constant
efficiency curves (oak tree curves) and other graphic elements.
PumpSel uses
the predicted performance data to select a pump and impeller for a
given rating. It has many features such as series/parallel curves,
speed adjustment and multiple curve plotting.
PumpTest
PumpTest
PumpTest
performs automated pump testing and keeps the results in a database. Shop testers connect a centrifugal pump to a
testrig, prepare a data acquisition system, fill in some data, and then press
the “start” button. PumpTest controls
the valves and takes data at certain intervals.
The results of the test are compared to acceptance criteria, and the
test is also compared to published data and other historical test data as
needed.
PumpTest
improves upon other standalone test systems in these ways:
Historical tests are easy to
find using a search screen
The data is available to all users instantly
It is easy to compare a test to the expected performance
Pumps of the same size are easily gathered together to generate predicted data
It can be interfaced to several different kinds of data acquisition equipment
User-friendly interface for adjusting units, removing errant points, etc
Performs all calculations with a minimum of input data
PumpTest
reduces the process of testing a pump from 2+ hours to 30 minutes. The work of manually recording data (whether
typed or written) is handled by the automatic test. But, the biggest reduction in time is having
all historic data (20+ years, in one case) available instantly for comparison
or recall.
PumpPublish
PumpPublish
uses the data generated by PumpTest to create a set of average curves which are
used to determine the predicted performance for a pump. This predicted data is then used to calculate
the required pump and impeller size for an application. It does this by gathering together all the
test data for a particular size pump at a given speed, then correcting this
data into a series of diameters. This is
a familiar series of performance curves and most pump manufacturers publish
data in this way.
Many of
these curves are generated in drawing programs, such as AutoCAD or Canvas. These programs do not know how to adjust a
pump for speed or diameter changes, and they certainly can’t fill in the
constant efficiency curves (oak tree curves) automatically! PumpPublish improves over a “drawn” curve in
these ways:
Can add, remove or change info which is calculated (add a diameter, for instance)
Generate curves automatically: oak tree curves, constant power, constant NPSHR
Statistical functions to point out where some data may not be valid
Graphic-based editor to make adjustments, align curves and labels
Add labels and text which dynamically follow the data, especially with unit changes
Generate a printer-ready performance data sheet/curve
Output the results to be used for pump or impeller selection
PumpPublish
reduces the time of generating a pump curve from 2+ hours to as little as 15
minutes for well-behaved data. More
important, when changes or modifications are needed (create a companion 1485
RPM curve from a 1780 RPM curve, for example) you do not have to start from
scratch as you would with a drawing application.
PumpSel
PumpSel
uses the data generated by PumpPublish to select a pump and/or diameter in
order to meet a system requirement. It
works with a large database of pumps, many combinations of different units, and
is able to generate proposal curves with series and parallel curves or multiple
pumps on the same page.
Compared to
a different standalone impeller selection program, PumpSel has these
advantages:
Easy addition of data via the PumpPublish program, which also guarantees consistency
Size an impeller for pump, or select a pump and diameter from one or all families
Bearing life calculation, using hydraulic data for a pump and the locations of bearings
Shaft finite element calculation, showing a deflections and stresses for the shaft
Adjust efficiency for speed, add multiple pumps and system curves, show multiple speeds
Keep a particular selection for later recall, possibly for a proposal
PumpSel
prepares the calculations and makes a selection, but the final selection is
made by the engineer. By having a
variety of information available, it is possible to compare (and demonstrate in
a proposal drawing) several different characteristics or requirements.
