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

syringe Used to determine time constant response

Time Constant

12-10-13 Team 14054 27

Pump

Vss found to be 0.00559 m/s

Measured distance off syringe

Time constant Eqn.

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 Control

Centrifugal 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

Smaller model available with ±0.25 L/min accuracy. ($75)

Mainstream Flow Feedback Loop

Using: P*V = n*R*TAssuming: ṁ1 = ṁ2

Q1 = Q2*[P2*T1/(P1*T2)]

IMPROVING VENTILATION

Vent: Current State Leaks Removal of all smoke Running during testing

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.

of unit

Misuse of Lighting method, Pump

overheating, electrical

short, cigarette ash 1 3 3

Have a fire extinguisher in room, proper use of lighting

method Megan

Salvage parts and rebuild

ASAP

Risk assessment

4

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

5

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

Faulty data, no data, noisy

data, equipment

failure, electrical

shorts

Improper coating,

improper wire gauge, burn

out near heat source,

improper grounding 2 1 2

Double check against schematic Gideon

Salvage parts and rebuild ASAP

7Collision of

moving parts

Damaged equipment,

pinch hazards, technician

injury

Improper programming, faulty sensors, power surge 2 1 2

Manually test system Jose

Risk assessment

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

salvage parts and rebuild ASAP

9 Contamination

Faulty data, equipment

destruction, lab hazards

Leaks in tubing, faulty seals,

backflow, improper

sterilization 2 3 6

Insuring proper seal, checking from pressure drop, use

of hand-held smoke detector Matt

Disclaim that data may be faulty and pursue methods of

improving

10 Power failure

No data, uncontrolled

cigarette burn, no user interface

Power grid failure, breaker trip, computer

unplugged from wall 3 1 3 Secure power cord Megan Plug back into wall
