Mechanics of Piston Vs. Worm Screw Pump
12-10-13 Team 14054 22
Piston Vs. Worm Screw Pump• ISO standard.• Servo controlled.• Creates a smoother
puffing profile.• Sinusoidal puffing profile
with constant motor speed.
• DC step motor controlled.• Theoretically more
accurate puffing profile.• Steady state puffing profile
with constant motor speed.
Servo Vs. Step Motor
12-10-13 Team 14054 24
Cost of Servo Motors• “A typical Techno servo gantry system sells for about $2,700
more than a stepper system.”• “[servo motors] tend to be10% to 30% more expensive than
similar stepper systems. Brushless servo motor systems tend to be 50% to 100% more.”
http://www.techno-isel.com/Tic/H834/PDF/H834P041.pdf
Browsing online cost range: $250-$5,000.
Pump
Talked with Dr. Kempski Devised a simple test to determine Restricting Parameters
for dynamic response A measured mass simulates required force to move

F – Fsystem is the same as ‘mg’ from the test
‘m’ measured to be 0.4137 kg
12-10-13 Team 14054 28
Pump Time constant Eqn.
Evaluating through, need to estimate carriage weight ‘m’
Estimated 0.3 kg Time constant is
0.000413 sec Under worst case of m=1 kg,
τ = 0.00137 sec
12-10-13 Team 14054 29
Pump Pump specs (NE OEM 570)
Able to reach 45 mL/s Valid for normal cigarettes Matched sent flow rates
Unable to test dynamic response (time too reach) flow rates Looking at E-cig’s
Need to reach ~120 mL/s Pump DOES NOT MEET REQUIREMENT
12-10-13 Team 14054 30
Resolution of NE-570 Syringe Pump• Syringe sizes: Up to 60 cc, 140 mL partially filled• Motor steps per revolution: 200• Microstepping: 1/8 to 1 depending on motor speed• Motor to drive screw ratio: 60/15• Drive screw pitch: 16 rev/in• Advance per step: 3.96875 μm to 31.75 μm depending on motor speed• Syringe diameter: ~37.5 mm
Volume per step: (31.75 μm)[1/1000 mm/μm]*pi*((37.5 mm)/2)^2= 35.07 μL/step = 0.03507 mL/step
EcoFlo• Machines have Wifi and Bluetooth to connect to• Machines can not replace sidestream centrifugal pumps
because the flow rate is too high• EcoFlo
• 5 – 100 CFM in 1 CFM increments
• Replace side stream pump• Only need 3 L/min = 0.1 CFM• Machine is too large to replace• Syringe & centrifugal pump exhale into unit
• Machines can easily be used for ventilation

Blower Status Screen
Note: EcoFlo has 2 blowers. This means that it can draw more air than it is supplying causing a negative pressure chamber. This way smoke does not leak out of chamber.
Sidestream Flow ControlCentrifugal pump controlled by flowmeter to
3 L/min.
Key Instruments FR4A40BVBN ($95):• Range: 0.4-5 L/min• Accuracy: ±3% of Full Scale = ±0.15 L/min

Impinger• Impiger most likely filled with methanol for all tests• Impinger may be surrounded by dry ice or liquid nitrogen to
motivate particles to condense• Cooling the impinger is not needed for vapor phase, e-cigs.• Other cigarette studies have inserted “a small plug of quartz wool
and soda lime glass balls filled to a depth of approximately 6cm. The impingers are held in a polystyrene box filled with sufficient dry-ice to cover the main body of the impinger.”
● Notable design challenge:○ If a liquid nitrogen bath is needed then a sufficient bath
container will be needed
IR Sensor Experiments
• Failed to get past IR sensors to work.• Talked with multiple professors with no luck.Question for customer:• Would you like to buy new IR sensors for the
automatic termination of the cigarette at its butt or terminate the cigarette after a set number of puffs?
• Past IR sensors were bought for $175 but we would recommend researching more robust IR sensors.

Smoke containment
failure
Fire alarm goes off, health concerns
Improper sealing, poor ventilation,
improper use of system 2 1 2
Use of hand-held smoke detector,
proper ventilation,
proper sealant, possible time
delay for opening door Eric
Increase lab ventilation

Fragile equipment
failure
Faulty data, no data, expensive
to replace, injury during
removal
Transportation, recklessness, proximity to heat source,
pump vibration 2 3 6
Use of Proper Protective
Equipment, insulate fragile
equipment MattSalvage parts and
rebuild ASAP
6 Faulty wiring

8 Pump failure
No flow, experimental
failure, expensive to
replace
Loss of power, improper
filtering, over use, incorrect
gauging, improper set up 1 1 1
Proper filtration, proper cleaning, proper cooling Eric
Troubleshoot problem then
