2 Topics to be discussed: Abstract Introduction Principle of operation Materials to be used Sectional view of assembly Design Future benefits Disadvantages Applications Conclusion

3 ABSTRACT The project work is aimed to design, fabricate and analysis of dual peristaltic pump. This pump is having a capability of pumping two different types of fluid to two different positions at same flow rate or at different flow rate. This pump is efficient at lower speed and also economical.

4 INTRODUCTION A peristaltic pump is that, which transfers fluid via an elastic tube by squeezing the elastic tube with pair of rollers to elastically deform the tube. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow cause pressure.

5 PRINCIPLE OF OPERATION

6 MATERIALS TO BE USED CASING-ACRYLIC MATERIAL ROLLER- POLYPROPYLENE TUBE-SILICON MATERIAL END RODS-STEEL

7 SECTIONAL VIEW OF ASSEMBLY

8 TUBE TESTING Experimentally it was found that force required to compress the flexible pipe completely so that there is no water leakage= 4 Kg =4x9.81 = 39.24N ≈ 40 N

9 STRESS ANALYSIS

10 BEARING DESIGN Experimentally it was found that force required to compress flexible pipe =7 Kg = 7x9.81 = 68.67N Total force acting on rotor= 68.67+6 = 74.67N ≈ 75N Radial load on bearing (Fr)=75/2 =37.5N Axial load (Fa)=0N

11 DYNAMIC EQUIVALENT LOAD W=X.V. F+Y. Fa where, V=rotation factor X=1; Y=0; V=1(from table inner race rotation) W=1x1x37.5+0 W=37.5N CONCIDERING LIGHT SHOCK ON BEARING, Service factor (Ks) =1.5 Design dynamic equivalent load=1.5x37.5 =56.25N

12 PUMP ELEMENTS

13 ASSEMBLY

14 FEATURE BENEFITS OF PERISTALTIC PUMP Fluid does not contact any part of the pump except the tubing. No Seals to leak Pumps liquids, gases, solids, or mixed phases Can use one continuous piece of tubing from inlet to outlet Some tubing materials can be easily sterilized. Easy and fast product change—simply change tubing—no cross-contamination Operates in any position (orientation insensitive). Wide range of flow rates Many types of tubing are available. Multiple channel applications.

15 DISADVANTAGES chemical compatibility pressure The flexible pipes wear out frequently

16 Dual peristaltic pump Other pumps Simple in construction Multiple task operated No rusting problem Light in weight Noiseless operation Minimum number of parts Easy maintenance Complex in construction Single operated Rusting problem Heavy in weight More number of parts Maintenance problem COMPARISON BETWEEN DUAL PURPOSE PUMP WITH OTHER PUMPS

17 INDUSTRIAL APPLICATIONS Biotechnology Chemical industry Cleaning Construction Environment Food Printing industry Pulp and paper Textiles Waste water treatment Water treatment Pharmaceutical industry

18 CONCLUSION It is observed that, this type of pump has high volumetric efficiency, but it is also found while experimentation that, this pump works in low head. So this pump can be used only for low heads. The main drawback of the pump is that the flexible pipes wear out frequently. This type of pump is best suited when a sealed pumping system is required where there is no contamination of the pumped fluid. This pump can efficiently pump fluids like water, paste, oil, liquid chemicals etc.
