Oct 01, 2013

Before we get started, who is Xylem?

A company focused on water


We develop products and systems that:

-
Treat
water to make it potable (drinkable)

-
Transport
it to where it’s needed
(here’s where your solutions come in!)

-
Test
and analyze water

-
Clean
it for reuse after its many uses



We are a global company and our products can be found in every corner of the
globe in places
like:

Welcome to the
LSW challenge!

Goals of the challenge


Provide you with an exposure to water engineering problems


Expose your teams to the complete design process from concept inception
through cad and production


Support FIRST Robotics teams through opportunities to earn awards and
develop expertise without the burden of significant cost of participation


Overview of the challenge

We
are very excited to introduce you to the Let’s Solve Water Challenge. This
contest will allow you and your fellow students the opportunity to contribute to
solving one of the most important issues facing our world today
---
developing a
product that has the potential to
bring water
to the people who need it.


Water pumps, of all sizes and types, are what all of us depend on for the delivery
of water.


Your challenge, should you choose to accept it, is…

Building your own water pump

In this challenge you’ll be asked to modify
an existing pump to be
human
powered.

Not
all areas of the world are fortunate enough to have electric or fuel power. The
pumps developed in this challenge could potentially help solve some of the water
challenges faced by those in emerging markets around the world.


There are many aspects to pump design and performance and we’ve narrowed
our scope to 4 unique categories.


Your
pump will be judged
on Oct. 19
th

on
the following
:


Cost

calculated as cost per output
)

How the challenge works

We’ll provide you with…


A virtual kit of parts

-
Working model of diaphragm pump that can be used in CREO

-
PTC
Creo

software

-
PTC
Mathcad
software


A
pump and hose kit that
includes:

-
A diaphragm pump (
model
29270
-
0000)

-
A
sample hose

-
A
copy of this presentation

-
Access
to a Xylem mentor to assist with this
challenge


…you’ll turn it into

Use the resources available to develop a manual water pump that moves water
in the optimal way for design, time, exertion and pressure,

20 feet

More about diaphragm pump technology

Key Features


This type of pump is considered a positive

displacement
pump which uses a flexible

diaphragm
or membrane along with inlet and

outlet
control valves. The diaphragm is most

commonly
made of rubber or thermoplastic materials. The diaphragm or
membrane is reciprocated back and forth using a variety of drive options
(mechanical / electrical
)


Why it would make a good manual pump


Self
-
priming, good suction lifting characteristics, solids handling (slurries,
sludge), can handle viscous liquids & good run dry characteristics
.


Why it might not make the best manual pump


Flow tends to pulsate which can cause hammering effect. Inlet/outlet valve
requirements
.

The rules of the challenge

To qualify
for a prize:


Must use pump as supplied


Budget must be <$50 and be documented (keep receipts)
Note: used
assemblies will be assessed at 50% of new cost as determined by the highest
value found on the internet by the judges.


Any
tubing, fittings, fasteners, small bushings, hardware type items and raw
materials for fabrications may be purchased


Premade assemblies and components may be used, see the second bullet


Must connect to sample hose supplied


Pump system must operate on a lawn surface and may be wet, provisions for
“sinking” should be considered


Power
on competition day will be from a member on your
team, as selected by
the judges


All inquiries and replies will be open forum to all teams


Only one award
per
team


Judges rulings are
final


Play hard, think hard, learn and have
fun! Cooperation
and mutual
support between teams
throughout
the challenge is encouraged.

Presentations & selection of winners

October 19, 2013


All teams
will demonstrate
a working sample of
their pump


All teams will present a short (5
-
10 minute) PowerPoint presentation on their
development process,
challenges faced, and
what
was
learned in the
process.


Judges will select the team member from each team who will power the pump
on the day of the challenge (selected at Random):


All
pumps will be judged on
these 3 categories:

-
Cost (calculated as total cost)

-
CAD Design (
1
st
,
2
nd
)

-
Performance (1
st
, 2
nd
)

-
Most elegant design, A
panel of judges (Xylem staff & other water professionals) will
be responsible for all final decisions.


Invite your friends and family to join the fun!

-
We will invite local
media
to
the
event;
you might be asked for an
interview
